Motion and Presence Sensors

The Presence Control Pro IR Quattro HD provides a unique square detection footprint with 4,800 switching zones and detects the presence of persons over a full 64 m2. And is also mechanically adjustable without any loss in quality. The best presence detector in its class!
Who says a ceiling-mounted presence detector always needs to have a round detection zone? After all, most rooms are square or rectangular in shape. The answer to this question comes from STEINEL. In the form of what's probably the best infrared presence detector there is on the market – the STEINEL Presence Control PRO IR Quattro HD. In a class of its own. Because – as the professional will instantly notice – the "IR Quattro HD" has a square detection zone, in other words it also covers peripheral areas, such as walls and corners. In short: there are no blind spots. The Presence Control PRO IR Quattro HD has an incredible 4,800 switching zones, giving it an extremely fine resolution that also detects extremely small movements, such as movements by people sitting. When persons are present in the room, the light stays 'ON' all the time if it's needed. Detecting presence on a maximum area of 8 x 8 metres, the IR Quattro HD provides uninterrupted coverage over 64 m2. Unique: for the first time, the detection zone is scalable on the basis of a square without any loss of quality – it is easy to adjust by means of a setscrew on the back of the unit. Benefit: absolute precision in planning usage of the presence detector in medium to large-size offices, conference and meeting rooms, classrooms and lecture theatres as well as sports halls and warehouses with a mounting height of up to 10 metres.
The high-definition presence detector is based on 20 years of expertise from the pioneer of sensor technology. At the heart of the Presence Control PRO IR Quattro HD is an ingenious combination of the precisely balanced optical system, STEINEL's own software and four digital pyro sensors. Digital technology permits optimum signal evaluation without the risk of switching errors. Ambient light level is measured by an integrated photodiode so that light is only switched 'ON' when it's actually needed. The Presence Control PRO IR Quattro HD is available in a COM1, COM1 AP, COM2 version as well as in a DIM, KNX and DALI version. A fully blown pro for professional applications.
