HD isn't just restricted to televisions but from now on also used in presence detectors. Because IR Quattro HD provides extremely high-definition detection. 4,800 switching zones and a square detection footprint with a presence zone covering a true 64 m² leave no margin whatsoever for inadvertent triggering and blind spots. Unique: The presence zone can be mechanically scaled without the slightest loss of quality. This means IR Quattro HD applications in medium to large-size offices, conference and meeting rooms, class rooms and lecture theatres as well as sports halls and warehouses can be planned and configured with absolute precision. Something others can only dream of.
