Abstract

An adaptive elevator security system has a security module (52) which uses data stored in a configuration data element (64) to update a security state data element (62). The security module (52) provides data from a raw car/hall call data element (56) to a filtered car/hall call data element (58) according to data stored in the security state data element (62).
