Carlo Gavazzi Motion and Presence Detector, GUARDIAN1

Carlo Gavazzi Inc. Proximity Capacitive Sensor, Thermoplastic Polyester Housing, M18, 2 Wire 20 to 250 VAC, 12 mm, Non-Flush, Plug, SCR Break Switching

The GUARDIAN 1 is an overhead sensor for pedestrian sliding doors. The sensor has combined motion and presence (safe) detection zones. The sensor is based on CMOS camera technology and detection on image processing. The motion zone reacts only on movement whereas the presence zone reacts on both movement and presence. The motion zone can be blanked in 3 directions (front, left and right) in order to avoid detection of unwanted objects. The presence zone is taught into the sensor by recognition of some standard test targets in the setup phase. The presence zone also adapts to the surroundings to work in different weather conditions. The sensor has separate outputs for the motion and presence zones as well as a test input to test the sensor function for each door cycle.
