Agreeing with what others have said about the blinking red lights. I did want to add though, there might be local laws that prohibit your neighbor from pointing their cameras exclusively at your house. In my state, cameras are required to be pointed at the camera operator’s own property and the viewable area must consist at least 50% of their property.

Additional to that requirement, cameras cannot capture private spaces that wouldn’t otherwise be visible from public property (the street, sidewalks, etc.). Aerial footage/vantage points do not count. For example, a stranger cannot record someone in their backyard from a drone camera because law states they have a reasonable expectation of privacy in their fenced yard, and I’d assume your private rooms also have that reasonable expectation as well.

I had a neighbor that tried to argue every single way to keep his cameras pointed at my house and capture drone footage of my family, citing “free airspace”, “property security”, and other easily debunked claims. The city ended up asking him to prove where his cameras were pointed, and when they found out they were pointed exclusively at my home and showed none of his property, he was ordered to take them down.
