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.
