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.
Just about everyone one of these that I’ve seen is just slapped straight on the front of a house pointing straight at the street. I imagine most people don’t bother even looking at footage that doesn’t have someone suspicious approaching the door but other will be.
It seems like an odd interpretation of GDPR in the article and the one case it cited has a LOT of other factors. How can it be someone’s private information if it was only captured in public? If someone goes walking down the street yelling information or displaying it openly, it is no longer private information
