Looks like it'd be pretty easy to modify one, but not sure if the results would be worth it?
I can see myself destroying a cheap and nasty one to find out.

I wouldn't bother. Even expensive CCTV cameras employing IR can only see basic figures and faces up to 10m. Add a reflective surface and you'll find it incredibly hard to decipher characters on the plate. You would require a serious sensor and cheap portable cameras just won't cope.
It'll pick the car up though.
But with the 808 #16 A? Lens. you might get one frame just before impact. Juggled brightness and contrast in VLC.
Just kidding, pulled up behind me at the lights. Yes I actually stopped.
This is the same vehicle going past after the lights. Add movement and you don't have a hope. No amount of tweaking or magnification would give me a plate.
PS that's a helmet mounted 808 D Lens
I guess the moment before impact is all ya need?
Anyway, what I'm thinking is a modified camera plus an IR spotlight, to kinda replicate this type of thing:

Claims to have 50m range etc.
Could have 1 x Visual spectrum spotlight (many good ones around) plus 1 x IR spotlight (similar price at Jaycar) plus the modified night camera with the IR blocker removed, and a visible spectrum filter in for the benefit of the IR?
Dunno, anyway still learning about this stuff. Will let y'all know how it goes.
