VIOFO HK3-C Type-C Hardwire Kit for A139 and A139 PRO Dash Cameras

The VIOFO HK3-C is a vehicle hardwire kit that provides continuous power to VIOFO A139 and A139 PRO dash cameras for 24-hour surveillance. It connects directly to your fuse box, replacing bulky cigarette lighter adapters with a clean, concealed installation. This kit is essential for users requiring parking mode functionality to capture events while the vehicle is unattended.

Continuous 24/7 Power: Hardwire Kit for Parking Monitoring

The VIOFO HK3-C provides continuous power to your dash camera by tapping directly into the vehicle fuse box. This replaces the standard cigarette lighter plug, ensuring the camera remains active even when the engine is turned off. It is the primary method for enabling parking surveillance to protect your vehicle while it is parked in public or private lots. Ideal for drivers who require constant security coverage.

Automatic Parking Mode Switching via ACC Detection

The hardwire kit utilizes ACC detection to automatically signal the dash camera when the engine is switched on or off. When the ignition is cut, the unit seamlessly transitions into its configured parking mode. Upon starting your vehicle, it resumes normal, high-priority recording mode without user intervention. This mechanism ensures consistent operation for daily commuters and fleet operators.

Battery Discharge Prevention with 4 Voltage Cut-off Options

The VIOFO HK3-C includes 4 configurable voltage cut-off options to protect your car battery from excessive depletion. When the vehicle battery voltage drops to the selected user threshold, the hardwire cable automatically stops supplying power to the dashcam. This prevents the common risk of a dead battery following long periods of parking surveillance. It provides peace of mind for users parking for extended durations.

12V to 24V Vehicle Compatibility

This hardwire kit is fully compatible with any vehicle electrical system running on 12V or 24V power. This versatility allows for installation across a wide range of vehicles, including standard cars, trucks, SUVs, buses, and heavy-duty rigs. It delivers a stable, consistent voltage flow regardless of the vehicle type. It is designed for professional drivers and private vehicle owners alike.

Type-C Connectivity and 13.1 Foot Cable Length

The HK3-C features a standard Type-C USB plug designed specifically for the VIOFO A139 and A139 PRO dash camera systems. The total length of the cable is 13.1 feet (4M), providing sufficient reach to route wires cleanly through most vehicle headliners and trim panels. This length accommodates complex installations in larger vehicles and trucks. It is a necessary upgrade for a tidy, professional dashboard setup.

Frequently Asked Questions

Does the VIOFO HK3-C hardwire kit include fuse taps?

No, the kit does not include fuse taps. You must source the correct fuse tap type (ATO, Mini, or Micro2) to match your vehicle fuse box, or purchase the VIOFO Full Set Fuse Tap kit separately.

Is the HK3-C compatible with older VIOFO A129 series cameras?

No, the HK3-C is not compatible with Mini Port cameras such as the A119V3, A129 Duo, A129 Duo IR, A129 Pro Duo, or A129 Plus Duo. It is designed specifically for the Type-C power port on the A139 and A139 PRO models.

Will this hardwire kit drain my car battery?

No, the kit prevents battery drainage by using configurable voltage cut-off settings. It automatically disconnects the dashcam once the vehicle battery reaches your selected threshold to ensure you can always start your engine.

What tools are needed to install the VIOFO HK3-C?

Installation typically requires a multimeter, needle-nose pliers, a fuse puller, and a trim removal tool. These tools allow you to identify live fuses and tuck the 13.1-foot cable under your vehicle panels for a concealed install.
