I work for a company that makes security cameras and we also make radars as a supplement to the cameras. The purpose of the radar is to tell PTZ cameras where objects are so they can pan/rotate to the correct spot as quickly as possible.
In this case these look like fixed cameras so I don’t think it’s a radar.
I would assume, considering the climate these cameras are in that this is some kind of weather sensor.
Considering the size of it, it probably has a few features to it.
Yeah it’s quite hard to tell. The shape is kinda generic so anything could be behind all that plastic!
