VIOFO USB‑C hardwire kit for dash cams














VIOFO USB‑C hardwire kit for dash cams

Parking mode with automatic ACC switching
The kit keeps the camera active even after the engine is off and, thanks to ACC detection, automatically switches between driving and parking modes. No worries, no manual adjustments.

Battery protection with adjustable threshold
The integrated discharge protection monitors voltage and, when it drops below the selected level, safely cuts power to the camera. Four threshold levels are available.

USB‑C connection and easy installation
The right-angle USB‑C connector makes cable routing easier, and the fuse tap adapters (ATS, ATC, MICRO2, MINI) ensure a quick, clean, and safe install without altering the factory wiring.
The VIOFO hardwire kit provides your dash cam with reliable power even when the engine is off, allowing it to operate in parking mode and capture events around the vehicle. Built‑in ACC detection automatically switches between driving and parking modes without driver intervention.
Smart low‑voltage protection monitors the vehicle's electrical system and disconnects the camera when voltage falls below the selected level. The cutoff can be set to four levels to suit your vehicle and usage. The kit is compatible with 12/24 V systems, and the USB‑C connector makes it easy to connect to supported VIOFO cameras.
