Abstract

PURPOSE:To telerecord a visitor to an absent house through inexpensive constitution by telerecording a video from a television camera as a still picture when there is a call, and telerecording the telerecording picture on another tape only when there is no answer to the call. CONSTITUTION:When the visitor presses a call button 4a, the buzzer of a house device 6A sounds; and the output 18a of an OR gate 18 goes up to H and outputs 23a and 24a of timers 23 and 24 also go up to H. The 1st telerecording device 20 telerecordes a still picture of the visitor through the television camera 2. If there is no answer to the call at the device 6A, the contact 15aA of a relay is left released. Therefore, the output of an OR gate 27 is at L and the timer 24 is not reset, so its output 24a is still at H. When the outut 23a goes up to H a specific time after the output 18a goes up to H, and the output 26a of an AND gate 26 goes up to H and is inputted to the 2nd telerecording device 21. The contents of the device 20 are transferred to the device 21 and the still picture of the visitor is telerecorded by the device 21.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for monitoring visitors to an apartment complex.

There are common entrances to KH apartment complexes such as Manojon, where visitors can press a button to call up the place they are visiting. At this time, visitors are checked using a monitoring television receiver (12 is referred to as a lower monitor television) in the dwelling unit, as shown in Utility Model Application Publication No. 56-61'78. Examples thereof are shown in FIGS. 1 and 2.

In the figure, (1) is an entrance device installed at the common entrance, which includes a television camera (hereinafter referred to as television camera) (2), a telephone such as an intercom (3), and call buttons (4a) to
(4n) consisting of dwelling unit selection buttons (4). (5) is the actual entrance that automatically locks or unlocks the common entrance, (6A) to (6N) are the residential units installed in the 1st to Nth units (F-), and the contacts (15a )
A monitor TV (7) is connected to a TV camera (2) via a contact point (15b). 8) When picked up, the contact (8a) closes) and an unlock button (9) are arranged. Furthermore, dwelling unit equipment (sA) ~ (6N) K n, call button (4a)
- (4n), and when the input becomes rnJvc, the output becomes rHJ for a predetermined period of time (for example, 30 seconds).A timer (101, buzzer II) is connected to each of the timer (10) and the contact (8a), and fcAND gate i12+, N
OT gate t-131, i-s free lag flop (hereinafter referred to as memory) H and normally open contact D5a) + 05b) k
A connecting relay (16) is provided.

A visitor who has just arrived at the common entrance presses the call button (4a).
) When k is pressed, the buzzer (11) of the first dwelling unit sounds and the output of the timer (10) becomes rHJ for 30 seconds. During this time, pick up the handset (8) of the telephone in the first dwelling unit, and
8a) is closed, and the output of AND gate (12) is "H"
, memo January 14) is set, and its output is “H
”, the connection relay (15) is energized, and the contact (15
a), (15b) are closed. Now, the image of the television camera (2) is received by the monitor television (7), and the telephone set (3) and handset (8) can communicate. After checking for visitors at the front door, press the unlock button (9) and the front door lock (5) will be unlocked.
+ is unlocked and visitors can enter the residence.

When the transmitter/receiver (8) is returned to its original position, the contact (8a) opens and the output of NOT game H131 becomes ``RH'', and Memo 1
The connection relay (15) is deenergized and the contacts (15a) and (15b) are opened.

This disconnects the entrance device +11 and the dwelling unit device (6A).

Although the above-mentioned system is extremely useful for crime prevention in apartments, etc., there is a risk that it can be easily exploited to search for homes where people are not home. In other words, if the house is not found,
By some means (for example, when children etc. come and go,
As long as the person does not enter the apartment using the ``4'' and ``telephone'' etc., the house is left untouched by the intruder. Therefore, recording the images from the television camera (2) on a video tape recorder can be useful as evidence at a later date, but since it is necessary to record all visitors, a video tape recorder has a large recording storage capacity. If you don't use something, you'll have to use something to create a song.

This invention improves the above-mentioned problem by recording the image of the TV camera as a still image when there is a call, and recording the above recording separately only when the call is not answered. So that you can record with an inexpensive configuration (
The purpose was to provide residential visitor monitoring equipment.

An embodiment of the present invention will be described below with reference to FIGS. 3 to 6.

In the figure, 071 is installed in the entrance device (1), and for example, a notification device that announces or broadcasts, ``Please excuse me, but I have recorded the call while you are away,'' and (18) is the entrance device fl) K is an OR gate that takes the outputs of call buttons (4a) to (4n) as input, (18a,) f4 its output, fJ9) is the management device installed in the manager's room, and the details are shown in Figure 4. , the first recording device (D) temporarily records the image of the television camera (2) as a still image, and the second recording device (D) also records the image of the first recording device (2) for a long period of time.

In addition, except for the above, the first
It is similar to FIG.

Next, the operation of this embodiment will be explained.

Now, when the call button (4a) is pressed, the buzzer (11) of the first dwelling unit sounds, the output (1sa) of the OR gate (18) becomes "H", and the output of the timer (c), (c). (23a) and (24a) become "HJ.Meanwhile, memory Cl8il"j is set, and its output Q1-1
r) (J. When the synchronization separation 1 Moeji 61) emits a synchronization signal from the signal of the TV camera (2), the output of the AND gate becomes rHJ, and the monostable element LA only takes the time required to write one screen. Send the signal to the storage device (b).

The example storage device then writes the output of the A/D converter (to) to the address specified by the address calculation circuit (to).

Now, the storage device (A) is a still image of the visitor taken through the television camera (2).

On the other hand, when the first dwelling unit picks up the handset (8) in response to the call, the connection relay (15) is energized as described above.
An image is received on the monitor television (7), and the handset (8) becomes capable of making a call. Further, since the contact (15aA) is closed, the output of the OR gate (a) becomes rHJ, the timer (to) is reset, and the output (24a) becomes "L" at time t3 in FIG. At this time, the output of timer @ (23
a) is “H”, the output of NOT gate (c) (25a
) 'd rLJ Vc note, AND gate ti output (26a) 1l-jrHJ K ij f
There is no x. Therefore, the second recording device C21) does not operate.

Next, if the first dwelling unit does not respond to the call, the connection relay (I6) is not energized and the contact (15aA) remains open. Therefore, the output of the OR gate (c) is also rJ, timer nu is not reset, and its output (24
a) remains "H". Output (1sa) is rHJK
After 30 seconds have elapsed, at time t1Vc in FIG. 6, the output (23a) of timer 4 becomes "L" and NO.
The output (25a) of the T gate (to) becomes id rH,J. Therefore, AND cable output (26a) ld
rJ, and the transfer control circuit (
input). The transfer control circuit cfj then issues a transfer signal, the contents of the storage device ■ are transferred to the storage device □□□, and the above-mentioned still image is recorded on the second recording device j#+211. In this way, the second recording device Qυ is activated only when the dwelling unit does not respond, that is, when the dwelling unit is away, so its recording storage capacity may be small. Furthermore, since recording is performed when the call button (4a)' is pressed, there is almost no possibility that the visitor will be out of the image area of the television camera (2) and recording will not be possible.

Furthermore, the AND gate output (25a) is sent to the notification device (1η) to display or broadcast that the visitor has been recorded.

Therefore, even if the visitor is looking for an absentee house, he or she will not be able to take action such as breaking into the house.

In addition, the monitor TV (7) of the dwelling units (6A) to (6N)
) may be omitted.

Further, in the embodiment, the second recording device ■υ is not activated when a call is answered, but the second recording device ■υ may be activated. That is, dwelling unit equipment (6A) to (6N)
A K switch may be provided, and when it is determined that the person making the call is a suspicious person, the switch may be operated to activate the second recording device 21) to record the entire suspicious person.

In addition, in the embodiment, the storage device (2) of the first recording device @ (4) has a storage capacity for, for example, one still image, and the storage device (to) of the second recording device (4) has a storage capacity for, for example, 10 still images. Although the recording device has a storage capacity, it is also possible to provide both functions in a single recording device. That is, for example, one recording device K has a storage capacity for 11 images, and when there is a call, it records on the first image, and when there is no response to the call, it records on the second image. The next time there is a call, the first recording is rewritten, and the next time there is no response, the third recording is made, and so on.

As explained above, in this invention, when the call button on the telephone at the common entrance is operated, the video of the TV camera is temporarily recorded as a still image, and the call is not answered even after a certain period of time has elapsed since the call was made. Since the above-mentioned recording is made to be recorded by the second recording means, the recording device only needs to have a memory capacity for temporary recording and a memory capacity for recording only visitors to the house while you are away. Monitoring can be realized with an inexpensive configuration.
