We had a council lamp post cctv put up to tackle crime a few years ago but they say it cost £5000 and they haven’t got many to move about, so you only get it for a few months.
As I live in the wildwest, I have CCTV coverage all round my house. At least twice a year I get the feds round asking to look at the footage and I then send them clips via a secure portal.Mainly vandalism and car theft, but a couple of months ago had a bloke outside on the phone clearly dscussing how he'd stabbed someone. They were very interested on that and had to provide statements as well as the footage.
