CCTV is the most privacy intrusive form of data processing undertaken presenting the greatest risk to data subjects.

• CCTV should be used only to address real and serious threats to individual health and safety or the protection of property.
• CCTV should be used only as a last resort, when other less intrusive approaches have failed.

It is important to take every reasonable measure to limit the collection of personal data from innocent people and to destroy it when it is no longer required for the original purpose.

Disclosure of video images can cause mental distress, loss of dignity, and loss of rights and freedoms for innocent people.
The awareness of being filmed by a camera will alter the behaviour of individuals and can cause discomfort or stress. In any case, the mere existence of the camera will undermine personal freedom.
