Quite some time ago I bought a cheapo dashcam, I think it was about £15 or so on ebay or whatever. It was sort of ok, but plugging into the fag lighter soket was a pain, and it was pretty big slapped onto the windscreen. After the novelty wore off I couldn't be arsed with it.
However things have moved on quite a bit, and also with "cash for crash", compensation culture, and generally stilll a lot of idiots around, both police and insurance companies seem to be taking dashcam video much more seriously.
So, a visit to local Halfords has resulted in me getting another one. Too soon for me to comment on the camera, but I was very impressed with Halfords. I went for a Nextbase 412GW with the option of Halfords putting in hardwiring for an extra £30. So, unit + Installation + SD Card £152 Total. The Halfords guys actually seemed to know what they were talking about, all nicely tucked behind the mirror, no cables, quick and easy removal.
I note that the video file format is .mov. I didn't think that was used much anymore. File size is huge, but the definition is fairly high at 1440P. The guy reckons that the 16Gb card will do 2 hours recording. I very much doubt this. I may use a bigger card at some stage.
When I have some interesting video and somewhere to host it, I'll post as questions about Dashcam crop up here now and again.
