What is this black thing, roughly the size of a coffee mug, cylindrical in shape, attached to a circular bracket, on the side of my neighbours house? Its position can be adjusted, doesn’t light up or make noise. Not sure on weight as it is fixed to the wall. We think that it’s plastic.
That’s what crossed our minds, but there’s no lens type thing on the front.
Don’t get on though, so a camera wouldn’t surprise me…they’re “well do as we like and you can get fucked” type of people.
Many things are transparent to infrared that are not transparent in optical light, especially black plastics. It could still be a camera.
Are you sure that's not just a tinted lens cover? That's what it looks like to me from your photo, anyway.
