To power up and power down,
On the initial configuration:
The NVR is started when the vehicle ignition is started sensing the voltage. The NVR
supports configurable power ON/OFF delay time. Low power protection is also supported.
See page 125 for the delayed ON/OFF configuration (see Settings > System > Power
After the initial connection,
When the vehicle engine stops, the system should start flushing the cached contents in
system memory and gracefully shut down. The NVR can be configured to power down later
than the engine stop using the battery power.
Press the Reset button for longer than
5
seconds can restore system defaults.

The NVR supports low battery power detection and automatic power-down when voltage drops
