[QUOTE="StarDust4Ever, post: 89842, member: 3033"] One thing to bear in mind, is that affordable high definition camera technology didn't exist until a few years ago. Before 2006, HD telivisions were almost non-existant. Even after HD sets came out, most HD cameras still cost thousands of dollars. Hard drives were not large enough to store tens of hours of video, and as late as 2004, it was still standard to use a VHS capture system with 4 cameras multiplexed into a single SD screen. Typically, the VHS tapes were recycled hundreds of times so the tape quality was often severely degraded. Plus, the cameras used night vision tech even during daylight, and the grayscale images did not give any indication of what colors suspects were wearing. On some IR systems, you can't even tell if a suspect is black or white. Fast forward to 2010 and beyond, and you have 1080p or greater HD surveillance systems that capture in full color daylight + IR night vision, and mutliterabyte hard drives and highly efficient video codecs, allowing weeks worth of HD surveillance footage to be stored. Some cameras are also capable of snapping high resolution photos at a slower frame rate. Even so, the cameras are often zoomed all the way out to yield the largest field of view possible, and as such suspects in distant areas (such as a crime committed across the street) still may not be discernible. Some municipalities have even considered installing cameras on lightpolls in crime-ridden areas, although there is usually an outcry from the populous that "always on" public surveillance is a violation of privacy rights, which opens another can of worms entirely.
