【発明の詳細な説明】 産業上の利用分野 本発明は、監視用カメラを用いて侵入を検知する防犯
カメラ装置に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security camera device for detecting intrusion using a surveillance camera.
従来の技術 近年、監視カメラを用いて、デパート・マーケットの
売り場やビル内の金庫監視などの防犯を目的としたセキ
ュリティシステムが普及している。2. Description of the Related Art In recent years, security systems using surveillance cameras for the purpose of crime prevention, such as surveillance of department store market floors and safes in buildings, have become widespread.
従来の監視カメラはそのモニター映像を管理室に配置
されたテレビジョンモニターにてモニターすることで人
の侵入をたえず監視していた。The conventional surveillance camera constantly monitors the intrusion of people by monitoring the monitor image on a television monitor arranged in the control room.
発明が解決しようとする問題点 ところがこのようなシステムでは監視する人がたえず
画面に注目しておらねばならず画面から目を離すことが
できなかった。Problems to be Solved by the Invention However, in such a system, the person who watches must always pay attention to the screen and cannot keep an eye on the screen.

たことを示す報知信号を出すようにしたものである。Means for Solving the Problems The security camera device of the present invention includes a distance measuring circuit for image pickup focus adjustment of a television camera having an infrared ray or ultrasonic wave emitting portion and a light receiving portion, and detection for detecting intrusion. Comprising setting means for setting the range, the measured value measured by the distance measuring circuit is compared with the set value of the predetermined width set by the setting means, and the measured value falls within the range of the set value. In this case, a notification signal indicating that it has been detected is issued.

ている。Embodiment Hereinafter, a security camera device according to an embodiment of the present invention will be described with reference to the drawings. The drawing is an electrical block diagram of a security camera device according to an embodiment of the present invention, in which a video signal from the television camera 1 is displayed on a monitor 5.
In addition, the focus adjustment of the television camera 1 is performed by transmitting and receiving infrared rays or ultrasonic waves toward the subject from the distance measurement circuit 1c of the focus adjustment unit 1a to obtain the distance between the subject and the camera, and the automatic focus adjustment circuit 1d is used for focusing. The position of the subject is detected and the lens system is driven to focus the subject. Here, in order to intensively monitor the fixed range of the target monitored object, the set value is adjusted by the setting circuit 3 within the fixed range of the target monitored object, and the measured value from the distance measuring circuit 1c is compared with the comparison circuit 2. By doing so, the area around the target monitored object is constantly monitored, and if the measured value is within a certain range of the set target monitored object, an alarm signal is sent to notify the intrusion to the outside. It is sent out to No. 4 and is notified to the outside by voice notification, alarm buzzer notification, etc. according to the purpose of notification.
発明の効果 以上のように本発明の防犯カメラ装置は、カメラの撮
像範囲内の設定された位置に人または物の侵入が検知さ
れると報知信号を出し、外部の人に知らせるようにした
もので、人の目のみに頼った監視による見落しを防ぎ、
また画面を常時監視しなくても音などによる報知で知る
ことができるようになった。EFFECTS OF THE INVENTION As described above, the security camera device of the present invention outputs a notification signal when an intrusion of a person or an object is detected at a set position within the imaging range of the camera to notify an outside person. So, prevent oversight by monitoring relying only on human eyes,
In addition, it is now possible to know by sound alerts without constantly monitoring the screen.
