Motion Detectors and Twilight Switches for Lighting Automation
Modern lighting is no longer imaginable without smart automation. Motion and twilight sensors turn your home, office, or warehouse into an energy-efficient and safe environment. Searching for switches in the dark or a forgotten light on in the yard is now a thing of the past. However, when choosing cheap sensors from hardware stores, buyers often face a short lifespan. The relays of cheap sensors are not designed for the starting currents (inrush current) of large LED floodlights and quickly "stick" or melt. VIDEX sensors are engineered (Heavy-Duty) specifically to work with modern powerful LED lighting, guaranteeing tens of thousands of switching cycles without false alarms.
Why professionals trust VIDEX automation:
- Heavy-duty relays: Our sensors are ready to serve even massive LED industrial lamps and floodlight groups without damaging the contacts.
- Precise calibration (SENS/TIME/LUX): Unlike cheap analogs, you can perfectly precisely set the sensor's sensitivity, light duration, and darkness threshold so that the light does not turn on during the day or react to cats in the yard.
- Universal architecture: We offer both built-in sensors (which blend with the ceiling like small spotlights) and surface-mounted models for indoors and outdoors.

Q: What is the fundamental difference between infrared (PIR) and microwave (HF) motion sensors in lighting automation?
Q: Why does the maximum relay switching power differ for LED luminaires and resistive incandescent bulbs?
Q: How do VIDEX motion sensors help improve spatial energy efficiency according to modern standards?
Q: How to properly set the sensor's sensitivity (SENS) and ambient light (LUX) threshold parameters?
Q: Is it possible to connect multiple motion sensors in a single common lighting circuit?
A: PIR sensors detect changes in heat radiation (photons) within the optical line of sight. Microwave (HF) sensors actively emit 5.8 GHz radio waves and detect the Doppler shift of the reflected wave, allowing them to register motion even through thin drywall or glass.
Q: Why does the maximum relay switching power differ for LED luminaires and resistive incandescent bulbs?
A: At the moment of switching on, LED power supplies generate a sharp and powerful current pulse (Inrush Current) that can melt standard relay contacts. Therefore, a sensor with a 1200W nominal rating for incandescent bulbs can technically only handle up to a 300W total LED load.
Q: How do VIDEX motion sensors help improve spatial energy efficiency according to modern standards?
A: By automating the lighting to turn on only in the presence of a person, the human factor and the illumination of empty rooms are eliminated. Using sensors in offices, stairwells, and warehouses physically reduces electrical energy consumption by 60% to 80%.
Q: How to properly set the sensor's sensitivity (SENS) and ambient light (LUX) threshold parameters?
A: The LUX dial calibrates the photoresistor, blocking the lighting from turning on during the day when natural light exceeds the set threshold (e.g., 30 lx). The SENS dial allows mechanical reduction of the detection radius so the sensor does not react to people in adjacent rooms.
Q: Is it possible to connect multiple motion sensors in a single common lighting circuit?
A: Yes, by using parallel wiring, a single lighting line can be controlled simultaneously by two or more sensors. This is critically necessary in long corridors—as soon as any of the sensors detect motion, it closes the mains phase (L) and activates the lighting.
