DE19627996A1 - Acoustic room monitoring arrangement e.g. for babies - Google Patents

Abstract

The monitoring arrangement includes a microphone which is coupled to a programmable telephone switch gear via an interface unit with a Schmitt trigger. The interface unit initiates a connection to the switch gear when a noise exceeds an adjustable threshold. A connection to a predetermined subscriber is set-up and disconnected after a first predetermined time independent of the noise volume. The set-up of a new connection is to the telephone switch gear is enabled after a second predetermined time.

Description

The device for acoustic room surveillance in children's rooms in mother-child homes or clinics or hotel rooms is used to monitor infants and young children and / or children with the purpose of freeing themselves mother or parents in the building, Can move terrain or the place and at the same time it is guaranteed that the Children are heard when needed.
