The device is ideal for protecting gates, fences, as well as entrances to buildings and valuable objects in open spaces. A solid housing with an IP65 protection rating guarantees reliable operation in difficult weather conditions, such as heavy rain, snow, or dense fog. Thanks to the Automatic Gain Control (AGC) system, the barrier can maintain operational stability even with a 99.5% loss of signal energy caused by extreme weather. Mounting on a wall or pole is intuitive due to the wide range of optics adjustment (±90° horizontally and ±10° vertically). It is a professional solution for museums, industrial facilities, and private properties, providing discreet and effective property protection. The main advantages include the triple beam, an impressive range of up to 250 meters outdoors, and a wide supply voltage range from 12V to 24V DC. During a continuous beam interruption, the barrier does not return to its initial state, which is crucial for controlling barriers or entrance gates.

The professional AN900-B250 infrared barrier is an advanced component of perimeter protection systems, designed for early detection of intrusion attempts into a secured area. Unlike standard PIR detectors that react to movement inside a room, active barriers allow for the creation of an invisible line of protection outside the facility. The system based on infrared barriers is intended to trigger an alarm when an intruder is still outside the building, before they manage to break in. This model utilizes three synchronized infrared light beams, which significantly reduces the risk of false alarms triggered by small animals, leaves, or environmental factors.

Software and algorithms
Built-in firmware performs advanced real-time digital signal processing. The Automatic Gain Control (AGC) system intelligently adapts the device sensitivity to difficult environmental conditions. The software allows for precise differentiation between human-sized objects and smaller disturbances thanks to configurable time delay (50-700ms). Control algorithms ensure operational stability even at 99.5% IR beam energy loss, preventing false alarms during dense fog or snowfall. The system continuously monitors the TMP contact to detect mechanical tamper attempts.
