Why do CCTV cameras always have extremely poor resolution?

Question

I can’t think of a reason why other than the cost but surely it’s worth the potential to solve more crime

Answer 1

In addition to the storage consideration and trying to balance resolution/storage/cost, you generally try to have a mix in a good system. You have cameras positioned to capture the general activity (e.g just generally monitoring the car park, or being able to see what’s going on in the back yard). You then have higher resolution cameras trying to catch more detail at key points such as for cars coming into a property, near doors etc. that way you hopefully can get the ‘big picture’ of what’s going on and capture sufficient detail on one of the higher resolution cameras to capture an image that’s good enough for identification. The camera zone should generally overlap a little so you can track the activity from one camera to the next.
