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.

Could be a microwave proximity sensor, their like x-ray cat. Can see through wooden doors & can see criminals on the other side.
