Essential Power Solution for Activating Parking Mode

The VIOFO HK4 is a USB-C hardwire kit that connects directly to your vehicle’s fuse box, supplying constant power to your dash cam—even when the engine is off. This enables the dash cam’s parking surveillance features to function effectively, offering continued protection while your vehicle is unattended.

Whether you’re parked overnight or for a quick stop, the HK4 helps your dash cam stay active and alert. With integrated battery protection, automatic ACC detection, and a clean installation setup, it’s the recommended solution for unlocking 24/7 recording functionality.
