A CCTV and security installer is a specialist who designs, supplies and installs closed circuit television surveillance systems for homes, commercial properties and construction sites. Domestic self-monitored systems can be installed by any competent engineer, but systems connected to a monitoring centre (ARC - Alarm Receiving Centre) require the installing company to hold NSI (National Security Inspectorate) Gold or Silver approval or SSAIB approval. Commercial CCTV that captures images of members of the public requires the operator to be registered with the ICO (Information Commissioner's Office) under the Data Protection Act.

Qualifications to look for
NSI Gold or Silver approval is required for CCTV installers whose systems will be connected to an Alarm Receiving Centre for professional monitoring. NSI approved companies are audited annually against BS EN 50132 standards. Verify at nsi.org.uk.
SSAIB (Security Systems and Alarms Inspection Board) approval is an equivalent to NSI for monitored security systems. Insurance companies and police services recognise both NSI and SSAIB approved systems. Verify at ssaib.org.
Organisations operating CCTV that captures images of members of the public must register with the Information Commissioner's Office under the Data Protection Act. The installer should advise on this obligation and signage requirements.
How to find a reputable CCTV and security installer
Frequently asked questions
Do I need to register my CCTV with the ICO?
If your CCTV captures images of people in public places or neighbouring properties - which most external home CCTV does - you technically need to register with the Information Commissioner's Office (ICO) for about £40/year. Display clear signage indicating CCTV is in operation.
How many cameras do I need for a 3-bed house?
Typically 4 cameras - front door, back garden, side access and driveway cover most properties adequately. An NSI installer can advise on siting to minimise blind spots.
Can my neighbour object to my CCTV?
CCTV pointed at public areas and your own property is generally lawful. Deliberately pointing cameras to capture your neighbour's private areas without consent is not permitted under the DPA/GDPR and could constitute harassment.
