Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an external visual confirmation system provided at a portion of a space where people live and stay, such as a house and various business establishments, and more particularly, it is provided at a front door of a house and has a crime prevention function. For effective systems.

[0002]

2. Description of the Related Art House entrance doors are often provided with door scopes for confirming visitors. However, for children, elderly people with bent waists, etc., the door scopes are located too high, or their backs are tall. On the contrary, there is a problem that a person with a high level cannot look through unless the posture is lowered considerably. Even a person who does not have such a problem may find it troublesome to check the outside with the door scope, and often unlock the door without making this check. As a matter of course, unlocking without checking the outside is not preferable for crime prevention.

In view of the above-mentioned problems relating to the door scope, there are some kinds of apparatuses for attaching an image pickup means such as CCD using the installation portion of the doorscope and confirming an image picked up by the image pickup means on an indoor monitor. Proposed. By using such an external imaging device, the outside can be visually recognized on the monitor, so that it is possible to visually recognize the outside more easily regardless of age or sex, as compared with the case where the door scope is used.

[0004]

The external visual recognition device using the image pickup means has the above-mentioned advantages, but has a problem left unsolved in the future. First of all, the conventional external visual recognition device is to check the outside from the purpose, but its function is insufficient in dealing with the absence of a family member, especially considering crime prevention. There are still a lot of points to remember.

That is, a recording device can be usually connected to the conventional external visual recognition device, and therefore a family member who has returned from the house can know the visitor by checking the recorded image. . However, since the visitor side does not know that such a recording is being done, many will return as it is, except for a few cases where memos are left, so for visitors who are absent from home, The above external viewing device is practically useless.

More serious than the above points is a security problem. For example, recently, the lock of the entrance door is unlocked with a special tool, and damage by a so-called picking criminal who steals has been occurring successively, but when a crime by such a picking criminal is performed, in the conventional external visual recognition device, The outside of the door is almost the same as the conventional door scope, or is completely the same by using the conventional door scope. For this reason, when the picking offender confirms that the housekeeper is absent by checking the chime or from outside the house, the picking offender commits the offense without noticing the existence of the external visual recognition device.

A criminal who unlocks and enters the house becomes aware of the presence of the external visual recognition device only when he looks at the inside of the door. A criminal who perceives that his criminal activity was recorded may destroy or take away the external imaging device or the recording device connected thereto. In other words, the conventional external visual confirmation device suffers from the fact that the structure of the door exterior is not different from that of the conventional door scoves, and thus it is not possible to stop the execution of a crime.

Recently, a dummy camera that does not function is sometimes installed at a visible position in order to prevent the execution of a crime. However, depending on the presence or absence of wiring of the camera, the connection state of the wiring, etc. Seeing through as a dummy,
It is said that criminals are often executed, and the installation of such a dummy camera is not always effective in deterring crime.

[0009]

SUMMARY OF THE INVENTION The present invention is constructed in view of the above problems, and greatly enhances the crime prevention effect of an external visual recognition device, and also has a multi-functionality such as reception of a message from a visitor when a home is absent. It is a visitor confirmation and crime prevention system using an external visual recognition device configured to have. That is, the external visual recognition device, which is the main configuration of the present system, is composed of an internal unit installed in the door and an external unit provided on the outer surface of the door. The external unit is a sensor for detecting the presence of a person, such as an infrared sensor. The internal unit has a display means for displaying predetermined information to a person in front of the door by voice or an image, and a microphone for receiving voice information such as a message of the person if necessary, and the internal unit has image information of the captured image. Is a visitor confirmation and crime prevention system using an external visual recognition device, characterized by having an image display means for displaying and a recording means for recording image information and audio information from an external unit.

[0010]

DETAILED DESCRIPTION OF THE INVENTION When a person approaches a door provided with an external unit of the external visual recognition apparatus, an image pickup means is activated by a human detection sensor such as an infrared sensor to display an image on a monitor of an internal unit. When the family member is absent, the device set in the absent mode starts recording together with image capturing. Immediately before the start of this recording or at the same time as the start of recording,
Characters are displayed on the image display means of the external unit, or a voice is displayed by a speaker, to indicate that the imaging and recording are being performed and that the requirements stated orally are also recorded.

In the event that the person detected by the sensor is the picking offender, the display of this display makes the offender feel dangerous that he or she is picked up and recorded, and immediately without committing a crime. The escape and crime will end in an attempt.

On the other hand, when the person detected by the sensor is a visitor, a post office worker, an employee of a courier company, etc., if the next visit time, purpose of the visit, etc. are verbally stated, the family member who returns home is recorded. By confirming the information provided, it is possible to confirm the visitor and the purpose of each visitor, and to take appropriate measures such as contacting the other party.

[0013]

Embodiments of the present invention will be specifically described below with reference to the drawings. 1 and 2 show a configuration example of an external visual recognition device that constitutes the present system. The external visual recognition device is composed of an internal unit installed on the indoor side and an external unit provided on the outer surface of the entrance door or a wall surface adjacent to the entrance door.

Reference numeral 7a denotes a lens portion of a plate image pickup means 7 (described later) using a CCD or the like, which directly uses a conventional door scope or uses a dedicated lens instead of this door scope. In any case, a wide-angle lens capable of capturing a wide field of view is used as the lens unit 7a.
Reference numeral 8 denotes a person detecting means, which is configured as a sensor for detecting a person in front of the door D. For example, an infrared sensor or the like that detects the body temperature of a person can be used as the person detecting means 8.

Reference numeral 9 denotes a speaker, which is used in place of or in addition to the character information by the image display means 6 to output predetermined voice information set in advance. Reference numeral 10 denotes a microphone, which is used by a visitor to input predetermined voice information such as a message verbally transmitted by the visitor in response to the guidance by the character information or voice information. Note that the speaker 9 also functions as an alarm means for issuing an alarm sound in an emergency described later. Reference numeral 11 is a door hinge, and 12 is a door knob. Further, FIG. 2 shows a state of the configuration shown in FIG.
Is a visitor.

It should be noted that FIGS. 1 and 2 show only an example of the structure of the external visual recognition device, and the present invention is not limited to the illustrated structure. For example, the internal unit is not attached to the inner surface Da of the door and is arranged at the entrance or the living room, or the external unit 5 is not attached to the door surface Db but is attached to the wall surface near the door, or the speaker and the microphone are installed. It is possible to adopt various configurations such as another external unit.

FIG. 3 is a block diagram showing the internal structure of the external visual recognition device. The configuration of each part shown in the above blocks will be described with reference to the flowchart of FIG. 4 showing the operating state of the system. The flow shown in FIG. 4 shows the operating state of the system in a state where the system is set to the "absence mode" when the family member is absent.

First, the "absence mode" is set by using the switching means 3 of the internal unit 1. In the "absence mode", the sensor which is the person detecting means 8 is ON (SA
1) For example, the presence or absence of a person who has entered within a certain distance from the sensor 8 is detected by detecting infrared rays of a certain level or higher (SA2). Upon receiving the person detection signal from the person detection means 8, the central processing unit 13 (see FIG. 4) turns on the image pickup means 7 to start image pickup (SA3), and at the same time as the image pickup, the image pickup means 5 records. Record with (SA4).

Further, the fact that the image is being picked up and the image is recorded is voiced by the character information displayed on the image display means 6 of the external unit 5, or by the speaker 9 instead of or in addition to the character information. It is output as information (SA5). Further, on the image display means 6, in addition to or instead of the character information, an image actually taken may be displayed. If the image actually captured is displayed, it will be a great restraint against the execution of a crime against a person who intends to engage in illegal activities such as intruding a house.

The above steps SA3, SA4 and A5
Each step may be processed as one step as a whole, that is, each step SA3, SA4 and A5 may be executed simultaneously, or step 5 may be executed first. Especially when step SA5 is first executed among the above three steps, when the visitor is a person who is going to commit a crime such as a picking offense, there is a high possibility that he / she will be at risk of attempting to escape due to the danger of the fact of recording. I think it will be.

If the person who is about to commit the above crime,
There is a possibility that the image pickup is blocked by blocking the lens 7a of the external unit 5 with a hand, covering with a chewing gum, or covering with an adhesive tape for fear of recording. In such a case, if the image information from the image pickup means 7 becomes zero (SA6), the central processing unit 13 causes the speaker 9 to operate.
An alarm sound is emitted via (SA7). This makes the crime more difficult to carry out. However, in this case, it cannot be said that the captured image becomes zero due to the failure of the image capturing means 7 itself, so that the image capturing apparatus may be automatically tested for a certain time when the absence mode is set.

On the other hand, when the image output from the image pickup device is continued, the central processing unit 13 uses the image display means 6 of the external unit 5 for the character information and voice information stored in advance in the display data storage means 14. Or a visitor M through the speaker 9
Communicate to. For example, "I'm out of office now. Please record the requirements as it will be recorded.", Etc. We request visitors, post office workers, and visitors such as courier to verbally message (SA8).

In the above series of steps, the person detecting means 8 continuously detects the presence or absence of a visitor, and when the detected infrared level becomes less than a set value, the central processing unit 13 indicates that the visitor is When it is judged that the player has left, the image pickup means 7 and the recording means 4 are turned off (SA9). In addition,
In the above configuration, both the image information and the audio information are recorded in the recording means 4, and the recorded information is superposed with the time information output from the timer of the own unit or the timer 15 of the internal unit 1. There is.

Upon returning from home, the family member reproduces the image or audio information recorded in the recording device 4,
Since the identification of the visitor and the purpose of the visit are clearly known, contact the visitor who visited during these absences, etc.
Appropriate measures can be taken.

FIG. 5 shows an example of the operating state of the present system when a family member is at home. When the family is at home,
It is possible to select either an automatic mode in which the system is automatically operated using the mode switching means 3 or a manual mode in which the home person directly confirms the visitor to unlock the system.

When the automatic mode is set, the person detecting means 8 which has stopped its operation is turned on and becomes capable of detecting the presence or absence of a visitor (SB1, SB2, SB3, SB).
4). When the person detecting means 8 detects a visitor in this automatic mode, the central processing unit 13 outputs the information output from the display data storing means 14, for example, "I am at home. Please wait." 6 or the speaker 9 to output as character information or voice information (SB
5) and the image pickup means 7 starts image pickup (SB6),
This image is displayed on the image display means 2 of the internal unit 1.

On the other hand, when the manual mode is set, the family member confirms the visitor's chime (SB7) and turns on the image pickup switch of the internal unit 1 (SB8) to take an image with the image pickup means 7 (SB6). The displayed image is displayed on the image display means 2, the visitor is confirmed by the displayed image (SB9), and unlocked (SB10). Even when the automatic mode is set, it is possible to unlock by checking the chime in the same procedure as in the manual mode. In this case, since the image pickup in step SB6 is automatically started, the ON operation of the image pickup switch (SB8) is unnecessary.

In the automatic mode, there are the following steps in addition to the above steps. In particular, this step can be performed immediately even if the family member is at home, while the family member is taking a bath or doing some extra work, even if the visitor is confirmed by the chime, or if the family member hangs clothes on the balcony. This is effective when it is not possible to confirm itself.

The central processing unit 13 shown in FIG.
When the detection of the person continues even after a predetermined time (for example, 1 minute) has elapsed (SB4), the image display means 6 or the speaker 9 displays, for example, "currently". I can't go out to the front door. Please ring the chime again after a while. "And so on, and ask you to wait for a while (SB12).

In this state, if the person detecting means 8 continues to detect the presence of the visitor for a predetermined time (for example, 30 seconds) (SB13), it is determined that the door D has not been unlocked, that is, the housekeeper. The central processing unit 13 automatically switches the automatic mode to the absence mode assuming that the door D has been unlocked and the visitor has not been invited (SB14). As a result, the system shifts to step SA4 shown in FIG. 4 (SB1
5) After that, the message request message is displayed in the absence mode, and the message of the visitor is recorded. In addition, when switching to the absence mode, in connection with step SA8 of the absence mode, "I'm sorry.
I am not aware of your visit. It is more kind if you display such as ".

It should be noted that it is necessary not only for convenience but also for crime prevention to set the automatic mode as much as possible when the family is at home. In other words, in the manual mode, if a picker tries to enter the house, if the housekeeper is not present at the entrance due to the above reasons, the criminal misunderstands that the housekeeper is absent and enters the room. there is a possibility. There are quite a few cases in which the housekeeper was harmed by having the criminal and the houseman engage in such a situation. From this point of view, it is desirable to set the automatic mode for crime prevention even when the family member is at home.

[0034]

As described above, the present invention has been described with reference to each embodiment. According to the present invention, the visitor is actively displayed to show that the visitor is actually capturing or recording the image. If anyone is trying to break into the house,
There is a high possibility of stopping the execution of a crime, and a high crime prevention effect can be expected.

When the visitor is a visitor, a post office worker, a courier delivery person, etc., the homemaker who returned home can record the image information and voice information by giving a message verbally when the homemaker is absent. Since it is possible to accurately identify the visitor, the purpose of the visit, the visit time, etc., it is possible to respond appropriately to each visitor.
