POWER INPUT CONNECTOR
The mDVR514M 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 mDVR514M uses this signal to trigger the power shut-
off delay and the timing circuitry. The mMVR514M 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.

CAMERA 1,2,3, AND 4 CONNECTORS
The mDVR514M supports a maximum of 4 cameras. These Micro-fit connectors are used to connect the
four camera inputs to the mDVR514M system (video and audio). Also included in each camera connection is
DV12V Out to power the camera. You can refer to the cover of the DVR for the PIN assignments of each connector.
If any of these cameras are not connected properly (for instance loose cables, unplugged etc…) than the
mDVR514M intelligently notifies the end-users with “NO VIDEO” on the preview screen. Camera inputs are labeled
CAMERA 1, CAMERA 2, CAMERA 3, and CAMERA 4.
