why is it MOST shops cctv is crap and you can't make out anything they look like lego heads.
Many shops fit really basic cctv
to comply with their insurance, and then never check it or even refocus it again, some are still using tape rather than digital, so you have tapes that have been used over and over and over again.
The other problem is storage, if you have a dozen cameras each taking high resolution images, that's a LOT of memory, and then if you keep it for a time you're using a lot of hard drive space. Depending on the shop the footage can be kept for days, weeks, months, I know some places that work on a 15 MONTH cycle, so now and again when you blow an image up you're going to get Ms Lego Head.
