Motion Sensor


The bi-directional IR-9ZBS passive infrared motion sensor provides quality detection and employs Adaptive Digital Signal Processing (ADSP) algorithms to effectively reduce false alarms. With its advanced authenticated two-way encrypted wireless link (2.4GHz DSSS), the IR-9ZBS guarantees excellent communications range and successful signal transmission. This easy-to-install sensor is powered by a lithium battery with battery life lasting more than 4.5 years.
