The IRC3000 and IRC3010 are People Counting Devices with the imaging optics, sensor, signal processing and interfacing electronics all contained within a moulded plastic housing.
The unit is used in a downward looking manner, as the unit functions optically ‘seeing’ the heat emitted by people passing underneath as Infra-Red radiation, collected through a germanium lens with a 60° field of view.
The sensing area is a square on the floor whose width is approximately equal to the mounting height, for example, at 3.5m the unit ‘sees’ a 3.25 x 3.25m square on the floor. Mounting height ranges between 2.2m and 4.8m can be covered with the standard lens, whilst a 40° field of view version offers a mounting height range of 3.5 to 7.5m.
