Store security cameras
How come the security cameras in stores are such bad quality? You see some footage on the news about an armed robbery or something and it's black and white, all grainy and skips and jumps, is in fast forward or has every second frame skipped. You can hardly make out anything in the video.
Why aren't they good quality, like a normal video camera? Is it because the space needed to store such high quality (I'd have thought average quality) images is too much? Or has it got to do with privacy, having people unrecognizable to preserve their privacy if they're just going about their business?
