Stack DVR2 Users Guide 11
A Regulated 12 volt 2.1 mm power connector has been
provided for powering microphones.
Note: The regulated 12 volt power also supplies the cameras,
maximum total load is 1.0Amps. If the current required is
greater than 1.0A, you must provide a separate power
supply
.
! If audio recording is not required, it may be disabled to

Connect the Record Switch and Recording Lamp lead to the

more than 25mA max.
Connect a permanent DC supply of between 9 and 20 volts
(or 20 to 50volts for the High Voltage Option ST9399) to the

independent switch can be added to isolate the module.
