Adding AI analytics to CCTV should begin with an audit, not a camera replacement quote. Many existing IP cameras can support intelligent detection, but only when the views, image quality, network and response process are suitable for the intended use case.
Use this CCTV audit checklist to identify what can be retained, what needs adjustment and where a targeted upgrade may be justified.
1. Define the outcome before auditing equipment
Write down the security or operational question the system must answer. Examples include after-hours intrusion, perimeter activity, vehicle movement, loitering, people counting, queue pressure, staff presence or access to a restricted area.
- Is the required event clearly defined?
- Which zones, schedules and camera views matter?
- What should happen when the event is detected?
- How will success be measured during a pilot?
A clear use case prevents the project from becoming a collection of generic alerts.
2. Check the camera inventory
- Record each camera’s make, model, resolution and location.
- Confirm whether the cameras are IP, analogue through an encoder, or part of a closed proprietary system.
- Identify which cameras provide accessible video streams.
- Note any cameras already offline, unstable or due for replacement.
- Mark the high-risk and high-value views that should be prioritised first.
Not every camera needs AI. A focused rollout on the most important views is often more effective than enabling analytics everywhere.
3. Review image quality
An image can look acceptable for general viewing but still be unsuitable for analytics. Review the actual recorded and live streams rather than relying only on the camera specification.
- Can people, vehicles or objects be distinguished at the required distance?
- Is the image sharp enough during movement?
- Does compression create blocking or blur?
- Is the resolution appropriate for the chosen analytic?
- Does the image remain usable in poor weather or changing light?
4. Test night and low-light performance
- Review the camera after dark, not only during the day.
- Check for glare from lights, headlights or reflective surfaces.
- Confirm that infrared lighting does not wash out the target area.
- Look for dark zones where people or vehicles disappear from view.
- Check whether insects, rain or vegetation create repeated motion events.
Night performance is especially important for after-hours monitoring and perimeter detection.
5. Assess camera positioning and field of view
- Is the target area visible without major obstructions?
- Is the camera angle too steep, too wide or too distant?
- Does the view include unnecessary movement that may create noise?
- Are entrances, gates and restricted zones covered from the correct direction?
- Can adjacent cameras provide context if an event moves across the site?
Repositioning a suitable camera can sometimes deliver more value than replacing it.
6. Check frame rate and stream settings
- Confirm the available main and sub-stream resolutions.
- Review frame rate, bitrate and compression settings.
- Check whether the analytics platform can access the required stream reliably.
- Confirm that time stamps are accurate and synchronised across cameras and recorders.
- Test whether stream changes affect recording or remote viewing.
7. Audit the recorder or VMS
- Record the NVR, DVR or VMS make, version and licence status.
- Confirm how third-party integrations are supported.
- Check whether camera names and channel assignments are consistent.
- Review user permissions and remote-access controls.
- Confirm recording retention and whether footage can be exported when required.
For multi-site businesses, consistent naming and configuration make monitoring, incident review and reporting much easier.
8. Review network and internet stability
- Check local network capacity and switch health.
- Identify cameras with packet loss, unstable streams or frequent disconnects.
- Confirm available upload bandwidth for offsite monitoring.
- Review firewall, VPN and secure remote-access requirements.
- Separate critical camera traffic where network congestion is a risk.
- Test how the system behaves during an internet outage.
AI performance and control-room verification both depend on reliable video delivery.
9. Check power resilience
- Identify which cameras, switches, recorders and routers have backup power.
- Confirm expected runtime during an outage.
- Review surge protection and power-quality issues.
- Check whether the monitoring team is notified when equipment goes offline.
A camera network cannot provide useful alerts if the supporting network and power infrastructure fail at the same time.
10. Review camera health monitoring
- Can the system detect offline cameras or lost video?
- Are faults assigned and tracked until resolved?
- Are critical cameras prioritised?
- Does anyone review obstructed, moved or degraded views?
- Is there a clear maintenance and escalation process?

11. Confirm the alert and response workflow
- Who receives and verifies an AI event?
- Which events require escalation?
- Who must be contacted and in what order?
- What happens when a contact is unavailable?
- Which response resources are available for the site?
- How are authorised after-hours movements handled?
- How will incidents be recorded and reported?
See what happens after an AI CCTV alert for the full operational workflow.
12. Review privacy, access and data handling
- Limit system access to authorised users.
- Review where footage and incident records are stored.
- Confirm retention requirements and access logs.
- Use analytics that are appropriate for the site and purpose.
- Ensure notices, policies and procedures reflect the way the system is used.
13. Plan a controlled proof of concept
Before a large rollout, test the use case on a representative group of cameras. Agree on the detection rules, operating hours, expected event types, false-alert review process and success measures.
- Choose cameras with suitable and unsuitable conditions for comparison.
- Track missed events and irrelevant alerts.
- Measure operator workload and response clarity.
- Record any camera, network or process changes required.
- Use the results to define the wider rollout.
Turn the checklist into a practical upgrade plan
The audit should end with a clear list of cameras that can be retained, views that need repositioning, infrastructure that requires attention and analytics that can be tested first.
