Which cameras fit the HK3?
Use the mini-USB HK3 with A119 V3, A129 Duo, A129 Duo IR, A129 Plus Duo or A129 Pro Duo. Other VIOFO models need their own compatibility check.
Does this fit A119 Mini 2 or A139?
No. Those cameras use USB-C hardwire kits. A shared brand name does not make the HK3 connector interchangeable.
How long is the cable?
The cable is 4m, approximately 13.1ft. Measure the actual route from the fuse box to the camera, including the path around trim, before installation.
Does the HK3 enable parking recording?
It provides the power and accessory signal a supported camera needs. Enable parking mode in the camera and follow its instructions. Auto-event, time-lapse and low-bitrate options depend on the camera model and settings.
Can it guarantee overnight recording?
No. Parking runtime varies with battery charge and condition, temperature, camera demand and the cut-off setting. The kit stops supplying power when the selected voltage threshold is reached.
Can I use it in a 24V vehicle?
Yes. The HK3 supports 12V and 24V vehicle systems. Use the settings marked for the vehicle voltage and follow the kit instructions.
Are fuse taps included?
Not by default. Match an Add-a-Fuse kit to the vehicle fuse type and selected circuits. The camera model does not determine which fuse tap fits.
Where do the three wires connect?
Red connects to a suitable constant-power circuit, yellow to a suitable switched accessory circuit and black to ground. Check both ignition states and follow the vehicle and kit instructions; keep wiring clear of airbags and moving parts.
