100m Invisible Infrared Beam Sensor Waterproof Outdoor IR Alarm

Protect your space with a silent, invisible barrier that detects movement instantly. This 100m infrared beam sensor creates a reliable perimeter that alerts you the moment the beam is interrupted.

Built for outdoor use, it keeps working through rain, glare, and harsh conditions so you stay aware and in control at all times.

Reliable perimeter protection in any environment

✅ Detects movement across distances up to 100 meters for wide-area coverage

✅ Maintains accuracy in bright light with anti-glare support up to 50,000 LUX

✅ Stays operational in rain, fog, and dust with sealed weather-resistant design

✅ Adjusts sensitivity automatically in poor weather for consistent detection

✅ Filters interference with anti-RFI/EMI design for stable performance

✅ Flexible setup with adjustable beam timing and optical alignment

This system uses an active infrared beam between a transmitter and receiver. When something crosses the beam, it triggers an alarm signal through its relay output. The digital pulse technology improves signal clarity while filtering out false triggers from environmental noise.

Installation is straightforward with adjustable horizontal and vertical angles, making alignment faster and more precise. The high-power transmitter and receiver maintain strong signal performance even across longer distances.

Its sealed housing protects internal components from rain, fog, and dust, while built-in lightning and interference protection keeps the system stable. This makes it suitable for outdoor perimeters, driveways, entry points, or property boundaries.

Compared to basic motion sensors, this beam system provides a clear, controlled detection line with fewer false alarms and better reliability in changing environments.

Creates a precise invisible barrier for reliable perimeter detection.
