Description

This reference design highlights the IWRL6432AOP's ability to detect motion and presence for outdoor surveillance systems, such as home cameras, video doorbells and automatic controls. IWRL6432AOP detects people and objects at long ranges and high angles through efficient antenna design, consumes very little power by cycling into deep sleep modes, and filters out nearly all false alarms through advanced algorithms. A multi-stage architecture allows the radar to achieve all three attributes (long detection range, low power consumption, low false alarm rate) at the same time. Devices with the IWRL6432AOP can benefit from faraway detections, long battery life, and fewer false alarms.
