The invention relates to a data collection and monitoring system for at least one defined space (1) within a public or commercial facility, comprising: a plurality of sensors (5a, 7a, 9a, 10a, 11) each monitoring a predetermined parameter; and a data collecting unit (12) arranged for communicating with said sensors (5a, 7a, 9a, a, 11) within a range (r) of communication which corresponds to the extent of said defined space (1), with at least one mobile device (17) for a user (16) and with a central server (14) which is associated with a storage medium (15). The storage medium (15) is adapted for storing and monitoring data related to said sensors (5a, 10 7a, 9a, 10a, 11). According to the invention, said data collecting unit (12) is arranged for forwarding data relating to the sensors (5a, 7a, 9a, 10a, 11) to the mobile device (4) when the mobile device (17) enters said space (1).
