Classrooms are the ideal application for the WV-PDT Dual Technology Wide View Sensor. Installed in the corner of the room along the entrance wall, this inconspicuous sensor provides line of sight PIR detection of small movements up to 40 feet away, and combines overlapping Microphonic™ detection around obstructions. The WV-PDT is also used in corridors due to its ability to view up to 70 feet for walking motions, or large open storage areas where obstructions may block the PIR’s ability to view. For large lecture halls, multiple WV-PDTs may be wired together, or along with any other low voltage sensors.
