Q: Camera stops when engine is off

The yellow ACC wire senses ignition status to switch between driving and parking mode. If the mode doesn’t change, ensure the ACC wire is connected to an ignition-triggered circuit and parking mode is enabled on the menu.

Q: Camera stops unexpectedly during parking mode

This usually occurs if the battery reaches low-voltage cutoff or the parking timer ends.

Q: Camera keeps recording after turning off the engine

Confirm the ACC wire is correctly connected to an accessory circuit (not constant power).

Q: How to install the dash cam hardwire kit?

Connect the red wire to a constant power source using a fuse tap. Connect the yellow wire to a circuit that only has power when the ignition is on (ACC). Securely ground the black wire to an unpainted metal point.

Q: Does hardwire cable have low voltage protection function?

Yes, the hardwire kit features built-in low-voltage protection. It automatically cuts power to the dash cam when your vehicle's battery drops to 11.8V (for 12V systems) or 24.8V (for 24V systems), preventing battery drain.
