Further Information

Motion detectors 

Motion detectors are true classics among lighting control systems. However, the term is somewhat misleading, as the most common type of motion detector does not react to movements in the environment, but to changes in temperature. 

Types of motion detectors 

Depending on the application, different types of sensors are best suited: in sanitary areas it is practical if the detector also reacts through thin doors, in outdoor areas it is advantageous if not every little movement is switched. 

PIR motion detector 

Passive infrared sensors work with infrared technology and react to temperature changes in the environment. They are ideally suited for outdoor applications. 

HF motion detector 

High-frequency or radar sensors operate via electromagnetic waves. This enables them to function even through thin walls or doors. 

Ultrasonic motion detector 

Work with sound waves and are best suited for indoor use. 

Camera motion detector 

Function by means of electronic evaluation of image data and are suitable for indoor and outdoor use. 

Advantages of motion detectors 

✔ Comfort 

Switching lights manually was yesterday! Especially if the light switch cannot be reached immediately (large halls, outdoor areas) or if your hands are simply full, a motion detector makes your life much easier. 

✔ Efficiency 

Motion detectors only switch your light when necessary. This ensures high energy efficiency and thus considerable cost savings. 

✔ Security 

Light may attract mosquitoes, but it deters villains! To do this, you provide bright, automatic lighting for safe paths around your application. 

The right detection range 

Depending on the area of application, the angle of detection and the detection range of your motion detector depends on the application. Installed at entrances, a detection angle of 90° is often sufficient; 180° is recommended for house walls. When installing in the middle of the room, you should ensure a 360° detection range so that the motion detector switches the light on. No matter from which direction it detects movement. The detection range depends on the size of the areas to be equipped. In the private sector, the detection range often does not have to be as high as in the commercial use of motion detectors. After all, switching the light too frequently can be quite annoying due to the reaction to things moving in the distance. Here the rule is: try it out and adjust it accordingly. 

How long should the light stay on? 

Most motion detectors offer flexible setting options to suit your needs. In principle, the lighting duration must be sufficient for use of the illuminated application. Experience and trial and error are the motto here too. 

Motion detectors for indoors or outdoors? 

Both! In outdoor areas the safety aspect plays a primary role. Detect tripping hazards in dark corners early on and thus reduce the risk of injury. Don't even tempt burglars to do this. Motion detectors inside are clearly worthwhile because of their energy savings! Especially in rooms where the light is often "accidentally" left on, the installation of motion detectors is a worthwhile investment.
