A CCTV system should be assessed as a route from a scene to useful information. The camera position, lens, lighting, recording and operator all influence whether the result meets the requirement.
Describe the task for each scene
An overview helps an operator understand activity. A more detailed view may be required to recognise a vehicle or identify a person. Give each camera a purpose and test the proposed position against it.
Include the difficult conditions
Think about darkness, glare, fast movement, weather and changing site obstructions. Review the view when the conditions are representative, not only when the installation is easiest to demonstrate.
Plan retention and retrieval
Agree the recorded detail and retention required, then consider storage and network capacity. The people using the system need an understandable way to find, review and export the relevant recording.
Control access to the system
Agree user roles, administration, remote access and the handling of credentials. Discuss the customer’s IT requirements early rather than adding an unmanaged connection at handover.
Keep the view useful
Changes to scaffolding, landscaping, lighting and site boundaries can change coverage. Include inspection and adjustment in the maintenance and project-change process.
Your planning checklist.
- Camera objectives and locations
- Day and night conditions
- Recording and retention needs
- Playback and export responsibilities
- Network and user access
- Maintenance and change review
