Passive infrared sensors react to the infrared radiation emitted by warm objects such as the human body. Without generating radiation themselves, they detect changes in the infrared radiation in their environment and thus recognise moving heat sources.
It can even see through thin walls. HF sensors emit high-frequency waves and receive the reflected signals from objects. By analysing these reflected waves, they can determine the distance and movement of objects. The high-frequency sensors are even able to penetrate certain materials, such as glass or lightweight walls.
Fills the entire space and also detects around objects. Ultrasonic sensors work by emitting ultrasonic waves and receiving the waves reflected from objects. The time it takes for the waves to travel from the sensor to the object and back is measured and used to calculate the distance or to detect objects.
Detects only people and can also count them. With "Human Presence Detection", we have achieved a quantum leap in the field of sensor technology. The result is a presence detector that not only detects people who are present, but also counts them. The innovative technology is based on highly sensitive optics combined with mathematical algorithms.
The world's first true presence detector. True Presence® technology is based on the finest high-frequency measurements of the environment. The presence of people is detected using three-dimensional breathing patterns. The combination of an extremely sensitive antenna and unique sensor software ensures that the presence of people is detected 100%.
The basic answers for building and room use. Infrared matrix technology is based on a grid principle in which the detection area is divided into individual fields. Each of these zones is analysed in detail so that movements, the number of people and other detection variables can be precisely recorded in each field – without a camera.
