DCG Score & Highlights

What We Love

  • 3-wire install with colour-coded leads for quick setup.
  • Adjustable four-step voltage cut-off (11.8 V–12.4 V) guards against deep-cycle battery damage.
  • Stable Power: delivers 5 V 2 A output for demanding cameras.
  • Generous 4 m (13.1 ft) loom reaches rear glass on wagons and SUVs.
  • Highly rated by users with a solid 4.6-star average from over 950 reviews.

What Could Be Better

  • Fuse-tap set costs extra if you select the “Not Included” variant.
  • 20 AWG leads may experience minor voltage drop on very long runs.
  • TINY DIP switch for voltage cut-off adjustment instead of digital adjustments on the Dashcam itself
  • Not IP-rated – No must be mounted inside the cabin trim.

Why Hard-Wiring Matters

Hard-wiring ensures your dash cam stays active when the ignition is off, capturing unexpected incidents while the low-voltage cut-off circuit preserves your battery for reliable engine starts.

Key Benefits of the HK4 Hardwire Kit

  • Battery Guardian: Four-step cut-off stops deep discharge and extends battery life.
  • Enables Parking Mode: Automatically switches to parking mode when engine is off.
  • Universal Fit: Works in both 12 V and 24 V systems—ideal for cars, 4WDs, vans and light trucks.
  • Clean Install: 4 m harness for discreet routing and free cigarette socket space for charging.

Product Details

The VIOFO HK4 Hardwire Kit converts 12–24 V DC to a dash cam-friendly 5 V 2 A output. It constantly monitors battery voltage with a discreet DIP switch to select your cut-off threshold and uses the ACC trigger line to activate parking mode when parked.

FAQ

  • Q: Will it fit my dash cam?
    A: If your VIOFO cam has a USB-C power port (e.g. A119 Mini 2, A229 series, T130, A329, WM1), the HK4 is the official match. For older Mini-USB models, see the HK3 kit.
  • Q: Does it work with dash-cam battery packs?
    A: Yes—set the cut-off to the lowest voltage or bypass it to let your battery pack drain fully without interruption.
  • Q: How do I prevent battery drain during long holidays?
    A: Flick the cut-off to 12.4 V or remove the 2 A mini-blade fuse before leaving. Re-insert the fuse on return to restore power.
