Abstract (en)
[origin: EP0322204A2] A detector unit, especially for a "child minding" system in hotels, leisure complexes, etc., is a portable unit (12,14) comprising means to sense movement (24a,24b) and noise (22) within a zone being monitored. An alarm signal can also be generated manually from the unit by push-button means (26). The unit will only trigger a positive alert signal if detected movement and/or noise does not conform to preset tolerances or patterns. A plurality of units are linked to a central control which is itself connected to a plurality of remote display units on each of which a characteristic alert signal is displayed.
