Not in the box: Fuse taps. You need two to connect it to your fuse box: one on a constant fuse, one on an ignition fuse.

Hardwiring is part of every dash cam install we do. We hide the cable behind the trim, connect it to the right fuses and set up parking mode, and the work is covered by our lifetime installation warranty.

The Viofo HK3-C is the hardwire kit for the Viofo A139 and A139 Pro. It wires the camera to your fuse box so it can record in parking mode with the engine off.
Viofo A139 and A139 Pro (1, 2 and 3 channel). Not for the A119 V3 or the A129 series, which use the Mini-USB HK3.
You need two fuse taps: one on a constant fuse and one on an ignition fuse.
There are three ways to power a dash cam. Only two of them give you parking mode.
Wires to your fuse box with fuse taps. The neatest install: the cable disappears behind the trim, the 12V socket stays free, and parking mode runs with a low-voltage cut-off. Most kits need two fuse taps, sold separately.
Plugs into the diagnostic port under the dash. Parking mode without touching the fuse box, and easy to take out at lease return. It has to come out when a mechanic needs the port, and some vehicles turn the port off when parked.
Plugs into the cigarette lighter socket. Nothing to wire, and handy as a spare for a second vehicle. In most vehicles the socket turns off with the engine, so there's no parking mode.

Only if you want parking mode. For recording while you drive, the 12V cable that came with your camera does the job. Parking mode needs power with the engine off, which means a hardwire kit to the fuse box, an OBD-II cable, or a dash cam battery pack.
Not to the point of stranding you, when it's set up right. Every hardwire kit and OBD-II cable we sell shuts the camera off at a set voltage, either with a switch on the kit or in the camera's settings. An old battery and cold weather cut the margin, so set the cut-off higher in winter. If your vehicle sits for days at a time, a dash cam battery pack keeps your starting battery out of it completely.
For a hardwire kit, yes, usually two: one on a constant fuse and one on an ignition fuse. Most kits don't include them. If this one does, it says so under What's in the box. Fuse taps come in five sizes, so check yours first with our fuse identifier.
Both give you parking mode. A hardwire kit is the tidier, permanent install and leaves the OBD-II port free. An OBD-II cable is quicker to fit and easier to remove, which suits leased vehicles. Some vehicles turn the OBD-II port off when parked; on those, a hardwire kit is the way to go.
Use the cable made for your camera. The plugs can look the same, but cables differ in output, in how they tell the camera the engine is off, and in their cut-off. The wrong one can leave parking mode not working. Use the fit check above, or text us your camera model.
The length is under At a glance. In most cars and SUVs, 3 to 4 metres reaches from the windshield to a fuse box under the dash. If your fuse box is in the trunk or under the hood, or you drive a truck or van, pick a longer cable or text us and we'll tell you what fits.
If you're comfortable finding a constant and an ignition fuse with a test light, yes. Budget about an hour, and follow the steps in the user guide. Or have us do it at our Markham shop: hardwiring is part of every dash cam install, with our lifetime installation warranty.
