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.
