Description

本発明は、マイクロ波を用いて侵入監視エリアなどへの不審者の侵入を検出して警報する監視システムに関する。 The present invention relates to a monitoring system that detects and alerts a suspicious person intrusion into an intrusion monitoring area using microwaves.

従来から侵入者を検出して警報、あるいは警備会社などに通報する侵入者検出システムが知られており、その侵入者を検知するセンサとしてマイクロ波を用いたドップラーセンサは、マイクロ波が金属以外の物質を透過可能であり、家屋内、家屋外といった設置場所の制限が少ないことから、各種の侵入者検出システムに採用されている。例えば、特許文献１に示すセキュリティ装置は、対象物の接近・離反を判定可能なマイクロ波ドップラーセンサを内蔵するセキュリティ装置を、窓側に向けて屋内の天井に取り付け、ドップラーセンサの監視方向（マイクロ波の出力信号の放射方向）が、窓ガラスに対して上部から所定の角度（伏角θ＝約４５°）になるように設定し、窓からの侵入者を検知するように構成している。 Conventionally, an intruder detection system that detects an intruder and notifies an alarm or a security company is known. A Doppler sensor using a microwave as a sensor for detecting the intruder is a microwave other than a metal. It is used in various intruder detection systems because it can permeate substances and has few restrictions on installation locations such as indoors and outdoors. For example, in the security device disclosed in Patent Document 1, a security device including a microwave Doppler sensor that can determine whether an object is approaching or moving away is attached to an indoor ceiling facing the window side, and the Doppler sensor monitoring direction (microwave (Radiation direction of the output signal) is set to a predetermined angle from the upper part (an obtuse angle θ = about 45 °) with respect to the window glass, and an intruder from the window is detected.

また、特許文献２には、監視エリアに対向して配置された送信装置及び受信装置並びに侵入判定を行う判定装置からなり、送信装置から受信装置に向けて送信したマイクロ波（送信波）の受信装置における受信信号に基づいて侵入者あるいは侵入物の監視エリアへの侵入の有無を判定するマイクロ波侵入検出装置が提案されている。 Patent Document 2 includes a transmission device and a reception device arranged opposite to a monitoring area, and a determination device that performs intrusion determination, and receives a microwave (transmission wave) transmitted from the transmission device to the reception device. There has been proposed a microwave intrusion detection apparatus that determines whether or not an intruder or an intruder has entered a monitoring area based on a received signal in the apparatus.

前記特許文献１、２で開示される侵入検出装置は、監視エリア内に侵入した侵入者や不審車両などが侵入した際、セキュリティ上、問題のない場合であっても、侵入検出信号を出力してしまう。このため、その都度、異常の有無をチェックする必要があり、侵入警報頻度が高くなってしまい、侵入警報に対する信頼性を低下させることも懸念される。このため、例えば、特許文献３などでは、侵入不審者や不審侵入車両（以下、単に障害物という）を検知する検知手段とカメラなどの撮像手段を組み合わせ、侵入検出信号が出力された際の映像を確認して異常の有無を確認する監視システムも知られている。 The intrusion detection devices disclosed in Patent Documents 1 and 2 output an intrusion detection signal even when there is no security problem when an intruder or a suspicious vehicle that has entered the surveillance area enters. End up. For this reason, it is necessary to check whether or not there is an abnormality each time, and the frequency of the intrusion alarm becomes high, and there is a concern that the reliability of the intrusion alarm is lowered. For this reason, for example, in Patent Document 3 and the like, an image when an intrusion detection signal is output by combining a detection means for detecting an intruder and a suspicious intrusion vehicle (hereinafter simply referred to as an obstacle) and an imaging means such as a camera. There is also known a monitoring system that confirms whether there is an abnormality.

このような、撮影手段と検知手段を組み合わせた監視システムとして、比較的、広い監視エリアの監視を行うシステムにおいて、障害物を検知した際、カメラによって撮影する際、その位置が特定されない場合、的確なアングル制御やフォーカス制御あるいはズーミング制御が行えないから、鮮明な映像が得られないため、監視エリアにおいて侵入者や不審車両を的確に検知することができない、という課題を有している。 In such a monitoring system combining a photographing means and a detecting means, in a system that monitors a relatively large monitoring area, when an obstacle is detected and the position is not specified when photographing with a camera, it is appropriate. Since angle control, focus control, and zooming control cannot be performed, clear images cannot be obtained, and there is a problem that intruders and suspicious vehicles cannot be accurately detected in the monitoring area.

本発明は上記の課題を解決するためになされたもので、監視領域内への侵入者や不審車両などの障害物の位置を正確に検知し、セキュリティ上問題がある場合に侵入検出信号を効果的に出力する監視システムを提供することを目的とする。 The present invention has been made in order to solve the above-mentioned problems, and accurately detects the position of an obstacle such as an intruder or a suspicious vehicle in the monitoring area, and the intrusion detection signal is effective when there is a security problem. It aims at providing the surveillance system which outputs automatically.

Is transmitted to the wireless unit of the first microwave transmitter / receiver, but in the line intrusion monitoring mode, the signal sent from the second microwave sensor is discarded, and in the line intrusion monitoring mode, the first When the intrusion of an obstacle into the monitoring area is detected by blocking between the microwave sensor and the reflector, the mode switches to the area intrusion monitoring mode, The determination means determines at which position the obstacle is located between the first microwave sensor and the reflector, and angle control and focus control of the surveillance camera as the imaging means according to this position information , Performing zooming control, transmitting accurate video / audio of the obstacle to the base station receiver and displaying it on the external monitor of the base station receiver, and recording video / audio from the monitoring camera and microphone It is characterized by being configured to record in

Of course, it goes without saying that the present invention can be easily applied to other than those described in the embodiments without departing from the spirit of the invention.

以下、本実施例における監視システムの構成について説明する。本実施例の監視システムは、監視エリアを監視して侵入者や不審侵入者車両などの障害物を検出して検知信号を出力する２台のマイクロ波送受信装置１、１０（以下、単に送受信装置という）と、撮影手段としての監視カメラ２０、警報手段としての警報ブザー３５，４３、録画装置３６などから構成され、テロ対策などに用いる対人用の侵入監視を想定している。 Hereinafter, the configuration of the monitoring system in the present embodiment will be described. The monitoring system of the present embodiment includes two microwave transmission / reception devices 1 and 10 (hereinafter simply referred to as transmission / reception devices) that monitor a monitoring area, detect obstacles such as intruders and suspicious intruder vehicles, and output detection signals. It is assumed that the surveillance camera 20 as an imaging means, the alarm buzzers 35 and 43 as alarm means, the recording device 36, etc., and intrusion monitoring for humans used for anti-terrorism measures and the like.

図１は本発明の監視システムＡの基本構成を表すブロック図を示したものであり、第１及び第２の送受信装置１、１０は監視エリアを挟むように対向して配置されている。第１の送受信装置１はマイクロ波により障害物を検知する第１のマイクロ波センサ２、無線ユニット３、送信ユニット４、判定手段たる制御ユニット５、マグネットスイッチ６、ＴＶ電話モジュール７、前記監視カメラ２０、マイク２１で構成され、これらの構成部品を防塵防水ボックス８内に収納しており、第２の送受信装置１０は、第２のマイクロ波センサ１２、無線ユニット１３、制御ユニット１４、マグネットスイッチ１５、反射板１６で構成され、これらの構成部品を防塵防水ボックス１７内に収納している。 FIG. 1 is a block diagram showing the basic configuration of the monitoring system A of the present invention. The first and second transmission / reception devices 1 and 10 are arranged to face each other with a monitoring area interposed therebetween. The first transmission / reception device 1 includes a first microwave sensor 2 that detects an obstacle using microwaves, a wireless unit 3, a transmission unit 4, a control unit 5 that is a determination unit, a magnet switch 6, a TV phone module 7, and the monitoring camera. 20 and a microphone 21, and these components are housed in a dustproof and waterproof box 8. The second transmitting / receiving device 10 includes a second microwave sensor 12, a wireless unit 13, a control unit 14, and a magnet switch. 15 and a reflector 16, and these components are housed in a dustproof and waterproof box 17.

また、前記第１及び第２のマイクロ波センサ２，１２は、マイクロ波を発信する発信部と、反射したマイクロ波を受信する受信部（何れも図示せず）をそれぞれ備えている。そして、第１のマイクロ波センサ２から送信されたマイクロ波は、第２の送受信装置１０内に設けた反射板１６で反射させ、その反射波を第１の送受信装置１の受信部で受信するとともに、第２のマイクロ波センサ１２からは、第１のマイクロ波センサ２の周波数と異なるマイクロ波が送信され、障害物で反射した反射波を第２のマイクロ波センサ１２の受信部で受信している。ここで、第１のマイクロ波センサ２と反射板１６とは予め設定された間隔を置いて配置され（例えば１００ｍを想定）、前記第１のマイクロ波センサ２から反射板１６までの距離を専用端末によって表示し、予め設定された距離（１００ｍ）に調整して第１のマイクロ波センサ２に登録する。また、第１のマイクロ波センサ２の指向性は、第１のマイクロ波センサ２に対して２°以上、反射板１６がずれると第１のマイクロ波センサ２が反射板１６からの反射波を検知しない設定とし、前記第２のマイクロ波センサ１２は、第２のマイクロ波センサ１２から送信するマイクロ波の周波数と反射波の周波数との差分により、障害物を検知する。 Each of the first and second microwave sensors 2 and 12 includes a transmitter that transmits microwaves and a receiver (not shown) that receives the reflected microwaves. The microwave transmitted from the first microwave sensor 2 is reflected by the reflecting plate 16 provided in the second transmitting / receiving device 10, and the reflected wave is received by the receiving unit of the first transmitting / receiving device 1. At the same time, a microwave different from the frequency of the first microwave sensor 2 is transmitted from the second microwave sensor 12, and the reflected wave reflected by the obstacle is received by the receiving unit of the second microwave sensor 12. ing. Here, the first microwave sensor 2 and the reflection plate 16 are arranged at a predetermined interval (for example, 100 m is assumed), and the distance from the first microwave sensor 2 to the reflection plate 16 is dedicated. Displayed by the terminal, adjusted to a preset distance (100 m), and registered in the first microwave sensor 2. The directivity of the first microwave sensor 2 is 2 ° or more with respect to the first microwave sensor 2, and the first microwave sensor 2 transmits the reflected wave from the reflector 16 when the reflector 16 is displaced. The second microwave sensor 12 detects an obstacle based on the difference between the frequency of the microwave transmitted from the second microwave sensor 12 and the frequency of the reflected wave.

前記送受信装置１の送信ユニット４から送信される信号は中継局５０を中継して前記基地局用受信機３０の受信ユニット３１に出力される。この基地局用受信機３０は前記送受信装置１、１０から離れた警備会社や警備用基地、あるいは警備機関内に設置され、図２に示すように、前記送信ユニット４から送信される信号を受信する受信ユニット３１、前記監視カメラ２０及びマイク２１から送られる映像・音声信号を復調して出力する映像・音声出力装置３４、この映像・音声出力装置３４からの信号によって監視カメラ２０及びマイク２１から送られる映像あるいは静止画を表示する外部モニター３３、警報手段として警報ブザー３５、監視カメラ２０、マイク２１から送られる映像と音声を記憶する録画装置３６を備えている。 A signal transmitted from the transmission unit 4 of the transceiver 1 is relayed through the relay station 50 and output to the reception unit 31 of the base station receiver 30. The base station receiver 30 is installed in a security company, a security base, or a security agency away from the transmission / reception devices 1 and 10, and receives a signal transmitted from the transmission unit 4 as shown in FIG. The video / audio output device 34 that demodulates and outputs the video / audio signal sent from the receiving unit 31, the monitoring camera 20 and the microphone 21, and the monitoring camera 20 and the microphone 21 according to the signal from the video / audio output device 34. An external monitor 33 for displaying a video or still image to be sent, an alarm buzzer 35 as alarm means, a monitoring camera 20, and a recording device 36 for storing video and audio sent from the microphone 21 are provided.

また、前記送受信装置１の送信ユニット４から送信される信号は、監視エリアの警備担当者が携帯する携帯型受信機４０（例えばＴＶ機能付き携帯電話）にも出力される。この携帯型受信機４０は図２に示すように、前記送信ユニット４から送信される信号を受信する受信ユニット４１、モニター４２、映像・音声出力装置４３、警報手段として警報ブザー４４、ＣＨ切替スイッチ４５で構成されている。 The signal transmitted from the transmission unit 4 of the transmission / reception device 1 is also output to a portable receiver 40 (for example, a mobile phone with a TV function) carried by a security officer in the monitoring area. As shown in FIG. 2, the portable receiver 40 includes a receiving unit 41 that receives a signal transmitted from the transmitting unit 4, a monitor 42, a video / audio output device 43, an alarm buzzer 44 as an alarm means, and a CH switch. 45.

なお、前記送受信装置１、１０に備えた前記マグネットスイッチ６，１５は、各防塵防水ボックス８，１７の開閉扉（図示せず）を検知し、開閉扉が開いていると、第１及び第２のマイクロ波センサ２，１２の電源をオフするとともに、マグネットスイッチ６，１５の信号を送信ユニット４から基地局用受信機３０及び携帯型受信機４０に送信し、基地局用受信機３０を設置する例えば警備会社にて開閉扉が開いている旨の表示を行う。 The magnet switches 6 and 15 provided in the transmission / reception devices 1 and 10 detect the opening / closing doors (not shown) of the respective dustproof and waterproof boxes 8 and 17, and when the opening / closing doors are open, 2, the power of the microwave sensors 2, 12 is turned off, and the signals of the magnet switches 6, 15 are transmitted from the transmission unit 4 to the base station receiver 30 and the portable receiver 40. For example, the security door displays that the door is open at a security company.

以上のように構成される本実施例の作用について説明する。第１の送受信装置１の制御ユニット５は、第１のマイクロ波センサ２から送信される信号を常に監視するライン侵入監視モードで動作する。このライン侵入監視モードでは、反射板１６からの反射波を受信し、第１のマイクロ波センサ２と反射板１６との間隔に応じた第１のマイクロ波センサ２の信号のレベル変化を制御ユニット５で監視し、監視エリアに障害物（何らかの物あるいは人）が侵入し、第１のマイクロ波センサ２と反射板１６との間が遮られると、制御ユニット５は第１のマイクロ波センサ２の検出信号に基づいて障害物の存在を判定する。 The operation of this embodiment configured as described above will be described. The control unit 5 of the first transmission / reception device 1 operates in a line intrusion monitoring mode in which a signal transmitted from the first microwave sensor 2 is constantly monitored. In this line intrusion monitoring mode, the reflected wave from the reflecting plate 16 is received, and the level change of the signal of the first microwave sensor 2 according to the interval between the first microwave sensor 2 and the reflecting plate 16 is controlled. 5, when an obstacle (something or a person) enters the monitoring area and the space between the first microwave sensor 2 and the reflection plate 16 is blocked, the control unit 5 controls the first microwave sensor 2. The presence of an obstacle is determined based on the detected signal.

また、第２のマイクロ波センサ１２からの信号は、常に、無線中継ユニット１３から第１の送受信装置１の無線ユニット３に送信されるが、ライン侵入監視モードでは、第２のマイクロ波センサ１２から送られる信号は読み捨てられ、第１のマイクロ波センサ２の信号及び監視カメラ２０及びマイク２１の映像及び音声信号のみが、第１の送受信装置１の送信ユニット４とＴＶ電話モジュール７から中継局５０を経由して基地局用受信機３０と携帯型受信機４０に送信される。この監視カメラ２０及びマイク２１の映像及び音声信号が基地局用受信機３０、携帯型受信機４０の映像・音声出力装置３４，４２で復調され、基地局用受信機３０の外部モニター３３と携帯型受信機４０のモニター４２に表示されるが、ライン侵入監視モードでは、監視エリアの映像・音声は録画装置３６には記憶しない処理を行う。なお、携帯型受信機４０ではＣＨ切替スイッチ４２によって、他の画像又は映像に切り替えることができる。また、第１のマイクロ波センサ２からの信号によって障害物を検知していない信号であれば、ライン侵入監視モード（通常状態）である表示を例えばＬＥＤなどによって行う。 Further, the signal from the second microwave sensor 12 is always transmitted from the wireless relay unit 13 to the wireless unit 3 of the first transmission / reception device 1, but in the line intrusion monitoring mode, the second microwave sensor 12 is transmitted. The signal sent from the first radio wave sensor 2 is discarded, and only the signal of the first microwave sensor 2 and the video and audio signals of the monitoring camera 20 and the microphone 21 are relayed from the transmission unit 4 and the TV telephone module 7 of the first transmission / reception device 1. 50 to the base station receiver 30 and the portable receiver 40. The video and audio signals of the monitoring camera 20 and the microphone 21 are demodulated by the video / audio output devices 34 and 42 of the base station receiver 30 and the portable receiver 40, and are carried with the external monitor 33 of the base station receiver 30. In the line intrusion monitoring mode, the video / audio in the monitoring area is processed so as not to be stored in the recording device 36. Note that the portable receiver 40 can be switched to another image or video by the CH switch 42. In addition, if the signal from the first microwave sensor 2 does not detect an obstacle, the line intrusion monitoring mode (normal state) is displayed by, for example, an LED.

一方、ライン侵入監視モードにおいて、監視エリアに障害物（何らかの物あるいは人）が侵入し、第１のマイクロ波センサ２と反射板１６との間が遮られると、エリア侵入監視モードへと切り換わり、基地局用受信機３０、携帯型受信機４０にエリア侵入監視モードである警報信号が出力され、基地局用受信機３０、携帯型受信機４０の警報ブザー３５，４３が作動する。また、予め記憶された第１のマイクロ波センサ２と反射板１６との間（１００ｍ）における第１のマイクロ波センサ２のレベルデータと比較照合するとともに、第２のマイクロ波センサ１２からの検知信号によって、障害物が第１のマイクロ波センサ２と反射板１６と間のどの位置に存在するのかを判定し、この位置情報に従って監視カメラ２０のアングル制御、フォーカス制御、ズーミング制御を行い、障害物の正確な映像・音声を基地局用受信機３０に送信して基地局用受信機３０の外部モニター３３に表示するとともに、監視カメラ２０、マイク２１からの映像・音声を録画装置３６に録画するとともに、携帯型受信機４０にも表示させる。 On the other hand, in the line intrusion monitoring mode, when an obstacle (something or person) enters the monitoring area and the first microwave sensor 2 and the reflection plate 16 are blocked, the mode is switched to the area intrusion monitoring mode. Then, an alarm signal in the area intrusion monitoring mode is output to the base station receiver 30 and the portable receiver 40, and the alarm buzzers 35 and 43 of the base station receiver 30 and the portable receiver 40 are activated. In addition, the level data of the first microwave sensor 2 between the first microwave sensor 2 and the reflector 16 (100 m) stored in advance is compared and collated, and the detection from the second microwave sensor 12 is performed. The position of the obstacle between the first microwave sensor 2 and the reflection plate 16 is determined by the signal, and the angle control, focus control, and zooming control of the monitoring camera 20 are performed according to this position information. Accurate video / audio of the object is transmitted to the base station receiver 30 and displayed on the external monitor 33 of the base station receiver 30, and the video / audio from the monitoring camera 20 and microphone 21 is recorded on the recording device 36. At the same time, it is displayed on the portable receiver 40.

なお、エリア侵入監視モードでは、障害物の検知信号が出力されると所定時間、例えば１０秒間、エリア侵入監視モードを継続する。すなわち、第１のマイクロ波センサ２と反射板１６との間に障害物が検知され、その直後に反射板１６からの反射波を検知（第１のマイクロ波センサ２と反射板１６との間に障害物が存在しない）したとしても、１０秒間はエリア侵入監視モードを継続して警報ブザー３５，４４は警報音を鳴動し続けるとともに、録画装置３６に最低、１０秒の映像を録画する。また、１０秒以上、第１のマイクロ波センサ２，１２から検知信号が出力されると、警報状態を継続するが、１０秒以上経過後、第１のマイクロ波センサ２，１２から検知信号が無い場合、ライン侵入監視モードに戻り、警報ブザー３５，４３及び録画装置３６は停止する。 In the area intrusion monitoring mode, when an obstacle detection signal is output, the area intrusion monitoring mode is continued for a predetermined time, for example, 10 seconds. That is, an obstacle is detected between the first microwave sensor 2 and the reflecting plate 16, and immediately after that, a reflected wave from the reflecting plate 16 is detected (between the first microwave sensor 2 and the reflecting plate 16). Even if there are no obstacles), the area intrusion monitoring mode is continued for 10 seconds, the alarm buzzers 35 and 44 continue to sound an alarm sound, and a video of at least 10 seconds is recorded on the recording device 36. When a detection signal is output from the first microwave sensors 2 and 12 for 10 seconds or longer, the alarm state is continued, but after 10 seconds or longer, the detection signal is output from the first microwave sensors 2 and 12. If not, the line intrusion monitoring mode is restored, and the alarm buzzers 35 and 43 and the recording device 36 are stopped.

また、エリア侵入監視モード時において、マグネットスイッチ６，１５によって防塵防水ボックス８，１７の双方あるいはその何れか一方の開閉扉が開いた判定された場合、ライン侵入監視モードへと切り換わることなく、異常警報信号を出力し、開閉扉が開いていることを示すＬＥＤが点灯させるとともに、異常発生の警報音とは異なる警報音を鳴動させ、開閉扉が開いている旨の警報表示を行う。 Further, in the area intrusion monitoring mode, if it is determined that the dust switches and / or waterproof boxes 8 and 17 are opened by the magnet switches 6 and 15, the switching to the line intrusion monitoring mode is not performed. An abnormality alarm signal is output, and an LED indicating that the opening / closing door is open is turned on, and an alarm sound different from the alarm sound indicating the occurrence of an abnormality is sounded to indicate that the opening / closing door is open.

以上のように、本実施例においては、第１のマイクロ波センサ２と反射板１６との間に障害物が検知されると、ライン侵入監視モードからエリア侵入監視モードに切り換わり、基地局用受信機３０の警報ブザー３５による警報音と、ＬＥＤなどによる警報表示が成され、監視エリアでの異常を瞬時に知らせることができるとともに、予め記憶された第１のマイクロ波センサ２と反射板１６との間隔（１００ｍ）における第１のマイクロ波センサ２のレベルデータと、検知時のレベルデータとを比較照合して障害物の位置を特定し、その位置情報に従って監視カメラ２０のアングル制御、フォーカス制御、ズーミング制御を行うことにより、障害物の正確な映像・音声が基地局用受信機３０に送信することができる。これにより、その映像を確認することによって、不審者や不審車両の特定も容易であるとともに、セキュリティ上、問題ない例えば、動物や飛来物などが第１のマイクロ波センサ２と反射板１６との間に障害物として検知されたのかを容易に判別することができ、誤認による監視エリアへの出動といった無駄もなく、侵入警報に対する信頼性を高めることができる。また、基地局用受信機３０と同時に警備担当者などが携帯する携帯型受信機４０の警報ブザー４４からも警報音が、モニター４２で監視エリアの映像が出力され、監視エリアの確認がより簡単であるとともに、機動性の向上にも優れる。また、第１のマイクロ波センサ２と反射板１６との間に障害物が検知されると、１０秒間はエリア侵入監視モードを継続し、その間、警報音を鳴らし続けることにより、監視エリアの異常を見逃すことがないとともに、最低、１０秒間は監視エリアの映像・音声を録画装置３６に記憶することにより、不審者や不審車両の特定も容易である。 As described above, in this embodiment, when an obstacle is detected between the first microwave sensor 2 and the reflector 16, the line intrusion monitoring mode is switched to the area intrusion monitoring mode, and the base station An alarm sound by the alarm buzzer 35 of the receiver 30 and an alarm display by an LED or the like are made, so that an abnormality in the monitoring area can be notified instantaneously, and the first microwave sensor 2 and the reflector 16 stored in advance are stored. The level data of the first microwave sensor 2 and the level data at the time of detection are compared and collated with each other at an interval (100 m) to identify the position of the obstacle, and the angle control and focus of the monitoring camera 20 are determined according to the position information. By performing control and zooming control, an accurate video / audio of the obstacle can be transmitted to the base station receiver 30. This makes it easy to identify the suspicious person and the suspicious vehicle by confirming the image, and there is no problem in terms of security. For example, an animal or a flying object can be detected between the first microwave sensor 2 and the reflector 16. Whether it is detected as an obstacle in the meantime can be easily determined, and there is no waste such as dispatch to the monitoring area due to misidentification, and the reliability of the intrusion alarm can be improved. Also, the alarm sound is output from the alarm buzzer 44 of the portable receiver 40 carried by the security officer at the same time as the base station receiver 30, and the monitor area video is output on the monitor 42, making it easier to check the monitor area. In addition, it has excellent mobility. Further, when an obstacle is detected between the first microwave sensor 2 and the reflecting plate 16, the area intrusion monitoring mode is continued for 10 seconds, and during that time, an alarm sound is continuously generated, thereby causing an abnormality in the monitoring area. In addition, it is easy to identify a suspicious person or a suspicious vehicle by storing the video / audio of the monitoring area in the recording device 36 for at least 10 seconds.

以上、本発明の実施例について詳述したが、本発明は、前記実施例に限定されるものではなく、本発明の要旨の範囲内で種々の変形実施例は可能である。例えば、前記実施例では監視カメラ２０を１台とした例を示したが、監視カメラの台数は限定されるものではい。また、エリア侵入監視モードに切り換わると、１０秒間、監視エリアの映像・音声を録画装置３６に記憶するように構成したが、記憶時間などは適宜選定すればよい。また、ライン侵入監視モードでの映像・音声を再生する方法として例えば、一定間隔毎に静止画を撮影して再生し、エリア侵入監視モードで連続した映像を記憶するように構成してもよい。さらに、前記実施例では、ライン侵入監視モードにおいて監視カメラ２０の映像を記憶せず、エリア侵入監視モード時に録画装置３６に映像を記憶させた例を示したが、監視カメラ２０の映像を常時、記憶し、その映像を所定期間、記憶させた状態とし、所定期間経過後、古い映像情報を新たな映像情報として録画するように構成してもよい。この場合、異常を知らせるエリア侵入監視モード時に撮影した映像と音声は、エリア侵入監視モードが発生した時間で記憶された映像を呼び出す処理を行えばよい。また、送受信装置１，１０の台数も一対の送受信装置１，１０を対向して配置する以外、例えば４台又はそれ以上の送受信装置をそれぞれ対向させて配置すればより広い監視エリアをカバーすることができる。 As mentioned above, although the Example of this invention was explained in full detail, this invention is not limited to the said Example, A various deformation | transformation Example is possible within the range of the summary of this invention. For example, in the above-described embodiment, an example in which the monitoring camera 20 is one is shown, but the number of monitoring cameras is not limited. In addition, when switching to the area intrusion monitoring mode, the video / audio of the monitoring area is stored in the recording device 36 for 10 seconds. However, the storage time and the like may be appropriately selected. Further, as a method for reproducing video / audio in the line intrusion monitoring mode, for example, a still image may be captured and reproduced at regular intervals, and a continuous video may be stored in the area intrusion monitoring mode. Furthermore, in the said Example, the video of the monitoring camera 20 was not memorize | stored in the line intrusion monitoring mode, but the video was memorize | stored in the recording device 36 at the area intrusion monitoring mode, but the video of the monitoring camera 20 was always shown. The video may be stored, the video is stored for a predetermined period, and the old video information is recorded as new video information after the predetermined period has elapsed. In this case, for the video and audio captured during the area intrusion monitoring mode to notify the abnormality, a process for calling up the stored video at the time when the area intrusion monitoring mode occurs may be performed. In addition, the number of the transmission / reception devices 1 and 10 can cover a wider monitoring area if, for example, four or more transmission / reception devices are arranged to face each other, except that the pair of transmission / reception devices 1 and 10 are arranged to face each other.
