1 Introduction
GuardNVR is a unique digital video surveillance solution, which combines three major
functions in one Network Video Recorder (NVR) or Digital Video Recorder (DVR): local
digital recording, multiplexing and simultaneous transmission of the video via existing
networks (TCP/IP). To a standard GuardNVR, up to 20 cameras can be permanently recorded
while multiple operators at different locations on the network are accessing the GuardNVR
network video server.
Being a networked device, GuardNVR utilizes two basic principles of the
Internet/Intranet technology:
ƒ GuardNVR works over the TCP/IP network protocol, which provides maximum
connectivity. This means that the existing computer network infrastructure can be
used eliminating extra installation expenses.
ƒ GuardNVR uses a web-based user interface to view live images, recordings, etc.
More specific it uses Microsoft Internet Explorer.
Remote and Local Monitoring
To remotely monitor the connected cameras, the
GuardNVR uses Web Browser technology. To
locally monitor video, the GuardNVR also
provides a local interface via a PC monitor
directly connected to the GuardNVR. This local
interface allows an operator to see live video
from the connected cameras without the need for
additional client computers on a network.
Continuous Activity-Based Recording
By default, a GuardNVR continuously records all images from all the connected cameras
based on activity detection. In this case, only movement is recorded. If there is no movement,
no recording takes place. If necessary, the GuardNVR can be set to record continuously.
Intelligent Storage Option
GuardNVR uses a first-in/first-out (FIFO) overwrite principle. Once the disk is full, the oldest
images are overwritten.
Semi-Continuous recording (recording based on activity detection) allows a GuardNVR to
store pre- and post-alarm video. Pre- and Post-alarm images are often more important than the
Version 4.3 Series
GuardNVR Installation Manual
5
images at the time of the alarm event itself. Up to 5 minutes of pre- and post-alarm video can
be stored per event.
GuardNVR makes a distinction between common activity recordings and pre/post alarm
recordings. In the way that, alarm recordings have a higher storage priority and will not be
overwritten by non-alarm recordings.
The GuardNVR is operational even when no live monitoring occurs. While the
GuardNVR continuously records images from all the cameras, video is transmitted
from the server to the client only when an Internet browser is connected to
GuardNVR and someone is live-viewing images from one or more cameras.

Installing GuardNVR.
Starting up for the first time.
GuardNVR in the network.
Testing GuardNVR.
2.1 Work space conditions
Establishing a comfortable and appropriate work site and placement of the GuardNVR is
important to you and your GuardNVR. Proper ambient conditions should also be maintained
for the GuardNVR’s operation. This section discusses the following topics:
ƒ
ƒ
General conditions
Placement conditions
2.1.1 General conditions
Carefully read the following guidelines:
ƒ
Make sure there is adequate space around the GuardNVR for proper ventilation. Leave
ample ventilation room for the cooling fan. Do not block the vents. If your unit is
placed in a lockable enclosure, be sure to use only enclosures that are fan cooled and
ensure that the fan is operational. It is also a good practice to place the GuardNVR in
the middle of the cabinet to maximize air flow.
ƒ
Make sure the AC power cord connects to an outlet that is close to the GuardNVR and
easily accessible.
ƒ
Make sure the Ethernet cable is correctly connected and is laid properly, without strain.
ƒ
The temperature should be 5 to 40 °C (41 to 104 °F) and the relative humidity should
be 5 to 95 %.
ƒ
Avoid areas where rapid or extreme changes in temperature or humidity may occur.
ƒ
Keep the GuardNVR free of dust, moisture and exposure to direct sunlight and away
from heat sources, such as electric heaters.
ƒ
Do not use the GuardNVR near liquids or corrosive chemicals.
ƒ
Some components in the unit, including data storage media, can be damaged by
magnets. Do not place the GuardNVR near magnetic objects or bring magnetic objects
close to the GuardNVR. Be careful of objects, such as stereo speakers, that produce
strong magnetic fields during operation.

2.1.2 Placement conditions
Position the GuardNVR and peripheral devices to provide comfort and safety.
ƒ
Set the GuardNVR on a flat surface at a comfortable height and distance. If the monitor
is connected it should be no higher than eye level to avoid eyestrain.
ƒ
Do not place any liquid containers on the GuardNVR system, such as water, coffee, or
beverage. If liquid is poured onto the GuardNVR, it can cause a system malfunction or
fire.
ƒ
Prevent the power cable from being severely bent by a heavy object. This may cause
fire.
ƒ
Clean the dust around the GuardNVR on a regular basis. When cleaning the system,
always use a dry cloth. Do not use wet cloth or other organic solvents. This may
damage the surface of the GuardNVR and may cause system malfunction or electric
shock.
ƒ
When pulling the power cable from the plug, do so gently. Do not touch the plug with
wet hands and avoid using the plug if the holes on the outlet are too loose. This may
cause fire or an electric shock.
ƒ
Do not attempt to disassemble, repair, or modify the GuardNVR yourself. It is
extremely dangerous due to high voltage running through the GuardNVR. This may
cause fire, electric shock, or serious injuries.
ƒ
Keep at least 15cm (6inches) between the back of the GuardNVR and a wall for the
cables connected into the GuardNVR. Otherwise, cables may be bent, damaged, or cut.
This may cause fire, electric shock, or injuries.
ƒ
The power outlet must be grounded, and the voltage range must be within 10% of the
voltage rate. Do not use the same outlet with a hair dryer, iron, refrigerator, or any
heating appliances. This may cause fire, heating, and an electric shock.
ƒ
Do not place any heavy object on the GuardNVR system. This may cause system
malfunction.
ƒ
The GuardNVR can be damaged from a strong impact or vibration. Avoid throwing
objects within the vicinity of the GuardNVR.

2.2 GuardNVR IIS Split
As stated before, the GuardNVR application is a real web application which increases the
flexibility and connectivity considerably. This web application is managed by IIS (Internet
Information Services) which is installed on a computer of choice which can run IIS.
Versions prior to version 4.0.8.0 only have the ability to install IIS on the Video
Server itself.
By having the option to install the web application (by using IIS) onto a computer of choice, it
is possible to simplify the connection and scalability of the global security installation as the
server itself and the web application don’t have to be installed on the same unit.
Setup Type Selection Screen
There are three possible options:
ƒ Video Server with User Interface Server (default) – Both the video server and the
web application will be installed on the unit. Option Typical (single server) or first
option in the Custom menu.
This is the default installation and recommended if you have only one GuardNVR
system.
ƒ Video Server without User Interface Server – Only the Video Server is installed.
This means you have installed the Web Application (User Interface) on another system.
Option Custom (multiple severs).
ƒ User Interface Server without Video Server – Only the Web Application is installed.
Ideally this web application will be used as the central web application for all the
GuardNVR systems in your network. Option Custom (multiple severs).
You can choose one of the three options during the installation of your system by
selecting Custom. Ask your installer for more information if you didn’t install the
system yourself.

Centralized IIS Server on a Video Server
Let us explain how this works in reality!
If you have multiple Video Servers installed and have installed a centralized IIS server (On
one of the Video Server or even on a separate PC), then you can connect to each Video Server
by connecting first to the centralized Web Application by typing the IP of that unit. At that
time you can choose which server you want to connect to in the network from the extended
logon screen. In this case you only need to remember one IP address to connect to all your
GuardNVR servers.
This means that when you connect to a Video Server that also has the Web Application
installed you will need the basic logon screen shown below:
Basic Logon Screen
If you want to connect through the centralized Web Server, you have to use the extend logon
screen by clicking Options. There you select or type the video server IP or DNS name:

2.4.4
Setting time
For proper functioning of GuardNVR, it is very important to use the appropriate Time Zone
setting because the movie recordings are always stored in local time This can be done in two
ways, or by the GuardNVR application configuration (See GuardNVR User Manual
Chapter 3.3.10 Time Synchronisation), or by the Windows OS configuration.
We strongly advise you to use the GuardNVR application way as this is the easiest
way to configure your time settings.

2.4.4.1 Through GuardNVR Web Application
Time synchronization allows you to synchronize time on all devices connected to your unit
(e.g. cameras) and synchronize your server with a specific time server. This can be done by
going to the Settings menu in the Video Manager Web Application and selecting the Time
Synchronisation link in the top bar
Time Synchronization Screen
There are three options:
ƒ
Use video server as a (proxy) time server – The unit will synchronize with an
external time server if configured in the bottom part of the screen. If empty, the unit
will act as a time server for itself and the connected devices (e.g. cameras).
ƒ
Synchronize all devices with an external time server – The unit and all the
connected devices (e.g. cameras) will be synchronized with an external time server.
Configure the IP address or DNS name of the external time server in the bottom part of
the screen.
ƒ
Manually configure time synchronization on each device separately (not
recommended) – No synchronization at all is performed, neither for the unit nor for
the connected devices (e.g. cameras)
If your unit is part of a domain, this menu will not be available. The unit and
connected devices (e.g. cameras) will be synchronized automatically with the Active
Directory of the domain.

Optionally the installer/user can configure a GuardNVR to synchronize its time and date
automatically on a regular basis using a so-called ‘Time Server’. These special servers exist
often on bigger corporate networks or on the Internet. To set this up, follow the steps below:
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ

Click Settings -> Control panel.
In Control Panel, in the left upper corner click the ‘Switch to Classic view’ link.
When in classic view, select Date and Time from the right-hand list.
On the Date and Time properties dialog, select the tab ‘Internet Time’ (XP) or click
‘Change Settings’ (Vista).
Check the box ‘Synchronize with an Internet time server’.
Enter the name or IP-address of a known time server into the 'Server' edit box. Note
that when using a name in the IP-address settings of the GuardNVR server, a correct
DNS IP-address should be supplied. Otherwise this name will never be resolved/found.
If you use an IP-address there is no need to provide a DNS server.
Click OK to save the ‘Internet Time’ changes.
The default Internet Time Server is time.windows.com; however you can use other
time servers for synchronization, such as those provided below:
ƒ time.nist.gov (IP-address: 192.43.244.18)
ƒ utcnist.colorado.edu (IP-address: 128.138.140.44)

2.5.4 Firewall configuration
The following ports need to be opened for connections going towards the
GuardNVR:
1. TCP Port 80: http
2. TCP Port 1518: GuardNVR control connection
3. UDP Ports 4096 till 4223: GuardNVR video streaming
4. TCP Port 3389: Remote Desktop connection (Optional). Frequently asked by
support when you have an issue)
RTP uses two UDP ports per stream (versus one in the old streaming format in
versions prior to V4.0.0.0), one for RTP (the video stream itself) and one for RTCP
(QoS signal stream), limiting the software to a maximum of 64 concurrent streams.
This number can be limited (e.g. for security purposes) or extended using the Settings
> Network settings page. In that case, Quadrox recommends you to open a number of
spare ports to avoid switching issues, e.g. 4 ports extra. The first port in the range
should be even.
Like all applications which communicate over networks, GuardNVR uses communication
channels to pass data (commands, video, web-pages, etc …) back and forth. The network
language that the GuardNVR uses is called TCP/IP. This is not a unique language but a
Version 4.3 Series
GuardNVR Installation Manual
25
family of related network languages, called network protocols. These TCP/IP protocols are the
network protocols used on the Internet and on most networks throughout the world today.
GuardNVR uses two protocols specifically: TCP and UDP.
A communication channel on a TCP/IP network can be represented as a tunnel with two
endpoints. The two programs communicating with one another are each said to be at each
endpoint. These endpoints are called ports.
When the two programs communicating with one another are not located on the same
corporate network (like most communication between a program on a client PC and a program
running on another computer on the Internet), often there is some kind of guardian device in
between them. These guardian devices are called Firewalls. Their job is to guard all network
communication between the corporate network and the Internet and block certain unwanted
communications while allowing the desired communication to pass.
There are several levels on which a firewall can guard network communication. The most
common way is to allow or disallow certain ports to be used, depending on which applications
are allowed to communicate.
A firewall guards a port in a certain direction. Communication that is initiated from the
Internet towards the corporate network is called incoming traffic, while communication from
the corporate network towards the Internet is called outgoing traffic. Note that the initiation of
the communication is important: once a connection is made, data can be transferred in both
directions.
Let’s apply this principle to GuardNVR network communication. The GuardNVR client (the
ActiveX component embedded in Internet Explorer at the client machine) will try to create
network connections to the GuardNVR server. The eventual result of these connections will be
video data streaming from the GuardNVR server to the GuardNVR client, but since the
GuardNVR client initiates them, they are referred to as connections towards the GuardNVR.
From the client perspective, it is outgoing traffic, while for the server it is incoming traffic.
In order for the GuardNVR to function correctly, the appropriate ports need to be
opened for communication towards the GuardNVR.
There are three port configurations to perform:
1. TCP Port 80: to allow external users to see the web interface (HTTP traffic). This port
is usually opened by default.
Some ISPs block port 80. Please inform yourself.
2. TCP Port 1518: to allow external users to receive alarms, control PTZ cameras, send
commands, etc. This is called the GuardNVR control signal.
3. UDP Ports 4096 till 4223: By default the GuardNVR uses a range of UDP ports to
transport video streams. These UDP ports are not listening all the time. The GuardNVR
software enables them at random to enhance security.
Typically when the UDP ports are not opened correctly, the user only sees the webinterface but no live images.
Version 4.3 Series
GuardNVR Installation Manual
26
To allow Quadrox support personnel to get remote access to the GuardNVR, TCP Port
3389 needs to be opened for Remote Desktop Connection or 5500 for VNC.
A firewall can be placed on several positions in the network. The most common place is at the
edge of the corporate network, or in other words between the corporate network and the
Internet. Recently it also became popular to place a firewall to protect the network traffic from
a single computer. A firewall that is placed between the computer and the network is referred
to as a ‘Personal Firewall’ application.
In practice, a corporate network firewall is often integrated with the router connecting the LAN
and the internet. For more information on routers, see the section on connecting the
GuardNVR to the internet. A personal firewall is software running on the computer that it
protects. Personal firewall applications can be installed separately but are also included in the
Windows XP operating system (Service Pack 2) or Vista and in many virus protection
software packages.
There are several scenarios where firewall configuration is necessary:
1. A user on a corporate network or at home behind a broadband router wants to access a
GuardNVR on the Internet
2. A user on the Internet wants to access a GuardNVR on a corporate network.
These situations are explained in more detail in the section on how to connect your GuardNVR
to the internet. If a user on a corporate network wants to connect to a GuardNVR on another
network, a logical combination of these two situations can be applied.
1. A user with a personal firewall application on his computer wants to access a
GuardNVR on the corporate network or on the Internet.
2. There is a personal firewall application installed on the GuardNVR.

2.5.6.2 Router and firewall
To fully understand this section it is important to know what the difference between a router
and a firewall is.
A firewall is the piece of software that takes care of guarding the network communications.
Sometimes the term ‘firewall’ refers to the machine performing firewall tasks. This is
confusing and in fact incorrect: normally a firewall is not a piece of hardware, but a program
running on that hardware.
A router is a piece of hardware that embodies the physical connection between two different
networks (e.g. your local network and the Internet). It redirects (“routes”) data so that it arrives
at the correct place. A router is a hardware device, but its functionality is controlled by
software that runs on the router.
Sometimes the routing functionality is provided by a proxy server, bridge or gateway. While
these are not the same as routers, they can be considered as such for the discussion in this
document.
Router software can have firewall capabilities. In other words, the router software
can have, apart from its normal capability to connect two networks and redirect data,
the capabilities of inspecting, allowing, and denying certain network communication.
As an example, most broadband routers (ADSL, SDSL, cable modems, etc)
nowadays have firewall capabilities and are also being used as such.
In the following schemes the firewall and the router are depicted as two different
entities (nodes on the network), but know that they could be one and the same node
in practical cases.
2.5.6.2.1
Configuring router
The router that forms the connection between the corporate network and the Internet needs to
know which internal machine it has to send network traffic to.
For example, a client machine on the internet requests a connection on port 1518 (the port for
GuardNVR video commands), using the public IP address of the router. The router then needs
to know to which device on the corporate network it needs to send this connection request, in
this case the GuardNVR. So the router needs to know the local IP address on the corporate
network of the GuardNVR. Configurations for different brands and models of routers in the
field can be found in:
Web Resource for Router Configuration and Setup:
http://www.portforward.com/routers.htm
Version 4.3 Series
GuardNVR Installation Manual
31
Networking Tips:
http://www.portforward.com/network.htm
If you don’t already have a router you will need to purchase one and configure it as part of you
network.
Useful commands
ipconfig – utility to see computer IP properties
ipconfig /release – release the current IP address – need DHCP enabled
ipconfig /renew – renew the IP address by telling the router that it needs DHCP enabled
ipconfig /all – show all IP config properties
ipconfig /? – show help on IP config
ping – utility to test the connection with other IP address
ping 192.168.123.254 – attempt to ping IP address by sending a small packet
ping –t 192.168.123.254 – continually ping IP address until you close command window or hit
Ctrl+C.
DHCP – Dynamically assign IP address to requesting devices (e.g., computer, camera). This
means when you connect a computer to the router the computer will automatically negotiate an
IP address from the router.
Port Mapping – Section on router where you specify which port will be mapped to which
device. With a router you are sharing a single Internet connection with multiple devices and
for the cameras you need to have each camera on a separate port if you want to access the
camera from outside the router (i.e., Internet).
2.5.6.2.2
Configuring firewall
General information about firewalls and their configuration is given in a previous section. The
most important notes are:
The following ports need to be opened for connections going towards the
GuardNVR:
1. TCP Port 80: http
2. TCP Port 1518: GuardNVR control connection
3. UDP Ports 4096 till 4223: GuardNVR video streaming
In order for the GuardNVR to function correctly, the appropriate ports need to be
opened for communication towards the GuardNVR.
The following port needs to be opened for connections going outwards from the
GuardNVR:
1. TCP Port 3389: Remote Desktop Connection port. This port is used in support
cases only.
RTP uses two UDP ports per stream (versus one in the old streaming format), one for
RTP (the video stream itself) and one for RTCP (QoS signal stream), limiting the
software to a maximum of 64 concurrent streams. This number can be limited (e.g. for
Version 4.3 Series
GuardNVR Installation Manual
32
security purposes) or extended using the Settings > Network settings page. In that
case, Quadrox advises to open a number of spare ports to avoid switching issues, e.g.
4 ports extra. The first port in the range should be even.
Let’s apply this to the two situations in which a GuardNVR is accessed over the Internet.
The blue, yellow and red arrows in the following diagrams indicate the direction of the initial
network connection request, and thus the direction in which the ports should be opened in the
firewall.
Situation 1 – A user on a corporate network or at home behind a broadband router
wants to access a GuardNVR on the Internet
The user on a corporate network wants to access GuardNVR over the Internet. The main
concern is: will the corporate firewall allow the GuardNVR network traffic?
The client computer makes the initial connection to the GuardNVR server. The firewall should
allow data going out of the corporate network to the GuardNVR. The appropriate ports should
thus be opened for outgoing data.
Note that not all of the UDP ports are used all the time. However, since the GuardNVR
software assigns them randomly, the exact ports cannot be known beforehand. The network
administrator should open the full range of UDP ports.
Version 4.3 Series
GuardNVR Installation Manual
33
Situation 2 – A user on the Internet wants to access a GuardNVR on a corporate network
The user is connected to the internet and wants to access a GuardNVR, which is located on a
corporate LAN (Local Area Network). The main concern is: will the corporate firewall allow
the incoming GuardNVR network traffic?
The client computer makes the initial connection to the GuardNVR server. The firewall should
allow data coming in to the corporate network to the GuardNVR. The appropriate ports should
thus be opened for incoming data.

2.6 Testing GuardNVR
2.6.1 Local client test
A local client test is very useful, to test whether the video server is running correctly on its
own. Because we don’t use any external network facility, no configuration in that direction can
cause a live-viewing problem. Perform this test first of all to check the stand-alone operation
of the GuardNVR video server.
For local client testing, follow the steps below.
1. On the desktop of a GuardNVR, you’ll find an icon ‘Video Browser’. Double-clicking
this icon will open a Microsoft Internet Explorer window.
2. The IP address (e.g.: http://192.168.100.1) to where this Internet Explorer has to
connect looks like ‘http://localhost/guardnvr/browser’. This is a standard way of telling
Internet Explorer to connect to the webserver on the same GuardNVR, so not going
over the network but staying within the boundaries of its own Operating System.
3. When accessing the GuardNVR video server application from a client PC for the first
time, Internet Explorer will ask you to install and run an ActiveX component (Video
Client Component). Follow the on screen instructions to install the component.
If you have problems installing the ActiveX, please make sure first that you have
added the server to the trusted site list of Internet Explorer.
4. A welcome screen should now appear. Normally you would be prompted for a login
and password but because you’ve already authenticated to get access to the Windows
Operating System, and you will not be prompted again for a Login and Password.
5. By default the live-view pages are opened and the user can verify whether all the
cameras are transmitting a good image.
2.6.2 Connection test
Open a command prompt window by clicking Start, select Run, and type CMD. Once the MS
DOS window is open, type ping <Computer Name>.
ƒ
ƒ
ƒ
ƒ
If you see the text ‘Reply from XXX.XXX.XXX.XXX’ (as shown in Picture A), the
network connection is fine.
If you see the text ‘Ping request could not find host <Computer Name>. Please
check the name and try again.’, there is a physical network connection problem.
Contact your Network Administrator.
If you see the text ‘Request Timed Out’, there is a physical network connection
problem. Contact your Network Administrator.
If you see the text ‘Destination host unreachable’, the IP address settings of either the
client computer or the GuardNVR, is inconsistent (different subnets). Contact your
Network Administrator.

Checking Physical Connection Screen
2.6.3 Remote client test
For remote client testing, follow the steps below:
1. Open a Microsoft Internet Explorer window.
2. Fill in the IP address (e.g.: http://192.168.100.1/guardnvr) or domain name (e.g.:
http://guardnvr.mycompany.com/guardnvr) in the address bar.
3. When accessing the GuardNVR from a specific client computer for the first time,
Internet Explorer will ask you to install and run an ActiveX component (Video Viewer
Component). Follow the on screen instructions to install the component.
If you have problems installing the ActiveX, please make sure first that you have
added the server to the trusted site list of Internet Explorer.
4. A welcome screen should now appear, and you will be prompted for a Login and
Password.
After filling in Logon and Password you should be logged on to the GuardNVR Web
Application.
‘http://192.168.100.1/guardnvr’ is the factory default IP-address for the EU version
of GuardNVR. For US customers the factory default IP-address is
http://192.168.0.199/guardnvr. Please note that your installer could have changed it
to fit the specifications of your own network.

3 Upgrading & Restoring GuardNVR
3.1 Upgrading GuardNVR software
The GuardNVR software (and related installed components: Alarm, POS…) can be upgraded
at all times when a new version is available and this without losing your settings and
recordings. This is done by the the ProductUpdate tool and works for version 4.0.4.0 and
higher. The ProductUpdate is a standalone InstallShield-based application that updates the
currently installed GuardNVR application to the most recent version.
You can request this tool for free by contacting [email protected]
3.2 Saving and Restoring configuration
It is advisable to save the settings after the configuration process on a save place or medium
such as a blank CD/DVD. When performing an upgrade or a complete system restore, you can
use this configuration file to restore the GuardNVR configuration quickly and easily. You can
restore any version starting from version 4.0.4.0.

4 Advanced topics
4.1 Extending storage space
You are able to add new hard disks to your GuardNVR server to increase movie storage
capacity (this both inside or ouside the GuardNVR unit case). The following two sections
describe how to first physically and after that logically add new storage space. The example
focuses on adding one extra hard disk inside a GuardNVR Ser ver with an Windows XP OS.
Other configurations are similar.
4.1.1 Adding hard disk
In order to add a hard disk to the GuardNVR, follow the steps below:
1. Make sure the GuardNVR is turned off completely by removing the power cable from
the power supply at the back of the GuardNVR.
2. Remove the top cover.
3. Place the additional hard disk near the old one in the special tray.
4. Connect one side of a flat IDE cable to the second hard disk and the other side to the
second IDE slot on the motherboard. In case of SATA, the procedure is similar.
5. Connect power cable to the hard disk.
6. Check the proper setting of the hard disk jumper. Both hard disks have to be configured
as master when connected to two different IDE cables. If they are connected to the
same IDE slot the main hard disk is a Master, the additional hard disk should be Slave.
Please set the jumper to the Slave position. This step can be skipped if you use SATA.
To correctly configure the jumper settings, please visit the web site of the respective
Hard Disk manufacturer:
HITACHI:
www.ghst.com
MAXTOR:
www.maxtor.com
SAMSUNG:
www.samsung.com
SEAGATE:

WESTERN DIGITAL: www.westerndigital.com
7. Close the top cover.
8. Turn on the power of the GuardNVR and make sure that the message that a new hard
disk drive is detected appears. Normally you will be asked to save the new settings.

4.2 Video Client Component (ActiveX)
Having a correct installation of the Video Client component is an essential part of a successful
GuardNVR installation. Problems like black images appearing, no images appearing at all and
errors in Internet Explorer can be the result of an incorrect Video Client Component
installation.
This Video Client Component is based on ActiveX technology. ActiveX is an architecture that
lets a program (the ActiveX control) interact with other programs over a network (such as the
Internet). In our case the Video Client Component communicates with the GuardNVR and
shows video images.
An ActiveX control can be integrated into various environments like a web page. When an
ActiveX is integrated into a web page as in the GuardNVR web application, the first time a
client machine accesses this web page with Internet Explorer the ActiveX needs to be
downloaded and installed on the client machine. At this stage there are several potential
problems for the installer to be aware of:
ƒ
ƒ
ƒ
ƒ
The Windows user account under which this web page is accessed doesn’t have enough
rights to install the ActiveX component on the client system. This results in not seeing
images at all.
The security settings of Internet Explorer prohibit the installation of the ActiveX. Add
the site to the Trusted sites before installing the ActiveX.
Spyware blockers or anti-virus programs don’t allow the installation of an ActiveX on
the client machine.
The Video Viewer ActiveX utilizes various other Windows System components. If any
of these system components are incorrectly installed or not present, at all the ActiveX
will fail to install or work incorrectly.
It is important that the ActiveX installation is monitored carefully. This has to be
performed only once during the first time that the GuardNVR web application is
accessed. If something goes wrong during this installation, a user can end up with an
incomplete installation of ActiveX.

4.3 Changing network ports
This chapter explains how to change different network ports, which are used by a GuardNVR
system.
4.3.1 Changing GuardNVR video ports
GuardNVR ships with the default UDP port range set to 4096 – 4223, which are used for video
streaming. You may either decrease or increase this range, for that purpose you should change
the amount of opened UDP port on your router, firewall and on GuardNVR itself. To change
GuardNVR UDP ports go to Settings->Network Settings.
The amount of UDP opened ports have to correspond to number of camera streams
you want to have simultaneously. For instance, you have GuardNVR with 4
connected cameras, if you launch two GuardNVR clients of GuardNVR
simultaneously 16 camera streams will be created (i.e. 4 camera streams for each
client) and this doubled because of RTP streaming method. So you have to open 16
UDP ports. You have to use even numbers for the start and end port of the UDP
port range.
4.3.2 Changing TCP port
GuardNVR ships with the default TCP port set to 80. By maintaining the default setting
GuardNVR may be accessed remotely by simply entering either the local LAN address (if
accessed from within the network) or the static IP address if accessed from outside the
network. If this port needs to be changed, follow the steps below.
1. Logon as Administrator.
2. Double Click the Support folder from the Windows desktop and select Internet
Information Services by double clicking.
3. Proceed through the following path <Computer Name> (local computer)->Websites
and right click Default Web Site. Select Properties.
4. Under the Web Site tab you will find a section Web Site Identification. Change the
TCP port to the desired value and click OK to confirm.
When you make a change to a TCP port other than port 80, there are some implications that
must be taken into account.
ƒ
ƒ
When you access GuardNVR locally by selecting Video Browser from the desktop, the
link http://localhost/guardnvr/browser is launched. This link with have to be renamed
as follows if a value other than port 80 is used: http://localhost:xx/guardnvr/browser
where xx is the value that you selected.
When you access GuardNVR from Internet Explorer remotely you would do so by
selecting http://xx.xx.xx.xx which is your static IP or internal IP address assuming you
Version 4.3 Series
GuardNVR Installation Manual
50
are using port 80 as the default. When you change to a new value, you must now enter
http://xx.xx.xx.xx:yy where yy is the new TCP port setting.
4.3.3 Changing remote desktop port
GuardNVR ships with the default remote port set to 3389 that should be forwarded in your
router in order to be able to access the unit via remote desktop. If this port needs to be
changed, follow the steps below.
1. Logon as Administrator.
2. Double Click the Support folder from the Windows desktop and select RegEdit by
double clicking.
3. Proceed through the following path HKey_Local_Machine->System->Current
Control Set->Control->Terminal Server->Winstations->RDP-TCP Select RDPTCP.
4. After selecting RDP-TCP, scroll down the list in the right pane until you come to Port
Number. Double click Port Number to Edit.
5. On the pop up screen select Decimal under Base and then enter the desired value in the
Value box.
6. Click OK to confirm.
7. Be sure to enter this value in the port forwarding section of your router.
A system reboot is typically required after making registry changes. Check also your
firewall settings. The new port must be added to the exception list.
4.4 GuardNVR power on after power failure
To adjust the GuardNVR server to power on again automatically after the power failure, you
must configure the BIOS to go to previous state after power loss. This can be done by entering
the BIOS during the initial stage of the machine booting.
4.5 Configuring audio over the Internet
GuardNVR supports specific audio functions for the following brands:
ƒ
ƒ
Axis – Listen in and speak:
o M1031-W
o P1311, P3301(-V), P3343(-V/VE), P3344(-V/VE)

o KX-HCM110(A)
o BB-HCE481(A)
o BL-C101(A), BL-C111(A), BL-C131(A), BL-C210(A), BL-C230(A).
o BB-HCE481(A)
o BL-C101(A), BL-C111(A), BL-C131(A).
If the installation has a LAN connection, GuardNVR connects to a camera for audio grabbing
via the internal address you specified in a camera wizard. If you want to have audio from the
camera over the Internet you need to make additional router configuration.
Audio is disabled by default if you add a camera. To enable audio, read the User
manual.
The following ports should be opened on the router, if not already opened:
ƒ
ƒ
ƒ
TCP Port 80: http
TCP Port 1518: GuardNVR control connection
UDP Ports 4096 till 4223: GuardNVR video streaming
The ports mentioned above are used by GuardNVR ActiveX controls. Since the audio feature
operates through the camera’s native ActiveX controls (which are installed during the first
switching to the camera in Live view) and not the GuardNVR ActiveX and is grabbed from the
camera directly a new port for the camera ActiveX controls should be configured as follows:
ƒ
ƒ
ƒ
ƒ
Assume that 192.168.1.1 is the camera internal ip-address;
Assume that 64.160.1.1 is the router external/public ip-address;
Assume that 6000 port is any free port on your router;
Assume that 80 port is opened on the camera;
Based on the assumptions above the addressing should be as follows:
64.160.1.1:6000 should be addressed to 192.168.1.1:80
When the router configuration is complete go to the Camera Wizard to add/edit the camera(s)
with audio feature, add external IP-address and port you configured as shown on the picture:

5 Storage / Bandwidth considerations
Digital video that captures several days or weeks comprises a massive amount of data. If you
want to store this data or stream the video over a network, there is a need to reduce the size,
because storage devices (hard disks) and networks are limited in capacity.
The size reduction of digital video data is called compression: it is a mathematical algorithm
(called a codec) that is applied to the data. The algorithm carefully removes information that is
less important for a human viewer. Because information is lost, inevitably the quality of the
videosdf is affected.
There is a trade off between the quality of the video and performance of the system on the one
hand, and data size, the compression technique and its parameter on the other hand. The
explanation below will help you to make the best choices depending on your specific needs
and situation.
For the calculation of an estimate of how long you can record in your situation, refer to the
online storage calculator on our website:
http://www.webcctv.com/start.asp?main=perf_wizard
5.1 Terminology and basic video technology
This section provides an overview of the terms used in the following sections and the basic
underlying technology. It is important that you understand these concepts in order to
understand the influence of different factors on quality and size.
A digital image consists of an array of image points, called pixels. The amount of points in
horizontal and vertical directions is the image resolution. Each image point has a certain
colour and brightness attached to it, and is represented inside the computer as a number.
If there are more points in an image (higher resolution), more detail will be preserved in the
image, but also the necessary space or bandwidth increases.
Digital video consists of series of digital images displayed one after the other. Each image is
called a frame, and the speed at which images are displayed is called the frame rate. This
number is indicated in frames per second (fps).
If more frames are displayed (higher frame rate), objects in the video will move smoother, but
also the necessary space or bandwidth increases.
Each number in a computer is represented by a number of 1’s or 0’s, called bits. The amount
of data that a digital video contains per second is called the bit rate. This is usually expressed
in kilobits (1024 bits) per second (kbps).
For uncompressed video, the bit rate is calculated as:
Resolution x frame rate x colour depth (amount of bits per pixel)
Version 4.3 Series
GuardNVR Installation Manual
53
Example: 5 fps of full D1 PAL video:
Bit rate = 768 x 576 pixels/frame x 5 frames/second x 24 bits/pixel
= 53084160 bits/second
= 50,6 Mbps
To illustrate the amount of data that this figure represents, let’s see how much uncompressed
video we can record on a standard machine with a 250 GB hard disk.
Recording time = 250 Gigabyte x 8 bits/byte x 1024 Megabit/Gigabit / 50,6 Mbps
= 40474 seconds
= 11,2 hours
This number needs to be divided by the number of sources (cameras) that we want to record on
1 system. This is of course unacceptable for a modern video surveillance recorder, which is
why we need video compression.
When we stream live video, the video data has to be transported over the network. The
capacity of the network to transport data is called bandwidth. It is also expressed in kilobit per
second (kbps). For network streaming, the rate at which video is transported is more important
than the total amount.
When storing video on a hard disk or other storage device, the total storage time is limited by
the capacity of the disk. This capacity is determined by the total amount of data that a disk can
contain. This is expressed in megabyte or gigabyte.
Please note that for streaming we use kilobit while for storage we use megabyte.

GuardNVR Installation Manual

5.2 Factors that influence bit rate and video
quality
There are several factors that have an influence on the amount of data (bit rate), the quality of
the video and the performance of the video recorder. The most important factors are explained
in this section.
5.2.1 Compression technique (codec)
The biggest influence on quality and data reduction comes from the algorithm that is used to
compress the video. Over the years, many algorithms have been conceived, but they can be
roughly categorized into two groups:
1. Intra-fame coding: each frame is compressed independently of the other frames (e.g.
MJPEG).
2. Inter-frame coding: since frames are usually very similar, this information is used to
further reduce the video size (e.g. WMV, MPEG, H.264)
Inter-frame MPEG-like coding can lead to a bigger compression (typically up to 10 times more
video for the same size), resulting in more storage or less bandwidth requirements for the same
quality. However, the calculations are more complex, so the performance of the encoding
machine will be lower (less streams, more CPU usage).
In general, there is a big difference in performance between doing the compression on the
recording device and doing it on the camera or any other specific compression hardware (e.g. a
network video server). The latter is highly recommended.
When choosing a particular compression technique, there may be other considerations. For
instance, WMV video can be played on any PC running the Windows operating system and on
most other devices with video capabilities (e.g. PDA, phone, etc).
Quadrox recommends:
1. For analogue cameras connected to an internal capture board: use WMV7.
2. For network cameras and network video servers: use the native format in
which the device streams (no recompression on the recorder).
The chosen compression technique also has an influence on the following discussion.
1. For intra-frame codecs (MJPEG), the quality is usually set by a parameter. As a
consequence, frame rate and resolution have a direct influence on the resulting bit rate.
2. For inter-frame codecs, the bit rate is usually a parameter. As a consequence, frame rate
and resolution don’t have a direct influence on storage and bandwidth requirements,
although they might have an influence on the quality of the resulting video.
This means that when the bit rate increases, the resolution will decrease as well as the frame
rate. All these parameters together produce a better image quality.
Version 4.3 Series
GuardNVR Installation Manual

5.2.2 Resolution
When the compression technique is based on JPEG images, a second big factor in data size
reduction is the resolution. As mentioned before, compression works by selectively reducing
the amount of information in the image. One way to do that is to reduce the size of the image.
Example:
A VHS quality image (PAL) of 384x288 pixels can be considered as a SVHS+ image of
768x576 pixels where you throw away every other pixel in either direction. This reduces the
data size by a factor of 4.
Of course, this influences the quality of the image. Especially fine details are more likely to get
lost, like face characteristics or details of clothing.
The resolutions that are mentioned, except for the mega-pixel, are for the PAL
standard. NTSC images and pure digital images might have a slightly different
resolution, but in general the same steps/magnitude apply.
Postage stamp format (192x122). This resolution is offered by some of Quadrox competitors.
At this image size however, most of the information in the image is lost. At best, one would be
able to count the number of people in the image, but there is no hope for e.g. identifying faces.
VHS quality (384x288). Small and thus favourable for storage and transmission, this
resolution gives a good quality in most cases.
SVHS quality (768x288). In this image format, only half of the image is lost. The image is
only decimated in the vertical direction. For analogue based cameras, this is the maximum
resolution possible without motion artefacts (see below). Best choice for an analogue camera.
Notice that this resolution doesn’t have the classical 4:3 proportions. This can be compensated
for, but some media players might display a “squished” image.
SVHS+ quality (768x576): This is the maximum resolution for all analogue and most network
cameras currently in the market. Most detail is preserved.
This resolution has a big disadvantage though. Because of the video sensor technology inside
the camera (interlacing), the image shows horizontal lines at the edges of moving objects. This
makes the object (e.g. a face) unrecognizable in most cases and as such seriously diminishes
the usability of the camera.
For more detailed technical explanation about interlacing and its consequences,
please contact Quadrox support.
Megapixel quality (1280x960 and higher): Network cameras with more than a million pixels
are becoming the new type of camera’s in today's marketplace. Because of their high pixel
count, they can preserve much more detail than a regular camera, making them useful in many
circumstances. This comes at a very considerable storage and network bandwidth cost!
As a final remark on resolution, we should reiterate that resolution has quite a different effect
when using inter-frame codecs for compression (MPEG, WMV). In these cases, choosing a
smaller resolution means less quality (as above), but not less data, since the bit rate is fixed.
Version 4.3 Series
GuardNVR Installation Manual
56
For a fixed bit rate, a higher resolution means that information has to be removed in other
ways, reducing the image quality.
Keep in mind that choosing a higher resolution also means putting a higher load on
your GuardNVR and may reduce its performance. Bigger images need more internal
resources like memory and processing time.
5.2.3 Frame rate
When choosing a resolution, we reduce the amount of data by reducing the size of an image.
Similarly, we reduce the amount of data by simply storing or streaming fewer images. Frame
rate is a third big factor in compression. This factor is potentially big, since the difference in
frame rates can range from 30 fps to one image every 3 seconds, a factor of 100!
When reducing the frame rate, the loss of quality creates video that is not “smooth”. The
human eye needs a certain frame rate to perceive a sequence of images as smooth motion.
When reducing the frame rate to a number below this amount, the image “shocks”. However,
while being less pleasant to look at, the quality of the individual images is not affected, so all
detail is preserved.
The threshold of the human eye for perceiving a sequence of images as smooth motion lies at
about 15 images per second, depending on the person. Although the broadcast industry
(television, DVDs, film, etc) take a substantial margin on this with streams at about 25 fps, this
is not absolutely necessary for smooth motion.
Because of this, streaming at more than 15 fps is almost never useful and mostly serves to
increase your bandwidth requirements. In most cases, even 10 or 12 fps suffice for a
satisfactory viewing experience.
For recording, frame rate is usually reduced further, since nothing much occurs in the time
period of 1/15th of a second. A storage frame rate of 3 to 6 fps is enough for most practical
applications.
Similar remarks about the relation between compression technology and frame rate hold as
they did for resolution. When using (M)JPEG, frame rate has a direct influence on bit rate
since each image is compressed separately. When using MPEG, H.264 or WMV, the bit rate is
set, so frame rate potentially has an influence on quality rather then on data size.

5.2.4 “Differential” live streaming
In order to further reduce the bandwidth requirements for live streaming, Quadrox engineers
have devised an extra algorithm that can improve the JPEG streaming for analogue cameras.
When using differential live streaming, only the parts of the image that actually change
visually are transmitted to the viewing component. At the receiver side, the parts of the image
are recombined into a full image. In terms of quality, this form of data size reduction can
hardly be noticed, but the bandwidth is reduced drastically. This allows us to stream high
quality video over a lower quality bandwidth.
If you want to remotely access the GuardNVR video server over the Internet, it is
highly recommended to use differential streaming. Another possibility is using Low
Bandwidth streaming. More info can be found in the User Manual.
This feature is not available for network cameras. Low Bandwidth streaming is
available for both analogue and network camera’s.
5.2.5 Activity detection for storage
For storage, we can apply a similar principle. Only the images that have meaningful activity in
them need to be stored. When nothing is happening, recording can be suspended. To better
distinguish meaningful activity from “background movement” (e.g. a street nearby, a moving
tree), masking can be applied to take only certain parts of the image into account.
This technique not only reduces the storage requirement, but also makes it much easier to trace
important events in the recordings afterwards, saving you both money (hardware) and time.
Using activity detection is highly recommended in almost all cases. Typically, it allows you to
increase storage time up to 400%. For cameras with little motion, e.g. in an empty hallway in
an industrial facility, it can even reduce the storage space to about 1% of the original volume!

6 Security Policy
This chapter describes guidelines for proper use and a security policy, which are designed to
ensure the proper functioning of a GuardNVR video recorder and to provide a guideline for
protection against hackers, viruses, malware and other forms of electronic attacks.
Quadrox will not support any problems that arise from not complying with the guidelines and
policies in this chapter.
This chapter is structured in three major parts.
First, the guidelines for proper use of GuardNVR are explained. GuardNVR is a dedicated
system that should be used solely for the purpose of video recording and surveillance.
Secondly, the details of the security policy are outlined. To sum it up in a single sentence, the
policy amounts to this: We will lock down GuardNVR as much as possible, leaving as few
places as possible where an attack could occur, and securing the remaining places as much as
possible. We will provide you with information about how we lock the machine and how you
can open it if necessary. As mentioned above, Quadrox will not support this any further.
Thirdly, some additional ways to recover from errors are explained for your convenience.
6.1 Proper use of GuardNVR
GuardNVR is a dedicated system that should be used solely for the purpose of video recording
and surveillance. Since the GuardNVR server has Windows XP/Vista as its operating system,
it can be accessed locally and used as a normal PC. There are several precautions, which
prevent improper working of the system.
GuardNVR software should be used in conjunction with dedicated software (i.e. such usage
should be agreed to with Quadrox) or with software that doesn’t cause:
ƒ
A high CPU and memory load on the GuardNVR server (i.e. CPU consumption,
memory of all types consumption, etc.), which could hinder the proper working
(including video quality) and could shorten the uptime of GuardNVR server software.
ƒ
The installation of viruses, spyware, adware, malware and other forms of software that
form a threat against the health of GuardNVR server software.
ƒ
GuardNVR server software malfunction (if such consequence is known beforehand).
The precautions put above will help to increase the security and ensure proper functioning of
GuardNVR throughout its lifetime.

6.2 Security policy
At the start of this section, let’s repeat the basic premise of the GuardNVR security policy:
Lock down GuardNVR as much as possible, leaving as few places as possible where an attack
could occur, and secure the remaining places as much as possible.
“Locking down” the GuardNVR means that you should try to prevent malicious attacks on
GuardNVR by not giving attackers (hackers, viruses, etc) the possibility to exploit weaknesses
in the system.
GuardNVR uses the Microsoft Windows XP/Vista operating system. Like any other operating
system including Linux and other Unix variants – or any software for that matter – this
operating system is not perfect. It contains certain weaknesses that could be used to get
unauthorised access to the machine.
Generally speaking, Windows XP/Vista is a very safe operating system when administered
correctly. There are several ways outlined in this section to increase security.
ƒ
ƒ
ƒ
ƒ
ƒ
Have secure passwords.
Don’t leave GuardNVR under the administrator account logged on.
Keep the system up to date.
Secure the network access.
Make sure that any other access doesn’t cause problems.
Contrary to popular believe, most attacks on computer systems are not brute-force attacks by
extremely skilled people on a weak operating system. Instead, most attacks exploit
vulnerabilities that were created “from the inside”. This implies that you have control over the
situation and can prevent attacks by rigorously securing the machine and being careful when
handling it. In the next paragraphs, you can find out how to do this.
6.2.1 Password policy
The very first thing that you should do after installing GuardNVR, is to
change the Administrator password!
To avoid passwords leaking out of the organization or being retrieved otherwise, follow these
guidelines:
ƒ
Publish passwords to as few people as possible. The fewer people knowing the
password, the less chance of it ending up with the wrong person.
ƒ
Don’t keep passwords in written form in places that might be accessible by malicious
people. This includes paper documents that might get lost, websites, mail and IM
messages.
Version 4.3 Series
GuardNVR Installation Manual
60
ƒ
Restrict the number of Administrators to a minimum. Since users have fewer rights, a
user password leaking has fewer severe consequences. It is even advisable to have an
extra user account for each administrator, which should be used for regular viewing.
ƒ
Choose strong passwords. A strong password is a password that is hard to guess by
attackers (people and software). This helps to secure the product against brute force
attacks (trying all passwords). Use the following guidelines:
o
o
o
o
The password should be at least 8 characters long. Longer is better.
Use both CAPTIAL and small letters (at least one of each).
Use both letters and figures or other characters (at least one of each).
There should be no connection whatsoever between the username and the
password. This includes copying parts of the username or having a
semantically relevant meaning (e.g. the password is the name of the user’s
wife). Preferably, the password should have no “human” meaning at all.
One of the prime ways for hackers to retrieve passwords is simply asking for it. A hacker
would pretend to be e.g. a support technician and ask you for the password. In order to prevent
this kind of attack, we outline here the procedure for Quadrox support people regarding
passwords of customers.
First of all, by default Quadrox does not know any passwords of machines in the field. Since
we use the operating system for authentication, there is no way in which we can retrieve a
password, for any reason. The only way for us to know a password is if the customer
voluntarily tells us.
If it is necessary for Quadrox support to have the password in order to give assistance, the
support technician will ask the customer to call the general Quadrox support number or use the
official [email protected] (.be) address. This way, the customer is sure that he tells the
password to the correct person.
When you have the slightest doubt about the authenticity of the support person, the requested
way of communicating the password or the telephone number given to call, please don’t
hesitate to call Quadrox support on the following number: +32 (0)16 58 25 85. For USA
customers, please call 1-888-QUADROX.
The Quadrox support personnel will not save or keep passwords in any way. For optimal
security you should change the password after a support call, or in general after revealing the
password to anyone who normally doesn’t have access.
Default passwords should be changed as soon as possible, preferably even before GuardNVR
is put on the network. Otherwise attackers can gain access to the system using easily
retrievable passwords. It’s like locking the door, but leaving the key in the lock.

6.2.2 Windows security updates
To keep your system secure, it is important that you keep it up to date. This will prevent an
attacker from using vulnerabilities that have already been removed by Microsoft.
Quadrox is not responsible for keeping the installed GuardNVR software and Windows OS up
to date. This is the responsibility of the installer. Quadrox is not responsible for problems that
originate from not keeping the machine up to date (patches until the last release applied). If
such a problem occurs (e.g. a virus), Quadrox will recommend a full re-installation.
6.2.3 Network security
The network is the main interface of GuardNVR, through which an attack can occur. That’s
why it is important to pay special attention to its security.
In accordance with our general security policy, we will try as much as possible to limit the way
in which the network can be used, while not interfering with GuardNVR functionality. There
are several ways to limit the network:
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
Physical limitation (dedicated network)
Limiting the number of connections (LAN versus Internet)
Using only one network protocol (TCP/IP)
Allowing only traffic on the necessary network ports (Firewall)
Allowing only known clients
Limiting the functionality of the web server (securing IIS)
6.2.3.1 Dedicated network versus integration with the
corporate network
Having a dedicated network for video surveillance, adds an intrinsic level of security by
physically eliminating access points for attacks. This way, you can easily have a safe and
robust system. The network becomes a safe entity in itself, while if GuardNVR is incorporated
in a more general network, security should be built around the GuardNVR server.
A dedicated network also ensures that the video traffic doesn’t interfere with other general
data. This potentially increases the performance of both GuardNVR and other applications on
the network.
On the other side, integrating the video network with the corporate network can potentially
reduce the costs of installation and administration. Both solutions are possible and endorsed by
Quadrox. The choice depends on your performance, cost and security needs.
Version 4.3 Series
GuardNVR Installation Manual

6.2.3.2 Connecting GuardNVR to the Internet
When GuardNVR is in a LAN, the number of network nodes from which an attack can
originate is at most a couple of hundred. When GuardNVR server is connected to the Internet,
this number rises to millions instead. Connecting GuardNVR to the Internet dramatically
increases the chance on an attack.
The choice of putting a unit on the Internet depends on the needs of the end user, but if you do
so, please pay extra attention to the security issues mentioned in this document.
6.2.3.3 Limiting the number of protocols
By default, the Windows operating system supports multiple network protocols. An example is
NetBios which is, among other things, the protocol used to share folders across the network.
To increase security Quadrox recommends disabling these protocols on a GuardNVR server.
Only one protocol is recommended to be enabled: TCP/IP. This is the main protocol used on
most of the current networks, including the Internet, and the only one needed for GuardNVR
functionality.
Disabling other protocols prevents attacks that use them and it is in that sense a good measure
to increase security. Furthermore it prevents the unit from broadcasting, or in other words
constantly yelling its position to the rest of the network. This makes it more difficult for an
attacker to find the unit on the network, which again increases security.
In some exceptional cases it might be necessary to enable these protocols again, e.g. to backup
video through shares. This is technically possible: the protocols are disabled, not removed.
However, Quadrox strongly advises against this practice and will not give support on this
functionality or any problems that originate from it.
6.2.3.4 Firewall
A critical element in GuardNVR security is the firewall. A firewall is a piece of software that
basically allows only a limited number of applications to use the network.
GuardNVR may use Microsoft firewall, which is enabled by default in the Microsoft XP SP2
and Vista operating system. It is a basic firewall with limited functionality, but none the less
effective for our goals.
Only the following applications are recommended to be allowed:
ƒ
ƒ
ƒ
Web server needed for the web application (IIS, TCP port 80)
GuardNVR video server software (OPServer and OPVWSYS, TCP port 1518 and UDP
ports 4096-4223)
Remote desktop needed for remote administration and support
This is only valid for connections that are made to GuardNVR. For outgoing connections
(connections made from GuardNVR server to another machine) there is no restriction.
However, please follow the guidelines for proper use to prevent problems.
Version 4.3 Series
GuardNVR Installation Manual
63
In some exceptional cases it might be necessary to allow more applications (open more ports).
This is technically possible; however, Quadrox strongly advises against this practice and will
not give support on this functionality or any problems that originate from it.
6.2.3.5 Allowing only known clients
If you have a set-up with a fixed number of known clients, there is a possibility to only allow
these clients, based on their IP address. No other clients will be allowed to access GuardNVR.
This would further limit the number of possible connection points and thus increase security.
This is only usable in a limited number of scenarios and can give rise to a number of logical
problems. Please contact Quadrox support for more information.
6.2.3.6 Securing the applications
When applying the restriction on applications with the firewall such as explained above, the
attackable points are effectively limited to those applications. In the next step we should make
sure that those applications themselves are secure.
Remote desktop doesn’t have ways of automation. This implies that only a human operator can
use it, not a piece of software like a virus. The risk of a human operator performing malicious
actions is limited to the access he has. The security of this falls back to the security of the
passwords, for which a policy is outlined above.
The GuardNVR server is an unlikely point of attack, since it is not a wide spread application
like a web server. This means that very few people would be interested in designing an attack
on this software. Those people would have to know a lot about the internal workings of the
server, which is difficult. This being said, Quadrox engineers are working hard to keep the
number of possible security risks to an absolute minimum.
Only one application remains, namely the web server (IIS). Quadrox uses tools issued by
Microsoft like urlscan and lock-down to block any action that is not related to GuardNVR
functionality. To ensure security of IIS, please make sure that all necessary security updates
are applied (see above).
6.2.3.7 VPN
Setting up a virtual private network (VPN) can potentially increase security, similar to having
a dedicated network or limiting the clients on IP address. It uses encryption of data that goes
over the network to achieve this goal.
Setting up a VPN for your video surveillance equipment is outside the scope of Quadrox
support. Be aware that the encryption process can cause delays that might affect the
performance of the video system.
Version 4.3 Series
GuardNVR Installation Manual
6.2.4
64
Other types of access
Apart from the network, there are several other ways in which a malicious piece of software
can end up on GuardNVR. These ways include all information carriers that can be connected
to GuardNVR servers, like CDs, floppies and USB memory drives.
When connecting these information carriers to GuardNVR server, pay special attention to
security. Make sure that they are scanned for viruses and malware before connecting them.
Along the same line of reasoning you should pay extra attention when you introduce foreign
objects in a shielded environment, e.g. a laptop of a technician in a dedicated video network.
6.2.5
3rd party security tools
When the machine is locked down like described above, it should be resistant against the
majority of threats. The limited increase in security that would be achieved by pre-emptively
introducing additional security tools probably does not justify the additional cost of licenses
and efforts for installation and maintenance. Furthermore, this software might interfere with
the functionality of GuardNVR.
Such tools include virus scanners, malware/spyware/adware removal tools, additional pop-up
blockers, firewalls with extended functionalities, script blockers, etc.
As a general guideline, script blocking should be disabled at all times, since GuardNVR uses
scripts to implement its functionality. The 3rd party tools also need to allow the proper
installation and execution of signed ActiveX components.
6.3 Error recovery mechanisms
GuardNVR has the ability to automatically recover from common problems like crashes,
overheating, etc. This is achieved through: System Health Service (SHS).
System Health Service is software running on GuardNVR as a service. It monitors the
hardware and some vital processes on the machine, like the GuardNVR server and IIS. If
something happens (e.g. a crash) to any of these processes, the SHS will try to recover by –
depending on the seriousness of the situation – restarting the process or rebooting the PC.

7 Troubleshooting
GuardNVR is a reliable system and is designed and tested for durability. However, problems
may occur, following procedures in this chapter can help to determine the cause.
You should become familiar with this chapter. Knowing what might go wrong can help
prevent problems from occurring.
7.1 Problem solving process
Resolving problems will be much easier if you observe the following guidelines:
ƒ
Stop immediately when you recognize a problem exists. Further action may result in
data loss or damage. You may destroy valuable problem-related information that can
help solve the problem.
ƒ
Observe what is happening. Write down what the system is doing and what actions you
performed immediately before the problem occurred.
The questions and procedures offered in this chapter are meant as a guide, they are
not definitive problem solving techniques. Many problems can be solved simply, but
a few may require help from your installer. If you find you need to consult your
dealer or other consulting person, be prepared to describe the problem in as much
detail as possible.
7.1.1 Preliminary checklist
Consider the simplest solution first. The items in this section are easy to fix and yet can cause
what appears to be a serious problem.
ƒ
Make sure you turn on all peripheral devices. This includes your printer and any other
external device you are using.
ƒ
Before you attach an external (none USB) device shut down the GuardNVR. When you
turn the GuardNVR back on it recognizes the new device.
ƒ
Make sure all options are set properly in the corresponding setup program.
ƒ
Check all cables. Are they correctly and firmly attached? Loose cables can cause signal
errors.
ƒ
Inspect all connecting cables for loose wires and all connectors for loose pins.
ƒ
Check that your CD/DVD-ROM is correctly inserted.

7.1.2 Analyzing the problem
Sometimes the system gives clues that can help you to identify why it is malfunctioning. Keep
the following questions in mind:
ƒ
Which part of the system is not operating properly: keyboard, hard disk drive, optical
media drive, or display? Each device produces different symptoms.
ƒ
Is the system configuration set properly? Check configuration options.
ƒ
Do any indicators light? Which ones? What colour are they? Do they stay on or blink?
Write down what you see.
ƒ
Do you hear any beeps? How many? Are they long or short? Are they high pitched or
low? Is the GuardNVR making any unusual noises? Write down what you hear.
Record your observations so you can describe them to your dealer.
