So I have this neighbor who is really causing trouble for my security setup. He shines his floodlights into my cameras and puts up tons of flags and banners, triggering my motion sensors all the time. Recently, he added a motion light that goes off with the wind whenever his banners move. The light shines directly into my window, which is really annoying. I need something like mirrored window film that can be applied on the outside of the window. The inside has textured glass, so that’s not an option. I can’t seem to find anything meant for the outside. Anyone have any ideas?
Are you sure he’s doing this on purpose? Have you talked to him? Maybe he thinks you’re pointing your cameras at his property. Maybe if you showed him what your cameras are looking at, he might understand.
As for mirror film, it usually only works during the day. At night, people can still see inside, but it gets harder to see outside.

He’s definitely doing this on purpose. He’s an old guy, not all there. I’m not worried about him seeing in. The glass is textured, like a bathroom window. I just want to block the light from my window.
@Abi
Older folks often don’t trust new tech, especially with all the conspiracy theories on TV. They probably think cameras are spying on them. You should’ve talked to him about crime in the neighborhood BEFORE setting up cameras. If you had, he might’ve been willing to watch your place for you. Most neighbors know about my cameras and ask me for info if something happens. Talking to him after you put them up was a mistake, you should always talk to your neighbors first. Your cameras might not work well at night, and you might still need your neighbors’ help.
@Rafe
I’ve read through all the comments. He’s been watching my property with his own cameras for years before I even set mine up. There’s no talking to him, he’s lost it.

Last I checked, we live in a free country. I don’t need permission from my neighbor to do things on my own property. No one should. If they’re in a bad HOA, that’s on them.

Sure, you can upset your neighbor, but now you have to deal with the fallout. 
@Luca
If there are bright lights outside and you have dark curtains inside, it should still reflect the floodlights.
What about cutting a piece of plexiglass to fit the window and spraying mirror paint on it? You could just place it inside the window frame.

That could be an option!
Black-out curtains work really well.
But hey, you should escalate this! Set up a spotlight with a motion sensor that turns on only when his light goes off, aimed right at his windows.
You could also set up a really annoying Christmas display with loud music, triggered by his motion sensor.
@Rai
The kid inside me would love to escalate, but I think a mirror would just reflect his actions without being too aggressive.

At least use multiple mirrors and really get that Archimedes heat ray effect on him.
@Rai
I’ve considered using a few disco balls.
You could use mirrored spray paint, but you might not be able to if you’re renting. Also, I’m not sure if these products block all light. You could apply a light-blocking layer first (like paint or plastic) to stop your neighbor from looking in.
Also, there’s no way to create a one-way mirror that works perfectly. The ‘one-way glass’ effect depends on which side is more brightly lit.
@Barrett
I get that, but the glass is already frosted on the inside. It’s like a bathroom window, so putting film inside won’t work. I’m not worried about him looking in, just about blocking his light and sending it back to him.
It may look rough, but tinfoil will work.
I’m curious about where your cameras are pointed and how your motion detection is set up. If his flags are triggering it, maybe the camera’s field of view or sensitivity needs adjusting. Nothing your neighbor does should affect your camera if it’s aimed at your property.
Maybe you can set motion zones or shrink the detection area while still increasing sensitivity.
@Foster
He’s put flags on his side of the fence, but they blow over to mine. I don’t want to call the cops over flags blowing across my fence, I want them to take me seriously if something worse happens.
Why not just put up a big brick wall around your house and be done with it? Peace out.
