CVG-M Installation Guide
Introduction
This guide explains how to set up the hardware components of SerVision’s CVG-M security system. The CVG-M
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 CVG-M is optimized for deployment in vehicles and other mobile platforms or remote locations in which a
LAN connection is not available. It has built-in support for cable-based and cellular networking, and contains an
internal GPS receiver that makes it possible to track its location and route. It can also be integrated with some fleetmanagement systems (such as the Galooli system; see http://www.galooli.com/solutions/galooli-fleet/).
Once the CVG-M has been installed as explained in this guide, it must be configured. Configuration is performed
by connecting to the CVG-M 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-M, please refer to the Embedded Video Gateway System Guide.
Client software is used for accessing the CVG-M 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.

Note: Normally supplied only
with demo units (see note
below).
NOTE:
The power-supply cable, the power-connector cable, and the power cord with cigarette-lighter
connector are not required for operation of the CVG-M in a vehicle, because the unit is hard-wired to
the vehicle battery when it is installed.
Typically, the CVG-M unit is configured in an office setting before it is installed, and for that the
power-supply and power-connector cables are used. Since only a small number of units are configured
at one time, power-supply and power-connector cables are not required for every unit of a large order.
After configuration, the units normally only need power-supply and power-connector cables if they
malfunction and are removed from the vehicles in which they are installed in order to perform troubleshooting procedures on them in the office.
The power cord, which has a cigarette-lighter connector, is not required for normal installations; it is
useful primarily for testing of demo units, which are not installed in the vehicles or hardwired to the
battery.
In keeping with SerVision’s “green” policy of preventing unnecessary waste, only a limited number of
power-supply and power-connector cables are supplied with each order. Please retain the cables you
receive for use with all of the units you purchase. Similarly, power cords with cigarette-lighter
connectors are only supplied with demo units. If you require more of any of these items than are
normally supplied, please consult yours sales representative.

1. Insert the SIM card into the SIM-card slot; see Inserting the SIM Card, page 26.
2. Place the CVG-M unit in its desired location; see Selecting a Location for the Unit, page 7.
Note: If you are installing the CVG-M in an insulated container (see Preventing Overheating, page 8), you
must install the container in the vehicle and the CVG-M in the container.
3. Install the video cameras in their desired locations.
4. Install a CCTV monitor in its desired location (optional).
5. Install either a dry sensor, a toggle switch (for outline switching), or a push-button switch (for changing the
display on a connected CCTV monitor) in its desired location (optional); see Connecting Sensors, page 16.
6. Install an alarm or other activator in its desired location (optional); see Connecting an Activator, page 20.
7. If you are using either an ADAM module to connect additional sensors to the CVG-M, install the sensors in
their desired locations (optional); see Connecting Sensors, page 16.
8. If you are using an IA relay board to connect additional sensors or activators to the CVG-M, install them in
their desired locations (optional); see Connecting Sensors and Activators Using an IA Relay Board, page 21.
9. Connect the cameras and other devices to the CVG-M, as required; see Connecting Devices to the CVG-M,
page 14.
10. Connect the unit to a LAN using an Ethernet cable (optional); see Connecting the CVG-M to a Network,
page 26.
11. Install the GPS antenna in an appropriate location in the vehicle and connect it to the unit (optional); see
Connecting the GPS Antenna, page 28.
12. Connect the cameras and other devices to the vehicle battery, as required; see Supplying Power to Devices
Connected to the Unit, page 11.
13. Connect the CVG-M unit to a power source; see Connecting the CVG-M to a Power Source, page 29.
NOTE:
If the unit is being installed in a vehicle, the devices connected to it, and the cables used to connect
them, must all be securely fastened to the vehicle to ensure they do not become detached from their
locations when the vehicle is in motion.
NOTE:
Installing the unit and its peripheral equipment in a vehicle is a complex process. It is highly
recommended that it be performed by a trained specialist in vehicle installations.
Selecting a Location for the Unit
The CVG-M unit should be placed on a flat surface such as a shelf. (It is not designed for mounting directly on a
wall.) If it is being installed in a vehicle, the unit should be installed in a cool and ventilated location, protected
from direct sunlight and water (including liquids used to clean the inside of the vehicle), and as far away from
humidity as possible. It should not be installed in a closed location, such as the in the trunk or dashboard, or under
Installing the CVG-M System

the paneling, of a car. Ensure the unit has at least 20 centimeters (eight inches) of space above it and on all sides for
ventilation.
When choosing a location for the CVG-M, bear in mind that the unit must be connected to a power source and a
LAN or a PC, and that other devices (cameras, sensor, etc.) must be connected both to it and to power sources. If
the unit will be installed in a vehicle, it must be connected to the vehicle battery and ignition (if required), and the
cellular and GPS antennas must be located relatively high up and in exposed locations (see Connecting the Cellular
Antenna, page 26; Connecting the GPS Antenna, page 28) Choose a location in which these connections are
feasible.
Preventing Overheating
CVG-M units should be installed in the passenger compartment in a location that is cooled by the vehicle's airconditioning when the air conditioner is on. Ideally, the units should be installed in insulated plastic containers with
built-in fans. Each container should have two fans, one to draw cool air into the container and the other to push hot
air out of it. Containers of this type are available for purchase from vehicle-accessory suppliers. The containers
should be installed in the vehicles in accessible locations, with as much ventilation as possible. The ends of cellular
and GPS antennas should be placed outside the containers. If you plan to remove the micro-SD card from the unit
without removing the unit from the container, make sure to allow enough space at the front of the unit to do so (see
Appendix 1: Removing the MicroSD Card, page 34).
NOTE:
Do not install the unit in a metal container; metal interferes with wireless reception.

Supplying Power to Devices Connected to the Unit
Cameras and most other peripherals connected to the CVG-M unit usually require independent power supplies.
These devices should be connected directly to the vehicle battery (or some other power source).
NOTE:
In some cases, it may be possible to provide power to certain devices through the 12VDC Power Out
connector on the rear panel of the CVG-M. This option is not appropriate for supplying power to
cameras. For additional information, see Using the 12VDC Power Out Connector, page 36.
Turning the Device Power On and Off with the Ignition
When the CVG-M is installed in a vehicle, it is normally configured to shut down whenever the vehicle ignition is
turned off. All devices that draw their power through the 12VDC Power Out connector on the CVG-M are also
turned off when the CVG-M shuts down, because they do not receive any power from the unit. If you want devices
that are directly connected to the vehicle battery to also shut down when the vehicle ignition is off, you should route
the power supply through the activator connector (Out1) on the CVG-M unit, as illustrated below.
Installing the CVG-M System
11
SerVision
CVG-M Installation Guide
Figure 7: Connecting cameras to the power supply through the Activator connector
Transforming the Supplied Voltage to 12V
When the power supply for one or more devices is routed from the vehicle battery, you must ensure that the voltage
reaching the devices is 12V. If the vehicle battery supplies power at a voltage other than 12V, you must insert a
transformer between the battery and the device, as in figure 8 below.
In order to ensure that the transformer is compatible with the vehicle battery, it is recommended that it be purchased
in the country in which it will be used. In addition, make sure the capacity of the transformer is more than sufficient
for all of the devices connected to it. You can calculate the required capacity by calculating the sum of the power
consumptions of each device drawing power from the battery through the line. For example, if two cameras and a
sensor are connected directly to the battery, and each one uses 2W, the total requirement is 6W. Allow an additional
margin of 20-30% when you select the transformer. Thus, if the devices require a total of 6W, get a transformer that
supplies at least 7.2W.
NOTE:
You can convert Amps to Watts using the following formula:
Volts * Amps = Watts
For example, a 12V device that operates at 250 mA consumes 3 Watts: 12 * 0.25 = 3.

Configuring the Power-Supply Activator
When the power supply to devices is routed through the activator connector, as described above, the activator must
be configured correctly in the CVG-M's configuration: the Normal Status of the activator must be set to Closed, as
in the illustration below. (For additional information about configuring the activator, please refer to the Embedded
Video Gateway System Guide, under Configuring Sensor and Activator Settings.)

Connecting Devices to the CVG-M
This section explains how to connect devices such as cameras or a sensor to the CVG-M unit.
NOTE:
If you are connecting devices to a CVG-M in a vehicle, make sure that all the devices are designed to
function properly under mobile conditions (temperature range, vibrations, power supply, etc), that they
are all installed in accordance with their manufacturer's requirements, and that the devices and all
cables are properly installed and firmly fastened so that they will not become dislodged when the
vehicle moves. It is highly recommended to consult vehicle experts before installing external devices.
Connecting Cameras
Two cameras can be connected to the CVG-M. 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-M.
NOTE:
A cable with a male RCA connector can be connected to a female BNC connector by using an RCAto-BNC adaptor.
Figure 10: RCA-to-BNC adaptor
 To connect a cam era:
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, as explained under Supplying Power to Devices
Connected to the Unit, page 11.
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.
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.
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.
Connecting Devices to the CVG-M

 To connect an RS232 P TZ 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 P TZ 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 11).

SerVision
CVG-M 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-M 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 sw itch directly to the unit:
1. Install the sensor or switch in its desired location in accordance with the manufacturer's instructions.
2. Connect the two wire contacts of the sensor or switch to the In1 connector on the rear panel of the CVG-M, as
illustrated in figure 13. 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.

CVG-M Installation Guide
Connecting Sensors Using an ADAM Module
If you want to connect additional dry sensors to the CVG-M, 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 21.
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)

The instructions below explain how to connect sensors to the CVG-M 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 an Activator
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 21).
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.
2. Connect the two contacts of the activator to the Out1 connector on the CVG-M, as illustrated in figure 19. It
does not matter which wire you connect to each contact.

Connecting Sensors and Activators Using an IA Relay Board
If you want to connect additional dry sensors and/or activators to the CVG-M, 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-M’s configuration utility.
NOTE:
Alternatively, you can connect additional sensors using an ADAM module, as explained under
Connecting Sensors Using an ADAM Module, page 17. Sensors that are connected through an ADAM

CVG-M Installation Guide
Connecting the CVG-M to a Network
The CVG-M can 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). The unit also contains
a cellular modem that allows it to connect wirelessly to a cellular network and, through the cellular network, to the
internet. A cable-based network connection should be used to access the CVG-M unit when it is first set up in order
to configure it. Once it is set up, either type of network connection can be used. For information about configuring
the network settings so that you can connect to the unit, please refer to the Embedded Video Gateway System Guide.
LAN Connection
You can connect the CVG-M to a cable-based LAN. When the unit is connected to a LAN, it cannot connect to a
cellular network.
 To connect the CVG-M unit to a LAN:
• Connect the Ethernet Out connector on the CVG-M unit to a LAN connection point (a hub, wall socket, or
any other connection point) using the supplied Ethernet cable (see The CVG-M Package, page 4).
Cellular Connection
The CVG-M can connect to the internet using a built-in 3G GSM UMTS/HSDPA cellular modem. In order to use
this feature, you must acquire an appropriate SIM card from a cellular provider and insert the SIM card into the
unit. Once the SIM card is inserted, the unit is configured to use it, and the cellular antenna is connected, the CVGM can transmit video streams, event information, and GPS location data to client applications from any location in
which the relevant cellular network can be accessed.
If a SIM card is installed in the CVG-M and properly configured, the unit automatically attempts to connect to the
cellular network. Nevertheless, the unit can only connect to one network at a time, and it gives priority to a LAN
connection. Thus, if the unit is already connected to a LAN, it will not attempt to connect to the cellular network
when you insert a SIM card. On the other hand, if it is already connected to a cellular network, and you connect it to
a LAN, it will automatically disconnect from the cellular network and connect to the LAN.
Connecting the Cellular Antenna
The supplied cellular antenna must be connected to the CVG-M in order for it to connect to a cellular network.
 To connect the cellular antenna:
1. Screw the connector on the end of the antenna wire to the Cellular Antenna connector on the side of the unit.
2. Place the other end of the antenna as high up as possible, minimizing obstructions between it and the sky. If
the unit is installed in a vehicle, make sure the antenna is attached securely to the vehicle so that it will not
come loose when the vehicle moves.
Inserting the SIM Card
You must insert a SIM card in the CVG-M in order for it to connect to a cellular network.
NOTE:
If the SIM card requires a PIN, configure the modem settings as described in the Embedded Video
Gateway System Guide before you insert the SIM card into the unit. Otherwise, the unit may attempt to
use the SIM card to connect to the network with an incorrect PIN. Attempts to use the SIM with an
invalid PIN may cause the SIM card to be locked.

Connecting the CVG-M to a Power Source
The CVG-M can be connected either to an electrical outlet using the supplied power-supply cable, or to the ignition
of a vehicle, using the supplied power cord.
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 27: Power LED
NOTE:
When the start-up process is completed, if the Power LED does not flash – if 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.
Typically, the CVG-M unit is configured in an office setting and then installed in the vehicle. The power-supply
and power-connector cables are used to connect the unit to a standard electric outlet for configuration. After
configuration, the cables are disconnected from the unit, so that it can be connected to the vehicle battery.
NOTE:
It is recommended that only a vehicle installation specialist connect the unit to the battery.
Connecting the Wire Connector to the Unit
Demo units and small orders are supplied without a wire connector in the Power connector on the rear panel of the
unit, as in figure 29. In large orders, the units are supplied with wire-connectors connected to the Power connectors
on the units, as in figure 30 (because only a limited number of power-connector cables are supplied with large
orders, and every unit requires a wire connector).
Figure 28: Wire connector
Connecting the CVG-M to a Power Source
29
SerVision
CVG-M Installation Guide
Figure 29: No wire connector connected to Power connector
Figure 30: Wire connector connected to Power connector
In order to connect the unit to the vehicle battery, the wire connector must be connected to the Power connector on
the unit. Therefore, if your unit was supplied as a demo unit or as part of a small order, you must remove the wire
connector from the power-connector cable and connect it to the unit.
 To connect the w ire connector to the unit:
• Plug the wire connector into the Power connector on the rear panel of the unit, and tighten the screws to
secure it.
Connecting the Unit to an Electrical Outlet
If a standard electrical outlet is available, the unit can be connected to it. For example, if you want to configure or
test the unit indoors, you can power the unit in this way.
WARNING: Only the power supply cable that came with the unit (or with the shipment) should be used to
connect the unit to an electrical outlet. Use of a power supply other than the one provided in the
package may cause irreparable damage to the unit.
NOTE:
If the unit was supplied as part of a large order, power-supply and power-connector cables were not
supplied for each individual unit. The cables that were supplied should be reused for all the units (see
The CVG-M Package, page 4).
 To connect the CVG-M to a standard electrical outlet:
1. Connect the power-connector cable to the power-supply cable.
2. If a wire connector is connected to the Power connector on the unit, unscrew the screw holding it in place, and
remove it.

CVG-M Installation Guide
3. Connect the power supply cable to the Power connector on the unit.
4. Plug the power-connector cable into the outlet.
Connecting the CVG-M to a Vehicle Battery
Normally, the unit is connected to a vehicle battery and to the ignition using 16 AWG cable (not supplied). This can
be done in one of two ways:
• Connecting the unit directly to the battery and the ignition
• Connecting the unit to a power source in the vehicle that is only active when the ignition is on
When the unit is connected to the battery and ignition in one of these ways, it automatically powers up when the
ignition is switched on. If the unit is connected directly to the battery, it can be configured to operate only when the
vehicle ignition is on and to shut down automatically soon after the ignition is turned off. Otherwise, it will shut
down automatically when the ignition is turned off.
For testing and evaluation purposes, the unit can also be powered by connecting it to the vehicle’s cigarette lighter,
if the vehicle has one. This method connects the unit to the battery and the ignition quickly and easily, but it is not
normally suitable for permanent connections, because it is difficult to install the unit and the wiring securely in
appropriate locations when this method is used.
In addition, it is possible to connect the unit to the battery alone, without connecting it to the ignition. In this case,
the unit runs continuously, whether the ignition is on or not, as long as the battery can supply power to it. Because
of the drain on the battery, connecting the unit in this way is also only recommended for limited periods of time for
testing and evaluation purposes.
NOTE:
The ignition connector (IGN) of the Power connector MUST be connected. If it is not, the unit will not
start. If you wish to use the vehicle’s ignition connection, connect it to this connector. Otherwise, short
this connection to the positive (+) connector of the Power connector block. For additional information,
see step 4 below (pp. 32–33).
NOTE:
To connect the unit only to the battery, 16 AWG red and black cable (not supplied) is required.
WARNING: It is very important to ensure that the unit is connected to the power source in such a way that there
are no voltage fluctuations when the unit is in operation. Voltage fluctuations can interfere with the
timestamps of recorded video, making it impossible to retrieve the video from the unit's storage
media.
 To connect the CVG-M to a vehicle battery:
1. If the wire connector is not plugged into the Power connector on the unit, plug it into the Power connector on
the rear panel of the unit, and tighten the screws to secure it.

•• Connect one end of the red wire to the positive (+) connector of the Power wire connector (the middle
connector in the block).
•• Connect the other end of the red wire to the positive (+) connector of the vehicle battery or power source
3. Using 16 AWG black cable, connect the unit to the vehicle battery as follows:
•• Connect one end of the black wire to the negative (-) connector of the Power wire connector (the right
connector in the block).
•• Connect the other end of the black wire to the negative (-) connector of the vehicle battery or power
source
4. If you need to connect the unit to the ignition, using 16 AWG black cable, connect the IGN connector to the
ignition, as illustrated in figure 34. If you do not need to connect the unit to the ignition, using 16 AWG black
cable, connect the IGN connector to the positive (+) connector of the Power wire connector (the middle
connector in the block), as illustrated in figure 35.

Appendix 2: Using the 12VDC Power Out Connector
The CVG-M 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-M in this way. If the
devices connected to the 12VDC Power Out connector draw a total of more than 250 mA at one time, 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, a battery, or the vehicle
battery, as explained above (see Supplying Power to Devices Connected to the Unit, page 11).
Nonetheless, in certain cases it may be advantageous to supply power to one or more devices through the 12VDC
Power Out connector. It is not recommended to use the connector to supply power to cameras. If you are interested
in connecting other devices to the connector, please consult a SerVision technician (at support@servision.net) to
discuss the feasibility of connecting them. Bear in mind that the CVG-M unit can supply a maximum of 250 mA
(3W at 12V) of power through the 12VDC Power Out connector. Before you contact technical support, consult the
device documentation of each device you want to connect to the CVG-M unit to ascertain its actual power usage.
NOTE:
Devices that draw their power through the 12VDC Power Out connector on the CVG-M are turned off
automatically when the CVG-M shuts down, because they do not receive any power from the unit
when it is off.
WARNING: It is not recommended to use the 12VDC Power Out connector to supply power to cameras.
