The aim was to find a new dimension: the ideal detector with high-frequency technology for outdoor use. The iHF 3D uses the newly developed intelligent high-frequency technology from STEINEL PROFESSIONAL for perfect and precise detection outdoors. The active sensor detects human walking movements in a radius of 8 metres with equal precision from any direction. The iHF 3D sensor has a coverage angle of 160 degrees. Its innovative 3D aerial technology allows the detection zone to be precisely set on three axes to cover the full area. Each axis has a reach of between 0.5 and 8 metres.
Signal analysis allows the iHF 3D sensor to distinguish between moving persons and moving objects, such as bushes or animals. This precludes the risk of switching errors and ensures that only people are detected. Special filters prevent registration of rain, wind, snow and leaves, as well as other interfering factors, such as insects. Since detection is unrelated to temperature, there is no risk of switching errors due to extraneous heat sources or extreme temperatures. A KNX version of the iHF 3D sensor is also available for incorporation into the building services automation.
