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** A: This usually occurs if the battery reaches low-voltage cutoff or the parking timer ends. **Q: Camera keeps recording after turning off the engine** A: Confirm the ACC wire is correctly connected to an accessory circuit (not constant power). **Q: How to install the dash cam hardwire kit?** A: 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?** A: 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for parking mode! *by G***A on 13 December 2025* This kit connected to my viofo a119 mini 2 dashcam.
