You could put a sign in your window that reads something like: “Move your camera elsewhere.”

I like that one.

I’d get a decent laser and let that sensor get a hole burned in it. But there could be legal things involved.

My jerk neighbor does his spying the old fashioned way. He looks down from a second story window through the blinds.

All he can see on my side is the carport.

Lucianne Goldberg did this when Michael Moore attempted to spy into her window (what a creep!) After she scotch-taped an offensive message to him on the window, he took it down pronto.

Excellent thinking, Slyfox!
