Low voltage cutoff works great. Havent tested parking mode yet.

Great kit with lots of options

If like me you needed to tap multiple fuse sizes and also weren't sure what fuse types they were, the kit with all the fuse holders and fuses for just a few dollars more makes the installation process easy.

DIDNT LIKE THAT THE PACKER SQUISHED THE FUSE HOLDER WIRE 2 PACK INTO THE KIT BOX, KINKING THE WIRE AND BENDING CONNECTION WHER IT IS WIRED TO FUSE INSERT PORTION. NOT HAPPY WITH THAT AT ALL.

Why Use a Hardwire Kit?

2.jpg__PID:5aff87c3-e3ed-4535-bac5-44a3c7e76009

The hardwire kit provides continuous power to your dash cam via the fuse box (VCC, ACC, GND), replacing the need for a cigarette lighter and ensuring seamless coverage from the moment you start driving.

Even when parked, the hardwire kit keeps your dash cam running by tapping into your vehicle's fuse box. It captures every important moment and automatically powers down before draining your car battery.

Seamless Parking Mode Switching

With ACC detection, the dash cam seamlessly enters parking mode when the vehicle's engine is turned off and resumes normal recording once the vehicle is started.

Battery Discharge Prevention

The HK3 Hardwire Cable provides continuous power to your dashcam in parking mode until your car battery voltage drops to the configured threshold.

Configurable Voltage Cut-off

VIOFO HK3 Hardwire Cable offers 4 voltage cut-off options. When the vehicle's battery voltage drops to the selected threshold, the HK3 stops supplying power to the dashcam, helping prevent battery discharge.

12V / 24V Compatible

The HK3 Hardwire Cable connects the camera directly to cars, trucks, buses, SUVs, or big rigs for continuous power. It accepts voltage from any vehicle running on 12–24V.

1. Locate Your Fuse Box

Fuse box locations and types can differ between car models, years, and variants. Refer to the car manual for specific instructions.

6-2.jpg__PID:35bac544-a3c7-4760-8955-7d40c5f7f7e1

2. Identify Battery & ACC fuses

To check fuse locations, use a multimeter on DC voltage after turning off the vehicle. 12V or 24V indicates Battery location, while 0V indicates ACC location.

6-3.jpg__PID:bac544a3-c7e7-4009-957d-40c5f7f7e1b8

3. Recheck the Fuses

With the ignition turned on, use the multimeter to test the Battery and ACC fuse positions identified in Step 2. Both should show a voltage of approximately 12V or 24V. If not, repeat Step 2.

Cable Connection

The HK6 features an always-on Bluetooth broadcast that transmits the car battery voltage—no pairing or user interaction required. Your dashcam automatically searches for the HK6's signal, reads the voltage, and displays it on the recorded video for real-time monitoring.

*Currently supports: A229 Ultra, A119 M Pro, A329S Series. App support for additional models is on the way!
