There isn’t the resources to watch all of this cctv. Sure someone could spend weeks watching all the feeds in the city to track the thief down. But the cost quickly exceeds the value of the bike.
Something that’s changing with computer video and AI powered video search tools. I’m very in two minds about it. Being able to solve bike thefts would be great, but a lot of evil could come from a system that actually can monitor and sort through all this video.
What do you mean? Pulling a few camera feeds to track down or identify a theft occurring at a known location at a roughly known time is a few minute's work. It's worth the value of the bike let alone the value of prosecuting a criminal.
