1.5.4 Connecting power
Single supply
Power is supplied to the Venom docking adapter from an external DC power supply. From the
Venom docking adapter power can be supplied both to the Venom and the Viper via the
multicore cable. In this case, no separate power supply is needed for the camera. The source
switch must be set to the Multicore position.
When an external DC power supply is used to power both the Venom and the Viper use a DC
power supply that can supply at least 14 V~ 8A continuous.
Dual supply
Connect a DC power supply to the Venom docking adapter to power the Venom unit. When
the Venom is powered separately use a DC power supply that can deliver at least 14 Vdc ~ 4A
continuous.
Connect a DC power supply to the DC IN power socket on the Viper rear connector panel. This
socket accepts a DC supply of 12V Nominal (11V to 17V) to power the camera. Nominal power
consumption is 44W.

Note
Keep the power cable to the Docking Plate as short as possible (less than 2 m is
recommended).
If power loss occurs during recording the current take will be lost. If it occurs while erasing
Takes, the erase process will need to be repeated once power has been restored. If the power
is lost while playing back a Take, or in idle mode, no data is lost or affected.
Battery pack
If a battery pack is used and the system voltage drops below 10.0V, the power LED on the
Venom flashes to give a warning. If the voltage falls below 9.5V, the Venom system will close
down and show the following message on the display:
