The question is then when it spills onto the roadway. For example, many people will have a CCTV camera on the front of their business or even a doorbell that has CCTV on it, which covers their area but may flow out onto the street and may also cover part of the public area. This has been tested under European law. It is acceptable, if it is not the primary focus of the camera, that it is picking up things that are just outside of someone's curtilage. I am happy to discuss that with the Deputy in more detail. My understanding is people can put a CCTV system on their own land.
