We have CCTV around our house all of which complied with the law and does not cover any public spaces or neighbours .
When we installed it over our back gate our neighbour did ask what it covered and we were happy to explain it just covered our back gate only l we installed this as we used to have a lot of deliveries and one company wrecked our back gate by forcing a delivery through we also find it helpful as a deterrent
We have a ring doorbell and cameras over our back garden , none of which intrude over neighbors.
I would approach your neighbour with your concerns as he cannot have a camera overlooking your property.
