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.
Could be a motion detector for other chained lights or security. Could also be an infrared directional camera, as others have noted.
In the interest of giving more info…I wouldn’t put a motion detector there cause it’s between two houses, there’s a walkway on our side and you couldn’t get much more than a pack cigs between the fence and their house on their side.
Doesn’t mean it’s not though…
Could be a microwave proximity sensor, their like x-ray cat. Can see through wooden doors & can see criminals on the other side.
