(57) [Summary] [Purpose] When an intruder into the surveillance area is detected, the collection center automatically and quickly and accurately determines whether or not it is a true intruder. Therefore, a crime prevention monitoring system capable of making more reliable notifications to detention institutions such as police stations is provided. [Structure] On the collection center side, an image database is pre-registered for each surveillance area with image information of qualified persons admitted to those surveillance areas. If there is an intruder in the surveillance area,
While collecting the image information of the intruder through the surveillance camera, this image information is collated with the image information of the person qualified to enter the surveillance area registered in the image database, and the intruder enters the surveillance area. Assuming that the intruder is an illegal intruder, it is notified to the detaining agency on condition that it does not match any of the qualified persons.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is based on an image pickup signal picked up by a surveillance camera installed in an arbitrary area to be monitored, such as an office, a store, a school, a bank, a factory, or the like. The present invention relates to a crime prevention monitoring system for remotely monitoring the presence or absence of illegal trespassers.
2. Description of the Related Art Conventionally, as this type of crime prevention system,
A security sensor such as a heat ray sensor or an infrared sensor is arranged in advance in the monitored area, and when the security sensor detects that an intruder is present in the monitored area, a public line or a dedicated line is notified to that effect. A system is known in which a concentrator installed in a security company or the like is automatically notified via a telephone. And in such a system, a security officer rushes to the scene based on an automatic notification to the above concentrator, and if an abnormality is confirmed, a police station, a fire station, etc., on the spot,
The necessary organizations will be contacted and reported.
Generally, the security sensor and the concentrator are provided in accordance with a transmitter having an automatic call function for the public line and the private line, and a call from the transmitter through the public line and the private line. When the transmission path is set to a communicable state, and a notification signal transmitted thereafter is connected via a receiver or the like that collects the signal to the concentrator, and a security sensor detects an intruder in the monitored area. (1) The transmitter is activated based on the intruder detection signal from the security sensor.
(2) The activated transmitter automatically calls a receiver installed in a security company or the like.
(3) As a result, the transmission path between these transceivers becomes communicable.
(4) A predetermined notification signal indicating that identification information and the like regarding the monitoring area is added is transmitted from the transmitter to the receiver through the transmission path.
(5) The transmitted notification signal is demodulated in a predetermined manner through the receiver and input to the concentrator.
[0008] Automatic notification is made to the concentrator according to the above procedure.
As described above, in the conventional system, as long as the detection accuracy of the crime prevention sensor is high, it is possible to detect the presence or absence of an intruder in the monitored area to some extent. However, on the other hand, the presence or absence of such an intruder is determined only by the above-mentioned crime prevention sensor. Therefore, for example, when the intruder in the surveillance area is qualified to enter the surveillance area, a mouse or a dog. , A cat, a bird, etc. are detected as an intruder, and further, the sensor itself and the above-mentioned transceiver etc. are malfunctioning, there are many false alarms due to, etc. However, it is extremely low. Even if there is the above-mentioned notification through the so-called terminal devices such as the above-mentioned security sensors and transmitters installed in the surveillance area, it will be an accurate notification until the guard arrives at the scene and confirms the actual situation. In reality, it is not known whether it was a false alarm or a false alarm.
Further, in such a system, even if the above-mentioned notification is accurate, a time loss until the actual condition of the site is confirmed by the guard is inevitable.
In recent years, in order to improve the reliability and to deal with the situation where confirmation is urgent,
A surveillance camera such as an ITV camera is also installed in the surveillance area, and the terminal device transmits the image pickup signal from the surveillance camera together with the notification signal, so that the concentrator side appropriately transmits the picked-up image. Although there is a crime prevention monitoring system that allows you to check the actual situation of the scene on the spot in real time while monitoring through a display device, is an intruder in the surveillance area qualified to enter the surveillance area? Unless it is a person who knows all the circumstances regarding the surveillance area, it is difficult to judge whether or not even the guards are concerned, and it cannot be said that such captured images are not always effectively utilized. ..
Particularly in recent years, the number of terminals installed tends to increase more and more, and not only the accuracy of detecting illegal intruders and the notification accuracy of the crime prevention monitoring system but also the reliability thereof are serious problems.
The present invention has been made in view of the above circumstances, and when an intruder in the surveillance area is detected,
The collection center can automatically and quickly and accurately determine whether or not it is a trespasser, and can make more reliable notifications to detention agencies such as police stations. The purpose is to provide a security monitoring system.
In order to achieve such an object, according to the present invention, based on an image pickup signal picked up by a surveillance camera installed in an arbitrary surveillance area to be monitored, surveillance information about the surveillance area is provided. A terminal device that is formed and transmits this to a predetermined transmission line, and the monitoring information transmitted through this transmission line is subjected to a concentration process to collectively and remotely manage the monitoring information for one or more monitoring areas. On the premise of a crime prevention monitoring system including a concentrator, the terminal device has (a) a sensor means which is disposed in the monitoring area and detects the presence or absence of an intruder in the monitoring area.

(C) Image processing means for converting the captured imaging signal into data as image information.
(D) Identification information setting means for presetting identification information about the monitoring area.
(E) Clock means for outputting time data.
(F) In response to the detection of the presence of an intruder by the sensor means, the time data of the clock means is acquired, the concentrator is called through the transmission line, and the image information converted into data and First notification control means for constructing the monitoring information based on the identification information of the monitoring area and the acquired time data, and transmitting the constructed monitoring information to the concentrator that has called.
Each of them is provided with (g) image demodulation means for separating the image information from the transmitted monitoring information and demodulating the image information.
(H) Identification information extracting means for extracting identification information about the monitoring area from the transmitted monitoring information.
(I) An image database in which image information of persons qualified to enter the monitoring areas is registered in advance for each of the monitoring areas.
(J) The demodulated image information is all of the image information of the qualified person for admission regarding the surveillance area specified by the extracted identification information among the image information registered in this image database. An image collating unit that outputs a signal indicating a match when the demodulated image information matches any of the image information of the admission qualified person, and outputs a signal indicating a mismatch when the image information demodulated matches the image information of the person qualified to enter the building.
(K) When the image matching means outputs the signal indicating the inconsistency, the receiving device installed in advance in the restraint engine is called and the monitoring specified by the identification information extracted from the monitoring information is performed. Second alert control means for constructing emergency alert information for notifying that there is an illegal intruder in the area together with the time data, and transmitting the constructed emergency alert information to the receiving device that made the call.
Are respectively provided.
According to the terminal device including each of the means (a) to (f) described above, when there is an intruder in the monitored area, it is a qualified person who can enter the monitored area. Regardless of the presence or absence, the face, figure, behavior, etc. of the intruder are imaged, and the imaged information is passed through the first notification control means (f) to identify the surveillance area and the same. It is sent to the concentrator as monitoring information together with the intrusion time data to the monitoring area.
On the other hand, the concentrator which has received the monitoring information separates the image information, the identification information, and the time data from the received monitoring information, and in particular, separates and demodulates them through the image demodulating means (g). The image information is collated with the image information registered in advance in the image database (i) through the image collating means (j).
The image database (i) is, as described above, the image information of persons qualified to enter the monitoring area (usually a plurality of people) is registered in advance in each monitoring area, for example, as facial photograph information. In the image collating means (j), the identification information extracted through the identification information extracting means (h) is given, so that the image information registered corresponding to the monitoring area specified by the identification information All are searched from the image database (i), and the searched image information and the demodulated image information transmitted from the terminal device are sequentially collated.

(2) The face portion is further extracted from each of the extracted still images.
(3) A front face photograph model is created from the extracted images of the face portions.
(4) The respective images corresponding to the image information registered in the image database (i), that is, the searched images are superimposed on the created front face photograph model.
By performing the above-mentioned processing, it is determined based on the extraction of the contours and characteristic portions of these superposed images whether they belong to a matching person or a non-matching person. As a result, when the demodulated image information matches any of the image information of the admission qualified person, the signal indicating the above-mentioned match is output, and when it does not match any of the image information, the above-mentioned signal indicating the mismatch is output.
The second notification control means (k) outputs the signal indicating the inconsistency from the image collating means (j) based on the result of the image collating processing by the image collating means (j). Only when it is found that the intruder does not match any of the qualified persons entering the surveillance area, it is assumed that the intruder is an illegal intruder,
Since the above emergency call information is used to notify the detention agency, its reliability is naturally high.
The receiving device installed in advance in the restraint system is an image receiving device such as a facsimile, and the second notification control means (k) also uses the monitoring information as the emergency notification information to be transmitted. If the information (including, of course, character information) that is converted into a predetermined image based on the demodulated image information and the identification information extracted from the monitoring information and the time data included in the monitoring information is constructed, The information content as the emergency notification information will be further enhanced, and it will be possible to greatly contribute to, for example, restraint of illegal trespassers.

(M) Identification information processing means for retrieving corresponding relevant information from the identification information relevant information database based on the extracted identification information.
The provision of the above-mentioned emergency notification information is such that the retrieved identification information related information is also added to the emergency notification information constructed through the second notification control means (k). It is desirable to further increase the degree.
1 shows an embodiment of a crime prevention monitoring system according to the present invention.
As shown in FIG. 1, in the system of this embodiment, the terminal device 100, the concentrator 200, and the notification receiver 300, which are connected via the transmission lines PT1 and PT2, respectively, are roughly three. Composed of a seed device.
Of these, the terminal device 100 is a device installed corresponding to each monitored area of a house or building requested to be monitored, such as an office, a store, a school, a bank, or a factory. Yes, in particular, in each of these monitored areas, that is, in each of the monitored areas WZ, a security sensor 101 including a heat ray sensor or an infrared sensor that detects an intruder in the area, and the same area Camera 10 including an ITV camera for capturing an image of an intruder
2 are installed, and the detection signal from the security sensor 101 and the image pickup signal from the surveillance camera 102 are taken in by the corresponding terminal devices 100.
The concentrator 200 is a device installed in, for example, a security company or the like, and here, usually, the monitoring reported through the terminal device 100 arranged corresponding to a large number of monitoring areas. While collectively receiving information via the transmission line PT1, the presence or absence of an illegal intruder in the zone WZ to be monitored is comprehensively remotely monitored. Then, as a result of this monitoring, when an illegal intruder into the monitored area WZ is confirmed, the notification receiving device 300 to that effect is transmitted via the transmission line PT2.
The notification receiving device 300 is a device installed in a restraint organization such as a police station. Particularly, in the system of this embodiment, it is assumed that image transmission / reception by facsimile is performed between the concentrator 200 and the notification receiver 300.
From that, the notification information includes the address and telephone number of the invaded surveillance area, text information indicating the time of the invasion, the characteristics of the surveillance area, and image information equivalent to the intruder's facial photograph. , Shall be sent by facsimile to this binding agency.
The specific configurations and operations of these respective devices shown in FIG. 1 will be sequentially described in detail below.
Now, if there is an intruder in the surveillance area WZ shown in FIG. 1, regardless of whether or not the person is qualified to enter the surveillance area WZ, the fact is detected by the security sensor 101. To be done. The detection signal from the security sensor 101 is sent to the monitoring controller 10 in the terminal device 100.
Input to 3.
The supervisory control section 103 sends a warning set state / state by a signal S / R that the state is switched in response to a set / reset operation of an appropriate switch means (not shown).
The release state is switched, and if it is now in the "alert set state", that is, at night, etc.
In preparation for the monitored area WZ being in the absence state, the resident or employee or the like operates the switch means in advance by “setting”, and as a result, the monitored area WZ is remotely monitored through the concentrator 200. In the monitoring control unit 103, in response to the detection signal being input from the security sensor 101, the monitoring control unit 103 issues an activation signal E to the monitoring camera 102 and the first notification control unit 104. The monitoring camera 102 and the first notification control unit 10
4 is made active.
The surveillance camera 102 thus controlled in the active state starts the image pickup of the intruder who has entered the surveillance zone WZ, and sends the image pickup signal IM to the image processing section 105.
It is assumed that the surveillance camera 102 can complete the imaging of the intruder in a time of about several tens of seconds even at night.
Further, the image processing section 105 to which the image pickup signal IM is sent in this way is various equipment such as an A (analog) / D (digital) converter for converting the image pickup signal IM into predetermined image data. , A temporary storage image memory and the like, which is a well-known portion, and the image pickup signal IM of the intruder imaged by the surveillance camera 102 is image-processed by the image processing unit 105 to thereby obtain a computer. As the image data IMD that can be processed by the first report controller 1
It will be added to 04.
On the other hand, like the surveillance camera 102, the first notification control unit 104, which is controlled in the active state by the activation signal E issued from the surveillance control unit 103, makes a call to the concentrator 200 through the transmission line PT1. In the meantime, the monitoring zone ID (identification information) setter 106 detects the monitoring zone WZ.
The time data T when the ID number is acquired, and when the activation signal E is given from the clock 107, that is, when an intruder is detected by the security sensor 101.
Further, the image data IMD of the intruder image-processed through the image processing unit 105 is captured, and the monitoring information based on each of these data is constructed.
Then, when the logical connection with the concentrator 200 is secured by the above call, the constructed monitoring information is transmitted to the concentrator 200.
By the way, the monitoring area ID setting device 106 is
In terms of hardware through a DIP switch, etc., or through software through an ID number setting program,
The clock 107 is a device for setting an ID number for specifying the monitoring zone WZ, and the clock 107 is also a known device that outputs time data based on an oscillation operation by a crystal oscillator or the like. Both the monitoring area ID setting device 106 and the clock 107 may be built in the monitoring control unit 103 or the first notification control unit 104.
In addition, all of these parts constituting the terminal device 100 are always required by the backup power supply 110 so that their respective functions are maintained even if the power supply is cut off due to a power failure or the like. Power supply is backed up.
Now, in the concentrator 200 to which the monitoring information is sent from the first notification control section 104 of the terminal device 100 via the transmission line PT1, the reception control section 20 receives this monitoring information.
Receive through 1.
The reception control section 201 cooperates with the first notification control section 104 in response to a call from the first notification control section 104, and controls the transmission line PT1 in order to secure a logical connection with the terminal device. Then, by transmitting the monitoring information from the first notification control unit 104 of the terminal device,
This is received and demodulated, and the demodulated signal is sent to the ID extraction unit 20.
2, output to the time data extraction unit 203 and the image demodulation unit 204, respectively.
From the demodulated signal, the ID extraction unit 202
The time data extraction unit 2 is a part that extracts the ID number information ID of the monitored area WZ in which the intruder was present.
Reference numeral 03 denotes a part for extracting the intrusion time data T from the demodulated signal, and the image demodulation part 204 extracts the image information part for the intruder from the demodulated signal and is usually applied at the time of transmission. This is a part for releasing processing such as compression, and demodulating this as image data IMD that can be processed by the computer. Then, the demodulated image data IMD is sent to the display 205 to display its behavior and the like as a real-time image of the intruder, and is also sent to the image matching unit 206 to be registered in the image database 207 in advance. It is collated with the existing image data.
Here, the image database 207 is a database in which image information of persons qualified to enter the monitoring areas is registered in advance for each of the monitoring areas, and the image collating unit 206 is The demodulated image data IMD is the ID extraction unit 202 of the image data registered in the image database 207.
The image data IMD demodulated by comparing with all the image data of the admission qualified person in the surveillance area specified by the ID number information ID extracted through When they match, a signal M indicating a match is output, and when none of them match, a signal NM indicating a mismatch is output. An example of the image matching process through the image matching unit 206 and the image database 207 will be described in more detail with reference to FIG.
That is, here, it is assumed that the image data registered in the image database 207 is the image data corresponding to the face photograph of each person qualified to enter the building, and the extracted ID number information ID of these image data. The data searched by the image matching unit 206 based on the above, that is, the image data registered as the admission qualified person for the monitoring area WZ specified by the ID number information ID is shown as search data 207Z in FIG. It is assumed to be image data.
The image collating unit 206 that has retrieved the image data 207Z in this way first temporarily stores the retrieved data 207Z in an appropriate image memory (not shown), and then (1) through the still image extracting unit 2061 to A plurality of still images are extracted from the demodulated image data IMD.
(2) The face portion extracting section 2062 further extracts a face portion from each of the extracted still images.
(3) Through the front model creating unit 2063,
A front face photograph model is created from the extracted images of each face portion.
(4) Through the contour / feature extraction unit 2064,
One image data (face photograph information) of the search data 207Z is read, this is superposed on the created front face photograph model, and the contours and characteristic portions between these superimposed images are extracted.
(5) Based on these extracted contours and features, the determination unit 2065 determines whether or not they match, that is, whether or not the superimposed image data belong to the same person.
(6) The processes of (4) and (5) are repeated for all the image data of the search data 207Z.
The above processing is sequentially executed, and the determination unit 2
When it is determined that all of them do not match in the determination result of 065, that is, the demodulated image data IMD
Signal NM indicating the above disagreement when it is determined that the person in question is not a qualified person to enter the monitoring zone WZ.
Together with the front face photograph model data IMDF created by the front model creating unit 2063,
Output to 8. Further, in the determination result of the determination unit 2065, when it is determined that at least one match, the image matching unit 206 outputs the signal M indicating the match,
Similarly, together with the front face photograph model data IMDF created by the front model creating unit 2063, the reception management unit 2
It outputs to 08. Incidentally, in this example, it is assumed that the person in the image data IMD is an illegal intruder, and the image matching unit 206 outputs a signal NM indicating a mismatch. The image matching process itself is
With the introduction of a dedicated computer, it can be completed in about 60 seconds at most.
On the other hand, in the concentrator 200, in parallel with the image collating process, based on the ID number information ID extracted by the ID extracting unit 202, information related to the ID number information ID is searched for by the ID information processing unit 209 and the ID information processing unit 209. It is executed through the ID related information database 210.
That is, the ID related information database 21
0 means that for each of the above-mentioned monitoring areas, the relevant information indicating the address of the building including the monitoring areas, the location of the monitoring area in the building, the telephone number, the characteristics of the monitoring area, etc. The database is a database registered in advance in correspondence with the number information ID, and the ID information processing unit 209 is based on the extracted ID number information ID.
This is a part for searching the D related information database 210 for corresponding related information. The related information IDINF of the monitored area WZ thus searched is also output to the concentrating management unit 208 through the ID information processing unit 209 together with the ID number information ID.
In this way, the collection management unit 208 receives the signal NM indicating the above-mentioned mismatch (or the signal M indicating the match) and the front face photograph model data IM of the intruder from the image matching unit 206.
The DF is sent, and the ID is sent from the ID information processing unit 209.
The number information ID and its related information IDINF are sent, and the extracted time data T is sent from the time data extraction unit 203, so that, for example, in a mode shown in FIG. Is.
That is, in the collection management unit 208, the signal M / NM from the image matching unit 206 indicating the match / mismatch.
Is monitored (step S1 in FIG. 3), and this signal M / NM is
When the signal NM indicates a mismatch as in the example here (step S2 in FIG. 3), the second notification control unit 21 is immediately sent.
1 is started (step S3 in FIG. 3), and the sent front face photograph model data IMDF of the intruder, the ID number related information IDINF, and the time data T are sent to the activated second
Transfer to the notification control unit 211 (step S in FIG. 3).
Further, the reception management unit 208 uses the above M / N.
When M is a signal M indicating coincidence (step S in FIG. 3)
Even in 2), however, when a forced notification operation is performed through the console 212 by a security guard or the like who works at the communication center (step S5 in FIG. 3), the second notification control unit 211 is immediately activated in the same manner as above ( Step S3 in FIG. 3), the sent front face photograph model data IMDF of the intruder, the ID number related information IDINF, and the time data T are transferred to the activated second notification control unit 211 (FIG. 3). Step S4). That is, in the system of this embodiment,
Since the behavior of the intruder is monitored through the display 205, even if the image collating unit 206 outputs a signal M indicating a match, the behavior of the intruder is clearly suspicious, If it is determined by the above, such a compulsory notification operation through the console 212 can prevent the omission of monitoring to be minimized.
In other cases, that is, the image matching unit 20
6 outputs a signal M indicating a match (step S in FIG. 3).
2) and when the forced notification operation has not been performed (step S5 in FIG. 3), the same call collection management unit 208 starts the monthly report process without activating the second notification control unit 211.
Incidentally, the monthly report process is a process for reporting the monthly monitoring result to the client who requests the monitoring by the system. In this case, the reception management unit 208, for example, ID number information ID sent above
And the time data T, and if necessary, the monthly report information for recording them in each of the above-mentioned monitoring areas is created based on the front face photograph model data IMDF of the intruder (visitor) (step S6 in FIG. 3). , The created monthly report information is registered in the monthly report database 213 (step S in FIG. 3).
7). If there is an output request for the registered monthly report information through the console 212 (step S in FIG. 3).
8) Then, the monthly report information about the designated monitoring area is read from the monthly report database 213 and is output in a predetermined format through the output device 214 (printing device such as a printer in this case) (step S9 in FIG. 3).
The second notification control unit 209, when activated by the collection management unit 208, makes a call to the notification receiving device 300 installed in a restraint organization such as the police station. , The transferred front face photograph model data IMDF of the intruder, and the ID number related information I
The notification information is constructed based on the DINF and the time data T, and the constructed notification information is transferred to the secured transmission line P.
Send through T2. As described above, the transmission of the notification information from the second notification control unit 209 to the notification receiving device 300 via the transmission line PT2 is performed by the facsimile.
When the notification information is transmitted to the notification receiving apparatus 300 in this way, the notification receiving apparatus 300 receives the notification information in the reception processing section 301, immediately demodulates the content through the reception information demodulating section 302, and outputs the result. Device 3
Print out through 03. FIG. 4 shows the content of the printed notification information as a reference.
That is, as shown in FIG. 4, in the system of this embodiment, the facsimile transmission information includes (A) ID number related information intrusion in addition to the reporting date and the reporting person (security company) name. Address of the monitored area where the person was located Similarly, its office name (household name, store name, school name, bank name, company name, etc.) Phone number Characteristics of the monitored area (room location, surrounding conditions, environment, etc.) (B ) Time data Time of intrusion (C) Front face photograph model data of intruder This information is sent from the above created image data showing the front face photograph model of the intruder. Immediately after receiving the information through the device 300, a detention agency such as a police station can accurately grasp the contents and promptly deal with detention of the intruder.
In the system of this embodiment, the above I
Although the notification information including the D number related information, the time data, the front face photograph model data of the intruder, and the like is transmitted by facsimile, the transmission method and the transmission medium are arbitrary. In addition, for example, the notification receiving device 300. An appropriate display device that is computer-controlled is also installed on the side,
The notification information is transmitted by an image transmission technique other than the facsimile and displayed on this display device, or, even if not necessarily based on the image information, corresponding information is transmitted by voice or text communication. It is also possible to make 300 receive.
In this system, in particular, it is determined that the intruder is an illegal intruder only after it is found through the above-mentioned image matching process that the intruder does not match with any person qualified to enter the surveillance area. Is notified to the restraint agency, the reliability itself of the notification is maintained very high even in the latter method in which the image information is not necessarily transmitted to the notification receiving device 300.
Further, in the system of the above embodiment, it is assumed that the general public line is used as the transmission lines PT1 and PT2, but the selection is arbitrary, and another dedicated line may be used. Alternatively, a wireless line can be used.
Also, in the configuration of the concentrator 200, in the system of the above embodiment, when the image matching unit 206 outputs the signal NM indicating the disagreement, the second notification control unit 211 is immediately activated, Although the fact that there has been an illegal intruder has been notified to the restraint organization, in addition to this, for example, a telephone automatic transmission means capable of automatically executing a call processing to a designated telephone is provided in the concentrator. If the signal NM indicating the disagreement is output, the automatic telephone calling means automatically makes a call to a telephone installed in advance in the monitoring area to set a certain value. Only when the response from the intruder is not obtained to this call even after the elapse of time, the second notification control unit 21
It is also possible to adopt a configuration in which 1 is activated. Normally, a person qualified to enter the building can respond to such a call without hesitation, and even if the accuracy of the above image matching processing is quite high, the imaging conditions of the intruder happened to be bad. In such a case (for example, when the face portion cannot be imaged), it is difficult to perform accurate matching, and so on.

With regard to the above, it is possible to combine these with one device part each.
In addition to the notification function in the above-described mode, the terminal device 100 also (1) notifies the concentrator device 200 of the monitoring information of the monitoring area at each preset time through a timer or the like.
(2) When the monitoring canceling operation is performed (the reset signal R is sent) to the monitoring control unit 103, the concentrator 200 is notified of the monitoring information of the monitoring area.
(3) Regardless of whether the surveillance control unit 103 is set or reset, when the security sensor 101 detects an intruder, the surveillance information of the surveillance area is reported to the concentrator 200.
(4) When a power failure occurs, the monitoring information of the monitoring area is notified to the concentrator 200.
(5) When power is restored, the concentrator 200 is notified of the monitoring information of the monitoring area.
It is also possible to combine the functions of
Each can have an arbitrary configuration according to the actual conditions of the monitored area.
Further, in the embodiment, the ID number information is used as the identification information of each monitoring area, and the corresponding information such as the address and the telephone number is based on the ID number information.
At 00, the ID related information database 210 is searched, and this is added to the notification information.
In addition, for example, information indicating these addresses and telephone numbers is directly used as the identification information, and this information is sent from the terminal device and added to the notification information, or the ID is used.
Even if the number information is used, for example, a simple table provided in the concentrator is used to convert this into related information such as each applicable address and telephone number, and this converted information is converted into the same notification information. It can also be added. That is, in the crime prevention monitoring system according to the present invention, it is not essential to dispose the ID related information database 210.
Besides, various modifications are possible without being limited to the configuration of the above-described embodiment without departing from the spirit of the crime prevention monitoring system.
As described above, according to the present invention, when there is an intruder in the surveillance area, the image information of the intruder is collected through the surveillance camera and the image information is registered in advance. The intruder is an illegal intruder only when it is found that the intruder does not match any of the qualified persons entering the surveillance area by checking the image information of the qualified person admission to the surveillance area. As a result, since the fact is notified to the restraint agency, the probability of false alarms is extremely low, and a highly reliable notification process as a security monitoring system can be carried out quickly and reliably.
