The TrackVIEW IR sensor, a single ceiling-mounted IR sensor for use with the TrackVIEW IR System, allows the use of up to five additional TrackVIEW IR sensors per system. The power supply and closure are already built into the TracKVIEW system. The TrackVIEW Active IR Sensor is adjustable for precise presenter control over each IR sensing zone. Each active IR sensor is equipped with a metal mounting enclosure that can be mounted in acoustical ceiling tiles or sheetrock ceilings.
