POWER INPUT CONNECTOR
The mDVR510x has a built-in Intelligent power switcher that can operate from +8V ~ +24V DC-IN. The
ON/OFF signal connects to the vehicle’s ignition signal. The mDVR510x uses this signal to trigger the power shut-
off delay and the timing circuitry. The mMVR5100 will remain ON until the shut-off delay time has been reached.
The system will then go through its normal shutdown procedures before completely powering down. The GND
(Common DC ground) signal should be connected to the vehicle common ground.
