The biggest advantage is that it provides constant power without needing to use the cigarette lighter port. Once installed, the dash cam turns on and off automatically with the car, and parking mode works exactly as intended. The Type-C connection feels solid and modern, and compatibility with multiple VIOFO models is a big plus. I really appreciate that it comes with a full set of fuse taps. That saves time and extra purchases, especially if you’re not sure which fuse type your vehicle uses. The wiring quality feels good, and the voltage protection gives peace of mind that it won’t drain the car battery. Installation itself is straightforward if you’re comfortable accessing the fuse box. For someone with zero experience, it may take a bit of time or require watching a guide, but that’s expected with any hardwire kit and not a flaw of the product. Overall, this is a solid and reliable accessory if you want a clean dash cam setup with parking mode enabled. Well made, complete kit, and works as advertised. Easy 5 stars. ## Features - 【Fuse Tap Not Included】Note: The installation of the harewire cable requires the connection of the circuit fuse taps.

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 ### ⭐⭐⭐⭐⭐ Build quality *by J***H on 22 September 2025* Exactly as mentioned, good quality, I personally recommened this ### ⭐⭐⭐⭐⭐ Review *by A***Y on 7 February 2026* This hardwire kit does exactly what it’s supposed to do and makes installing a VIOFO dash cam much cleaner and more professional.
