The Quattro HD is a high definition sensor from Steinel Sensors with four digital pyro heads behind the lens to control lighting in offices.
The sensor radiates 4800 switching zones to an area, so it will pick up the smallest of movements. With a presence detection of 8m x 8m and an overall detection area of 20m x 20m it is suited for larger office spaces.
The Quattro delivers a square detection zone that means all areas of a room are covered, even into the corners.
The detection range of the sensor can be mechanically scaled back to suit the size of the room. In IQ mode the sensor will continuously scan and learn the usage of a room, dynamically adjusting the run-on time to suit the users requirements.
This ensures that the lights are only on when required and when the room is vacant, the sensor will read this and reduce the run-on time to suit and turn off the lighting, saving power and money.
With the built in lux detection from 10-1000lux the sensor can also manage ambient light levels for light harvesting.
