An infrared sensitive system which maintains an inventory of the number of occupants within a monitored room for controlling certain electronic equipment in response to the presence of occupants within the monitored room. The monitoring system activates the electronic equipment when it senses a person entering the unoccupied room, and it deactivates the electronic equipment when the last person exits the room. Switch members provide for manually resetting and overriding the control portion of the system.
