You can use CCTV, but it must be justified
You can use CCTV as long as you have a ‘lawful basis’ for processing personal data. This is a requirement under the UK GDPR.
The 2 lawful bases that are most appropriate are:
- Public task: if you need to use CCTV to allow you to carry out your official duties
- Legitimate interests: if you need to take or use CCTV because you or a third party has legitimate interests
Consent is not an appropriate lawful basis for CCTV because it's:
- Unlikely that you'll be able to obtain consent from every person who may be recorded on CCTV
- Very difficult for people to opt out of
This is explained in the DfE's guidance on using CCTV in schools.
If you're using CCTV for the first time, you should carry out a DPIA
