About the Viofo HK6-A
From our tech experts at CEN
A hardwire kit is what turns a dash cam into a parking camera. It draws a permanent feed from the fuse box, keeps the 12V socket free, and includes a voltage cutoff that shuts the camera down before your battery is affected.
Who it suits
A149 Pro and A149 Pro Duo owners adding parking mode.
Our tech experts advise
Set the voltage cutoff higher if the car is used only at weekends, so the battery is protected between trips. If you would rather not take the trim off and probe the fuse box yourself, we fit hardwire kits at our Beeston workshop alongside a camera install. See dash cam installation.

Frequently Asked Questions
Q: Is this accessory compatible with my dash cam?
A: Dash cam accessories are generally model-specific. The compatible camera models are listed in the product description, and you can contact CEN to confirm compatibility before ordering.
Q: What does a hardwire kit do?
A: A hardwire kit powers your dash cam directly from the vehicle's fusebox, hiding the cable and enabling parking mode. Kits include battery protection so your car battery is never drained below a safe level.
