The purpose is to provide a video surveillance system.

Still another object of the present invention is not only to easily deal with the situation caused by the change in the image caused by a lot of motion in the image taken by the motion detection function unit and the alarm unit, but also by the carelessness of the night worker It provides a camp video surveillance system that can prevent inadvertent accidents.

Another object of the present invention, since the user can set the sensitivity of the motion detection, it is possible to set the time zones with a lot of motion and the time zones with little movement to provide a camp video surveillance system capable of efficient monitoring. .

The camp video surveillance system of the present invention for achieving the above object is installed on the ceiling of the corridor to monitor the interior of the camp divided into a corridor and the camp by the iron bars in the central situation room, two CCD camera consisting of a board and a lens Wherein, the width of the board formed in the CCD camera is formed to the width that the lens can be formed, and arranged at an angle that the angle of view of the two CCD camera can be parallel, the angle of view of the two CCD camera It can be transmitted to the central situation room as a single image by combining a lens formed with an angle of view that can pass between the bars and bars in parallel while maintaining the same separation distance as the thickness, and the images taken by the power supply and two CCD cameras. A plurality of photographing units including an image combiner, and receiving and recording images and images captured by the plurality of photographing units In the camp video surveillance system of control and to control expression, parts of the image that can be expressed to express transfer image received from the controller,
The control unit of the central situation room detects a change in the sensitivity of the image taken by the user in order to determine whether there is an abnormality in the camp by detecting a change in the movement of the image photographed by a plurality of photographing units. The motion detection function section is composed of a set key and a power key for turning a function on and off.

Hereinafter, the configuration of the present invention with reference to the accompanying drawings in more detail.

First, as shown in FIG. 4, the image capture unit 10 disposed on the ceiling of the corridor 2 and the image captured by the image capture unit 10 are photographed in the central situation room as shown in FIG. 4. Received from (3) consists of a control unit 30 for controlling to display to the recording and image display unit 40.

As shown in FIGS. 5 to 6, the photographing unit 10 includes two CCD cameras 11 and 21 and a power supply unit 13 including lenses 11a and 21a and boards 11b and 21b. .

Here, the two CCD cameras 11 and 21 are arranged so that the angles of view a of the lenses 11a and 21a constituting the respective CCD cameras 11 and 21 are arranged at an angle in parallel. In particular, a board configured in each of the CCD cameras 11 and 21 such that the separation distance d when the angle of view a is parallel may be equal to the thickness t of the prison bar 1. The lens 11a constituting the CCD cameras 11 and 21, with the width w of the 11b and 21b being formed to the minimum width w where each of the lenses 11a and 21a can be placed. , 21a) is configured to achieve a parallel state.

In addition, the photographing unit 10 further includes an image combiner 12 capable of combining the images photographed by the respective CCD cameras 11 and 21 into one to be transmitted to the central situation room 3.

On the other hand, the control unit 30 installed in the central situation room 3, as shown in Figure 7, the image recording unit for receiving the image recorded by the photographing unit 10 to record the image (not shown) And an image display unit 40 capable of checking the image captured by the photographing unit 10 in the central situation room 3 at the same time as the recording process of the image recording unit.

Here, the controller 30 may detect a change in the image as a change in the pixel so as to detect a change in the movement of the image transmitted from the photographing unit 10 and determine whether there is an abnormality in the camp 1. The motion detection function unit 31 may be further provided.

The motion detection function unit 31 arbitrarily selects a pixel change amount of the image received by the user in consideration of the fact that the movement of the prisoner's activity time and the sleeping time zone are different from each other when the motion inside the camp 1 is detected. It is provided with an adjustable sensitivity setting key 31a, and a power key 31b key for turning on / off the function of the motion detection function unit 31 so that the user is accommodated in the accommodation chamber 1. It is configured to stop the function when there is no phosphorus.

Here, when there are a plurality of storage chambers 1, the motion detection function unit 31 may detect each motion chamber using the motion detection function unit 31 for each of the storage chambers 1. Obviously, only one of the storage chambers 1) can be monitored using the motion detection function unit 31.

In addition, the control unit 40 interlocks with the motion detection function unit 31 at a time point when 1/2 of the detection setting value becomes 1/2 according to the value set by the detection degree setting key 31a of the motion detection function unit 31. It may further include an alarm unit 32 for issuing a preliminary alarm so as to, and when the detection set value is reached, an alarm sound can be activated to operate in conjunction with the motion detection function unit 31.

Here, the preliminary alarm and the alarm sound of the alarm unit 32 may be distinguished by various methods, and in particular, may be distinguished by using different sounds or may be distinguished by using continuous sound and interval repetitive sound. have.

A preferred embodiment of the camp video surveillance system of the present invention having the above configuration will be described in detail with reference to the accompanying drawings.

First, the photographing unit 10 for photographing the camp 1 is installed in the corridor 2, but the position where the photographing unit 10 is to be installed is maintained while maintaining a constant distance from the iron bar b. Then, based on the position where the photographing unit 10 is to be installed, the CCD cameras 11 and 21 are coupled to each other, and the lenses 11a and 21a of the CCD cameras 11 and 21 are configured. The distance d between the lens 11a and the lens 21a is equal to the thickness of the bar t in the state in which the angle of view a is parallel to each other, and the lenses 11a and 21a are disposed. The angle of view (a) is to arrange the lens (11a, 21a) forming an angle of view (a) that can pass between the bar (b) and the bar (b).

In addition, the controller 30 and the image display unit 40 are configured to receive the image photographed by the photographing unit 10 installed as described above in the central situation room 3 and display the recorded image.

Looking at the situation of monitoring by using the camp video monitoring system 50 of the present invention, the installation is completed as described above, as shown in Figure 8 by the photographing unit 10 of the present invention installed on the ceiling of the corridor (2) 1) If you take a picture inside, you can take a picture without interruption of the video without blind spots caused by iron bars.

Here, the distance (d) between the lens (11a, 21a) is spaced apart by the thickness (t) of the iron bars, but as the distance between the photographing unit 10 and the subject in the concentration camp (1) increases the contrast of the entire image Since the ratio of the blind spots decreases rapidly, as shown in FIG. 8 (b), when checking the image through the image display unit 40 in the central situation room 3, the image display unit is displayed as one line. Surveillance can be made easily without disturbing the monitoring of the inside of the camp (1) using the (40).

In addition, when the receiver approaches or closes the iron bar to prevent the photographing of the photographing unit 10, or closes the photographing unit 10 with a hand, a blanket, a towel, or the like, the control unit 30 of the central situation room 3 The motion of the object is increased proportionally on the entire screen by the motion detection function unit 31 installed in the alarm, and an alarm is issued by the alarm unit 32 operating in conjunction with the motion detection function unit 31. do.

Since the motion is stored in pixel units by the motion detection function unit 31 in which the sensitivity setting value is set by the user setting, a preliminary alarm is issued when the movement is small, and an alarm alarm when the moving object is large. Can be issued, and unintentional accidents caused by the carelessness of the watcher can be prevented.

In addition, when the sensitivity setting key 31a for adjusting the detection setting value of the motion detection function unit 31 is used, the user can arbitrarily adjust the setting of the time zone in which the prisoner is active and the time zone in which the prisoner is sleeping. Therefore, when the movement is excessive, such as when the prisoner is active, by increasing the detection setting value, it is possible to prevent the alarm unit 32 from being issued more than necessary, and the movement of the prisoner is like the time when the prisoner is sleeping. In rare cases, the detection setting can be lowered to detect the movement of the recipient sensitively.

As described above, the camp video surveillance system of the present invention has a structure in which a photographing unit consisting of two CCD cameras does not have a blind area caused by iron bars, so that the prisoner in the camp can be accurately monitored in the central situation room. have.

In addition, the motion detection function and the alarm unit can not only quickly deal with the situation caused by the video change caused by a lot of motion in the image captured by the shooting unit, but also inadvertent accidents that may occur due to the carelessness of night workers. Can be prevented in advance.

In addition, since the user can set the degree of detection of motion detection, it is a useful invention that can be set by distinguishing the time zone with a lot of motion and the time zone with little movement, thereby enabling efficient monitoring.
