What is public space surveillance?
Public space surveillance is operating CCTV to monitor public space in a way that identifies or records individuals. It is a licensable activity distinct from guarding.

</figure>The trigger is proactive, targeted monitoring of people rather than the presence of cameras. Cameras nobody watches, or footage reviewed after an incident, sit differently from someone actively following individuals on a screen.
It gets added to guarding roles informally — an officer asked to watch the monitors during quiet periods — which moves them into licensable activity nobody decided to authorise.
Data protection obligations run alongside and are not satisfied by the licence. What is recorded, how long it is kept and who may see it are governed separately.
In practice
A shopping centre control room with a new operator.
She is shown the joystick, the recording system and where the incident log is. Nobody tells her what the system is for, so when a shop manager asks her to see what time a member of staff arrived, she looks.
The request is reasonable, the footage exists, and the viewing is outside the purpose the system was installed and signed for. It is also now invisible, because the log records incidents rather than viewings.
What makes a surveillance system defensible is being able to show who looked, when and why — and most operators cannot show any of it.
What goes wrong in practice
- Monitoring duties added to a guarding role with no licence check.
- Licence held while the data protection obligations are entirely unaddressed.
- Assuming a private site takes the activity outside the licence when the space monitored is public.
