Regardless of the vehicle type the the normal layout of a DVR system will remain similar with the main DVR mounted in
the cabin area where access to power is possible. All cameras will be connected by cables and these will need to be run
through cable channels where possible and should be fixed into place so that they cannot be inadvertently caught and
damaged.
Trucks with “cab over” layout will require the cables going outside of the cab to be run with other wiring through pivot
points.
The DVR is supplied in a metal chassis which needs to be firmly mounted. Remove the DVR from chassis and attach using
suitable fixings allowing sufficient room to access the rear panel where the connections are made.
Always ensure that the DVR is accessible so the hard drive can be removed when necessary.
Cables should be left with enough slack to allow the DVR to be removed. Do not tightly bunch the cables close to the DVR
as this may place undue strain on the connectors and will hamper access in the future.
Different cameras will be used depending on the vehicle and application, it is recommended that standard cameras
supplied by Chipatronic are used as these have been tested with the system and are high resolution models suitable for
automotive video recording applications.
Camera mounting will be subject to the cameras used and the vehicle. Installers should check with the vehicle operator
before commencing installation to ensure that these are able to capture the required views.
A portable camera tester is available to assist in setting up cameras and to connect to the DVR to check operation and
setup. Contact Chipatronic for details.
Sensor input 3 Grey wires
Connect Sensor 1 wire to the Trigger
1 wire on the monitor (Brown) and
then to the Reverse light circuit.
When the truck goes into Reverse
the monitor will turn ON and show
the rear camera (CAM 4).

(CAM1) on the monitor
Using DVR Video Out as a Reverse Camera
The DVR has 2 different video outputs; HDMI and CVBS. For a Reverse Cam application only a CVBS monitor can be used.
The DVR will have been configured for this functionality prior to delivery if this was specified at time of order but it is
recommended that this operation is bench tested prior to vehicle installation to ensure that it works as expected as
additional connection to the vehicle’s electrical system will be required which cannot be tested.
As standard, Sensor 1 will be the DVR trigger input and this should be connected to Trigger 1 on the monitor.
For automatic operation in reverse gear, this must be connected to the reverse light circuit so that a voltage signal is
applied to both of these triggers together. The monitor will usually be in standby mode (powered off using the button on
the monitor) and will turn on when voltage is applied with AV1 (Ch. 1) being displayed which will be a single camera
output from the DVR, usually Ch. 4 which should be the rear camera. Please ensure that cameras are connected to the
correct DVR inputs as specified or the incorrect image will be shown.
Up to 3 cameras can be switched in this manner to achieve specific views on selection from the DVR but must be
configured in the DVR settings. This is best done prior to the system being supplied but can be done later if required.
