Most CCTV quotes land on a headteacher's desk looking similar: a camera count, a resolution figure, and a price. What they rarely contain is the information you actually need to make a sound decision — the questions about storage, coverage gaps, data compliance, and what happens when something goes wrong at 11pm on a Friday. This guide covers what to look for, what to push back on, and what genuinely separates a well-specified school system from one that looks good on paper.
The first thing most suppliers lead with is resolution — 4K, HD, 2K. The numbers sound impressive, but resolution alone tells you very little about whether a system will work for your school. A 4K camera pointed at a poorly lit corridor with no consideration of lens angle or positioning delivers worse usable footage than a correctly specified 1080p camera in the right location.
What matters is the combination of resolution, field of view, lighting conditions, and the distance at which you need to identify individuals. For entrance and reception coverage where identification is critical, higher resolution earns its cost. For wide-area playground coverage, a well-placed wide-angle camera often delivers more useful situational awareness than a high-resolution unit pointed in the wrong direction.
Ask your supplier to walk you through coverage maps, not just camera specifications. If they cannot show you where the blind spots are, that is a red flag.
How long you retain footage and where it is stored matters both operationally and legally. The ICO recommends that most schools retain footage for no longer than 30 days, and that retention periods are documented and automatically enforced by the recording system — not relying on someone remembering to delete files.
On-site Network Video Recorders are standard and work well, but they introduce a single point of failure. If the NVR is damaged or stolen in a break-in, your footage from that incident is gone. Cloud recording, or a hybrid approach with offsite backup, addresses this but comes with ongoing subscription costs that need to factor into the total cost of ownership.
Ask specifically: what happens to footage retention when storage capacity is reached? Many systems overwrite the oldest footage automatically. That is usually acceptable, but you need to understand the cycle length under normal operating conditions, not the theoretical maximum.
A school CCTV system installed in isolation is a recording device. A system integrated with your access control and intruder alarm is an active security tool. When a door access event is triggered out of hours, the camera covering that entry point can be automatically flagged for review. When the intruder alarm activates, the Alarm Receiving Centre can pull live footage to verify the situation before deciding whether to dispatch.
This kind of integration does not happen automatically — it requires compatible systems, proper commissioning, and a supplier who understands how the components interact. Ask any prospective supplier to describe, in specific terms, how their proposed system integrates with your existing infrastructure.
Cameras go offline. Hard drives fail. Network switches lose connectivity. The question is not whether your system will develop a fault — it is how quickly you will know about it and how quickly it will be fixed.
A well-specified system includes health monitoring that alerts you when a camera stops recording, not just when someone notices missing footage after an incident. Your maintenance contract should specify response times and include at minimum an annual inspection. Ask what the supplier's engineer response time is for a fault affecting cameras on a main entrance — the answer tells you a great deal about what the relationship will look like in practice.
The supplier who welcomes these questions is the one worth talking to. The one who pivots straight back to the spec sheet is the one to be cautious about.
