Camera multisensor technology. The future is within reach. For over 5 years, the world's leading specialists and universities have been developing this system, where image analysis takes place directly in the sensor. With the HPD2 – HPD stands for "Human Presence Detection" – STEINEL achieves a quantum leap in the field of sensor technology. The HPD2 is the world's first presence detector that not only detects present individuals but also counts them, regardless of whether they are moving or not. The heart of the person sensor is an innovative camera technology with a highly sensitive optical system, combined with a complex mathematical algorithm. Additionally, the HPD2 features integrated temperature and humidity sensors, opening up entirely new possibilities for building automation. Lighting, heating, and air conditioning can finally be controlled according to the number of people present in a room.
