Anyone know any specific about this device? I cannot find a manufacturer or anything.

Its about 0.5m wide, and maybe half that thick.

There are wifi AP’s also, and a few cameras in the store. But there are more of these dishes than cameras and AP’s combined.

I know stores do bluetooth tracking through stores, but this device is way to big for that. Also wifi makes little sense given the AP’s elsewhere. High powered RFID for monitoring pieces of merchandise maybe?
