The new 3D Image Sensor from Panasonic System Solutions Company of Secaucus, New Jersey, works in full ambient light for access-control applications. For anti-tailgating and high-sensitivity automatic door applications, it works with the BM-ET200 Iris Recognition Camera System to heighten security. Placed in the ceiling above a door, the sensor determines whether one or mul­ti­ple individuals are trying to access the door where an iris reader is installed, and it triggers an alarm if it detects a second individual tailgating the first person. The sensor can also count people, detect the presence of a body, and act as an elevator sensor. It has a 50- x 36-degree field-of-view, operates at 12 frames-per-second, and offers a detection range from 4 to 30 feet.
