This document offers guidance to current or potential users of CCTV on how to get the most from this technology. Much like buying a new car or a television you have to make some important decisions before you buy to ensure that it actually meets your requirements and gives you a return on your investment. Further guidance for users of CCTV is available in the Surveillance Camera Code of Practice. The code is intended to strike an appropriate balance between protecting the public and upholding civil liberties. Further information including a more comprehensive buying guide is available from the Surveillance Camera Commissioner's website.
