They are really easy to fit yourself.

 

No they don't work on electric cars because they are steam powered

 

Did they explain what the difference is? Surely there is none, the camera just get's wired to the power outlet, like any other car. Halfords are talking nonsense.

Have a google for professional dashcam fitters in your county. There are loads of companies that specialise in fitting this kind of stuff.

 

There are lots of YouTube videos on dashcam fitting. It is really easy, and if you don't want to mess with fuse boxes and permanent wiring, just use the cigarette lighter socket. Most come with an adapter for that anyway. The wires easily slip under the roof lining between screen and lining and down the A pillar, usually just under the lip of the door rubber. It'll take you less than an hour.

 

The 17yr old at Halfords was being an idiot.

All EV still have 12V circuits that run the lights, heaters, windows etc. That's the system that you are tapping into, not the 400V system that drives the traction motor.

Find your fuse box, identify an ignition-on fuse, insert fuse-tap (which comes with Nextbase camera these days), identify metallic chassis earth and connect negative wire (bolt usually), plug camera positive wire in (secure properly with electrical tape), run cable out of fuse box and around dash and windscreen.

 

Buy a hardwiring kit from Amazon (you can get them for about £12), and get yourself on YouTube/Google. They're really simple to fit, and loads of instructions and videos available.

As the poster above pointed out, make sure you select the right fuse. I went for the cigarette lighter (look in your manual for the right number to take the power from).
