From GE Security, the RCR-90 motion sensor is part of the dual-technology PrecisionLine series, which also includes the RCR-50, RCR-PET, RCR-A, and RCR-C. PrecisionLine dual technology motion sensors from GE Security offer new, easy solutions for the most challenging residential or commercial applications. Using a sophisticated combination of precision-controlled radar and passive infrared (PIR) technologies, these sensors provide total “coverage-on-demand.” The RCR-90 sensor reduces installation and training time because the installer is not required to make any complicated adjustments to the sensor. Coverage-on-demand ensures that the sensor detects only objects within a precise area, and not in adjacent rooms or outside – a common problem for less sophisticated microwave dual-technology sensors.
