Introduction
The installation of the 10-8 Patrol Car video system breaks down to some
very simple steps. The basic connection for video and audio are very similar
to a VCR or DVD player. The one area that differs from what you may have
done in the past is the connections for the alarm inputs . There are four (4)
sensor wires that will activate the recorder anytime voltage is applied to any
of the four (4) wires.
To help make the connections easier, the cables that attach to the back of
the DVR each use a different type of connector. Familiarize yourself with
the inputs in the picture on pages 12 and 13.
You will need two 12 volt power sources - a constant 12 volt
power source and a switched 12 volt power source.
You will also need a ground source.
We strongly recommend that the power source be from switched power
that is only hot when the vehicle key is in the ‘ON’ position. This should be
a five (5) amp fused power source. To eliminate interference, there should
be no other equipment on this circuit.
It is also very important that the ground be a good chassis
ground source and not tied into the ground of other equipment.
When the DVR’s door is unlocked to allow access to the SD
cards, the system is automatically powered down to protect the
files on the SD cards. When the door is locked, the DVR system
will be able to accept power and turn on again.
