VIOFO HK4 Hardwire Kit – USB-C, 4-Level Cut-off for Parking Mode

Unlock Parking Mode on Your VIOFO. The HK4 hardwire kit adds constant power with four battery cut-off levels

Your VIOFO does its best work when you are not in the car, but the cigarette socket dies with the ignition and takes Parking Mode with it. The HK4 taps constant power from the fuse box instead, so the camera keeps watching a supermarket car park or a street park overnight, and shuts itself down at whichever voltage threshold you pick before your battery is in trouble.

Trusted AU store: We're an authorised AU reseller, shipping from Melbourne within 24 hours^*. You get a 12-month warranty on this accessory, local technical support, and our 30-Day No-Worries returns.

Who This Isn't For: This is USB-C, so older Mini-USB VIOFO cameras like the A119 V3 and A129 need the Mini HK3 instead. If you would rather not open the fuse box at all, the OP100 plugs into the OBD port. For hybrid parking mode on the A329S family, look at the HK6.

DCG Score & Highlights

What We Love

• Four low-voltage cut-off levels from 11.8 V to 12.4 V, so you can match it to your battery's condition
• Generous 4 m run, enough to reach the fuse box from the windscreen in most vehicles
• USB-C output at 5 V 2 A suits the current VIOFO range
• Sold in several fuse-tap types, so you can order the one that fits your car's fuse box
• Proper 3-lead ACC, B+ and GND wiring gives the camera true ignition sensing

What Could Be Better

• You must choose the right fuse-tap variant for your vehicle. Ordering the wrong style is the most common mistake here.
• It is a fuse-box install, so budget half an hour and a fuse puller, or have us fit it.
• Voltage cut-off only, with no parking timer, so it protects by battery level rather than by hours.

Why Parked Protection Needs a Hardwire Kit

Most damage to a parked car happens with nobody in it, and most dash cams cannot record then because the accessory socket cuts out with the key. A hardwire kit solves three things at once: constant power so the camera stays awake, ACC sensing so it knows you have parked, and a low-voltage cut-off so it stops before your car will not start.

Top Benefits

• Parked recording, properly: Constant power keeps motion and impact detection running while you are away.
• Battery protection you control: Four cut-off levels let you be conservative with an older battery.
• Automatic mode switching: ACC sensing moves the camera into Parking Mode the moment the ignition goes off.
• Frees your 12V socket: The cigarette lighter stays available for phone charging.
• Reaches the fuse box: 4 m of 20 AWG cable routes up the A-pillar and across without straining.
