The Chilli cam are cheap and cheerful, the 1080p one is absolutely useless at night though, cant capture faces within a vehicle during the day and mine now struggles with number plates after 4 years of use
I did message Chilli cam asking if the the new 4k version was any better and got no reply from them (not the first time that has happened)
The Ghost XL camera is worth a look, bigger than the Chilli cam but better quality, very popluar with motorbikers
You say you are not going to upload videos etc… if you capture a close pass, people drving on the wrong side of the road coming towards you whilst they are over taking, basically driving like a **** and they could cost someone thier life etc.. then please upload them to your County’s police Snap initiative
Ive uploaded a few it only takes a few mins, hopefully a letter from the police or even some re eductation and a fine may stop some drivers from doing stupid close passes next time and not put someone elses life at risk
