How to install a dash cam
If your dash cam isn't fitted properly, not only can insurers and the courts disregard the footage it captures, but you may well be breaking the law.
There are strict rules about where in-car equipment should be positioned.
Dash cams must be fitted so that they don't obstruct the drivers' vision, otherwise you could liable to pay a fine. Our expert guide will help make sure you get yours set up right first time.

Best place to mount your dash cam
A dash cam must be fitted behind the rear-view mirror so it's in the centre of your windscreen, but not obtrusive to your line of sight. This ensures it will capture both lanes of the road ahead, along with the signage on either side.
The best dash cams come with a nice long power lead, so you can tuck it around the edge of your windscreen before trailing it to the cigarette lighter. Make sure you don't simply plug it in directly, leaving the cable hanging down and getting in the way.
Mounting a dash cam isn't like setting up a hands-free holder for your smartphone or mounting a sat nav, where it's tempting to just stick it wherever works best. You absolutely cannot do this when installing a dash cam.
Different types of dash cam mount
Most dash cams come with one of two types of mount:
- double-sided tape
- or suction cup.
Double-sided tape gets lower scores in our tests, as it's so inflexible. Once you attach it to the windscreen, it's extremely difficult to reposition. You'll need a steady hand to fit it correctly and you'll have to make sure you get it in exactly the right place, first time.
Suction-cup mounts are by far the better choice. They're easier to fit, and you can reposition them as often as you like. Most we've tested stay attached with no problems - if we ever find that they refuse to stay on, we make sure we mention it in our .
Hardwire a dash cam
Hardwiring involves connecting your dash cam directly to your car's on-board electricals. This means it will start up and switch off automatically with your car's ignition, and the wires will be hidden out of sight under your dashboard - plus it frees up the cigarette lighter for other electronics.
Just about every dash cam we test can be hardwired, so if you're eyeing up a new model to purchase it should be compatible.
High-street retailers Halfords is one of the only nationwide chains to offer this service, but your local in-car radio and electronics specialist should too. What's more, it shouldn't cost you much at all - £30 or so should do it for retailers such as Halfords. Plenty of retailers also offer fitting at the point of sale, too.
Alternatively, you can do it yourself. It will involve accessing the fuse box, usually located inside or beside the glove box, and swapping a connection with your hardwiring kit.
The whole thing should take you about 20 minutes to complete. Just how complicated it is will depend on what vehicle you drive, so we'd recommend leaving it to the pros if you're not entirely confident in your skills.
