Sensor Switch Wide View Sensor WV PDT 16 R Classrooms are the ideal application for the WV PDT 16 Dual Technology Wide View Sensor. Installed in the corner of the room along the entrance wall, this inconspicuous sensor provides line of sight PIR detection of small movements up to 40 ft (12.19 m) away, and combines overlapping Micro-phonics for detection around obstructions. Many classrooms are filled with shelving, projects, or lab benches.

So I got this from an older Agema Thermal Camera Setup, and it's a mirror about the size of a dime I guess, mounted on a thin pole with a motor below it and a sensor or laser behind it. Someone is bound to know what it is so I'll leave it at that. The mirror has only a couple of light hairline sized scratches from what I can tell, and if the unit ends up not working the buyer can return it.
