I have one in my van, its a DVR 005 or something but no matter as its out of date/unavailable.
Like many it came with an awful multi-jointed huge suction cup affair, but as my van has a bulkhead I removed the rear view mirror and drilled the mirror bracket to allow the camera to bolt directly on to it. Much more discreet, and the last thing I’d want is to get broken into as something thinks its something worth taking.
Over the last couple of years its captured people stopping on railway crossings as the gates come down, driving down grass verges to beat queues, road rage amongst other drivers, a pheasant launched directly at me by an oncoming lorry, a cyclist over shooting a junction into my path and thankfully choosing to crash into a signpost rather than me (must find that clip, sure I’ve got it somewhere!) and someone who pulled out directly across me who had somehow managed to miss my huge van that had been clearly visible for quite some time.
Last week I stopped behind a queue of traffic and left space for a car pulling out of a school, the driver was distracted and when s/he realised and pulled out, the traffic had started moving again and the car coming the other way slithered past near the kerb and missed the rear bumper by about 12 inches. It was torrential rain and if they’d had hit each other I’d have probably been hit too…I was really glad I’d just stopped and waited, and not flashed or gestured to anyone to go.
