Launching Nx Witness in Compatibility Mode
It is necessary sometimes to connect to Server with different versions. A good example would be when
Nx Witness is installed at multiple sites (home, work, etc.) and only one installation is upgraded. In this particular case, Servers will have different versions and one Client should connect to another Server
(Client at home connects to Server at work). Servers of different versions are highlighted in red in login dialog.
In this case, the following message will appear:
You are about to connect to Server which has a different version.
Would you like to restart client in compatibility mode?
By clicking OK, the application will restart in compatibility mode.
In some instances, it may be necessary to download additional files for compatibility pack. In this particular instance, the following message will be displayed:
You are about to connect to Server which has a different version.
Client version X is required to connect ti this Server
Download version 2.2?
Once download is completed, restart is suggested.
Note: Nx Witness recalls the Server it was last connected to and automatically suggests compatibility mode for the next launch.
IMPORTANT. If some of the components of the Multi-Server System such as Server or Client have different versions installed, it may cause potential issues. When Client is connected to Server, all component versions are checked. The warning will appear if the component versions differ from one another.
It is recommended to have the same version installed on all system components. See Upgrading Nx

Introducing User Roles
There are three types of user roles in Nx Witness:
·
Owner (user with "
admin
" login). Unlimited control. This user cannot be deleted.
·
Administrator. Full control, except:
·
Change Super Administrator (admin) settings
·
Delete or change own role
·
Viewers (Live Viewer, Viewer, Advanced Viewer). Limited control. A viewer cannot:
·
Manage users (except for changing their own password).
·
See servers and all connected cameras. Only the cameras assigned by the administrator are visible.
·
Change predefined layouts (layouts can be changed, but cannot be saved); however, it is possible to configure and save own layouts based on available resources (assigned cameras and local files).
Additional permissions can be assigned to users to be able to operate with available cameras (assigned by Administrator):
PERMANENT VIDEO WALL CAM SETTINGS PTZ ARCHIVE EXPORT LIVE
Admin
Administrator
Adv. Viewer

Live Viewer
·
View archive, perform search and forensic analysis
·
Perform export from archives
·
Set up cameras
·
Set up PTZ on cameras
·
Create, modify and delete Video Walls .
If none of these permissions are assigned, a user can only view live videos on available cameras.
IMPORTANT. If any action or graphical element described in this document is not available to a specific user level, the following will apply (Admin only). If the action described in this document is unavailable to certain roles, it will be indicated in the corresponding topic.
The following represents a standard flow:
1. Super Administrator creates and configures all layouts for own use.
2. Super Administrator creates several users with a Viewer role.
3. Super Administrator creates and configures layouts for each Viewer.
4. Viewer logs into Nx Witness and is only able to work with assigned layouts and cameras.

Nx Witness Quick Start
Obtaining and Activating Nx Witness Licenses
Nx Witness’s license policy is quite simple. Each Camera requires License. The application has no camera count restrictions.
The License allows viewing and recording of a single Camera. Cameras can be viewed live without
Licenses allowing for an unlimited number of Cameras to be connected and viewed live at no charge.
Note: If recording is enabled for Camera License is considered used even if recording is not performed
( icon in Tree). Recording is required to capture
events on
Camera.
For instance, the following screenshot illustrates the situation that all Cameras are offline and not recording. However recording is enabled on four Cameras (marked by ):
In this case 4 Licenses are being used.
See also "
Setting up Recording Schedule ".
Additionally there are Video Wall Licenses. Each one allows controlling video wall from a single computer
(one session) or extend Video Wall on 2 displays. For instance 4 licenses allow user to display Video Wall on 8 monitors and control it from 4 clients concurrently.
Nx Witness comes with four Trial Licenses automatically (do not allow Video Wall feature). Trial Licenses are active 30 days only.
IMPORTANT: In Multi Server System Licenses are activated on a certain Server (the one Client is currently connected to - icon). If this server is offline, those licenses will be invalidated until the server is back online. If licenses are activated on different servers, they will be combined if those servers are merged into a single system.
To activate Trial Licenses:
–> System Administration (CTRL+ALT+A).
2. Go to Licenses tab.
3. Click Activate Trial License.
If Trial License is about to expire, the corresponding warning will appear.

Configuring Server Storages (Admin Only)
Nx Witness provides an easy and flexible storage management policy. Each Server can use unlimited number of local and network Storages. If more than one Storage is used, Server will automatically balance the space consumption. The more free space the storage has, the higher the usage intensity will be.
Storage is considered to be a separate hard disk partition. If a partition has more than 100 Gb of free space, Nx Witness uses it automatically.
Additionally it is possible to add network storages.
To configure Server Storages:
.
2. Go to Storages:
As displayed above, the computer has 2 partitions and only disk D is used for storage because disk C has less than 100 Gb of free space.
3. To select Storage to be used check In Use flag

Configuring Multi-Server Environment (Admin Only)
Nx Witness is a very scalable solution and it allows many Servers to work together in a single System.
This section describes how to manage multi-server environment to maintain maximum system reliability and performance:
·
Understanding Multi-Server Architecture and Basics
·
·
·
Configuring Routing within Multi-Server Environment
·
Configuring Time Synchronization within Multi-Server Environment .
Understanding Multi-Server Architecture and Basics
Nx Witness implements the unique hive architecture that enables high redundancy , performance and provides almost unlimited scalability. Servers can be located in a local network, behind NAT or even in a different location – they will act as a single cluster allowing users to view cameras and control the whole system from a single workstation.
If several Servers are working together they should somehow connect to each other. To do so servers have the unique identifier - System Name, that allows server to group together. If Server discovers another Server with the identical System Name in a local network, they merges automatically. If System
names are different, Server will display other one in Resource Tree
under Other Systems.
If Servers are in different subnets, it is necessary to specify other Server's IP to make them merge in separate networks (behind NAT or over the Internet).
When Servers are merged, they are constantly synchronizing all data between each other so it doesn't matter what server Client is connected to. If a video is requested from a remote Server, the one Client is connected to will be proxying the video traffic. Licenses are combined as well: if 4 licenses were activated on server 1 and 10 – on Server 2, System will have 14 Licenses total after the servers are merged.
Thus, the only thing Administrator should do to merge systems, is to assign the same system names to all
Servers. Opposite, to split Systems Administrator needs to assign different system names.
Nx Witness User Manual

Joining and Splitting Servers
There is several ways to join and split servers:
·
Join Server from Different System to Current-One
·
Split Server to Different System
·
Merge all Servers to Another System .
Join Server from Different System to Current-One
This action can be useful if there is a single Server in a different System in local network. To join such server to the current system it is possible to use Nx Witness Client or
Client:
1. Expand Other Systems under
and locate the desired system
2. Expand desired system and locate Server to connect to the current System.
and choose Merge to Currently Connected System...
4. Enter the admin password of the other System.
Web Interface:
1. Log in to web-interface of Server that should be connected to the current System
2. Change System Name to the desired value and click Save.
After some time the desired Server will be joined.
If it is necessary to connect several Servers in a different System to the current-one, this method may not be an option. Also, this method won't work if the server that should be joined, is outside local network.
Merge all Servers to Another System
should be used for these purposes.
Split Server to Different System
This action can be useful if it is necessary to isolate Server from current System. This is pretty rare operation.
To split Server to another System use Server's Web Interface :
1. Log in to web-interface of Server that should be split off the current System
2. Change System Name to the any other value and click Save.
34 Nx Witness User Manual
Configuring Multi-Server Environment (Admin Only)
Merge all Servers to Another System
This operation can be useful if there is System A that contains several Servers and all of them should be joined to another System B. Also this method should be used to join remote server(s) to a current system.
Note: If Licenses have been previously activated on this server, they will be gone from the current
System.
To split Server from System use Web:
1. Launch Nx Witness Client and connect to any Server in system A.
2. Right-click on System, invoke
and choose Merge Systems.
3. Enter Server URL (any server of System B or remote Server). To find Systems in local network use drop-down menu. For Remote Server type
http://<ip>:<port>
:
·
<ip>
– IP address of Server (the current computer should be able to connect to this Server)
·
<port>
– network port of Server (default
7001
).
4. Enter Password to System B (or to remote Server) and click Find System.
5. Select the new System Name (System A or System B).
·
System A – System B will be merged to System A
·
System B – System A will be merged to System B
6. Click Merge with <System Name>.

Configuring Failover
Nx Witness can automatically manage failover in multi-server environment. If Server goes down, all cameras are transferred to other Servers and Client is being reconnected to other Servers as well. The archive playback will remain seamless, however this may be a 30 seconds gap in recording during the transfer.
Failover should be configured on backup servers. For instance if System contains Server A and Server B it should configure Server A to take over Cameras from Server B and vice versa.
IMPORTANT. To be able to do failover, both server should be able to access cameras.
To configure Failover:
1. Find Server B in
and choose Server Settings.
2. Click Enable Failover.
3. Enter the number of Cameras the server can handle.
4. Click OK. Now If Server A goes down, all cameras will be transferred to Server B.
5. To make Server A handle the cameras from Server B, make the same on Server A.
IMPORTANT. To be able to do failover, Server should be able to handle double amount of cameras.

Configuring Routing within Multi-Server Environment
Nx Witness provides built-in automatic routing mechanism that enables users to seamlessly work with the large sites as a single cluster. However there may be custom network configurations that may require custom routing settings. For instance, Servers may have several IP addresses (Public and Private) and it may be necessary to allow or restrict traffic flow for some of them.
Initially Nx Witness tries to discover all available IP addresses of servers (including Public ones). However it is not possible in some network environments.
To setup routing open Main Menu
–> System Administration (CTRL+ALT+A) and go to Routing Management tab.
On the left all Servers are displayed. If click on Server all available interfaces are displayed in the right hand side.
·
To add an address manually click "+" and add URL like
http://<ip>:<port>
:
·
<ip>
– the desired IP address of Server (i.e. Public IP)
·
<port>
– network port Server is listening on (default
7001
).
·
To allow/deny traffic to go through the specific network interface click In Use to set/release checkbox.
For instance, Server can have Public IP address and is connected to the Internet via 100 Mbit network and local NIC with local IP address (1Gbit). If it is not necessary to provide public access to this server it may be useful to restrict traffic flow through Public IP.
Configuring Time Synchronization within Multi-Server
Environment
Nx Witness provides built-in time synchronization mechanism. However this mechanism synchronizes the time with the Internet and it no Internet connection available, it may be necessary to configure time settings manually. Even in this case Nx Witness tries to synchronize time across servers. Manual settings are needed if it ns necessary to specify Master Time Server: the one all other Servers will synchronize to.
To do so open
–> System Administration (CTRL+ALT+A) and go to Time Synchronization tab.
Initially Nx Witness tries to discover all available IP addresses of servers (including Public ones). However it is not possible in some network environments.
To go to routing setup open
–> System Administration (CTRL+ALT+A) and go to Routing
Management tab.
The table shows all Servers that are currently online, current time and offset from Internet time or master server time.
To specify Master Time Server tick it in the table and click OK.

·
Adding Cameras and Encoders Manually (Admin Only)
·
Adding RTSP or HTTP Streams as Cameras (Admin Only) .
Discovering Cameras Automatically
Nx Witness provides a powerful and easy-to-use mechanism for automatic camera discovery. It is required that a camera should be accessible via Broadcast.
As soon as Server is started and connected to Server, it automatically performs camera discovery in its network. Once a camera is discovered, its parameters will be displayed in
automatically.
If a camera does not transmit media data, it is marked as Offline.
If Server is offline, all Cameras the server is hosting are switched to the offline status automatically.
Once Camera is discovered, <%PRODUCT NAME%> tries to configure the following settings on Camera: the best possible image settings for the main video stream (best possible resolution and FPS) and optimal ones for the secondary stream (240p to 320p, 2 to 7 FPS). To disable this feature, see "

Setting up Recording Schedule
To record Camera, Recording Schedule must be set up first.
Note: It is possible to configure Cameras for Administrators and Viewers with an appropriate
permission level.
Note: To record one camera, License is required. See “
Obtaining and Activating Nx Witness Licenses
”. Even if recording is not performed immediately, the License will still be considered as
used.
The recording schedule specifies the following recording parameters:
·
Recording Type:
·
Record Always
·
Motion Only – records only when motion occurs. Motion recording may require for the camera to support motion detection.
·
Motion + Lo-Res Always – by default, a camera is set to record at low resolution unless motion occurs, at which point it switches recording to high resolution automatically. High resolution recording requires dual streaming (if supported by camera). See "
Dual Stream Recording Specifics
·
FPS
·
Quality
Note: FPS and Quality recording settings will affect live stream viewing as well. For example, if 1 FPS and Low Quality are set in the recording schedule, Nx Witness will stream live as per selected settings even if the camera is capable of more. If recording is not set, Nx Witness will stream live at Maximum FPS and Quality.
Those settings are applied to Recording Schedule. See " Modifying Recording Schedule " for details.
Nx Witness User Manual

Dual Stream Recording Specifics (RADASS)
Some Recording Parameters may need Motion to be supported by the Camera. Motion + Low Quality
Always recording requires Dual-Streaming to be supported by Camera.
If Dual-Streaming is supported, the second stream settings are set automatically based on the main recording settings:
·
2 to 7 FPS
·
320p to 480p
Not only is the second stream used for recording, it is also used for Software Motion Detection and
bandwidth and CPU saving during playback. See "

Configuring Maximum and Minimum Recording Time for Camera
Some governmental regulations require the footage to be stored for a specific amount of time. Nx
Witness supports the ability to set up maximum and minimum recording amount.
IMPORTANT. Be careful with minimum amount. These settings do not guarantee this to be kept, they just set the priority. So, in case of insufficient space Nx Witness will delete the records on cameras that do not have minimum amount of footage. However if there is no space to store such amount of data, no
other cameras will be recorded.

Setting up Motion Mask and Motion Sensitivity
In order to detect motion more properly and accurately, Nx Witness provides a powerful and flexible
Motion Detection configuration. For example, if a camera is pointed at a parking lot, motion mask can be set on all the surrounding areas that are not targeted for recording. In this case, any motion appearing in the areas surrounding the main target area, will not trigger motion detection and recording.
IMPORTANT. This particular feature in Nx Witness works only if the selected camera supports Motion
Detection.
The following Motion Detection types are supported:
·
Hardware Motion Detection – implemented on Cameras directly. In this case only motion mask can be configured. To configure additional parameters it may be necessary to go to Camera Settings web
page (see " Configuring Proprietary Camera Parameters "). For Arecont Vision this mode is set
automatically.
·
Software Motion Detection is performed on Server . It consumes more resources, though it provides better and more flexible motion detection. In this case, it is possible to set up unlimited number of motion regions and adjust its sensitivity. Software Motion Detection requires Dual-Streaming supported by Camera. If supported, Software Motion Detection is set automatically (excluding
Arecont Vision cameras). If primary stream is 480p or less, it can be used for Software Motion
Detection as well.

Adjusting Secondary Stream Quality
Nx Witness's architecture provides significant CPU and network bandwidth savings by acquiring multiple streams from a single camera: High Resolution (regular) and Low Resolution (approximately x10 less bandwidth). The second stream is always decoded by Server and is used for the following:
·
Software Motion Detection
·
CPU and Bandwidth Saving during Playback (RADASS)
The quality of the second stream is set automatically, however, it is possible for User to adjust the quality of the stream.
IMPORTANT. Higher quality of the second stream provides for a much better look and feel (especially on larger monitors), but can significantly increase CPU load on Server . It is not recommended to change these settings.
To adjust the quality of the second stream:
and go to Expert.
2. Check I have read the manual and understand the risks.
3. Adjust Secondary stream quality.
4. Click Apply or OK when finished. To discard changes, click Cancel.
Note: If Camera does not support dual-streaming, the above settings are unavailable.

Disabling Recording of Primary/Secondary Stream
For some reasons it may be necessary to disable recording of primary or secondary streams. For instance:
·
Primary – to save space. Instead it is recommended to set "Motion + LQ" recording type
·
Secondary – if secondary stream's bitrate is too high. In this case Nx Witness server will still do software motion detection (by decoding asecondary stream for this purpose), but won't record it.
To disable recording of primary or secondary streams
and go to Expert.
2. Check I have read the manual and understand the risks.
3. Tick Do not archive primary stream or Do not archive primary stream.
Setting Up Camera Transport Protocol
Some cameras stream data in a different way. Usually 2 protocols are used for streaming: UDP (faster, but less reliable) and TCP (more reliable, but slower). Nx Witness tries to determine the best protocol for the camera. However, sometimes camera may have issues when streaming via the chosen protocol. In this case setting the protocol manually may help.
To do so:

Swapping Cameras between Servers (Admin Only)
If too many cameras are used on the network, it may be helpful to set up an additional server for load balancing and redundancy purposes. If several servers are set up on the same network, it is possible to perform manual load-balancing.
This is how camera swapping works:
1. Step 1: Server is connected to Server and starts discovering Cameras. As soon as Cameras are discovered, they will appear in the Client.
2. Step 2: Server is connected to Server and starts discovering Cameras. As soon Cameras are discovered, their MAC Addresses are checked. If Camera is registered on Server , it will not appear in the Client and a “Disabled” flag is set in the database.
3. Once Camera is moved to another Server , it becomes Enabled in the second Server and automatically disables itself in the first one.
IMPORTANT. When moving Camera from one Server to another, recording will be restarted automatically (with predefined parameters). Also, Archive is seamlessly combined from all servers.
To move camera(s) from one server to another:
1. Hold Ctrl or Shift to select the desired cameras in
2. Drag and drop the selected cameras to the desired server

CPU and Bandwidth Saving during Playback (RADASS)
Nx Witness's architectures provides significant CPU and network bandwidth savings by acquiring multiple streams from a single camera: High Resolution (regular) and Low Resolution (approximately 10 times less bandwidth). If there is not enough bandwidth between Client and Server to display the High Resolution stream while viewing a camera, then the camera is automatically switched to Low Resolution mode.
In case of insufficient CPU, a user may experience difficulties with displaying too many videos simultaneously (examples: running over 20 full high resolution videos at the same time, fast forwarding multiple full high definition videos at the x16 speed, etc.). In this instance, cameras are switched to a Low
Resolution stream. As a result, CPU will yield a much smoother playback.
Additionally, it is possible to choose resolution manually. To do so, Right-Click on Scene's empty space and choose Change Resolution... The changes are applied once to the entire Layout and will be reverted back to Auto whenever a user re-opens Layout.
Note: this feature requires support of camera dual-streaming.

Navigating through Several Cameras Synchronously
Nx Witness provides a powerful engine that enables users to navigate through multiple cameras: if several Cameras are displaying at the same time, they can be synchronized.
If User performs search, fast forward, rewind or search by frame – each camera will be synchronized.
However, recording may be set up differently. If no recording took place over a certain period of time, NO DATA will appear on the camera view.
Recorded fragments are displayed on the Time Line in two rows:
·
The upper row displays fragments for Camera selected on Scene
·
The lower row – for all Cameras displayed on Scene
It is possible to disable Synchronization (press SYNC button). If no Item is selected, the selection will move to the previously selected item, which will become the only item affected by playback controls
(seek, speed etc).
Thus, if Synchronization is disabled, it is possible to seek each Camera in a different position. In this case
Time Line displays positions for all Cameras played back (see blue markers on the picture):
If User selects Camera on Scene and enables Synchronization again, all other cameras will get synchronized with the selected Camera (Position and Speed will be synchronized).

Restoring Broken Archive
Restoring Broken Archive
Nx Witness uses a specific directory on each network drive. However, sometimes archive is moved for various reasons (ex, a hard drive was replaced, hard drive's letter was changed. etc), possibly resulting in a complete removal of archive from the system.
Nx Witness can easily restore the lost archive. To perform archive restoration:
.
2. Click on Rebuild Archive Index.
3. The process can take a long time. Click Yes to proceed.
Restoration can be canceled in any moment.
If the window is closed, the restoration will continue running in the background.
The system can continue recording while the archive is being restored.

Providing Remote Access
The best possible way to help investigate an issue is to provide remote access via one of the following applications:
·
Team Viewer ( http://www.teamviewer.com
)
·
Citrix GoTo Meeting ( https://www.citrix.com/products/gotomeeting/overview.html
)
·
VNC: RealVNC ( https://www.realvnc.com/ ), TightVNC ( http://www.tightvnc.com/ ), UltraVNC ( http:// www.uvnc.com/ )
·
RDP (Windows Remote Desktop). Requires Public IP.
For Linux Mac it is possible to open SSH access. Requires Public IP.
Finally Public IP is necessary for the following investigations:
·
Ability to connect remotely to the system and debug issue on the client side (Server should be accessible via Internet)
·
Camera issues investigations. For this purpose Camera should be accessible via Internet by Public IP.
Recording Issue
If it is not possible to provide remote access for security reasons, a supporting video clip can help understand and investigate the issue. To create a video clip:
1. Set up Screen Recording: select desired screen and microphone settings (see " Setting up Screen
2. Record a narrated (preferred) video explaining the issue (see " Performing Screen Recording ").
3. Attach the video to the support ticket.
