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.
Wild guess here. Looks like the downspout and gutter are also painted matte black, perhaps they had a discount painter paint everything they saw as an external fixture.
Doesn’t look like a camera to me though. Looks more like a very large electronic weather sensor.
