I only have one neighbor. He wanted me to monitor his property (which I do not do). Basically, you need to indicate video surveillance at the property entrance (signs...), you are not allowed to record public spaces or neighbors. We have multiple overlapping surveillance. Fixed and also swivel cameras. Normally it works like this: if a neighbor has questions, you show them a screenshot or live image. Either the camera is directed so that only your property is shown or it is masked out by software. Of course, he has to trust that nothing changes. In extreme cases (mostly involving court proceedings) there have been individual cases where a privacy screen/cover was ordered for the camera. However, I do not know of any private cases. Do you think about it in advance? Just wait and see how the neighbors react...
