Power Supply Connector Cable
This terminal is connected to
the 6-pin power interface on
the rear panel of the MDVR.
See FIG. 2 for its location.
Check that the battery provides voltage between 8V~36V
before connection to prevent damage to the device.
Be aware of where each of the ends of each wire are after
you have connected it to the battery to prevent the cable
damaging the device from a short circuit.
We recommend connecting the yellow wire to the ignition
cable, otherwise the shutdown feature will not function
We recommend connecting the device directly to the
vehicle’s battery. If this is not possible, connect to the
vehicle’s fuse box, bypassing the ground connection which
may influence the normal operation of the MDVR due to
The wire that connects the power cable harness to the
vehicle’s battery should be a minimum diameter of
Connect the 6-pin white plug to the 6-pin power input port
on the rear panel of the MDVR. The red and black cables are
directly connected to the battery of the vehicle, i.e. positive
terminal and negative terminal respectively, or to the main
The yellow cable is connected to ACC, the vehicle control
circuit switch (used to start the vehicle’s motor). The unit will
automatically power on when the car key is in the ON position
and power off when the key is in the OFF position.
When the device is not installed in a vehicle (such as monitoring
systems in a bus station, logistics transfer) or under testing
conditions, you can use a switching power above DC12V-5A to
supply the MDVR the proper signal. In this case, twist the red
and yellow cables together into a single cable and connect it to
the positive terminal. The black cable is then connected to the
negative terminal separately.
Step 6: Connect the power cord.
