I don't see how her vision could be impaired by looking at film of a pointer.
I love the poster of "my neighbor is filming me... post your thoughts here" and the one of your friends with gear dressed in black, but I would station one all over my property at different times of day and night with different gear. A guy with a camera in the morning at the fence, a lady on the roof with binoculars and a notepad, a young man just sitting in the middle of the front yard with a listening device pointed at her house not even trying to hide it..... too much fun.
