Problem solved!
The daughter bought the same style camera with WiFi and her new boyfriend put up a pole made out of 1 3/4" plastic pipe. He mounted the camera to treated wood and attached it to the pole and placed it right next to the neighbor's camera but in my yard. Now she can't see his camera from the window and she has a great view of his rear patio. Haven't heard a peep from him yet.
Nothing illegal and nobody got hurt!
