    They can, but it's a case of storing endless hours of high resolution video which costs too much for most users for who simply proving a crime took place is enough (insurance purposes).

    Also, please learn where and when to use the genitive case and don't confuse it with plural.

    The cctv's in town centres are pretty bad.

    After calculating the amount of storage space needed it seems quite cheap and possible. I don't know why.

    Care to share your calculations?

    EDIT: I get about 11TB for 2x weeks worth of video H.264 compressed high def.

    Now imagine a town centre's worth of this - say 20 cameras, that's now 220TB.

    EDIT: EDIT: And if you wanted enough hard drive space to store that at once, you'd need around £12,000

    There's also the pure practical issues of making a high-resolution camera that can practically see in the dark. You'd need a wide aperture lens (expensive) plus a very high-sensitivity high-resolution sensor (very expensive), making the units unaffordable. High-sensitivity low-res sensors are cheap - upscaling them to higher resolutions is where the problems start. Couple that with the storage issues, and you begin to see why it's not practical for every CCTV camera to be super high resolution.

    His calculations must be wrong.

    Facial regoc camera's and all their equipment ~ £1500
    1067 towns in UK
    say about 100 cameras in each town

    That's 1500 x 10 = 15,000 x £100 = £1,500,000

    That's for the cameras alone. About 10Mb for all image and details per person (62.2m in uk) Means 75 Terrabytes of storage. Then you have the network costs at least a million ontop then all the people running it say £6.50 hour. 40 x £6.50 = £260 per worker per week.

    Starts to get VERY expensive and as you mentions all the footage would be loads more Tb

    Who is going to trawl through hours of footage? Imo, wait until accurate facial recognition software becomes available for governments to use, and I'm not talking about the crappy software that comes preloaded with your new laptop camera, much more advanced.
