The Xovis 3D Stereo Vision Person Tracking Sensor Series comprises two sensor types: the People Counting Sensor 2 (PC2) and the People Counting Sensor 3 (PC3). For every sensor, the mounting height lies between 2.2 m up to 20 m. To optimize the area coverage the sensors are availabe with various different lens options; the PC 2 Series comes with three options while the PC 3 Series are featured with even five lens choices. Starting at an installation height around 6.5 m, a constant coverage of 100 square meters is granted.The Xovis PC 3D stereo vision sensor integrates a powerful and specialized processing engine, implemented in FPGA technology, that makes it possible to perform all video analytics (full-image individual passenger tracking) on the sensor itself. Since the whole processing is performed on the sensor, no video streaming is necessary, and data privacy is guaranteed. Compared to normal video technologies, the 3D technology is much more robust.
