    They are also IR controlled. A lot of them have a little window on the front of the unit, and an array of transmitters in the ceiling.

      Probably different models for different sets. The set I work with are purely wifi. They have a light on them to blink is the only extra thing they do

      IR on them does sound stupid though, in a store environment that can be blocked rather easily
