About the Viofo HK6-F
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
T330 and T340 owners, including fleet and commercial vehicles where the camera needs to keep recording while the vehicle is parked or loading.
Our tech experts advise
On a van or truck the fuse box is often less accessible than a car, so allow more time for fitting. 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.
Q: Why would I add a dash cam battery pack?
A: A battery pack powers parking mode for longer periods without drawing on your car battery at all. It charges while you drive and is the recommended option for extended parking protection.

A: Yes. CEN offers professional dash cam and accessory installation from our Nottingham premises. Contact us to book.
