     Technical Problem 
     The known security devices and security systems disclosed in Patent Literatures 1 and 2 described above are effective in entrance monitoring or access control for houses and buildings where it is easy to define a security area, but are inapplicable to some outdoor places such as a shrine, a temple, a greenhouse, an anchorage of a ship such as a yacht or a boat, a parking lot, a bicycle-parking lot, and a freight terminal where intrusion can be made from anywhere, that is, there are innumerable intrusion paths, and it is impossible to define an intrusion section and set a range of the intrusion section because it is difficult to define the security area. 
     Further, some of the known security devices and security systems include a surveillance camera, but it is difficult to determine whether an intruder is present through continuous visual check of an image obtained from the surveillance camera, and it is therefore impossible to ensure a security level that allows detection at the point of occurrence of an abnormality.

     DESCRIPTION OF EMBODIMENTS 
     A description will be given below of an example of an embodiment of the present invention with reference to the accompanying drawings. 
     [Security Device] 
     A security device according to the present embodiment includes a plurality of detection means that detect a person, and controls a security status of a security target to a security-activated status or a security-deactivated status based on whether the person has been detected within a detection range of each of the detection means. 
     Hereinafter, examples of the “security target” described in the present embodiment include a “building” such as a “house”, an office (business office), a public facility, or an entertainment facility, a “structure” such as a shrine, a temple, or a greenhouse, and a “movable property” such as a vehicle including an automobile, a bicycle, and an armored cash transport car, or a ship including a yacht and a boat. 
     According to the present embodiment, a security area and a warning area are defined for the security target. The security area is an area where the inside of a building serving as the security target such as a house, an office (business office), a public facility, or an entertainment facility is placed under security. The warning area is an area around a building serving as the security target such as a house, an office (business office), a public facility, or an entertainment facility, a structure such as a shrine, a temple, or a greenhouse, or a movable property such as a vehicle including an automobile, a bicycle, and an armored cash transport car, or a ship including a yacht and a boat and is a warning area in the detection range of the detection means to be described later. 
     For example, for a house illustrated in  FIG. 3( a )  as an example of a security target  22 , the inside of the house is defined as a security area  23 , and the surroundings of the house are defined as a warning area  24 , as illustrated in  FIG. 3( d ) . For a shrine illustrated in  FIG. 3( b ) , an area where a main hall is placed is defined as the security area  23 , and the surroundings of the main hall are defined as the warning area  24 , as illustrated in  FIG. 3( d ) . For a ship such as a boat illustrated in  FIG. 3( c ) , an area where the ship is placed is defined as the security area  23 , and the surroundings of the ship are defined as the warning area  24 , as illustrated in  FIG. 3( d ) . Note that an area other than the security area  23  and the warning area  24  is defined as a non-warning area  25 . 
     Then, the security device according to the present embodiment is installed in the security area  23  and/or the warning area  24  to place the security target  22  under security. 
     Further, “security activation” described in the present embodiment includes processing of activating a conventionally known locking device to close a lock, processing of imaging a security status of the security target by an imaging means to be described later, and the like, and “security deactivation” includes processing of opening the lock. 
     1. First Embodiment of Security Device 
     A security device  1 A illustrated in  FIG. 1  includes a control device  2  that controls various types of information processing, and is installed in the security area  23  and/or the warning area  24 . A detection means  14 , a warning means  15 , and an imaging means  16  are connected to the control device  2 , and an external terminal  17  is further communicatively connected to the control device  2  over a communication network such as the Internet, a radio communication network adhering to a radio communication standard, or a wired communication network adhering to a wired communication standard, examples of the external terminal  17  including a user terminal such as a smartphone, a tablet terminal, a personal computer, or a mobile phone used by a user related to the security target  22 , and a service provider terminal such as a server device, a smartphone, a tablet terminal, a personal computer, or a mobile phone used or installed by a security service provider. 
     Examples of the detection means  14  include a conventionally known motion sensor, an RFID reader/writer, a photoelectric sensor, an ultrasonic sensor, and the like. According to the present embodiment, as illustrated in  FIG. 4 , the security device  1 A includes a plurality of detection means  14 . 
     In the example illustrated in  FIG. 4( a ) , a person is detected by three detection means  14 A,  14 B,  14 C installed in the security area  23  and/or the warning area  24 . Further, a detection range  26  of a first detection means  14  and a detection range  26  of a second detection means  14  overlap each other to form overlapping detection ranges  27   a ,  27   b . In the detection range  26  of each detection means, a detection signal constant in intensity level is output. 
     In the example illustrated in  FIG. 4( b ) , the detection means  14 A,  14 B have a plurality of detection ranges  26   a ,  26   b ,  26   c  different in detection intensity from each other. Over the detection range  26   a , for example, a detection signal having an intensity level of “1” is output, over the detection range  26   b , for example, a detection signal having an intensity level of “2” is output, and over the detection range  26   c , for example, a detection signal having an intensity level of “3” is output. 
     Note that, in the configuration illustrated in  FIG. 1 , the detection means  14  is provided within the security device  1 A, or alternatively, may be provided separately from the security device  1 A and attached to the security device  1 A. 
     Examples of the warning means  15  include a conventionally known warning buzzer, a light emitting device, and the like. When a determination unit  10  (to be described later) determines that there is an intrusion abnormality based on a result of determination of whether a suspicious person has intruded into the security target  22  with the security target  22  placed under the security-activated status or the security-deactivated status, the warning buzzer sounds a warning, and the light emitting device emits light, so as to provide notification of the abnormality. 
     Examples of the imaging means  16  include a conventionally known surveillance camera, a web camera, and the like. The imaging means  16  records, for the security target  22 , the security status of the security area  23  and the warning area  24  as a still image or a moving image. 
     As illustrated in  FIG. 1 , the control device  2  includes an information transmission/reception unit  3 , a storage unit  8 , a detection order comparison unit  9 , the determination unit  10 , a person detection position recognition unit  11 , a detection condition setting unit  12 , and a security status control unit  13 . 
     The information transmission/reception unit  3  transmits and receives information to and from the detection means  14 , the warning means  15 , the imaging means  16 , and the external terminal  17 . According to the present embodiment, the information transmission/reception unit  3  includes a detection signal acquisition unit  4 , a determination result notification unit  5 , an image information transmission unit  6 , and a warning instruction unit  7 . 
     The detection signal acquisition unit  4  acquires s detection signal output by the detection means  14 . 
     The determination result notification unit  5  notifies the external terminal  17  of a result of determination that a suspicious person has intruded into the security target  22  performed by the determination unit  10  (to be described later). The user or the security service provider who owns and uses the external terminal  17  can know the security status of the security target  22  and can take a corresponding measure. 
     The image information transmission unit  6  transmits information on a security state of the security target  22  to the external terminal  17 . For example, image information containing the still image or moving image obtained as a result of capturing the security area  23  and the warning area  24  of the security target  22  by the imaging means  16  is transmitted to the external terminal  17 . The user or the security service provider who owns and uses the external terminal  17  can know the security status of the security target  22  from the transmitted information on the security state of the security target  22  and can take a corresponding measure. 
     When the determination unit  10  (to be described later) determines that there is an intrusion abnormality based on a result of determination of whether a suspicious person has intruded into the security target  22  with the security target  22  placed under the security-activated status or the security-deactivated status, the warning instruction unit  7  instructs the warning means  15  to provided notification of the above-described abnormality. 
     The storage unit  8  stores various kinds of information such as a security-activation or security-deactivation detection order of the detection means for comparison processing performed by the detection order comparison unit  9  (to be described later), and image information obtained as a result of capturing the security area  23  and the warning area  24  of the security target  22  by the imaging means  16 . 
     The detection order comparison unit  9  performs a comparison to determine whether the detection order of the detection means  14  that have detected a person coincides with the security-activation or security-deactivation detection order of the detection means prestored in the storage unit  8 . This comparison processing will be described in the following determination processing 1. 
     The determination unit  10  performs the following determination processing. 
     (Determination Processing 1) 
     The security status of the security target  22  is determined based on a result of the comparison, performed by the detection order comparison unit  9 , to determine whether the detection order of the detection means  14  that have detected the person coincides with the security-activation or security-deactivation detection order of the detection means prestored in the storage unit  8 . 
     In the configurations illustrated in  FIGS. 4( a )  and  5 , information on the security-activation or security-deactivation detection order of the detection means indicating “first: the detection means  14 A, second: a combination of the detection means  14 A and the detection means  14 B, third: the detection means  14 B, fourth: a combination of the detection means  14 B and the detection means  14 C, and fifth: the detection means  14 C” is prestored in the storage unit  8 . 
     In  FIG. 5( a ) , when the security status of the security target  22  is set to the security-activated status or the security-deactivated status, and a certain person moves on a movement path  28   a  through the security area  23  or the warning area  24 , the person is detected in the order of the detection range  26  of the detection means  14 A, the overlapping detection range  27   a  between the detection means  14 A and the detection means  14 B, the detection range  26  of the detection means  14 B, the overlapping detection range  27   b  between the detection means  14 B and the detection means  14 C, and the detection range  26  of the detection means  14 C. 
     The detection order comparison unit  9  performs a comparison to determine whether the above-described detection order of the detection means  14  that have detected the person on the movement path  28   a  coincides with the security-activation or security-deactivation detection order of the detection means prestored in the storage unit  8 . 
     Because, with the security status of the security target  22  illustrated in  FIG. 5( a )  set to the security-activated status or the security-deactivated status, the above-described detection order of the detection means  14  that have detected the person on the movement path  28   a  coincides with the above-described security-activation or security-deactivation detection order of the detection means prestored in the storage unit  8 , the determination unit  10  determines that there is no abnormality in entry processing or no abnormality in exit processing. 
     On the other hand, in  FIG. 5( b ) , when the security status of the security target  22  is set to the security-activated status or the security-deactivated status, and a certain person moves on a movement path  28   b  through the security area  23  or the warning area  24 , the person is detected in the order of the detection range  26  of the detection means  14 B, the overlapping detection range  27   b  between the detection means  14 B and the detection means  14 C, and the detection range  26  of the detection means  14 C. When a certain person moves through the security area  23  or the warning area  24  on a movement path  28   c , the person is detected in the detection range  26  of the detection means  14 C. 
     The detection order comparison unit  9  performs a comparison to determine whether the above-described detection order of the detection means  14  that have detected the person on the movement paths  28   b ,  28   c  coincide with the security-activation or security-deactivation detection order of the detection means prestored in the storage unit  8 . 
     Because, with the security status of the security target  22  illustrated in  FIG. 5( b )  is set to the security-activated status or the security-deactivated status, the above-described detection order of the detection means  14  that have detected the person on the movement paths  28   b ,  28   c  does not coincide with the security-activation or security-deactivation detection order of the detection means prestored in the storage unit  8 , the determination unit  10  determines that there is an intrusion abnormality. 
     The person detection position recognition unit  11  acquires a detection signal for the detection range  26  of the detection means  14  that have detected the person at a time t n , and performs processing of recognizing of which detection means  14  the person is present within the detection range  26  based on the intensity of the detection signal. 
     In the configuration illustrated in  FIG. 6( a ) , the plurality of detection means  14 A,  14 B illustrated in  FIG. 4( b )  are installed in the security area  23  and/or the warning area  24 , and the security status of the security target  22  is set to the security-activated status or the security-deactivated status. For example, when the detection means  14 A,  14 B output the detection signals at the time t n  as illustrated in  FIG. 6( b ) , the person detection position recognition unit  11  performs processing of recognizing the detection position of the person as follows. 
     Neither of the detection means  14 A,  14 B outputs the detection signal at a time t 1 , so that the person detection position recognition unit  11  determines that no person is present in the security area  23  or the warning area  24 . 
     The detection means  14 A outputs the detection signal with the detection signal intensity of “1” at a time t 2 , so that the person detection position recognition unit  11  determines that the person is present in the detection range  26   a  of the detection means  14 A. 
     The detection means  14 A outputs the detection signal with the detection signal intensity of “2” at a time t 3 , so that the person detection position recognition unit  11  determines that the person is present in the detection range  26   b  of the detection means  14 A. 
     The detection means  14 A outputs the detection signal with the detection signal intensity of “3” at a time t 4 , so that the person detection position recognition unit  11  determines that the person is present in the detection range  26   c  of the detection means  14 A. 
     The detection means  14 A outputs the detection signal with the detection signal intensity of “2” at a time t 5 , so that the person detection position recognition unit  11  determines that the person is present in the detection range  26   b  of the detection means  14 A. 
     At a time t 6 , the detection means  14 A outputs the detection signal with the detection signal intensity of “2”, and the detection means  14 B outputs the detection signal with the detection signal intensity of “1”, so that the person detection position recognition unit  11  determines that the person is present in the overlapping detection range  27   a  between the detection range  26   b  of the detection means  14 A and the detection range  26   a  of the detection means  14 B. 
     At a time t 7 , the detection means  14 A outputs the detection signal with the detection signal intensity of “1”, and the detection means  14 B outputs the detection signal with the detection signal intensity of “1”, so that the person detection position recognition unit  11  determines that the person is present in the overlapping detection range  27   b  between the detection range  26   a  of the detection means  14 A and the detection range  26   a  of the detection means  14 B. 
     At a time t 8 , the detection means  14 A outputs the detection signal with the detection signal intensity of “1”, and the detection means  14 B outputs the detection signal with the detection signal intensity of “2”, so that the person detection position recognition unit  11  determines that the person is present in the overlapping detection range  27   c  between the detection range  26   a  of the detection means  14 A and the detection range  26   b  of the detection means  14 B. 
     The detection means  14 B outputs the detection signal with the detection signal intensity of “2” at a time t 9 , so that the person detection position recognition unit  11  determines that the person is present in the detection range  26   b  of the detection means  14 B. 
     In the configuration illustrated in  FIG. 6 , when the above-describing processing is repeatedly performed, a fact that a certain person has moved on a movement path  28   d  through the security area  23  or the warning area  24  is recognized based on a time-series evaluation of the detection signal intensity of the detection means  14 . 
     The detection condition setting unit  12  performs processing of setting a detection interval of each detection means based on whether a person has been detected by the detection means  14 . In this case, a first detection means is associated with a second detection means adjacent to the first detection means, and when the first detection means detects the person, the second detection means associated with the first detection means is also controlled to have its detection interval set in conjunction with the first detection means. 
     In the configuration illustrated in  FIG. 7( a ) , the plurality of detection means  14 A,  14 B,  14 C illustrated in  FIG. 4( a )  are installed in the security area  23  and/or the warning area  24 , and the security status of the security target  22  is set to either the security-activated status or the security-deactivated status. The detection means  14 A is associated with the detection means  14 B adjacent to the detection means  14 A, the detection means  14 B is associated with the detection means  14 A,  14 C adjacent to the detection means  14 B, and the detection means  14 C is associated with the detection means  14 B adjacent to the detection means  14 B. 
     When a certain person moves on a movement path  28   e  through the security area  23  or the warning area  24 , the detection condition setting unit  12  performs processing of setting the detection intervals of the detection means  14 A,  14 B,  14 C as follows. 
     The non-warning area  25  (state A) is located out of the detection ranges of the detection means  14 A,  14 B,  14 C, so that the detection condition setting unit  12  sets the detection interval of each detection means to a “long” state such as 10 to 20 seconds. 
     In the detection range  26  (state B) of the detection means  14 A, the detection means  14 A detects the person, so that the detection condition setting unit  12  sets the detection interval of the detection means  14 A to a “short” state such as 2 to 4 seconds. In this case, the detection means  14 B,  14 C do not detect the person, but the detection means  14 B is associated with the detection means  14 A, so that the detection condition setting unit  12  also sets, to the “short” state, the detection interval of the detection means  14 B adjacent to the detection means  14 A that has detected the person. 
     In the overlapping detection range  27   a  (state C) between the detection means  14 A and the detection means  14 B, the detection means  14 A,  14 B detect the person. In this case, the detection means  14 C does not detect the person, but the detection means  14 C is associated with the detection means  14 B, so that the detection condition setting unit  12  also sets, to the “short” state, the detection interval of the detection means  14 C adjacent to the detection means  14 B that has detected the person. 
     In the detection range  26  (state D) of the detection means  14 B, the detection means  14 B detects the person. In this case, the detection means  14 A,  14 C do not detect the person, but the detection means  14 A,  14 C are associated with the detection means  14 B, so that the detection condition setting unit  12  maintains, in the “short” state, the detection intervals of the detection means  14 A,  14 C adjacent to the detection means  14 B that has detected the person. 
     In the overlapping detection range  27   b  (state E) between the detection means  14 B and the detection means  14 C, the detection means  14 B,  14 C detect the person. In this case, the detection means  14 A does not detect the person, but the detection means  14 A is associated with the detection means  14 B, the detection condition setting unit  12  maintains the detection interval of the detection means  14 A in the “short” state. 
     In the detection range  26  (state F) of the detection means  14 C, the detection means  14 C detects the person. In this case, the detection means  14 A does not detect the person, so that the detection condition setting unit  12  sets the detection interval of the detection means  14 A to the “long” state. Further, the detection means  14 B does not detect the person, but the detection means  14 B is associated with the detection means  14 C, so that the detection condition setting unit  12  maintains the detection interval of the detection means  14 B in the “short” state. 
     The non-warning area  25  (state G) is located out of the detection ranges of the detection means  14 A,  14 B,  14 C, so that the detection condition setting unit  12  sets the detection intervals of the detection means  14 B,  14 C to the “long” state. 
     Further, when the determination unit  10  determines that there is an intrusion abnormality based on a result of the above-described determination processing, the detection condition setting unit  12  sets the detection intervals of the detection means  14 A,  14 B,  14 C to the “short” state. 
     Further, in the configuration illustrated in  FIG. 7 , two types of detection intervals, the “long” and “short” states, are available, but various types of detection intervals of the detection means may be set. For example, when a detection interval of a “middle” state of 5 to 9 seconds is defined, and the first detection means have its detection interval set to the “short” state, the second detection means associated with the first detection means can have its detection interval set to the “middle” state. 
     The processing performed by the detection condition setting unit  12  allows the plurality of detection means  14  to detect the person in the security area  23  or the warning area  24  while changing the detection interval, so that the position and movement direction of the person can be more accurately recognized. 
     The above-described processing performed by the person detection position recognition unit  11  allows the position of a certain person in the security area  23  or the warning area  24  to be recognized, and the processing performed by the detection condition setting unit  12  allows the movement path of the person to be confirmed with a detection frequency of the detection means  14  increased. 
     For example, as illustrated in  FIG. 12( a ) , the security device  1 A that includes the plurality of detection means  14  to form a plurality of overlapping detection ranges  27  is installed in the security area  23  and/or the warning area  24 , and the person detection position recognition unit  11  and the detection condition setting unit  12  perform their respective processing, so that it is possible to recognize of which detection means  14  the certain person is present within the detection range  26  and how the certain person moves. 
     When the comparison performed by the detection order comparison unit  9  shows that the detection order of the detection means  14  that have detected the person coincides with the security-activation or security-deactivation detection order of the detection means, the security status control unit  13  controls the security status of the security target  22  from the security-deactivated status to the security-activated status or from the security-activated status to the security-deactivated status. 
     As described above, according to the present embodiment, a building such as a house, an office (business office), a public facility, or an entertainment facility, a structure such as a shrine, a temple, or a greenhouse, or a movable property such as a vehicle including an automobile, a bicycle, and an armored cash transport car, or a ship including a yacht and a boat is set as the security target, and the security device can be installed in the security area and/or the warning area defined for the security target. This makes it possible to perform not only conventional detection of whether a suspicious person has intruded into a building, but also detection of whether the suspicious person has intruded into the warning area defined outside the building. 
     Further, the above-described determination processing on the security status of the security target facilitates the confirmation of whether a suspicious person has intruded from the warning area into the security area, and allows the security status of the security target to be automatically controlled to the security-activated status based on various detection patterns of the detection means, so that it is possible to prevent the activation of security from being forgotten and make security higher. 
     2. Second Embodiment of Security Device 
     A security device  1 B illustrated in  FIG. 2  includes an RFID reception device  19  having a reader/writer function in addition to the components of the security device  1 A illustrated in  FIG. 1 . Further, the control device  2  of the security device  1 B includes an RFID identification unit  20  in addition to the components of the control device  2  of the security device  1 A illustrated in  FIG. 1 . The same components as the components of the security device  1 A illustrated in  FIG. 1  are denoted by the same reference numerals, and no description will be given below of such components. 
     The RFID reception device  19  communicates with the RFID tag  18  over radio waves and receives identification information transmitted by an RFID tag  18 . To the communication system of the communications with the RFID tag  18 , an active mode or a passive mode is applicable. A communication distance may be several 10 m for both of the modes. 
     In the configuration illustrated in  FIG. 2 , the RFID reception device  19  is provided within the security device  1 B, or alternatively, may be provided separately from the security device  1 B and attached to the security device  1 B. Further, the RFID reception device  19  may be provided for each detection means  14 . 
     The storage unit  8  stores RFID identification information for use in verification that is used by the RFID identification unit  20  to identify the RFID tag  18 . 
     The RFID identification unit  20  performs processing of identifying the RFID tag  18  by searching the RFID identification information for use in verification stored in the storage unit  8  for identification information that coincides with the identification information on the RFID tag  18  received by the RFID reception device  19 . 
     The determination unit  10  performs the following determination processing in addition to the above-described determination processing 1. 
     (Determination Processing 2) 
     A determination is performed as to whether a suspicious person has intruded into the security target  22  based on whether the detection means  14  has detected a person within the detection range  26  and whether the RFID reception device  19  has received the identification information on the RFID tag  18  or whether the RFID identification unit  20  has identified the RFID tag  18 . 
     In the configuration illustrated in  FIG. 9( a ) , the storage unit  8  stores information on the security-deactivation detection order of the detection means indicating “first: the detection means  14 A”, and information on the security-activation detection order of the detection means “first: the detection means  14 B, second: the detection means  14 A”. 
     In  FIG. 9( a ) , when the security status of the security target  22  is set to the security-activated status, and a user  29  moves to the warning area  24  with the RFID tag  18 , the detection means  14 A detects the user  29 . Further, the RFID reception device  19 A receives the identification information on the RFID  18 , and the RFID identification unit  20  performs processing of identifying the RFID tag  18 . 
     When the above-described comparison processing performed by the detection order comparison unit  9  shows that the detection order of the detection means  14  that have detected the user  29  coincides with the security-deactivation detection order of the detection means prestored in the storage unit  8 , and the RFID identification unit  20  has identified the RFID  18  based on the identification information on the RFID tag  18  received by the RFID reception device  19 , the determination unit  10  determines that there is no abnormality in entry processing based on the result of the comparison performed by the detection order comparison unit  9  and the result of the recognition processing on the RFID  18  performed by the RFID identification unit  20 . In this case, the security status control unit  13  performs processing of setting the security status of the security target  22  to the security-deactivated status. 
     After the security is deactivated, the position of the user  29  in the security area  23  or the warning area  24  can be recognized through the above-described processing performed by the person detection position recognition unit  11 , and the movement path of the user  29  can be confirmed through the processing of increasing the detection frequency of the detection means  14  performed by the detection condition setting unit  12 . 
     Further, the determination result notification unit  5  notifies the external terminal  17  of the result of the determination performed by the determination unit  10  that there is no abnormality in entry processing, and the image information transmission unit  6  transmits, to the external terminal  17 , the image information containing the still image or moving image obtained as a result of capturing the security area  23  and the warning area  24  of the security target  22  by the imaging means  16 , so that the security service provider who owns and uses the external terminal  17  can know the security status of the security target  22 . 
     Note that when the image information transmission unit  6  transmits the image information to the external terminal  17 , the identification information on the RFID tag  18  may be associated with the image information. In this case, as illustrated in  FIG. 2 , the identification information on the RFID tag  18  is displayed together with the image captured by the user  29  using the external terminal  17 , so that the service provider can confirm the owner of the RFID tag  18 . 
     For example, as illustrated in  FIG. 12( b ) , in a facility having a plurality of security areas  23 , when the security device  1 B including the detection means  14  and the RFID reception device  19  installed in each security area  23  and the warning area  24  defined between the security areas  23 ,  23 , and the determination processing by the determination unit  10 , the processing by the person detection position recognition unit  11 , and the processing by the detection condition setting unit  12  are performed, it is possible to recognize of which detection means  14  a person who has entered from an entrance gate  30  is present within the detection range  26  or how the person moves, and the identification information on the RFID tag  18  is displayed together with the image captured by the user  29  using the external terminal  17 , so that the service provider can confirm the owner of the RFID tag  18 . 
     With the security status of the security target  22  set to the security-deactivated status as illustrated in  FIG. 9( a ) , when the user  29  moves from the warning area  24  to the non-warning area  25 , the user  29  is detected in the order of the detection range  26  of the detection means  14 B and the detection range  26  of the detection means  14 A. When the above-described comparison processing performed by the detection order comparison unit  9  shows that the detection order of the detection means that have detected the user  29  coincides with the security-activation detection order of the detection means prestored in the storage unit  8 , and the RFID tag  18  is located outside the communication range of the RFID reception device  19 , the determination unit  10  determines that there is no abnormality in exit processing based on the result of the comparison performed by the detection order comparison unit  9  and the result of the recognition processing on the RFID tag  18  performed by the RFID reception device  19 . In this case, the security status control unit  13  performs processing of setting the security status of the security target  22  to the security-activated status. 
     On the other hand, with the security status of the security target  22  set to the security-activated status, the determination unit  10  determines that there is an intrusion abnormality in the following cases. 
     (1) A case where, with the security status of the security target  22  set to the security-activated status, the comparison performed by the detection order comparison unit  9  shows that the detection order of the detection means  14  that have detected a person does not coincide with the security-deactivation detection order of the detection means stored in the storage unit  8 . 
     This corresponds to a case where the person has intruded into the security area  23  or the warning area  24  through one of a plurality of intrusion paths. For example, this corresponds to a case where, in the configuration illustrated in  FIG. 9( a ) , the person has been detected not on the path corresponding to the security-deactivation detection order of the detection means “first: the detection means  14 A” but in the detection range  26  of the detection means  14 B. 
     (2) A case where, with the security status of the security target  22  set to the security-activated status, the comparison performed by the detection order comparison unit  9  shows that the detection order of the detection means  14  that have detected the person coincides with the security-deactivation detection order of the detection means stored in the storage unit  8 , but the RFID reception device  19  has not received the identification information on the RFID tag  18 . 
     This corresponds to a case where the person carries no RFID tag  18 . 
     (3) A case where the comparison performed by the detection order comparison unit  9  shows that the detection order of the detection means  14  that have detected the person coincides with the security-deactivation detection order of the detection means stored in the storage unit  8 , but the RFID identification unit  20  has failed to identify the RFID tag  18 . 
     This corresponds to a case where the person carries the RFID tag  18 , but the communications with the RFID reception device  19  have failed. 
     (4) A case where, with the security status of the security target  22  set to the security-deactivated status, the RFID reception device  19  has not received the identification information on the RFID tag  18 , and the comparison performed by the detection order comparison unit  9  shows that the detection order of the detection means  14  that have detected the person does not coincide with the security-activation detection order of the detection means stored in the storage unit  8 . 
     This corresponds to a case where the person has intruded into the security area  23  or the warning area  24  through one of the plurality of intrusion paths, and the person carries no RFID  18 . For example, this corresponds to a case where, with the security status of the security target  22  (a boat or an armored cash transport car) illustrated in  FIGS. 9( b ) and 9( c )  set to the security-deactivated status, a suspicious person has intruded into the warning area  24  without carrying the RFID tag  18 , and the detection means  14  have detected the suspicious person. 
     When it is determined that there is an intrusion abnormality, it is possible to recognize the position of the suspicious person in the security area  23  or the warning area  24  through the above-described processing performed by the person detection position recognition unit  11  or to track the suspicious person with the detection frequency of the detection means  14  increased through the processing performed by the detection condition setting unit  12 . 
     Further, the determination result notification unit  5  notifies the external terminal  17  of the result of the determination performed by the determination unit  10  that there is an intrusion abnormality, and the image information transmission unit  6  transmits, to the external terminal  17 , the image information containing the still image or moving image obtained as a result of capturing the security area  23  and the warning area  24  of the security target  22  by the imaging means  16 , so that the user or the security service provider who owns and uses the external terminal  17  can immediately know the security status of the security target  22  and can take a corresponding measure. 
     Further, when the result of the determination performed by the determination unit  10  shows that there is an intrusion abnormality, the warning instruction unit  7  instructs the warning means  15  to provide notification of the above-described abnormality. The warning means  15  provides notification of the abnormality as described above. 
     As described above, according to the present embodiment as well, a building such as a house, an office (business office), a public facility, or an entertainment facility, a structure such as a shrine, a temple, or a greenhouse, or a movable property such as a vehicle including an automobile, a bicycle, and an armored cash transport car, or a ship including a yacht and a boat is set as the security target, and the security device can be installed in the security area and/or the warning area defined for the security target. This makes it possible to perform not only conventional detection of whether a suspicious person has intruded into a building, but also detection of whether the suspicious person has intruded into the warning area defined outside the building. 
     Further, the above-described determination processing on the security status of the security target facilitates the confirmation of whether a suspicious person has intruded from the warning area into the security area, and allows the security status of the security target to be automatically controlled to the security-activated status based on various detection patterns of the detection means, so that it is possible to prevent the activation of security from being forgotten and make security higher. 
     [Security Processing by Security Device] 
     A flow of security processing of the security device  1 A illustrated in  FIG. 1  and a flow of security processing of the security device  1 B illustrated in  FIG. 2  will be described with reference to  FIGS. 8 to 11 . 
     1. Security Processing Pattern A 
     In a security processing pattern A illustrated in  FIGS. 8( b ) and 10( a ) , the determination unit  10  performs the above-described determination processing 1. 
     (S 101 ) With a house set as the security target  22 , the security device  1 A (not illustrated) and the detection means  14 A are installed in the house that is the security area  23 , the detection means  14 B is installed at an entrance that is the warning area  24 , and the security status of the security target  22  is set to the security-deactivated status. Further, the storage unit  8  of the security device  1 A stores information on the security-activation detection order of the detection means indicating “first: the detection means  14 A, second: the detection means  14 B”. 
     (S 102 ) The detection means  14 A,  14 B detect a family member (user  29 ) in their respective detection ranges  26 . 
     (S 103 ) The detection order comparison unit  9  performs a comparison to determine whether the detection order of the detection means  14  that have detected the user  29  coincides with the security-activation detection order of the detection means stored in the storage unit  8 . 
     (S 104 ) When the user  29  goes out and moves on a movement path  28   f  through the security area  23  and the warning area  24 , the user  29  is detected in the order of the detection range  26  of the detection means  14 A, the overlapping detection range  27  between the detection means  14 A and the detection means  14 B, and the detection range  26  of the detection means  14 B. 
     Because a result of the comparison processing on the detection order performed by the detection order comparison unit  9  shows that the detection order of the detection means  14  that have detected the user  29  on the movement path  28   f  coincides with the security-activation detection order of the detection means stored in the storage unit  8 , the determination unit  10  determines that there is no abnormality in exit processing. 
     The security status control unit  13  performs processing of setting the security status of the security target  22  to the security-activated status (for example, transition to a monitoring mode by the external terminal  17 ). Subsequently, the processing proceeds to a security processing pattern B to be described later. 
     (S 105 ) On the other hand, in  FIG. 8( b ) , when a suspicious person intrudes into the house, the suspicious person is detected in the order of the detection range  26  of the detection means  14 B, the overlapping detection range  27  between the detection means  14 A and the detection means  14 B, and the detection range  26  of the detection means  14 A. 
     Because a result of the comparison processing on the detection order performed by the detection order comparison unit  9  shows that the detection order of the detection means  14  that have detected the suspicious person does not coincide with the security-activation detection order of the detection means stored in the storage unit  8 , the determination unit  10  determines that there is an intrusion abnormality. 
     The determination result notification unit  5  notifies the external terminal  17  of the result of the determination performed by the determination unit  10 . Further, the image information transmission unit  6  transmits, to the external terminal  17 , image information containing the still image or moving image obtained as a result of capturing the security status of the security area  23  and warning area  24  of the security target  22  by the imaging means  16 . The user or the security service provider who owns and uses the external terminal  17  can know the security status of the security target  22  and can take a corresponding measure. 
     (S 106 ) The warning instruction unit  7  instructs the warning means  15  to output a warning. The warning buzzer sounds a warning, and the light emitting device emits light, so as to provide notification of the abnormality. In addition, the position of the suspicious person in the security area  23  or the warning area  24  is recognized through the above-described processing performed by the person detection position recognition unit  11 , and the detection frequency of the detection means  14  is increased through the processing performed by the detection condition setting unit  12 , so as to track the suspicious person. 
     2. Security Processing Pattern B 
     Also in a security processing pattern B illustrated in  FIGS. 8( c ) and 10( b ) , the determination unit  10  performs the above-described determination processing 1. The storage unit  8  of the security device  1 A stores information on the security-deactivation detection order of the detection means indicating “first: the detection means  14 B, second: the detection means  14 A”. The security status of the security target  22  is set to the security-activated status in the above-described S 104 . 
     (S 107 ) The detection means  14 A,  14 B detect a family member (user  29 ) in their respective detection ranges  26 . 
     (S 108 ) The detection order comparison unit  9  performs a comparison to determine whether the detection order of the detection means  14  that have detected the user  29  coincides with the security-deactivation detection order of the detection means stored in the storage unit  8 . 
     (S 109 ) When the user  29  comes back home and moves on a movement path  28   g  through the security area  23  and the warning area  24 , the user  29  is detected in the order of the detection range  26  of the detection means  14 B, the overlapping detection range  27  between the detection means  14 A and the detection means  14 B, and the detection range  26  of the detection means  14 A. 
     Because a result of the comparison processing on the detection order performed by the detection order comparison unit  9  shows that the detection order of the detection means  14  that have detected the user  29  on the movement path  28   g  coincides with the security-deactivation detection order of the detection means stored in the storage unit  8 , the determination unit  10  determines that there is no abnormality in entry processing. 
     The security status control unit  13  performs processing of setting the security status of the security target  22  to the security-deactivated status (for example, clear the monitoring mode by the external terminal  17 ). Subsequently, the processing proceeds to the above-described security processing pattern A. 
     (S 110 ) On the other hand, when the suspicious person remains in the warning area  24  (for example, a state where the suspicious person is loitering in the warning area  24 ), the detection means  14 B detects the suspicious person, and when the suspicious person intrudes into the security area  23  without being detected by the detection means  14 B, the detection means  14 A detects the suspicious person. Because a result of the comparison processing on the detection order performed by the detection order comparison unit  9  shows that the detection order of the detection means  14  that have detected the suspicious person does not coincide with the security-deactivation detection order of the detection means stored in the storage unit  8 , the determination unit  10  determines that there is an intrusion abnormality. 
     The determination result notification unit  5  notifies the external terminal  17  of the result of the determination performed by the determination unit  10 . Further, the image information transmission unit  6  transmits, to the external terminal  17 , image information containing the still image or moving image obtained as a result of capturing the security status of the security area  23  and warning area  24  of the security target  22  by the imaging means  16 . The user or the security service provider who owns and uses the external terminal  17  can know the security status of the security target  22  and can take a corresponding measure. 
     (S 111 ) The warning instruction unit  7  instructs the warning means  15  to output a warning. The warning buzzer sounds a warning, and the light emitting device emits light, so as to provide notification of the abnormality. In addition, the position of the suspicious person in the security area  23  or the warning area  24  is recognized through the above-described processing performed by the person detection position recognition unit  11 , and the detection frequency of the detection means  14  is increased through the processing performed by the detection condition setting unit  12 , so as to track the suspicious person. 
     3. Security Processing Pattern C 
     In a security processing pattern C illustrated in  FIGS. 9 and 11 ( a ), the determination unit  10  performs determination processing 2. 
     (S 201 ) A ship such as a yacht or a boat is set as the security target  22 , the detection means  14 A,  14 B illustrated in  FIG. 4( a )  and the security device  1 B including RFID reception devices  19 A,  19 B are installed at an anchorage that is the warning area  24 , and the security status of the security target  22  is set to the security-activated status. Further, the owner (user  29 ) of the ship such as a yacht or a boat carries the RFID tag  18 . The storage unit  8  of the security device  1 B stores information on the security-deactivation detection order of the detection means “first: the detection means  14 A”. 
     (S 202 ) The detection means  14 A,  14 B detect the user  29  in their respective detection ranges  26 . 
     (S 203 ) The detection order comparison unit  9  performs a comparison to determine whether the detection order of the detection means  14  that have detected the user  29  coincides with the security-deactivation detection order of the detection means stored in the storage unit  8 . 
     (S 204 ) When the comparison performed by the detection order comparison unit  9  shows that the detection order of the detection means  14  that have detected the user  29  coincides with the security-deactivation detection order of the detection means stored in the storage unit  8  (S 203 : Y), the RFID identification device  19  performs processing of receiving the identification information on the RFID tag  18 . In the configuration illustrated in  FIG. 9( a ) , the RFID identification device  19 A performs processing of receiving the identification information on the RFID tag  18 . 
     (S 205 ) When the RFID identification device  19 A receives the identification information on the RFID  18  (S 204 : Y), the RFID identification unit  20  performs processing of identifying the RFID tag  18  by searching the RFID identification information for use in verification stored in the storage unit  8  for identification information that coincides with the identification information on the RFID tag  18  received by the RFID reception device  19 A. 
     (S 206 ) When the RFID identification unit  20  identifies the RFID  18  based on the identification information on the RFID tag  18  received by the RFID reception device  19 A (S 205 : Y), the determination unit  10  determines that there is no abnormality in entry processing based on the result of the comparison performed by the detection order comparison unit  9  and the result of the recognition processing on the RFID  18  performed by the RFID identification unit  20 . In this case, the security status control unit  13  performs processing of setting the security status of the security target  22  to the security-deactivated status. Subsequently, the processing proceeds to a security processing pattern D to be described later. 
     After the security is deactivated, the position of the user  29  in the security area  23  or the warning area  24  can be recognized through the above-described processing performed by the person detection position recognition unit  11 , and the movement path of the user  29  can be confirmed through the processing of increasing the detection frequency of the detection means  14  performed by the detection condition setting unit  12 . 
     Further, the determination result notification unit  5  notifies the external terminal  17  of the result of the determination performed by the determination unit  10  that there is no abnormality in entry processing, and the image information transmission unit  6  transmits, to the external terminal  17 , the identification information on the RFID tag  18  with the identification information on the RFID tag  18  associated with the image information containing the still image or moving image obtained as a result of capturing the security status of the security area  23  and warning area  24  of the security target  22  by the imaging means  16 , so that the security service provider who owns and uses the external terminal  17  can know the security status of the security target  22  and can confirm the owner of the RFID tag  18 . 
     (S 207 ) On the other hand, with the security status of the security target  22  set to the security-activated status, the determination unit  10  determines that there is an intrusion abnormality in the following cases. 
     (1) A case where the comparison performed by the detection order comparison unit  9  shows that the detection order of the detection means  14  that have detected the person does not coincide with the security-deactivation detection order of the detection means stored in the storage unit  8  (S 203 : N). 
     This corresponds to a case where the person has been detected in the detection range  26  of the detection means  14 B, that is, a case where the person has intruded into the warning area  24  through one of the plurality of intrusion paths. 
     (2) A case where the comparison performed by the detection order comparison unit  9  shows that the detection order of the detection means  14  that have detected the person coincides with the security-deactivation detection order of the detection means stored in the storage unit  8 , but the RFID reception device  19  has not received the identification information on the RFID tag  18  (S 203 : Y, S 204 : N). 
     This corresponds to a case where the person carries no RFID tag  18 . 
     (3) A case where the comparison performed by the detection order comparison unit  9  shows that the detection order of the detection means  14  that have detected the person coincides with the security-deactivation detection order of the detection means stored in the storage unit  8 , but the RFID identification unit  20  has failed to identify the RFID tag  18  (S 203 : Y, S 204 : Y, S 205 : N). 
     This corresponds to a case where the person carries the RFID tag  18 , but the communications with the RFID reception device  19  have failed. 
     (S 208 ) The determination result notification unit  5  notifies the external terminal  17  of the result of the determination performed by the determination unit  10 . Further, the image information transmission unit  6  transmits, to the external terminal  17 , image information containing the still image or moving image obtained as a result of capturing the security status of the security area  23  and warning area  24  of the security target  22  by the imaging means  16 . The user or the security service provider who owns and uses the external terminal  17  can know the security status of the security target  22  and can take a corresponding measure. 
     (S 209 ) The warning instruction unit  7  instructs the warning means  15  to output a warning. The warning buzzer sounds a warning, and the light emitting device emits light, so as to provide notification of the abnormality. In addition, the position of the suspicious person in the warning area  24  is recognized through the above-described processing performed by the person detection position recognition unit  11 , and the detection frequency of the detection means  14  is increased through the processing performed by the detection condition setting unit  12 , so as to track the suspicious person. 
     4. Security Processing Pattern D 
     Also in the security processing pattern D illustrated in  FIGS. 9 and 11 ( b ), the determination unit  10  performs the above-described determination processing 2. The storage unit  8  of the security device  1 B stores information on the security-activation detection order of the detection means indicating “first: the detection means  14 A, second: the detection means  14 B”. The security status of the security target  22  is set to the security-deactivated status in the above-described S 206 . 
     (S 210 ) The detection means  14 A,  14 B detect the user  29  in their respective detection ranges  26 . 
     (S 211 ) The RFID identification device  19  performs processing of receiving the identification information on the RFID tag  18 . 
     (S 212 ) When the RFID identification device  19 A has not received the identification information on the RFID  18  because the user  29  has left (S 211 : N), that is, when the user  29  has moved from the warning area  24  to the non-warning area  25  to bring the RFID tag  18  outside the communication range of the RFID reception device  19 A, the detection order comparison unit  9  performs a comparison to determine whether the detection order of the detection means  14  that have detected the user  29  coincides with the security-activation detection order of the detection means stored in the storage unit  8 . 
     (S 213 ) When the comparison performed by the detection order comparison unit  9  shows that the detection order of the detection means  14  that have detected the user  29  coincides with the security-activation detection order of the detection means stored in the storage unit  8  (S 212 : Y), the determination unit  10  determines that there is no abnormality in exit processing based on the result of the comparison performed by the detection order comparison unit  9  and the result of the processing of receiving the RFID tag  18  performed by the RFID reception device  19 A. In this case, the security status control unit  13  performs processing of setting the security status of the security target  22  to the security-activated status. Subsequently, the processing proceeds to the security processing pattern C. 
     (S 214 ) On the other hand, with the security status of the security target  22  set to the security-activated status, the determination unit  10  determines that there is an intrusion abnormality in the following case.
         A case where the RFID reception device  19  has not received the identification information on the RFID tag  18  (S 211 : N), and the comparison performed by the detection order comparison unit  9  shows that the detection order of the detection means  14  that have detected the person does not coincide with the security-activation detection order of the detection means stored in the storage unit  8  (S 212 : N)       

     This corresponds to a case where the person has intruded into the security area  23  or the warning area  24  through one of the plurality of intrusion paths, and the person carries no RFID  18 . For example, this corresponds to a case where, with the security status of the security target  22  (a boat or an armored cash transport car) illustrated in  FIGS. 9( b ) and 9( c )  set to the security-deactivated status, a suspicious person has intruded into the warning area  24  without carrying the RFID tag  18 , and the detection means  14  have detected the suspicious person. 
     (S 215 ) The determination result notification unit  5  notifies the external terminal  17  of the result of the determination performed by the determination unit  10 . Further, the image information transmission unit  6  transmits, to the external terminal  17 , image information containing the still image or moving image obtained as a result of capturing the security status of the security area  23  and warning area  24  of the security target  22  by the imaging means  16 . The user or the security service provider who owns and uses the external terminal  17  can know the security status of the security target  22  and can take a corresponding measure. 
     (S 216 ) The warning instruction unit  7  instructs the warning means  15  to output a warning. The warning buzzer sounds a warning, and the light emitting device emits light, so as to provide notification of the abnormality. In addition, the position of the suspicious person in the warning area  24  is recognized through the above-described processing performed by the person detection position recognition unit  11 , and the detection frequency of the detection means  14  is increased through the processing performed by the detection condition setting unit  12 , so as to track the suspicious person. 
     [Security System] 
     A security system according to the present embodiment is a security system that controls a security status of a security target to a security-activated or security-deactivated status based on whether a person has been detected within a detection range of a detection means that detects a person and whether an RFID reception device has received identification information on an RFID or whether the RFID reception device has identified the RFID tag. 
     A security system  31  illustrated in  FIG. 13  includes a server device  32  installed by the security service provider, the security device  1 B illustrated in  FIG. 2 , a user terminal  33  such as a smartphone, a tablet terminal, a personal computer, or a mobile phone used by the user  29  related to the security target  22 , and a service provider terminal  34  such as a smartphone, a tablet terminal, a personal computer, or a mobile phone used by the security service provider. The same components as the components of the security device  1 B illustrated in  FIG. 2  are denoted by the same reference numerals, and no description will be given below of such components. 
     The security device  1 B, the user terminal  33 , and the service provider terminal  34  are communicatively connected to the server device  32  over a communication network  35  such as the Internet, a radio communication network adhering to a radio communication standard, or a wired communication network adhering to a wired communication standard. 
     As illustrated in  FIG. 13 , the server device  32  includes an information transmission/reception unit  36 , a control unit  37 , a storage unit  38 , an authentication unit  39 , a security status setting instruction unit  40 , a security status information creation unit  41 , an elapsed time measurement unit  42 , and an abnormality detection information creation unit  43 . 
     The information transmission/reception unit  36  transmits and receives information to and from the security device  1 B, the user terminal  33 , and the service provider terminal  34 . 
     The authentication unit  39  acquires, from the user terminal  33 , an authentication request for instructing the security device  1 B to set the security status of the security target  22  to the security-activated or security-deactivated status and performs authentication processing. This authentication processing is performed using a known authentication technology. 
     The security status setting instruction unit  40  performs processing of causing the user terminal  33  that has succeeded in authentication to make a selection for the security status of the security target  22 . A predetermined selection screen is displayed on the user terminal  33  to allow selection between the security-activated status and the security-deactivated status for the security status of the security target  22 . 
     The security status information creation unit  41  performs processing of creating security status information based on the security status of the security target  22  selected by the user terminal  33  or the security status of the security target  22  set by the security device  1 B. 
     For example, as shown in Table 1, when the security status setting instruction unit  40  performs processing of causing the user terminal  33  that has succeeded in authentication to make a selection for the security status of the security target  22 , and the user terminal  33  selects the security-deactivated status for the security status of the security target  22  set to the security-activated status, the security status information creation unit  41  creates security status information in which a flag “1” indicating that the security status of the security target  22  is a standby status for security deactivation is associated with selection instruction information (instruction for selection of the security-deactivated status) from the user terminal  33  and transmits the security status information to the security device  1 B. 
     In this case, the security target  22  is under security by the security device  1 B, but the security target  22  is in a standby status where the security-deactivated status can be set by identifying the RFID tag  18  held by the user  29 . 
     Further, when the security status control unit  13  of the security device  1 B sets the security status of the security target  22  to the security-deactivated status through the above-described determination processing 2 performed by the determination unit  10  of the security device  1 B ( FIG. 11 : S 206 ), the security status information creation unit  41  creates the security status information in which a flag “1” indicating that the security status of the security target  22  is switched from the security-activated status to the security-deactivated status is associated with setting processing information (setting of the security-deactivated status) of the security device  1 B and transmits the security status information to the security device  1 B.

     The storage unit  38  stores information on authentication such as an ID and a password of the user  29  necessary for the authentication unit  39  to authenticate the user terminal  33 , the security status information created by the security status information creation unit  41 , the result of the determination performed by the determination unit  10  transmitted from the security device  1 B, information on the security state of the security target  22  (image information obtained by the imaging means  16 ), and the like. 
     When the security status setting instruction unit  40  performs processing of causing the user terminal  33  that has succeeded in authentication to make a selection for the security status of the security target  22 , and the user terminal  33  selects the security-deactivated status for the security status of the security target  22  set to the security-activated status, the elapsed time measurement unit  42  measures a time elapsed from the selection and determines whether a predetermined time (for example, 10 minutes) has elapsed. This is to cancel the above-described standby status where the security status of the security target  22  can be set to the security-deactivated status. 
     When the elapsed time measurement unit  42  determines that the predetermined time has elapsed, that is, when the RFID  18  held by the user  29  has not been identified, the security status control unit  13  of the security device  1 B maintains the security status of the security target  22  in the security-activated status, and the security status information creation unit  41  creates security status information in which a flag “0” indicating that the standby status where the security status of the security target  22  can be set to the security-deactivated status has been canceled is associated with the setting processing information of the security device  1 B and transmits the security status information to the security device  1 B. 
     When the elapsed time measurement unit  42  determines that the predetermined time has not elapsed, that is, when the user  29  has come to the warning area  24  with the RFID tag  18 , the determination unit  10  of the security device  1 B determines the security status of the security target  22  in accordance with the above-described security processing pattern C. 
     As a result, when it is determined that there is no abnormality in entry processing, the security status control unit  13  of the security device  1 B sets the security status of the security target  22  to the security-deactivated status based on the security status information acquired from the server device  32 . 
     The abnormality detection information creation unit  43  performs processing of creating abnormality detection information for use in notification of an abnormality detected in the security target  22  based on the result of the determination performed by the determination unit  10  transmitted from the security device  1 B. The abnormality detection information thus created is transmitted to the user terminal  33  and the service provider terminal  34 . 
     The user  29  and the security service provider can immediately know the security status of the security target  22  based on the abnormality detection information thus transmitted and can take a corresponding measure. 
     The processing performed by each unit is controlled by the control unit  37  including a CPU, a RAM, a ROM, and the like. 
     As described above, according to the present embodiment, a building such as a house, an office (business office), a public facility, or an entertainment facility, a structure such as a shrine, a temple, or a greenhouse, or a movable property such as a vehicle including an automobile, a bicycle, and an armored cash transport car, or a ship including a yacht and a boat is defined as the security target, and the security system can be constructed in the security area and/or the warning area defined for the security target. This makes it possible to perform not only conventional detection of whether a suspicious person has intruded into a building, but also detection of whether the suspicious person has intruded into the warning area defined outside the building. 
     Further, the above-described determination processing on the security status of the security target facilitates the confirmation of whether a suspicious person has intruded from the warning area into the security area, and allows the security status of the security target to be automatically controlled to the security-activated status based on various detection patterns of the detection means, so that it is possible to prevent the activation of security from being forgotten and make security higher. 
     [Security Processing by Security System] 
     A description will be given below of a flow of security processing by the security system  31  illustrated in  FIG. 13  with reference to  FIGS. 14 and 15 . Note that the flow of the security processing by the security device  1 B included in the security system  31  corresponds to the above-described security processing patterns C, D, and thus no description will be given below of the flow. 
     1. Security Processing Pattern E 
     A ship such as a yacht or a boat is set as the security target  22 , the detection means  14 A,  14 B illustrated in  FIG. 4( a )  and the security device  1 B including RFID reception devices  19 A,  19 B are installed at an anchorage that is the warning area  24 , and the security status of the security target  22  is set to the security-activated status (see  FIG. 9 ). Further, the owner (user  29 ) of the ship such as a yacht or a boat carries the RFID tag  18 . The storage unit  8  of the security device  1 B stores information on the security-deactivation detection order of the detection means “first: the detection means  14 A”. 
     (S 301 ) The user terminal  33  executes an application program related to the security system  31  according to the present embodiment, and transmits the authentication request for instructing the security device  1 B to set the security status of the security target  22  to the security-activated or security-deactivated status to the server device  32 . 
     (S 302 ) The authentication unit  39  performs processing of authenticating the user terminal  33  based on information on authentication such as an ID and a password of the user  29  stored in the storage unit  38 . 
     (S 303 ) The security status setting instruction unit  40  performs processing of causing the user terminal  33  that has succeeded in authentication to make a selection for the security status of the security target  22 . The predetermined selection screen is displayed on the user terminal  33  to allow selection between the security-activated status and the security-deactivated status for the security status of the security target  22 . 
     (S 304  to S 307 ) The security target  22  is set to the security-activated status, so that the user terminal  33  selects the security-deactivated status for the security status of the security target  22  (S 304 , S 305 : Y). 
     The security status information creation unit  41  creates security status information in which a flag “1” indicating that the security status of the security target  22  is a standby status for security deactivation is associated with the selection instruction processing information (instruction for selection of the security-deactivated status) from the user terminal  33  and transmits the security status information to the security device  1 B (S 307 ). In this case, the security target  22  is under security by the security device  1 B, but the security target  22  is in a standby status where the security-deactivated status can be set by identifying the RFID tag  18  held by the user  29 . 
     (S 308 , S 309 ) When the user terminal  33  selects the security-deactivated status for the security status of the security target  22  set to the security-activated status, the elapsed time measurement unit  42  measures a time elapsed from the selection and determines whether the predetermined time (for example, 10 minutes) has elapsed. 
     (S 310 ) When the predetermined time has not elapsed, that is, when the owner of the ship (user  29 ) has come to the warning area  24  with the RFID tag  18  (S 309 : N), the determination unit  10  of the security device  1 B determines the security status of the security target  22  in accordance with the above-described security processing pattern C. 
     As a result, when it is determined that there is no abnormality in entry processing, the security status control unit  13  of the security device  1 B sets the security status of the security target  22  to the security-deactivated status based on the security status information acquired from the server device  32 . 
     Subsequently, the processing proceeds to the above-described security processing pattern D. 
     After the security is deactivated, the position of the user  29  in the security area  23  or the warning area  24  can be recognized through the above-described processing performed by the person detection position recognition unit  11 , and the movement path of the user  29  can be confirmed through the processing of increasing the detection frequency of the detection means  14  performed by the detection condition setting unit  12 . 
     Further, the determination result notification unit  5  notifies the external terminal  17  of the result of the determination performed by the determination unit  10  that there is no abnormality, and the image information transmission unit  6  transmits, to the external terminal  17 , the identification information on the RFID tag  18  with the identification information on the RFID tag  18  associated with the image information containing the still image or moving image obtained as a result of capturing the security status of the security area  23  and warning area  24  of the security target  22  by the imaging means  16 , so that the security service provider who owns and uses the external terminal  17  can know the security status of the security target  22  and can confirm the owner of the RFID tag  18 . 
     (S 311  to S 313 ) When the user terminal  33  selects the security-activated status for the security status of the security target  22  set to the security-deactivated status (S 304 , S 305 : N, S 306 : Y), the security status information creation unit  41  creates security status information in which a flag “0” indicating that the security status of the security target  22  is set to the security-activated status is associated with the selection instruction processing information of the user terminal  33 , and transmits the security status information to the security device  1 B (S 307 ). In this case, the security status control unit  13  of the security device  1 B sets the security status of the security target  22  to the security-activated status (S 308 : N, S 311 : Y, S 313 ). 
     Further, when the user terminal  33  selects the security-deactivated status for the security status of the security target  22  set to the security-activated status, and the elapsed time measurement unit  42  measures a time elapsed from the selection and determines that the predetermined time has elapsed (S 308 : Y, S 309 : Y), that is, when the owner (user  29 ) has not come to the warning area  24  with the RFID tag  18 , the security status control unit  13  of the security device  1 B maintains the security status of the security target  22  in the security-activated status (S 313 ). Further, the security status information creation unit  41  creates security status information in which a flag “0” indicating that the standby status where the security-deactivated status can be set to the security target  22  is associated with the setting processing information of the security device  1 B. 
     Subsequently, the processing proceeds to the security processing pattern E and the above-described security processing pattern D. 
     2. Security Processing Pattern F 
     (S 207 , S 214 ) When the determination unit  10  determines that the security status of the security target  22  shows an intrusion abnormality in the above-described security processing patterns C, D by the security device  1 B, the determination result notification unit  5  transmits the result of the determination to the server device  32  (S 208  and S 215  in  FIG. 11 ). 
     (S 401 ) The abnormality detection information creation unit  43  of the server device  32  performs processing of creating abnormality detection information for use in notification of an abnormality detected in the security target  22  based on the result of the determination or the image information by the imaging means  16  transmitted from the security device  1 B. The abnormality detection information thus created is transmitted to the user terminal  33  and the service provider terminal  34 . 
     (S 402 ) The owner (user  29 ) or the security service provider can immediately know the security status of the security target  22  based on the abnormality detection information thus transmitted and can quickly take a corresponding measure (for example, notify the police, dispatch security guards, or the like). 
     In addition, the position of the suspicious person in the security area  23  or the warning area  24  is recognized through the above-described processing performed by the person detection position recognition unit  11 , and the detection frequency of the detection means  14  is increased through the processing performed by the detection condition setting unit  12 , so as to track the suspicious person.
