Description

  The present invention relates to a crime prevention monitoring system in an apartment house having a common entrance hall, a common hallway, a common stairs, or an elevator.

  Conventionally, in a monitoring system using a security camera in an apartment house such as an apartment, as shown in Patent Documents 1 to 3, an administrator monitors images of each security camera sent to an administrator room, or There are some which monitor such images by transferring them to the monitor of an external security company.

  However, in a monitoring system that performs monitoring in the administrator room, since there is usually one administrator, there is a high possibility that an intruder will be overlooked.If the administrator is on patrol or absent at night, the security camera image will be displayed. It is only recorded. Furthermore, in small and medium-sized condominiums, it is difficult for managers to reside in terms of management costs.

  For this reason, a system that transfers the image of a security camera to a monitoring room of an external security contractor and performs monitoring may be adopted, but usually, a monitoring person simultaneously monitors a plurality of apartment houses, It is often difficult to respond quickly to suspicious individuals or emergencies.

  With respect to such a problem, in the technique of Patent Document 3, even if the administrator overlooks an intruder, or the administrator is in patrol or absent at night, the crime prevention is effective, and the administrator An invention relating to a crime prevention system that can reduce the harm of the person as much as possible and can promptly warn or capture an intruder is disclosed.

  However, in the above-described conventional example, it is necessary to provide a monitoring device or an information board with a monitor in each dwelling unit, which is a heavy burden in terms of construction costs and the like. In particular, the technology of Patent Document 3 expects a monitoring effect by a resident by distributing an image of a security camera inside a dwelling unit of an apartment house. However, in a small and medium-sized apartment house, the number of units is small and effective. poor.

  In addition, the conventional example requires constant remote monitoring, and the burden of running costs such as labor costs is enormous, making it difficult to apply to small apartments and is not practical. . Furthermore, there is a problem that the system becomes complicated, for example, it is necessary to control the imaging of the security camera by a remote operation terminal in order to protect the resident's privacy.

  In recent crimes in housing complexes, so-called stalker crimes targeting specific residents are increasing. In order to prevent such stalking crimes, a system that remotely unlocks and locks the doors of the common entrance doors in response to a call from the common entrance hall is already common. It is necessary that the dwelling unit of the specific resident is difficult to be specified. Furthermore, residents of apartment houses are highly aware of privacy, and residents may not be acquainted with each other. For example, coexistence of crime prevention functions and privacy is a major issue.

  The biggest problem among them is that the number of single-person households has been increasing in recent years, and in particular, the number of single-person households has increased, and stalker crimes targeting such single women are increasing. In general, large-scale high-rise condominiums are well equipped with security, and crime prevention facilities as described in the above patent documents are being completed. However, in general, single women rarely live in such large-scale high-rise condominiums, and the majority live in small and medium-sized rental condominiums, and crime is increasing in such apartment buildings.

  On the other hand, even in Patent Document 3, which is characterized by providing a monitoring monitor in a dwelling unit and obtaining a monitoring effect, the expected effect cannot be sufficiently exerted in an apartment house with many single-person households that tend to be absent everyday. There is a problem.

  The present invention solves the above-mentioned problems, and the object of the present invention is to ensure the safety of the resident while securing the safety of the common area with a simple operation for the resident at a low price in a small and medium-sized apartment house. In order to provide a security system that takes privacy into consideration and to ensure safety when the resident returns home, especially at night, the resident can check the state of the common area in advance when returning home. It is intended to provide a crime prevention monitoring system for collective housing that can perform remote monitoring only during times when it is necessary to ensure the safety of residents in common areas, such as when going out or going out.

In order to achieve the above object, the first configuration of the crime prevention monitoring system for collective housing according to the present invention is a plurality of crime prevention measures provided in common areas such as common entrance hall and common corridor, common staircase, and common elevator of the collective housing. a camera, is provided in the common entrance hall, a video monitor capable of displaying an image captured by the security camera, provided in the common entrance hall, and authentication information obtaining means you get the credentials, previously registered a registration information storage means for storing registration information has been user, before and authentication information acquired by Ki認 card information acquisition means, whether said registration information registration information stored in the storage unit matches determination means for determining, by the determination unit, before and Ki認 card information acquired credentials by obtaining means, when the stored registered information is determined to match in the registration information storage means, said Prevention It includes a start control means for activating the camera and the video monitor, the common entrance hall, the common corridor, shared stairs, and alarm panel provided in common areas, such as common elevator and the in each dwelling, the alarm panel Is a security mode signal transmission means for transmitting any one of a security mode setting signal for setting a security mode at least by a switch operation and a security mode release signal for canceling the security mode setting, and one of the alarm panels The security mode setting display of each alarm panel is displayed by the security mode setting signal received from the security mode signal transmission means, and the security mode release signal received from the security mode signal transmission means of any of the alarm panels Security mode display means for hiding the security mode setting display is provided.

Moreover, the second configuration of the security monitoring system for an apartment house according to the present invention includes a plurality of security cameras provided in a shared part such as a shared entrance hall and a shared hallway, a shared staircase, and a shared elevator of the apartment house. A video monitor provided in the entrance hall and capable of displaying an image captured by the security camera, an authentication information acquisition means provided in the common entrance hall for acquiring authentication information, and preregistered user registration information A registration information storage means for storing; a determination means for determining whether or not the authentication information acquired by the authentication information acquisition means matches the registration information stored in the registration information storage means; and When it is determined that the authentication information acquired by the authentication information acquisition unit matches the registration information stored in the registration information storage unit, the security camera and the video And activation control means for activating the monitor, the selected from a plurality of security cameras, made from the user security camera that is Installation on stroke path up to the front door of each dwelling unit, different stroke with CCTV group storage means for storing a security camera group set for each route, if it is determined that the user of by RiTadashi regulations to the determining means, stored in said security camera group storage the and a security camera group extracting means for extracting a security camera set on stroke path of authorized user, the activation control means on the stroke path of the user of the legitimate extracted by-proof prisoners camera group extracting means The security camera belonging to the security camera group and the video monitor are activated.

  Here, the “security camera group” refers to a security camera installed on the path of each dwelling unit. The common entrance hall, shared corridor, shared staircase, elevator, etc. that are each part or area of the apartment are shared. Among the plurality of security cameras arranged in the section, the security cameras required for security monitoring are selected for each dwelling unit.

According to the first and second configurations of the security monitoring system for an apartment house according to the present invention, only a registered user can travel the path from the common entrance hall to the entrance door of the user's residence with a security camera. Since the captured video can be viewed and remote monitoring can be performed only when the resident is required to ensure the safety of the resident in the common area, such as when he / she goes home, the monitoring efficiency is remarkably increased and is inexpensive. Monitoring costs can be realized. Furthermore, since the state of the shared section can be confirmed in advance when returning home, etc., since remote monitoring is not performed when it is judged unnecessary, the resident's own privacy can be sufficiently secured.

  Moreover, since the video of the security camera is transferred only when remote monitoring is required in this system, video recording is not always necessary, and there is an advantage in terms of cost reduction in that respect.

Moreover, according to the 1st structure of the security monitoring system for apartment houses which concerns on this invention, a security mode is made into a common entrance hall, each process route, and the alarm panel in each dwelling unit by setting and canceling at least a security mode.

13 is a second communication unit comprising a transmitting means for transmitting a security mode signals emitted by turning ON / OFF the warning precepts and emergency switch 11 of the alarm panel 8 to the remote terminal unit.

  The user / dwelling unit information DB 6 stores a group of security cameras provided on each path from the common entrance hall 2 of the housing complex to the entrance door of each dwelling unit 3 of the user who is a registered resident. Also serves as a security camera group storage means.

  Here, the “process route” is composed of each part or area of an apartment house that can be a path from the common entrance hall 2 provided in the residential area of the apartment house to the entrance / exit of the entrance door of each apartment 3 of the apartment house. Is done. Accordingly, the “stroke route” includes, for example, the common entrance hall 2, the common hallway, and the common part 10 such as the common stairs / elevator.

  The “security camera group 1” is a security camera 1 installed on the travel route of each dwelling unit 3, and includes a common entrance hall 2, a common corridor, a common staircase, an elevator, etc., which are each part / area of the housing complex. Among the plurality of security cameras 1 arranged in the common part 10, the security camera 1 necessary for security monitoring is selected for each dwelling unit 3.

Further, the control unit 7 calculates the process of the user stored in the user / dwelling unit information DB 6 also serving as the security camera group storage unit from the registration information of the regular user determined by the determination unit including the control unit 7. A security camera group extracting means for extracting a group of security cameras on the route also serves as a security camera group extracting means, and an activation control means comprising the control unit 7 is a security camera on the user's process route extracted by the security camera group extracting means. The security camera 1 and the video monitor 4 belonging to the first group are activated.

  Note that the control unit 7 according to the present embodiment also serves as the above-described determination unit, activation control unit, and security camera group extraction unit, but is not limited to this, and the control unit is independently provided for each unit. It may be configured.

  The authentication device 5 confirms the operator who operates the video monitor 4. The management device 14 controls the security camera 1, the alarm panel 8, the authentication device 5 and the like, and has a video / signal transfer function for remote monitoring. In the present system, the security camera 1 is not capturing images normally, that is, in a standby state. Therefore, no image is displayed on the video monitor 4.

In the above configuration, the operation of the monitoring system when the resident returns home will be described with reference to the flowchart of FIG. First, in step S _1, resident activates previously owned (lent) is an IC card, an authentication device 5 provided in the shared entrance hall 2 with key other. The control section 7, when the authentication information acquired by the authentication apparatus 5, and the registration information stored in a Subscriber-dwelling information DB6 is determined to match in step S _2, control section 7 by extracting the security camera 1 group on stroke path from the shared entrance hall 2 of the user stored in the registered information or RaToshi for user-dwelling unit information DB6 the entrance door of the dwelling unit 3, management device 14 In response to the signal, imaging of the security camera 1 is started (step S ₃ ).

  Note that the security camera 1 that starts imaging may be limited to the necessary route route from the common entrance hall 2 to the entrance door of the resident's dwelling unit 3, but if necessary, the imaging of all the security cameras 1 may be performed. It is also possible to perform control to start the process.

At the same time, the captured image is displayed on the image monitor 4 in the common entrance hall 2 (step S ₄ ). The display on the video monitor 4 may be displayed by switching the security cameras 1 sequentially, or the screen of the video monitor 4 may be divided into a plurality of images displayed by the security cameras 1.

  Residents can check the presence of suspicious persons in the route from the common entrance hall 2 to the entrance door of their own dwelling unit 3 or the common area 10 as a whole by the video displayed on the video monitor 4. I can do it. If there is no suspicious person, you can return to your dwelling unit 3 safely.

If the presence of a suspicious person is recognized, the resident can turn on the warning / emergency switch 11 of the alarm panel 8 provided in the common entrance hall 2. In step S _5, when the alarm and emergency switch 11 is turned ON, the operation signal of the warning and emergency switch 11 via the management apparatus 14 is sent to the external security contractors of the monitoring device (step S _6), The image of the security camera 1 of the housing complex is displayed on the monitoring monitor of the monitoring device, and the monitor starts monitoring from that point (step S ₁₁ ).

  A speaker may be installed in the shared unit 10 in advance, and an announcement to that effect may be made to inform the suspicious person or resident that the alarm mode has been entered. Alternatively, it is also effective to change the illumination of the shared unit 10 in advance between the normal mode and the warning mode, and to increase the illuminance of the shared unit 10 during the warning.

When the warning / emergency switch 11 is turned on in the warning mode in step S ₇ , the warning mode is controlled by the timer of the control unit 7, so that a preset resident can return from the common entrance hall 2 to his / her dwelling unit 3. When a sufficient time has elapsed to reach a safe level, the video monitor 4 and the security camera 1 are automatically turned off (steps S ₈ and S ₉ ). At that time, the remote monitor ends the monitoring.

In the unlikely event that the resident feels a danger in the common area 10 or the dwelling unit 3, all alarm panels 8 sound by turning on the emergency mode with the alarm / emergency switch 11 of the alarm panel 8 ( Step S ₁₀ ) threatens the suspicious person, informs the remote supervisor that the emergency is occurring (step S ₁₁ ), and can quickly take necessary and appropriate measures such as reporting to the police.

Incidentally, in the above step S _5, when the alarm and emergency switch 11 has not been turned ON, the timer control of the control unit 7 determines that the safe mode, the shared preset return home residents entrance hall 2 When a sufficient time has passed to reach the dwelling unit 3 safely, the video monitor 4 and the security camera 1 are turned off automatically (steps S ₈ and S ₉ ).

  Next, a security monitoring system when going out will be described. The resident's outing time is usually from morning to daytime, and the risk of encountering a suspicious person in the common area 10 is low, but this crime prevention monitoring system can provide safety assurance when going out. First of all, the resident can display the security mode type display means 12 provided on the alarm panel 8 in the dwelling unit 3 so that the security mode of the security monitoring system is currently “safe mode”, “warning mode” and “emergency mode”. You can check which crime prevention mode is selected.

  If "emergency mode" is displayed on the crime prevention mode type display means 12 provided on the alarm panel 8, an emergency has occurred in the common area 10, so that you will be involved in danger without leaving the dwelling unit 3. You can report to the police. Further, if “warning mode” is displayed on the crime prevention mode type display means 12 provided on the alarm panel 8, it is understood that there is another resident in the shared unit 10. When the “safety mode” is displayed on the crime prevention mode type display means 12 provided on the alarm panel 8 (that is, not operating), it can be determined that there is no particular danger. However, when going out at night or when a suspicious person appears in the surrounding area, by turning on the “warning mode” switch by the warning / emergency switch 11 provided on the alarm panel 8 when leaving the dwelling unit 3, Since remote monitoring can be started, safety is further increased.

Next, with reference to FIGS. 4 and 5, security on stroke path of the control by Ri-size the section 7 of constant has been authorized user registration information or RaToshi for user-dwelling unit information DB6 stored in the user An operation for extracting a group of cameras will be described.

  As shown in FIG. 5, the user / dwelling unit information DB 6 stores the room number of the dwelling unit 3 and the name of the user who lives in the dwelling unit 3, and is associated with the floor number and position of the room number of the dwelling unit 3. Whether or not each security camera 1 is activated for each area is preset. As a result, all the security cameras 1 provided on the travel route from the common entrance hall 2 of the apartment building to the entrance door of the specific user's dwelling unit 3 are activated for a specific user to monitor the travel route. I can do it.

  For example, room number 201 is set to activate a group of security cameras installed in a part or area of an apartment house with a mark “◯” in FIG. That is, the area of “2nd floor” marked with “○” in the common entrance hall 2 (“Hall” in the table of FIG. 5) and the shared hall 10 (shared area in the table of FIG. 5) such as the shared hallway and shared stairs. Only the security camera 1 installed in (part or region) is activated, and the security camera 1 installed in the “1st floor” or “3rd floor” area marked with “x” is not activated. The activation control is as follows.

In step S ₂₁ in FIG. 4, reading information of the user ID information (unit number and name) is acquired by the authentication device 5. Next, in step S ₂₂ , the determination means comprising the control unit 7 collates the dwelling unit 3 with the name data. Control unit 7, in step S _23, it is determined whether the record matched is in the user-dwelling unit information DB 6, the determination information (permission signal) in step S ₂₄ if there is a record that matches the activation signal In step S ₂₅ , determination information (permission signal) is returned to the authentication device 5.

Next, in step S _26, and acquires the camera activation pattern of security camera 1 corresponding to the relevant dwelling unit 3 (see FIG. 5) from the user-dwelling unit information DB 6, it identifies the security camera 1 corresponding in step S _27. In step S ₂₈ , an activation signal is transmitted to the video monitor 4 and each security camera 1. If there is no record that matches the returns a determination information (inhibit signal) to the authentication device 5 in step S ₂₉ in step S _23.

  According to the said structure, only the user registered beforehand can visually recognize the image | video which imaged the process route from the common entrance hall 2 to the entrance door of the user's dwelling unit 3 with the security camera 1, and a resident Since remote monitoring can be performed only during the time when it is necessary to ensure the safety of the resident in the shared unit 10, such as when returning home or going out, the monitoring efficiency is remarkably increased and an inexpensive monitoring cost can be realized. Furthermore, since the state of the shared unit 10 can be confirmed in advance when returning home, etc., since remote monitoring is not performed when it is judged unnecessary, the resident's own privacy can be sufficiently secured.

  In addition, since the video of the security camera 1 is transferred only when remote monitoring is required in this system, video recording is not always necessary, and there is an advantage in terms of cost reduction.

  Moreover, it is possible to select an alarm type for each crime prevention mode with different risk levels and urgency in the safety mode, the alert mode, and the emergency mode, and display it on the alarm panel 8 in each dwelling unit 3 to share the crime prevention information. I can do it.

  In addition, it is possible to respond appropriately from the outside according to the degree of danger and urgency by transmitting to the external remote terminal means for each crime prevention mode having a different degree of danger and urgency in the safety mode, warning mode and emergency mode.

In addition, it is possible to appropriately select the security camera 1 to be started from the authentication information, efficient operation can be.

  This provides a crime prevention system that is inexpensive for small and medium-sized apartments and that is easy for the resident to ensure the safety of the common area 10 and also takes into account the resident's privacy, especially at night. In order to ensure safety when a person goes home, the resident can check the state of the shared unit 10 in advance when returning home, etc., and it is possible to ensure the safety of the resident in the shared unit when returning home or going out Remote monitoring can be performed only during the required time.

  As an application example of the present invention, the present invention can be applied to a crime prevention monitoring system in an apartment house having a common part such as a common entrance hall, a common hallway, a common stairs or an elevator.
