What is CCTV?
Closed-Circuit Television, commonly known as CCTV is a sophisticated surveillance technology designed to monitor and record activities. The system uses cameras to capture real-time footage, enhancing security and providing valuable insights.
Why is CCTV important?
CCTV is crucial for security and safety across lots of different settings. By providing continuous surveillance, CCTV acts as a deterrent to potential criminals, protecting businesses, homes and public spaces. Real-time monitoring means there’s a swift response to emergencies, reducing the risk of theft, vandalism and unauthorised access. In the event of an incident, recorded footage becomes valuable evidence for investigations.
How does a CCTV camera work?
CCTV operates on a straightforward yet sophisticated principle. The fundamental components include the camera, lens, image sensor and signal transmission infrastructure. The camera's lens focuses light onto an image sensor which converts the received light into electrical signals. The camera's processing unit enhances and compresses the digital signal for efficient transmission.
The transmitted signal is then received and processed by a recording device such as a Digital Video Recorder (DVR) or Network Video Recorder (NVR). Many modern CCTV systems also incorporate advanced features like motion detection, infrared capabilities for night vision, and pan-tilt-zoom functionality.
What are the legal requirements of CCTV?
In the UK, the use of CCTV is subject to legal regulations and must comply with data protection and privacy laws. The ICO provides codes of practice and guidelines for the use of CCTV and in certain cases, organisations may be required to conduct Data Protection Impact Assessments.
When can CCTV systems be used?
CCTV systems must have a legitimate and lawful purpose, such as enhancing security or preventing crime. Individuals must be informed about the presence of CCTV cameras with clear and visible notices and excessive surveillance may be considered a breach of privacy.
Access to CCTV footage should be restricted to authorised personnel, however individuals have the right to request access to footage that involves them, as well as the right to request the correction of inaccurate footage.
