Yes, you can use CCTV to protect your home. However, if your cameras capture images beyond your property boundary, such as a neighbour’s garden, shared areas or a public footpath, UK data protection law applies. You should be able to justify the coverage, tell people that recording is taking place, keep footage secure and only for as long as necessary, and respond to requests for footage. These rules come from UK GDPR and the Data Protection Act 2018, and if someone asks for footage of themselves (a subject access request) you normally have one month to respond. We position cameras to focus on your property and minimise capturing other people’s. The ICO’s guidance on using home CCTV systems explains your responsibilities in full.
