I assume the camera is NOT on your property? Have you thought about calling the police and filing a formal complaint? What about putting something on your property that blocks the view. Or point some spotlights / IR lights at it to blind it.
Either way you may want to call the police. I know it's not illegal to record your neighbors property if the intent is to record yours and some of theirs in in your view, but I'm not sure if it's legal to patently record your neighbors.
Call the police, report it on Facebook and that neighbors website (I forgot what it's called), knock on some of your neighbors doors and tell them what you are dealing with. This is stalker'ish
