Groundbreaking sensor technology. Targeted detection. Hallways and long corridors have specific requirements for sensor performance. The detection field of the sensor needs to be narrow yet 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 environments. It features a special corridor detection and a 45° opening angle, allowing it to monitor areas up to 20 x 4 meters tangentially.
