Technical Principles
1. Dynamic Spectrum Control
Self-optimizing frequency hopping technology ensures independent channel integrity
2. Digital Signal Authentication
Unique encrypted identifiers with multi-layer verification mechanism
3. Environmental AI Compensation
Real-time adjustment of detection thresholds based on ambient analysis
Features:
1. Solitary beam detectors, also recognized as single beam sensors, find widespread use in automated sliding doors, shutter doors, garage doors, windows, and various other applications.
2. Each unit consists of a transmitter and receiver, featuring an integrated amplifier that emits an infrared beam. This narrow infrared beam (either Type I or II) effectively counteracts external light interference.
3. Even when mounted at a low elevation (20-40cm above ground level), these sensors maintain a dependable detection range spanning 2-20 meters.
4. Distinguishing itself, the IR-20 sensor boasts a self-detecting capability tailored for sliding doors. Upon interruption of the self-detecting beam, the door halts its closure, swiftly retracting to its widest position. Resuming its opening motion, the door continues until the detecting beam is reinstated. Following complete closure, the detecting beam deactivates.
Functionality:
1. Position each detector pair at opposing points, delineating an infrared zone between them. Detection of movement within this zone triggers an alarm signal relayed to the security alarm host (not provided).
2. Ideally suited for incorporation into security setups within educational institutions, commercial complexes, medical facilities, residential premises, and more.
3. The detection scope maintains consistency even amidst inclement weather scenarios like rainfall, dust storms, etc.
4. Complementing the product, an English Usage Manual accompanies the package, furnishing comprehensive guidance with illustrated diagrams to facilitate effortless installation and configuration.
