Steinel Presence Control System

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 meters, 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 meters.

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 pyro sensors. Ambient light level is measured by an integrated photodiode so that light is only switched 'ON' when it's actually needed.  Want to know more?  Reach out to Bell & McCoy Lighting and Controls at 972-406-8700 or visit

Control Solutions - LSI Virticus

LSI Virticus products and services enable you to reduce energy and maintenance costs by 30-50% by utilizing our communication and control system that enables the management of lights individually and collectively. Our solution scales economically from 10 lights in a church parking lot to 10,000,000 lights managed by a city. Today, outdoor lighting is largely managed through photocells or timers, which does not give property managers enough control over lighting to minimize energy costs while ensuring safety. LSI Virticus provides a very fine level of control over your lighting network, enabling you to clearly define your lighting needs relative to the costs to attain them.
