Abstract

A monitoring system for entry to a restricted space has a playback and recording device (1) connected in circuit with a switch (5) for detecting the presence of a caller and a microphone/loudspeaker (3) connected in parallel with the playback and recording device. The microphone/loudspeaker (3) is preferably located externally of the restrictive space and a further microphone/loudspeaker (7) is connected internally of the restrictive space. When a caller operates the switch (5) the microphone/loudspeaker (3) is connected to the playback and recording device (1) and to the further microphone/loudspeaker (7). A pro-recorded message on an outgoing message tape is then heard by the caller via the microphone/loudspeaker (3). At the end of the message, the caller may leave a message which is recorded on a memory device of the playback and recording device (1). By opening a switch (9), an occupant of the space can communicate with the caller via microphone/loudspeaker (7). <IMAGE>

Description

ENTRY MONITORING APPARATUS This invention relates to entry monitoring apparatus. The use of linked external and internal telephones for entry monitoring systems is unsuitable in domestic situations in which the occupant of the premises wishes to have both a choice as to whether or not the user of the external telephone is made aware of the presence of the occupant and a means of identifying the said user. Although such function can be achieved by television entry systems, these constitute an expensive solution to this problem and one therefore which is available to a very limited number of users. The present invention has for its object to provide an inexpensive alternative entry monitoring apparatus which enables the occupant of the premises to have the choice referred to.
The present invention consists in entry monitoring apparatus comprising message playback and recording means, first microphone/loudspeaker means adapted for electrical connection with said playback and recording means and for mounting at an external point of use, first switch means for actuating said first microphone/loudspeaker means, second microphone/loudspeaker means adapted for electrical connection with said playback and recording means and for mounting at an internal point of use and second switch means for disconnecting said second microphone/loudspeaker means from said playback and recording means whilst leaving said second microphone/loudspeaker means connected to said first microphone/loudspeaker means, whereby upon actuation of said first switch means, activation is caused of said first microphone/loudspeaker means and said playback and recording means to cause a recorded message to be audible at said first microphone/loudspeaker means and to enable a message to be recorded by way of said first microphone/loudspeaker means at said playback and recording ,means and, upon actuation of said second switch means, said second microphone/loudspeaker means is enabled to allow messages to be sent between said second to said first microphone/loudspeaker means.
The invention will now be described, by way of example, with reference to the accompanying circuit diagram illustrating entry monitoring apparatus according to this invention.
Referring to the drawing, playback and recording means (1) are connected in parallel with a branch comprising first microphone/loudspeaker means (3) in series with first switch means (5). Second microphone/loudspeaker means (7) are connected in parallel with said playback and recording means which has in series therewith a second switch means (9). The switch means (5) is prior to use of the apparatus in an open state and the switch means (9) in a closed state.
The first microphone/loudspeaker means (3) and first switch means (5) are mounted externally of the premises at which the apparatus is used whilst the recording and playback means, the second microphone/loudspeaker means and the second switch means are mounted within the premises.
When a caller operates the first switch means by closure thereof, the first microphone/loudspeaker means is connected to the playback and recording means and to the second microphone/loudspeaker means. A prerecorded message on an outgoing message tape cassette of the recording and playback means is then heard by the caller in the first microphone/loudspeaker means. At the end of the message, the caller can leave a message which is recorded on a second message receiving cassette ,tape of the playback and recording means (1). Whilst that message is being received, an occupant of the premises can hear the message in the second microphone/loudspeaker means. The occupant of the premises then has the choice of allowing the message to be recorded or to effect opening of the second switch means (9) and then speaking directly to the caller. The opening of the switch (9) disables the playback and recording means.
As the second switch means (9) is normally closed, the occupant of the premises can actuate the playback and recording means to listen to messages recorded thereon.
Those skilled in the art will appreciate that the apparatus described may incorporate means of known form enabling the occupant of the premises remotely to actuate the door lock so that access to the premises is afforded the caller.

Claims (8)

CLAIMS:
1. An intercom for a door or the like, having means for recording and playback of messages.
2. A monitoring system for entry to a restricted space having: - storage means for storing a message; detector means for detecting the presence of a caller at the entry; message means responsive to the detector means for communicating the message to the caller; transducer means for receiving spoken utterances of the caller; recording means for recording said spoken utterances; and monitor means for reproducing said utterances.
3. A monitoring system according to claim 2 wherein the monitor means comprises loudspeaker means selectively operable to reproduce said spoken utterances from said transducer means while said utterances are being spoken, or recorded utterances from said recording means.
4. A monitoring system according to claim 2 or claim 3 having means for connection to a telephone system whereby recorded utterances may be remotely reproduced.
5. A monitoring system according to any one of claims 24 having lock release means operable by an occupant of the space for enabling access to the space by the caller.
6. A monitoring system according to any one of claims 25 having annunciator means for alerting an occupant to the presence of a caller.
7. A monitoring system according to any one of claims 26 wherein the detector means includes a push button for operation by the caller.
8. A monitoring system constructed and arranged substantially as herein described with reference to and as illustrated in the accompanying drawings.
