Wire Ignition Signal
The mobile NVR is provided with MCU-based ignition power control. To control the ignition power, the
mobile NVR needs IGN signal. The IGN input port is built at the rear panel of the mobile NVR by a 3-pin
pluggable terminal block (shared with DC-in power ). Follow the guide below to wire the ignition signal:
1. Connect car b line (12V for sedan, 24V for bus/truck) to V+.
2. Connect car battery -/GND line to GND.
3. Connect ACC line to IGN.
Caution
1.
Make sure your DC power source and IGN signal share the same ground.
2.
The IGN input accepts max. 35VDC. Supplying power over 35VDC may damage the
system.
