Under data protection laws there is a responsibility to take precautions when processing the personal data of other living individuals, including when using video and audio recording devices.
These rules do not apply if your security camera or doorbell films solely within the boundaries of your private property.
If you have a camera that just points at your private driveway, for example, or covers solely your back garden, then you do not need to worry as you won’t be capturing any other private individuals (although, it is worth considering invited visitors and guests when using these devices).
If the camera records outside that boundary, such as the street or neighbouring homes or gardens, then you do have responsibilities under the General Data Protection Regulations (GDPR). This is because you could be capturing audio and video containing other people’s private data.
Setting privacy and activation zones is also important. This can go a long way to reassuring people you’re not just a curtain twitcher on steroids.
