Pioneering sensor technology. Targeted detection. Corridors and long hallways have specific requirements for sensor performance. The detection field of the sensor needs to be narrow but long. This is the only way to effectively cover long sections with as few sensors as possible. The IS 345 is a proven specialist for such applications in indoor areas. It features a special corridor detection and a 45° opening angle, allowing it to monitor areas of up to 20 x 4 meters tangentially.
