Infrared Fence Alarm System, Smart Variable Frequency Human Body Sensing Light Grating Curtain Detector with Digital Frequency Modulation

Infrared Fence Alarm System, Smart Variable Frequency Human Body Sensing Light Grating Curtain Detector with Digital Frequency Modulation Description

Designed for high-reliability perimeter security, this infrared fence alarm integrates smart variable frequency technology with advanced human body sensing. The light grating curtain forms an invisible barrier that triggers an alert when two or more beams are interrupted. Built-in digital frequency modulation demodulation ensures stable operation in electrically noisy environments. With automatic focusing and acousto-optic calibration, installation is streamlined and accurate. Ideal for both residential and commercial applications, it delivers tamper-proof, animal-immune protection that adapts to changing conditions, keeping your space secure around the clock. Advanced Detection Technology : Utilizes Smart Variable Frequency and Human Body Sensing to accurately detect intrusions while distinguishing between humans and animals, reducing false alarms in residential and commercial environments. Universal Digital Frequency Compatibility : Engineered with wide voltage support 8-33VDC, ensuring Stable performance across diverse power systems and climates for uninterrupted surveillance. Intrusion Alarm Protection : Features comprehensive security mechanisms including tamper resistance, wire-cutting resistance, and infrared interference prevention to maintain system integrity under attack attempts. Automatic Focusing Circuit : Enhances beam alignment precision for consistent signal transmission over long distances up to 60 meters, minimizing manual calibration needs. Versatile Installation Scenarios : Suitable for use around windows, balconies, garages, villas, schools, and office buildings, providing flexible perimeter protection for both indoor and outdoor spaces.
