CVG Installation Guide
Introduction
This guide explains how to set up the hardware components of SerVision’s standard CVG security system. The
standard CVG belongs to SerVision’s line of embedded Video Gateway units. These units provide state-of-the-art
security functionality, including live video streaming, video recording and playback, motion detection, sensor
management, real-time event notification, and device activation. All of these features can be accessed remotely via
PC, PDA, or cellular telephone. The standard CVG is a basic unit that is optimized for deployment in buildings in
which high-speed internet access is available through a cable-based local network (LAN).
Once the CVG has been installed as explained in this guide, it must be configured. Configuration is performed by
connecting to the CVG unit using a PC that is on the same network as the unit (or connected to the unit directly
using a LAN cross cable) and opening the unit’s configuration utility in a browser. For additional information about
configuring your CVG, please refer to the Embedded Video Gateway System Guide.
Client software is used for accessing the CVG unit remotely in order to view video and events and control the
system in various ways. SerVision offers client software for PCs and for certain cellular telephone and PDA
models. Full instructions for the use of the client applications are available in separate manuals, which can be
downloaded at http://www.servision.net.

Supplying Power to Devices Connected to the Unit
The CVG can supply power directly to cameras and other devices via the 12VDC Power Out connector on the rear
panel of the unit. However, only a limited amount of power can be supplied by the CVG in this way. If the devices
connected to the 12VDC Power Out connector draw too much power, the unit may overheat or otherwise
malfunction. Therefore, it is best to provide independent power supplies for devices connected to the unit whenever
possible by connecting them directly to a wall outlet.
The unit can supply a maximum of 250 mA (3W at 12V) of power through the 12VDC Power Out connector.
Typically, this means it can power at most one camera. Nonetheless, you must consult the device documentation to
ascertain the actual power usage of each device you want to connect to the CVG unit. For example, if a camera uses
150 mA and a sensor uses 50 mA, the total power usage of the two devices is 200 mA. Since the CVG can supply a
maximum of 250 mA, this means that 50 mA are available for other devices when these two devices are connected
to the 12VDC Power Out connector on the CVG.
NOTE:
It is, of course, possible to connect some devices to the 12VDC Power Out connector on the CVG and
others directly to a power source – as long as the total power consumption for the devices connected to
the 12VDC Power Out connector does not exceed 250 mA.

CVG Installation Guide
Connecting Devices to the CVG
This section explains how to connect devices such as a camera or a sensor to the CVG unit.
Connecting Cameras
Up to two cameras can be connected to the CVG. If the cameras have PTZ controls for remote aiming and zooming,
and the PTZ protocol they use is supported, the control cables can also be connected to the unit.
Any PAL or NTSC video camera with a composite video output can be connected to the unit. A cable with a
composite video connector on one end, and a male BNC connector on the other, should be used to connect each
camera to the CVG.
NOTE:
A cable with a male RCA connector can be connected to a female BNC connector by using an RCAto-BNC adaptor.
Figure 3: RCA-to-BNC adaptor
Cameras that are connected to the CVG can receive their power from the CVG unit through the 12VDC Power Out
connector on the rear panel of the unit. However, bear in mind that the unit can supply a maximum of 250 mA (3W)
of power through this connector. Typically, this is only enough power for one camera. If the devices connected to
the unit require more than this amount of power, you must power some or all of them independently by connecting
them directly to a power source, as explained under Supplying Power to Devices Connected to the Unit, page 8.

 To connect a camera:
1. Install the camera in its desired location.
2. Connect the output of the camera to one of the Video In connectors on the unit.
3. Connect the camera's power connector to a power source.
Connecting a PTZ Controller
If a camera has remote PTZ control features (pan, tilt, zoom, and/or focus), and uses a supported PTZ protocol, you
can connect the control cable to the unit. Both RS232 and RS485 PTZ connection types are supported. Consult the
camera documentation for information about which connection type to use.
NOTE:
If you are connecting sensors to the unit using an ADAM module or you are using the RS232/485
connector to connect a touchscreen CCTV monitor to the unit, you cannot connect any RS232 PTZ
controllers. For additional information, see Connecting Sensors Using an ADAM Module, page 12;
Connecting a CCTV Monitor, page 18.
If you want to connect the PTZ controllers of two cameras to the unit, only one of the controllers can use an RS232
connector – the other must use an RS485 connector. PTZ controllers for more than one RS232 camera cannot be
connected to the unit simultaneously.
Connecting Devices to the CVG
9
SerVision
CVG Installation Guide
If you connect two RS485 PTZ camera controllers, they should be daisy-chained to the RS232/485 connector, as
described below. In this case, each camera in the chain must be given a different ID number. Please refer to your
camera's documentation for information about configuring its ID number. In addition, note that you can only create
an RS485 daisy chain if both cameras use the same PTZ protocol. Attempting to connect cameras that use different
protocols will prevent both of the cameras from working properly.

 To connect an RS232 PTZ controller:
The RS232 controller cable should end with a female 9-pin RS232 connector.
 If you are only connecting the RS232 PTZ controller to the unit, and are not connecting any RS485 PTZ
controllers, plug the 9-pin RS232 connector directly into the RS232/485 connector on the side panel of the
unit.
 If you are also connecting one or two RS485 PTZ controllers to the unit, plug the 9-pin RS232 connector into
the RS232/485 adapter supplied with the unit.

 To connect an RS485 PTZ controller:
Each RS485 controller cable should end with two wires.
1. Use a wire connector to connect the wires to the RS485 connection wires of the adapter. Be sure to match the
positive (+) wire of the controller cable to the positive (+ red) wire of the adapter, and the negative (-) wire of
the controller cable to the negative (- grey) wire of the adapter (see figure 4).

CVG Installation Guide
Connecting Sensors
Sensors are devices that detect events such as a door being opened or a light being turned on. A dry-contact input
sensor can be connected directly to the unit. Alternatively, the sensor connector on the unit can be used to connect a
switch to change the active outline or the display on a connected CCTV monitor.
In addition, if you wish, you can connect either an ADAM Data Acquisition Module or an IA-3126-2 relay board to
the unit. Either of these devices makes it possible to connect up to 16 additional sensors to the unit.
Connecting a Sensor Directly to the Unit
The unit has one sensor connector (In1). You can use this connector to connect a dry-contact input sensor to the
unit. Alternatively, In1 can be used to connect a switch for one of the following purposes:
 Outline switch: If you are defining more than one outline (alternate sets of recording and event-handling
settings), you can connect a toggle (on-off) switch to In1 instead of a sensor. The switch can then be used to
change the active outline. For additional information, please refer to the Embedded Video Gateway System
Guide.
Note: Some alarm panels can also be connected to In1. When they are, they can function as automatic outline
toggle switches. For additional information, please consult the alarm panel vendor.
 CCTV-monitor display controller: If a CCTV monitor will be connected to the unit, you can connect a
push-button switch to In1 instead of a sensor. The button can then be used to change the display on the
monitor. For additional information, please refer to the Embedded Video Gateway System Guide.
NOTE:
It is possible to configure the CVG to use a single switch as both an outline switch and a CCTVmonitor controller, but this is not generally advisable, because it is unlikely that you will find it
convenient to have the outline switched every time the CCTV display changes, and vice-versa.

 To connect a sensor or switch directly to the unit:
1. Install the sensor or switch in its desired location in accordance with the manufacturer's instructions.
Note: If the sensor requires an external power supply, you may be able to connect it to the 12VDC Power Out
connector on the rear panel of the unit. However, bear in mind that the unit can supply a maximum of 250 mA
(3W) of power. If the devices connected to the unit require more than this amount of power, you must power
some or all of them independently (see Supplying Power to Devices Connected to the Unit, page 8).
2. Connect the two wire contacts of the sensor or switch to the In1 connector on the rear panel of the CVG, as
illustrated in figure 6. Insert the wires into the connectors and tighten the screws below each connector to hold
the wires in place. It does not matter which wire you connect to each contact.

Connecting Sensors Using an ADAM Module
If you want to connect additional dry sensors to the CVG, you can do so by connecting an ADAM Data Acquisition
Module to the unit. Up to 16 additional dry sensors can then be connected to the unit through the ADAM module.
NOTE:
Alternatively, you can connect additional sensors using an IA-3126-2 relay board, as explained
Connecting Sensors and Activators Using an IA Relay Board, page 16.
To connect sensors using an ADAM module, you will need the following items:
 ADAM-4051 Data Acquisition Module (available from SerVision)
 ADAM-4520 isolated RS232->RS422/RS485 converter (available from SerVision)
 Flat ribbon cable with D-type 9-pin female connector on one end and a D-type 9-pin male connector on the
other end
 Wire to connect the ADAM module to the ADAM converter – red, black, yellow, and green
 Wire and an electrical plug (optional) to connect the ADAM module to a power source (either a power supply
from the unit or an independent connection)
Figure 7: ADAM-4051 module
NOTE:
Figure 8: ADAM-4520 isolated converter
The instructions below explain how to connect sensors to the CVG using the ADAM module and
converter described above. For additional information about connecting and configuring the ADAM
module and converter, please refer to the manufacturer's documentation, or contact your vendor.

 To connect sensors using an ADAM module:
1. Install the sensors in their desired locations in accordance with the manufacturer's instructions.
2. Connect the wire contacts of each of the sensors to the terminal blocks of the ADAM-4051 module as follows:
 Connect all of the negative (-) wires of all of the sensors to one of the ground (D GND) connectors on the
ADAM module. If the wires cannot all be inserted into the connector, use a wire connector to connect
them together, and then connect the wire connector to the ground (D GND) connector on the ADAM
module.
 Connect each of the positive (+) sensor wires to one of the numbered connectors (D1 0 through D1 15) in
the terminal blocks of the module.

Connecting Activators
Activators are external devices such as alarms and lights that can be turned on by the system in response to an
event. Essentially, the unit functions as an on/off switch for the device. The unit activates the activator by closing
the circuit of its power supply. One activator can be connected directly to the unit. In addition, if you wish, you can
connect an IA-3126-2 relay board to the unit. This makes it possible to connect up to 16 additional activators to the
unit (see Connecting Sensors and Activators Using an IA Relay Board, page 16).
In addition to the activator itself, you will need 16 AWG red and black cables to connect an activator to the unit.

 To connect an activator directly to the unit:
1. Install the activator in its desired location in accordance with the manufacturer's instructions.
Note: If the activator requires an external power supply, you may be able to connect it to the 12VDC Power
Out connector on the rear panel of the unit. However, bear in mind that the unit can supply a maximum of 250
mA of power. If the devices connected to the unit require more than this amount of power, you must power
some or all of them independently. For additional information, see Supplying Power to Devices Connected to
the Unit, page 8.
2. Connect the two contacts of the activator to the Out1 connector on the CVG, as illustrated in figure 12. It does

If you want to connect additional dry sensors and/or one activator to the CVG, you can do so by connecting an
Intelligent Appliance IA 3126-2 relay board to the unit. Up to 16 additional dry sensors and 16 additional activators
can then be connected to the unit through the relay board. Sensor and activator events from devices connected to an
IA relay board can be seen in SerVision client applications and activators can be turned on and off via these
applications. However, the sensors and activators cannot be configured using the CVG’s configuration utility.
NOTE:
Alternatively, you can connect additional sensors using an ADAM module, as explained under
Connecting Sensors Using an ADAM Module, page 12. Sensors that are connected through an ADAM
module can be configured using the CVG’s configuration utility.

the CVG. It is primarily useful if you want to view video when the user is near the unit. For example, if the CVG is
set up in a grocery store, and you sit at the check-out counter, you can use a CCTV monitor to keep tabs on parts of
the store that you cannot see from your seat.
The following types of monitors can be used:
 Surveillance monitors: Monitors that are designed to be plugged directly into surveillance cameras.
 Entertainment monitors: Monitors that are intended to be plugged into portable DVD players in vehicles.
 Standard television sets with AV connectors
When choosing a monitor to connect to the unit, ensure the monitor supports the video format used by the cameras
(NTSC or PAL). Some SECAM monitors will also work when the PAL video format is used.
If you choose a monitor with touchscreen support, you can use the monitor to view recorded video as well as live
video. For information about recommended types of touchscreen monitors, please consult your vendor.
NOTE:
If you are connecting an RS232 PTZ controller to the unit, you cannot use touchscreen functionality
because the RS232 serial port is not available. For additional information, see Connecting a PTZ
Controller, page 9.
To connect the monitor to the CVG, you will need a cable with the following connectors:

CVG Installation Guide
 An appropriate connector (BNC or RCA) for the Video In connector of the monitor. (Consult the monitor
documentation or your vendor to find out which kind of connector is required for the particular monitor you
are using.)
 A BNC male connector to connect to the TV Out connector of the CVG. (A cable with an RCA connector can
be used by attaching a BNC-to-RCA adaptor to the connector. See figure 7, page 9.)
To connect the output of a touchscreen to the unit, you will need a cable with the following connectors:
 An appropriate connector to connect to the touch output connector on the monitor
 A female 9-pin RS232 connector to connect to the CVG’s RS232/485 connector.
An appropriate cable should be supplied with the monitor.

 To connect a CCTV monitor:
1. Install the monitor in its desired location.
2. Connect the Video In connector of the monitor to the TV Out connector of the CVG, using a cable with an
appropriate connector (BNC or RCA) for the Video In connector of the monitor on one end, and a BNC male
connector on the other end.
Note: If you are using a standard television set as a monitor, use the television’s AV connector as the Video
Input connector.
3. If the monitor is touch-sensitive, connect the touch output to the RS232/485 connector as follows:
 If you are not connecting any RS485 PTZ controllers to the unit, connect the RS232 connector of the
touch output cable directly into the RS232/485 connector.
 If you are also connecting one or more RS485 PTZ controllers to the unit, connect the RS232 connector
of the touch output cable to the RS232 connector of the RS232/485 adapter supplied with the unit (see
figure 16 below). Connect the PTZ controllers to the adaptor as explained under Connecting a PTZ
Controller, page 9. Then plug the adaptor into the RS232/485 connector on the unit.

about how to calibrate the monitor, please refer to the monitor’s documentation.
Connecting a Switch
If you wish, you can connect a switch to the unit to change the display on the monitor. The switch must be
connected to the In1 connector. For additional information, see Connecting Sensors, page 11, and refer to the
Embedded Video Gateway System Guide.

Connecting Multiple Monitors
If you wish, you can connect multiple CCTV monitors to the CVG. For example, you may wish to have one
monitor beside the driver’s seat and another beside the conductor’s seat.
To connect multiple monitors, you must use video splitters to split the connection. Bear in mind, however, that the
image quality in each of the monitors will be slightly degraded. To correct this problem, you can use a video
amplifier (booster) for each monitor. To ensure you have the correct equipment, consult a video equipment supplier.

Connecting the CVG to a Network
The standard CVG should be connected to a local network using a network cable. Once connected, it can be
accessed either from a PC on the same LAN network or via the internet through the LAN’s gateway (router).

 To connect the CVG unit to a LAN:
 Connect the Ethernet Out connector on the CVG unit to a LAN connection point (a hub, wall socket, or any
other connection point) using the supplied Ethernet cable (see The CVG Package, page 4).

Connecting the CVG to a Power Source
The standard CVG must be connected to an electrical outlet using the supplied power-supply cable. Once it is
connected, the unit starts up automatically. During the start-up process, the Power LED on the top of the unit
flashes at various intervals. When the start-up process is completed successfully, the Power LED should display as
a solid color and blink momentarily every second. (Depending on the configuration settings, it should either be solid
orange and then blink green or solid green and then blink orange.)
Power LED
Figure 17: Power LED
NOTE:
When the start-up process is completed, if the Power LED does not flash – it displays as a solid green
or orange all the time – the start-up process was not successful. In this case, disconnect the unit from
the power supply and then reconnect it.
WARNING: Only the power supply cable that came with the unit should be used. Use of a power supply other
then the one provided in the package may cause irreparable damage to the unit. In particular, do not
use the power supply cable from an HVG 200 unit, because it will not supply sufficient power to
the unit. Furthermore, and most important, never use the CVG power supply cable with an
HVG 200, because this will ruin the HVG 200.

 To connect the standard CVG to a power source:
 Connect the Power connector on the rear of the CVG unit to a standard wall socket using the supplied power
supply cable (see The CVG Package, page 4). The unit starts up.
