INSTALLATION FOR DETERMINING THE NUMBER AND THE DIRECTION OF PERSONS STAYING IN A MONITORED ROOM OR PASS-THROUGH

摘要

In an installation for determining the number of persons inside a monitored room or so-called pass-through, a sensor field is generated by IR-sensors. An evaluation unit uses as discriminating criterion the detection of moving bodies and generates for an entrance control unit a signal, allowing or barring the entrance of a person.
