A useful CCTV brief should define the purpose of each camera, the difference between recording and active monitoring, who handles an alert, and what happens next. It should also cover privacy, footage access, retention, maintenance and the limits of the system. These decisions matter more than a camera count.

For a facilities manager in Watford, the brief is a way to compare proposals for an office, warehouse or other commercial property. The right design depends on the site and its risks. CCTV can support a wider security plan, but a recording alone does not arrange a response.

1. State the job the system must do

List the outcomes you need: observing agreed entrances, reviewing an incident, checking an alarm, or supporting an authorised response. Identify the areas in scope without publishing a map of weak points. Ask the supplier to explain what the proposed views can and cannot show under the lighting and operating conditions at your site.

Separate an operational requirement from a sales claim. “Provide usable footage of the agreed vehicle entrance” is testable; “complete protection” is not. Consider physical barriers, access control and staff procedures alongside cameras rather than expecting video to solve every problem.

2. Distinguish recording from monitoring

Recording stores footage for later review. Monitoring requires a defined person or team to assess live pictures or alerts and follow an agreed process. Ask whether the proposal includes live viewing, event-based review, or recording only; the hours and triggers; how false alerts are handled; and who is authorised to contact the site or emergency services. Do not assume that a camera, an app notification or a “monitored” label provides a particular response.

If contracted operators will use CCTV to identify people or monitor their activities for security purposes, check the applicable SIA licensing rules for the actual duties. Verify relevant individual licences where required rather than assuming a company description settles the question.

3. Agree camera coverage with privacy in mind

Walk the proposed coverage with the site owner and relevant people before installation. Check whether the view is proportionate to the stated purpose and whether it unnecessarily captures neighbouring premises, public areas or spaces where people expect greater privacy. The ICO’s CCTV guidance for organisations advises checking camera angles and putting up signs before using a system.

Decide who is responsible for the privacy notice and signs, who controls the footage, and how requests to see footage will be handled. If audio is proposed, assess it separately: it can be more intrusive and should never be treated as a default extra.

4. Set footage access and retention rules

Name the roles that may view, export or share footage, and record when an export is made. Protect accounts and exported files, and remove access when a person no longer needs it. Agree a retention period based on the purpose and documented need, with a way to preserve relevant footage when an incident requires it. The ICO explains that UK data protection law does not set one universal minimum or maximum CCTV retention period.

5. Specify the alert and maintenance workflow

For each alert type, agree the first reviewer, the criteria for escalation, current contact details and a backup contact. State who records the decision and closes the incident. A site-specific procedure should also cover faults, loss of connection, obstructed views, changes in lighting and periodic checks that recording and alert delivery still work. Set a review date when the building layout, tenancy or use changes.

Questions to take into a supplier meeting

• What precise purpose does each proposed camera serve?
• Is this recording only, event review or live monitoring, and during which agreed hours?
• Who can access footage and who decides when it may be shared?
• What is the retention rule and how is an incident clip preserved?
• What happens when an alert or system fault is detected?
• How will the agreed views, alerts and handover process be tested?
