Got CCTV - do you need a sign - the law

Faced with the threat of criminal activity such as burglary and vandalism, increasing numbers of property owners and businesses are installing CCTV systems to provide a constant watchful eye over their homes or premises. CCTV can act as a deterrent, warning would-be criminals that their actions will be monitored and recorded, and can provide the police with vital evidence to assist in the arrest and prosecution of offenders. However, it is worth knowing that anyone who installs CCTV may have legal responsibilities to display warning signs that are easily seen.
