HK6-F wires your T330 or T340 to the vehicle fuse box for constant 12–24V power, so the camera can keep recording while the engine is off. It adds ACC detection, Hybrid Parking Mode support, four selectable battery cut-off voltages and automatic vehicle-voltage display over Bluetooth.
The important compatibility and practical details are kept up front so you can identify the correct accessory without relying on a similar-looking part.
HK6-F is VIOFO’s dedicated hardwire kit for the T330 and T340 series. Parking mode on these cameras requires a hardwire connection.
Match this SKU and the stated camera family, connector, position or cable length before ordering.
HK6-F is designed around the parking features of the T330 and T340, with modular cabling, voltage reporting and low-power operation alongside the usual ACC switching and battery protection.
The input and output leads plug into the HK6-F control module. That makes cable routing easier during installation and means the module can be changed without rewiring or removing the existing cable run.
HK6-F broadcasts the car battery voltage over Bluetooth with no pairing or user interaction. The T330 and T340 search for the signal automatically, read the voltage and show it on the recorded video for real-time monitoring.
With ACC detection, the camera enters parking mode when the engine is turned off and returns to normal recording when the vehicle is started.
With the T330 and T340 series, HK6-F supports Hybrid Parking Mode, switching between normal parking recording and Low Power Impact Detection according to the configured cut-off time, cut-off voltage and cut-off battery pack capacity.
HK6-F powers the camera in parking mode until the battery falls to the selected threshold, then stops supplying power to help prevent battery discharge. It draws no more than 300μA when the dash cam is off.
Set the HK6-F threshold to suit the vehicle and installation using the slide switch on the module. Once the battery reaches that threshold, the kit stops supplying power to the dash cam to help preserve starting capacity.
HK6-F accepts 12–24V vehicle input, so it suits cars, SUVs, trucks, buses and larger commercial vehicles.
Battery+ (red) goes to a constant-power fuse slot, ACC (yellow) to a switched fuse slot and Ground (black) to the chassis. The detachable module then feeds the camera through its USB Type-C plug.
The vehicle-side lead is 1000mm, the hardwire box is 60.6mm long and the camera-side USB Type-C lead is 3000mm.
Current compatibility and practical details checked against the matching VIOFO accessory family.
HK6-F is VIOFO’s dedicated hardwire kit for the T330 and T340 series. Hybrid Parking Mode and on-video voltage display are supported on the T330 and T340 series.
The compatibility and installation questions that matter most for this accessory.
The permanent feed powers parking recording, while ACC tells the camera whether the ignition is on so it can switch operating modes automatically.
It stops drawing from the vehicle battery when voltage falls to the selected threshold, helping preserve enough charge to start the vehicle.
No. Match the exact hardwire-kit model to the dash cam. Parking features and power signalling differ between VIOFO families.
