Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a security system, and particularly relates to a security terminal (hereinafter, simply referred to as a terminal) such as a security sensor or a surveillance camera and a monitoring center device, which are connected to an Internet Protocol (hereinafter, referred to as IP). The present invention relates to a security system that is connected via a network and performs security processing such as security status change and alarm processing on the monitoring center device side.
[0002]
[Prior art]
A conventional security system is configured by connecting a security center device of a security company and a security device arranged in a security object to be guarded via an appropriate communication line such as a public telephone line or an IP network. ing. The security device is connected to various security sensors such as a heat ray sensor, and a terminal such as a security status setting device for setting the security status of the security area, and the security device is connected to each security set by the security status setting device. Various security processes are performed based on the security status of the area, detection signals from security sensors, and the like.
[0003]
However, in recent years, security sensors and surveillance cameras have been treated as network terminals using network technology, particularly internet technology. For example, Japanese Patent Laying-Open No. 2002-44858 discloses that a gas leak detector and a router are housed in a single housing and connected to a security center via the Internet.
[0004]
Japanese Patent Application Laid-Open No. 2002-77881 discloses that a surveillance camera is used as an Internet terminal device to transmit image data to a monitoring device at predetermined time intervals or at predetermined time intervals, or to control a monitoring camera from a monitoring device. A technique has been disclosed that enables transmission of image data.
[0005]
Further, Japanese Patent Application Laid-Open No. 2002-58076 discloses that a sensor or the like is connected to a home network, and when an incident is detected, the incident is transmitted to a server of a predetermined organization via the Internet.
[0006]

[0007]
[Problems to be solved by the invention]
However, JP-A-2002-44858 only describes a gas leak detector, and describes a case where a security sensor such as a hot-wire sensor or an open detection sensor that detects that a door or a window is opened is used. It has not been.
Since the gas leak detector and the security sensor have different meanings of detection signals or how to handle them, it is not possible to use the technology disclosed in JP-A-2002-44858 as it is in a security system having a security sensor. Can not.
[0008]
That is, when a gas leak detector detects a gas leak, it outputs a detection signal, and the detection signal as it is means an alarm, that is, occurrence of an abnormality, but a detection signal is output for a security sensor such as a heat ray sensor. Just because it is, it is not an alert. For example, the hot-wire sensor outputs a detection signal when detecting a movement of a person, but the alarm is generated only when the guarded area is in a guarded state, and when the guarded area is in a released state. However, even if a detection signal is output from the security sensor, it cannot be regarded as an alarm.
[0009]
Also, Japanese Patent Application Laid-Open No. 2002-77881 only describes a surveillance camera, and does not describe that a security sensor is treated as a terminal device of a network.
[0010]
Further, Japanese Patent Application Laid-Open No. 2002-58076 discloses a technology for connecting a security sensor to a home network. However, whether or not an abnormality has occurred is determined in the home network. If the security sensor is detected, only that the fact is transmitted via the Internet, and the fact that the security sensor itself is used as a terminal of the network is not described.
[0011]
As described above, in the above-mentioned prior art document, the security sensor is also treated as a terminal of the network, and in that case, how the security processing such as the change of the security state of each security area and the processing of alerting is performed. It is not described whether it is better to do it.
[0012]
Therefore, the present invention treats security devices such as security sensors and surveillance cameras as IP network terminals, and performs security processing in a monitoring center device based on data transmitted in packets from those terminals. It is an object of the present invention to provide a security system that can perform security.
[0013]

The security processing is performed by recognizing the set security state.
According to a third aspect of the present invention, in the security system according to the second aspect, the security state setting of the security sensor by the security state setting device includes a level of a host name of the security sensor, a level of a unique name, a level of an arrangement area, and a level of a security property. It can be performed for each level.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the invention will be described with reference to the drawings. In the embodiment described below, the IP network is assumed to be IPV4 (Internet Protocol Version 4), but the present invention can be applied to IPV6 (Internet Protocol Version 6) scheduled in the future. It is.
[0015]
FIG. 1 is a diagram showing an embodiment of a security system according to the present invention, in which 1 is an IP network, 2 is a router, 3a, 3b,..., 3n are terminals, and 10 is a security center device. In addition, when the terminal device is simply referred to without specifying the type of the terminal device, the terminal device 3 is described.
[0016]
In the security system according to the present invention, as shown in FIG. 1, a security center device 10 operated by a security company, a router 2, and terminals 3a to 3n (n is a natural number) are arranged via an IP network 1. The security property side is connected to each other. Although only one security center device 10 is shown in FIG. 1, a plurality of security center devices 10 may be provided.
[0017]
If the security center device 10 is a server, the security property is a client.
[0018]
The router 2 and the terminals 3 a to 3 n are arranged in a security property that has a security contract with a security company that operates the security center device 10. The router 2 is connected to the IP network 1, and the router 2 is connected to at least one terminal. The terminal device includes at least a security sensor, and it is also possible to use a security state setting device, a monitoring camera, or the like that sets the security state of the security area from the security state to the release state or vice versa.
[0019]
In the security system shown in FIG. 1, a unique IP address is assigned to each of the security center device 10, the router 2, and the terminals 3a to 3n, and a domain name is assigned to the security center device 10. , A sub-domain name including the domain name of the security center device 10 is assigned to the router 12, and a host name is assigned to each of the terminals 3a to 3n.
[0020]
The host name of each of the terminals 3a to 3n includes a unique name, a name indicating the area where the terminal is located, and a hierarchy including a subdomain name of the router and a domain name of the security center device. It is made. This is a major feature of this security system. An example will be described.
[0021]
Now, suppose that the security property is Mr. A's home, a security sensor a and a security sensor b are placed in the living room, a security sensor c is placed in the bedroom, and a surveillance camera and security status setting device are placed in the entrance. Suppose you have been. The security sensors a, b, and c, the surveillance camera, and the security status setting device are terminals.
[0022]
In this case, a hierarchical structure of a tree structure as shown in FIG. 2 is provided, and a security center device is at the top, which can be said to be a security company level. Below that level is the security property level, and Mr. A's house is also at this level.
[0023]
Below the security property level is the area level for each security property. Therefore, as shown in FIG. 2, the living room, bedroom, and entrance area of Mr. A's house are at a level below the security property of Mr. A's house. The level of the terminal 3 is below the level of each area of the security property. The level of the terminal 3 is the lowest hierarchy.
[0024]
Therefore, in this case, the sub-domain name of the router 2 and the host name of each terminal 3 are given so that the hierarchical structure shown in FIG. 2 can be represented. For example, if the domain name of the security center device 10 is “keibi”, the sub-domain name of the router 2 is that the router 2 is under the control of the security center device 10 and the security property of Mr. A's house For example, "a.keibi" may be used to indicate that Here, “a” indicates that it is a security property of Mr. A's house.
[0025]
The host name of the sensor a is located under the router 2 and is located in the living room area, and is, for example, “sena.lib. a.keibi ". Here, “sena” indicates that the sensor is a, and “lib” indicates that the living room is used. This is the same in the following. From the host name, it can be seen that the terminal device 3 is a unique name of “sensor a” and that the terminal device is located in an area called “living room”.
[0026]
Similarly, the host name of the sensor b is, for example, “senb.lib.a.keibi”, the host name of the sensor c is, for example, “senc.sin.a.keibi”, and the host name of the monitoring camera is, for example, “Cam.gen.a.keibi” and the host name of the security status setting device may be “rim.gen.a.keibi”, for example. Note that “sin” indicates a bedroom, “cam” indicates a surveillance camera, “gen” indicates an entrance, and “rim” indicates a security state setting device.
[0027]
As described above, the sub-domain name of the router 2 is assumed to be a domain name of the security center device 10 and a name capable of identifying a security property, and the host name of the terminal 3 is assigned to the sub-domain name of the router 2. In this way, the name of the security center device 10, the subdomain name of the router 2 under the security center device 10, The host name of the terminal device 3 under the router 2 has a hierarchical structure.
[0028]
As a result, the host name of the terminal device 3 is assigned to which area of the security property with a unique name, the router 2 is located at a level above the security device, and the security center device 10 is located at a level above the router 2. There is a hierarchy that there is.
[0029]
Hereinafter, a case will be described in which the domain name of the security center device 10, the subdomain name of the router 2, and the host name of the terminal device 3 are as described above.
[0030]
Next, the configuration of the terminal device 3 will be described.
When the terminal device 3 is a surveillance camera, a known configuration as disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 2002-77881 may be used. As a result, image data captured at predetermined time intervals or at predetermined time intervals can be transmitted to the security center device 10, and the person in charge of the security center device 10 can control the security camera from the security center device 10 as necessary. By controlling, image data can be transmitted. In the communication control unit of the surveillance camera, the IP address assigned to itself and the IP address of the security center device 10, which is the destination of data to be transmitted, are registered.
[0031]
FIG. 3 shows a configuration example when the terminal device 3 is a security sensor. The sensor head 4 is for detecting a predetermined state, and when the security sensor is a heat ray sensor, the sensor head 4 is for setting a pyroelectric element and an area for detecting movement of a person. It consists of a reflector and a Fresnel lens. Further, when the security sensor is an open detection sensor, the security sensor can be configured by a unit that can detect that a door or a window is opened, for example, a magnetic proximity switch including a magnet and a reed switch.
[0032]
The signal processing unit 5 determines whether a predetermined state has occurred based on a signal from the sensor head 4, and outputs a detection signal when it is determined that the predetermined state has occurred. For example, in the case of a hot-wire sensor, as is well known, when the output signal of the pyroelectric element is equal to or greater than a threshold, it is determined that a person has moved, and a detection signal is output. The same applies to other security sensors.
[0033]
The communication control unit 6 includes a CPU, an IC for performing communication according to the TCP / IP protocol, and the like. In the communication control unit 6, the IP address assigned to itself and the IP address of the security center device 10, which is the destination of the data to be transmitted, are registered.
[0034]
Then, when receiving the detection signal from the signal processing unit 5, the communication control unit 6 includes, in the data indicating that the predetermined state has been detected, the own IP address indicating the transmission source and the IP address of the security center device 10 as the destination. A packet with a header including an address is generated, and the packet is transmitted according to the TCP / IP protocol. This packet passes through the router 2 and is received by the security center device 10 via the IP network 1.
[0035]
Next, FIG. 4 shows a configuration example when the terminal device 3 is a security state setting device. The operation unit 7 is for setting a guard state for a guard area set for a security property. Generally, an operation for selecting a guard area and setting a guard state for the selected guard area are performed. One operation is to perform two operations, i.e., to perform the operation and to set the release state. However, there is also known an operation in which the above two operations can be performed by one operation. Various configurations of the operation unit 7 of the security state setting device are known, and any configuration may be used.
[0036]
Assuming that an operation for setting the alert state in the alert area A is performed on the operation unit 7, the operation detection processing unit 8 interprets the meaning of the operation. Therefore, in this case, the operation detection processing unit 8 recognizes that the alert state has been set in the alert area A. Then, the operation detection processing unit 8 passes data indicating the recognized content to the communication control unit 9.
[0037]
The communication control unit 9 includes a CPU, an IC that performs communication using the TCP / IP protocol, and the like, and registers an IP address assigned to itself and an IP address of the security center device 10 that is a destination of data to be transmitted. .
[0038]
Then, upon receiving the data from the operation detection processing unit 8, the communication control unit 9 attaches a header including the own IP address indicating the transmission source and the IP address of the security center device 10 as the destination to the data. A packet is generated, and the packet is transmitted according to the TCP / IP protocol. This packet passes through the router 2 and is received by the security center device 10 via the IP network 1.
[0039]
The case of Mr. A's house will be described. In such a general private house, in a security state setting device used for so-called home security, three types of a security button, a home security button, and a release button are provided in order to prevent erroneous operation. In many cases, only some operation buttons are provided. The alert button is a button operated when setting all alert areas to the alert state, and the release button is a button operated when setting all alert areas to the released state. The at-home guard button is a button for setting a part of the guard area where a person is present to a released state and setting the other unmanned guard areas to a guard state.
[0040]
In such a case, when the alert button of the operation unit 7 is operated, the operation detection processing unit 8 recognizes that the alert button has been operated, and generates data indicating that the alert button has been operated. The communication control unit 9 generates a packet in which the data is attached with a header including its own IP address indicating the transmission source and the IP address of the security center device 10 which is the destination, and Is transmitted in accordance with the TCP / IP protocol.
The same applies to the case where the release button or the home alert button is operated.
[0041]
Next, the configuration of the security center device 10 will be described. FIG. 5 is a diagram showing a configuration example of the security center device 10, in which 11 is a control unit, 12 is a monitor, 13 is an input unit, 14 is a storage unit, and 15 is a Domain Name System (Domain Name System: A reference numeral 16 denotes a WWW server (World Wide Web Server); 17 denotes a database server (hereinafter referred to as a DB server); and 18 denotes a communication control unit.
[0042]
The control means 11 performs security processing for each security property based on data received from the terminal device 3, security condition data for each security property registered in the DB server 17, and the like. The details will be described later.
[0043]
The monitor 12 is configured by a display device such as a color CRT, and the input unit 13 is configured by an input device such as a mouse or a keyboard. The storage means 14 is composed of a large-capacity storage device such as a hard disk device.
[0044]
The DNS server 15 is for obtaining the host name of the terminal 3 that has transmitted the data from the IP address of the transmission source attached to the received data by a method of name resolution. Since the DNS system, the DNS server, and the method of name resolution are well known, detailed description thereof will be omitted. However, in the security system shown in FIG. 1, the correspondence table between the IP address and the host name of the terminal 3 is stored in the router 2. Alternatively, another server (not shown) connected to the IP network 1 or a server (not shown) higher than the security center device 10 may have it.
[0045]
As is well known, the WWW server 16 is a server for exchanging information described in an HTML (Hyper Text Markup Language) format by an HTTP (Hyper Text Transfer Protocol) protocol.
[0046]
The communication control means 18 communicates with the terminal 3 disposed in the security property via the IP network 1 in accordance with the TCP / IP protocol.
[0047]
The DB server 17 is for registering various information on each security property. As information registered in the DB server 17, property information and security condition information are registered for each security property.
[0048]
The property information is information on security properties such as the property name, owner name, address, telephone number, and the like. In the security condition information, the correspondence between the IP address and the host name of each terminal 3 is registered, and at least the security state of the terminal 3 of the security sensor can be written.
[0049]
Further, the security condition information includes, for each security property, when it is determined that an abnormality has occurred, and when the terminal 3 has a surveillance camera, in which case the image data is stored in the surveillance camera. For example, information on conditions for performing security processing in the security center device 10, such as whether to instruct transmission of security information, is registered.
[0050]
FIG. 6 shows an example of such security condition information. The security condition information shown in FIG. 6 is an example of the security condition information in the case of Mr. A's house.
[0051]
In the security property column, information for identifying the security property is written. Here, since it is Mr. A's house, "Mr. A's house" is written.
[0052]
In the column of IP address, IP addresses are written for all the terminals arranged in the security property. In FIG. 6, the IP address column is blank, but as described above, a unique IP address is assigned to each terminal device. The address is to be written.
[0053]
In the host section, a name indicating the unique name of the terminal device among the host names of the respective terminal devices is written. This is referred to as a host unit in this specification.
[0054]
In the area section, a name indicating the name of the area where the terminal is located in the host name of each terminal is written. In this specification, this is called an area part.
[0055]
In the DNS section, a name for specifying a security property in the host name of each terminal is written. This is referred to as a DNS unit in this specification.
[0056]
In the case of Mr. A's house, the host name of the sensor a is “sena.lib.a.keibi”, in which “sena” is the unique name of the terminal, and “lib” is the name of the terminal. Since the name of the area is located and “a” is a name for specifying the security property, as shown in FIG. 6, the sensor a of the security condition information has the host unit, the area unit, and the DNS unit. , "Sena", "lib", and "a" are respectively written.
The same applies to other terminals.
[0057]
In the security condition information, a security status column is provided. When the terminal device is a security sensor, the current security status value is written in the security status column. Here, assuming that the security status value when the alert status is set is “1” and the security status value when the release status is set is “0”, the security status column of the sensor a in FIG. Is written, it is understood that the sensor a is currently set in the alert state. However, when the release state is set to the sensor a thereafter, the security state value is changed to “0”.
[0058]
The security status value in the security status column is changed by the control unit 11 of the security center device 10 by the data transmitted from the security status setting device, which is one of the terminal devices, or the mobile phone or the PDA terminal as described later. And the like, which is transmitted from the mobile information terminal device and instructs to change the security state. It should be noted that which terminal is the security sensor may be determined as a security sensor if the host unit includes the character “sen”.
[0059]
In FIG. 6, “×” is written in the column of the security status of the terminal device having the unique name “rim”, which indicates that the security status is not set for the terminal device.
[0060]
Furthermore, the security condition information that defines what kind of security processing should be performed on the security property of Mr. A's house is written in the security condition information. In FIG. 6, it is defined that when data indicating that an alarm has been issued is received from a security sensor set to the alert state, an abnormality has occurred, that is, an alarm has been issued.
[0061]
In FIG. 6, when data indicating that the security button has been operated is received from the security state setting device, the DNS unit sets the security sensor having the host name “a” to the security state, and sets the release button. If the DNS unit receives the data indicating that the operation has been performed, the DNS unit sets the security sensor having the host name of “a” to the release state, and if the data indicates that the home alert button has been operated, the area unit determines It is stipulated that only the security sensor having the host name “lib” be in the alert state.
[0062]
As security processing conditions, it is possible to write various security processing conditions such as, for example, when to instruct the monitoring camera to transmit image data.
[0063]
It should be noted that each item of the security processing condition is naturally set according to the intention of the security property, and can be changed as needed. Therefore, for example, when the security property instructs to change the guard area to be in the guard state at home guard, the guard processing condition is changed accordingly.
[0064]
Next, an example of the operation will be described. Again, considering the case of Mr. A's house, the security state setting device is assumed to have three operation buttons: a security button, a home security button, and a release button. It is also assumed that security processing conditions shown in FIG. 6 have been determined.
[0065]
(1) Operation when the security button of the security status setting device is operated
When the alert button of the security status setting device at Mr. A's house is operated, a packet of data indicating that the alert button has been operated is transmitted from the terminal. At this time, as described above, the IP address of the terminal device is assigned to the data as the source address, and the IP address of the security center device 10 is assigned to the data as the destination.
[0066]
The data passes through the router 2 and is received by the communication control means 18 of the security center device 10 via the IP network 1. Upon receiving the packet, the communication control unit 18 passes the data in the packet to the control unit 11 and passes the IP address of the transmission source of the packet to the DNS server 15. Then, the DNS server 15 obtains a host name corresponding to the IP address, and passes the obtained host name to the control unit 11.
[0067]
The control means 11 interprets the data received from the communication control means 18 to recognize the contents thereof, and refers to the security condition information of the DB server 17 based on the host name received from the DNS server, and Is recognized from which terminal of which security property, and what kind of processing should be performed by referring to the security processing condition of the security condition information. At this time, the control unit 11 stores the data in the storage unit 14 for each security property.
[0068]
In this case, the control unit 11 recognizes that the guard button of the guard state setting device in Mr. A's house has been operated, and based on the guard processing conditions shown in FIG. 6, the terminal whose DNS unit is “a”. The security status value "1" indicating that the security status has been set is written in the security status column of the security device, that is, the security sensor. As a result, the alert state is set for all the security sensors arranged in Mr. A's house.
[0069]
Thereafter, when data indicating that the sensor a, which is a terminal device of Mr. A's house, has detected a predetermined state is transmitted, the data is received by the security center device 10. Then, the host name of the terminal device is determined by the DNS server 15 of the security center device 10 and passed to the control means 11. Further, the control unit 11 recognizes the current security state of the terminal from the security condition information. In this case, the alert state value of the sensor a is “1”, and the control unit 11 recognizes that the sensor a is currently in the alert state.
[0070]
Therefore, in this case, the control unit 11 determines that an abnormality has occurred based on the security processing conditions. Then, the control means 11 displays on the monitor 12 the property information of the security property and the occurrence of the abnormality. Thereby, the person in charge of the security center device 10 can recognize which security property has an abnormality, and can dispatch a security guard to the security property.
[0071]
(2) Operation when the release button of the security status setting device is operated
When the release button of the security status setting device at Mr. A's house is operated, a packet of data indicating that the release button has been operated is transmitted from the terminal. At this time, as described above, the IP address of the terminal device is assigned to the data as the source address, and the IP address of the security center device 10 is assigned to the data as the destination.
[0072]
The data passes through the router 2 and is received by the communication control means 18 of the security center device 10 via the IP network 1. Upon receiving the packet, the communication control unit 18 passes the data in the packet to the control unit 11 and passes the IP address of the transmission source of the packet to the DNS server 15. Then, the DNS server 15 obtains a host name corresponding to the IP address, and passes the obtained host name to the control unit 11.
[0073]
The control means 11 interprets the data received from the communication control means 18 to recognize the contents thereof, and refers to the security condition information of the DB server 17 based on the host name received from the DNS server, and Is recognized from which terminal of which security property, and what kind of processing should be performed by referring to the security processing condition of the security condition information. At this time, the control unit 11 stores the data in the storage unit 14 for each security property.
[0074]
In this case, the control unit 11 recognizes that the release button of the security state setting device in Mr. A's house has been operated, and based on the security processing conditions shown in FIG. 6, the terminal whose DNS unit is “a”. A security status value "0" indicating that the release status has been set is written in the security status column of the security device, that is, the security sensor. Thereby, the release state is set for all the security sensors arranged in Mr. A's house.
[0075]
Thereafter, assuming that the sensor a, which is the terminal device of Mr. A's house, has transmitted data indicating that a predetermined state has been detected, the data is received by the security center device 10. Then, the host name of the terminal device is determined by the DNS server 15 of the security center device 10 and passed to the control means 11. Further, the control means 11 recognizes from the security condition information that the current security state value of the terminal is “0”, that is, the terminal is in the released state.
[0076]
Therefore, in this case, the control unit 11 does not determine that an abnormality has occurred, and ends the processing for the data.
[0077]
(3) Operation when the home alert button of the security status setting device is operated
When the home alert button of the security status setting device at Mr. A's home is operated, a packet of data indicating that the home alert button has been operated is transmitted from the terminal device. At this time, as described above, the IP address of the terminal device is assigned to the data as the source address, and the IP address of the security center device 10 is assigned to the data as the destination.
[0078]
The data passes through the router 2 and is received by the communication control means 18 of the security center device 10 via the IP network 1. Upon receiving the packet, the communication control unit 18 passes the data in the packet to the control unit 11 and passes the IP address of the transmission source of the packet to the DNS server 15. Then, the DNS server 15 obtains a host name corresponding to the IP address, and passes the obtained host name to the control unit 11.
[0079]
The control means 11 interprets the data received from the communication control means 18 to recognize the contents thereof, and refers to the security condition information of the DB server 17 based on the host name received from the DNS server, and Is recognized from which terminal of which security property, and what kind of processing should be performed by referring to the security processing condition of the security condition information. At this time, the control unit 11 stores the data in the storage unit 14 for each security property.
[0080]
In this case, the control unit 11 recognizes that the home guard button of the security status setting device at Mr. A's house has been operated, and based on the security processing conditions shown in FIG. Is written in the column of the security status of the terminal device, that is, the security sensor, which indicates that the security status has been set. Thus, the alert state is set only for the security sensor arranged in the living room of Mr. A's house.
[0081]
Thereafter, if it is assumed that the security sensor disposed in the living room of Mr. A's house has transmitted data indicating that a predetermined state has been detected, the security center device 10 receives the data. Then, the host name of the terminal device is determined by the DNS server 15 of the security center device 10 and passed to the control means 11. Further, the control means 11 recognizes from the security condition information that the current security state value of the security sensor is “1”, that is, the security sensor is in the security state.
[0082]
Therefore, in this case, the control unit 11 determines that an abnormality has occurred based on the security processing conditions. Then, the control means 11 displays on the monitor 12 the property information of the security property and the occurrence of the abnormality. Thereby, the person in charge of the security center device 10 can recognize which security property has an abnormality, and can dispatch a security guard to the security property.
[0083]
However, when data indicating that the area of the host name has detected a predetermined state from a security sensor other than “lib” is received, in this case, the security state value of the security sensor is “0”. Therefore, in this case, the control unit 11 does not determine that an abnormality has occurred, and ends the processing for the data.
[0084]
(4) Security status setting by a device other than the security status setting device
As is clear from the above description, since the security center device 10 performs communication using the TCP / IP protocol via the IP network, communication using the TCP / IP protocol via the IP network 1 is possible. If it is a device, it is possible to receive data from a device other than the terminal 3 arranged in the security property. Of course, in this case, the form of the data to be transmitted needs to be a form that can be recognized by the control unit 11 of the security center device 10.
[0085]
Therefore, in the security system shown in FIG. 1, a desired security state of the security sensor can be set from a mobile information terminal device such as a mobile phone or a PDA terminal. In that case, the security state can be set to the alert state or the release state by specifying the host part of the host name of the security sensor, and the security state can be set to the alert state or the release state by specifying the host name area. It is also possible to specify the DNS part of the host name and set it to the alert state or the release state. Furthermore, it is also possible to change the security state of the security sensor that sets the security state during home security.
[0086]
For example, assuming that the host unit of the host name of the security sensor is designated and set to the alert state, the control unit 11 of the security center device 10 is alert only to the security sensor including the host unit specified in the host name. If the state is set and the security state is set by specifying the area of the host name of the security sensor, the control unit 11 sets the security state to only the security sensor including the area specified by the host name. Assuming that the security state is set by specifying the DNS of the host name of the security sensor and setting the security state, the control unit 11 sets the security sensor including the DNS unit specified in the host name, that is, all the security sensors of the security property. Set the alert state for.
[0087]
【The invention's effect】
As described above, according to the present invention, security devices such as security sensors, surveillance cameras, and security status setting devices are treated as IP network terminals, and based on data transmitted from these terminals in packets. Thus, a security system that can perform security processing in the monitoring center device can be constructed.
[0088]
Further, according to this security system, the security status of the security sensor, which is a terminal device arranged in the security property, is indicated by various levels of the host name, in the case shown in FIG. The security level can be set at three levels, that is, the level of the DNS unit, and the security state can be set flexibly as compared with a conventional system in which security devices are arranged in security objects. That is, it is possible to construct a security system with high flexibility.
[0089]
Further, when it is necessary to change the security processing, the security processing condition in the security condition information registered in the DB server 17 only needs to be changed, so that the security processing can be easily changed. be able to.
