Steinel accessories feature a selection of power packs.
Steinel Occupancy sensors are a way to control the lights in a room without having to flip a switch. They are usually installed to a ceiling and once they detect any movement the lights will turn on. This is a great way to save money and energy.
Steinel presence detectors are another form of infrared detection. They do require that you manually turn the lights on but they will turn off the lights if there is no longer any movement in the room. These detectors also have audible sounds to warn the user that it is about to turn off.
