These sensors with Time of Flight (ToF) technology through the emission of a series of laser beams, allow the creation of very large monitoring surfaces (up to 200 meters) where to detect the presence of static or moving objects, with precision of a cm.
Applications can be different, for instance:
Detection of access attempts in the perimeters
Through the creation of a “carpet” of planar rays on a walkable area, it is possible to monitor in real time people, things, means. For example, this mode is used in airports to detect “unattended object”
Through the creation of a “tent” of rays in a passage, it is possible to monitor in real time the transit of people or vehicles.
