Motion sensors have long since become more than simple switches: they detect precise movements in real time and enable demand-based control of light, heating or security systems. High-frequency sensors detect movement even through walls, while infrared technology reacts particularly reliably to changes in temperature. Thanks to advanced technologies such as built-in mirror optics or digital adjustability, even complex room structures and large outdoor areas can be seamlessly monitored. This not only reduces energy consumption, but also significantly increases comfort and security in and around buildings.
