From Detection Systems, an ISC SIA New Product Showcase entry, the OD850 is a 50 by 50 ft., PIR/Microwave intrusion detector intended for use outdoors and in other harsh environments. The OD850 can measure the linear travel distance (LTD) of a target to provide excellent catch performance of people while ignoring stationary objects with slight movement such as tree limbs and hanging signs. The combination of advanced processing techniques and mechanical design combine to provide a detector that offers superior performance in a wide range of weather conditions.
