The 180 m far adequate passive IR motion detector SPI 108 is developed in cooperation with ASAS systems engineering for outdoor use. You have a robust IP 66 – aluminum enclosure. The high-quality germanium optics with extremely resistant DLC layer guarantees gapless monitoring of Detection range with a vertical opening angle of 90°.
Thus the point of installation is secured and monitoring gaps be excluded on flexing points or corners. The horizontal angle of the monitor curtain is only 1.0° small and geometrically exactly defined, to avoid unwanted alarms from the environment. The detector is in its operating position > 30 ° inclined, so there are no indicatives of the real detection range.
