Advocates of CCTV video surveillance emphasize the technology's value in quickly apprehending criminals. Two recent well publicized events confirm this point. In mid-February 1996, the UK media broadcast a harrowing set of pictures taken in a shopping centre in Bootle, near Liverpool, and outside a builder's yard less than a mile away. They showed the grainy images of a small child being led away by two youths. Two-year old James Bulger, who had wandered from his mother's side in the shopping centre, was later found murdered. The second case involved a terrorist bombing.

Surveillance video originally relied on video cassette recorders (VCR) to store video on VHS tapes, but most users larger than a convenience store have moved on to digital recording. Digital video recorders (DVR) that digitize and compress the analog video before storing it on a hard drive offer much more flexibility than VCRs — higher storage capacity, quicker search and retrieval, remote access over networks and the ability to export clips or images for analysis and sharing.

[W]orth noting is that, if public video surveillance is performed by a private entity for a public body, the relevant public-sector legislation applies. This would apply in the case of a contractor being hired to operate a public surveillance system.
