Technical Examples
  1. An apparatus and technique for providing a monitoring alarm telephone which not only automatically dials a predetermined alarm notification telephone number upon activation of a suitable alarm device (e.g., tripping of a motion detector), but which also provides audible monitoring of the secured premises using the automatically dialed telephone call. In one embodiment, an open channel is established between the monitoring alarm telephone and a called telephone allowing sounds from the secured premises to be passed on to the called party. A silent monitoring alarm is provided by muting the speaker of the monitoring alarm telephone upon activation of the alarm device. In another embodiment, a cordless telephone includes a motion detector and forms a monitoring alarm telephone. The microphone of either the remote handset or the base unit may be used to provide the monitored sounds to the automatically called party. Alternatively, sounds picked up by both the microphone in the remote handset and the microphone in the base unit may be combined (e.g., conferenced) and provided over the automatically established telephone call to provide flexible and thorough audible monitoring of the secured premises.
