Description

[Detailed description of the invention] [Purpose of the invention] (Industrial use bone!'f) The present invention relates to a security tracking system.

(Conventional technology) Conventionally, crime prevention has been used in buildings and other facilities that require crime prevention.
J (If the security guard himself actually patrols each floor of the building and finds someone acting suspiciously, he will take charge of that person, and if that person runs away, ,
This is done by the security guards themselves tracking the person.

However, this method of having the security guard patrol the building himself is not only dangerous, but also increases the labor cost for the security guard, and it also means that when tracking a suspicious person, the person may not be able to be tracked and the person may escape. The reality is that this is not a desirable crime prevention method.

(Problem to be solved by the invention) As shown in I-L, conventional methods require security guards to patrol themselves, which not only poses problems in terms of safety and labor costs, but also makes it difficult to track down suspicious persons. There was also the problem that the person would be let go.

The purpose of the present invention is to improve safety and reduce personnel costs by monitoring suspicious person's actions in one place without requiring security guards to patrol themselves. To provide a crime prevention tracking system capable of outputting a warning without letting a person escape.

Structure of the Invention] (Means for Solving the Three Problems) In order to achieve the above object, the crime prevention tracking system according to the present invention is provided with a crime prevention tracking system installed at predetermined intervals along a passageway in an area where crime prevention is required. (Several monitor cameras, a display means for displaying images from the monitor cameras, a human power means having a suspicious button and an alarm button operated by an operator, and an output means for outputting an alarm,
a) A function that detects the movement direction of a suspicious person captured by a monitor camera when a suspicious button operation signal is given from human means; (b) A function that detects the movement direction of a suspicious person captured by a monitor camera; A function that determines whether or not the suspicious person is out of sight, and outputs an activation signal to a monitor camera installed in the direction of movement of the suspicious person if the suspicious person is out of the field of view, (c) Display processing to display the image of the monitor camera. (d) processing control means having a function of outputting an alarm processing signal for outputting an alarm to the output means when an alarm button operation signal is given from the input means to the display means; It consists of

(Function) In the crime prevention tracking system of the present invention, when the operator finds a person who seems suspicious while watching the image projected on the display means through the monitor camera and operates the suspicious button on the manual means, an operation signal to that effect is sent. is given to the processing control means. This allows the direction of movement of the suspicious person captured by the monitor camera to be detected. If a suspicious person moves out of the field of view of the monitor camera that captures the person, an activation signal is output to the monitor camera installed in the direction of the person's movement. The monitor cameras are switched and activated one after another according to the direction of movement of the person.

In this case, the monitor camera always captures the suspicious person's actions and displays the images one after another on the display means-1-.
If the operator sees this and determines that the person has committed a crime, an alarm will be output from the output means by operating the alarm button on the input means, so the operator will not miss the suspicious person's actions. This allows for safe tracking.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an example of the configuration of a crime prevention tracking system according to the present invention. As shown in FIG. 1, the security tracking system of this embodiment includes several stages (seven in this example) of monitor cameras 11 to 17, display means 2, input means 3, output means 4, and processing control. It consists of means 5.

Here, several stages of monitor cameras 11 to 17 are installed at predetermined intervals as shown in the figure along a passageway of a building or the like that requires security. On the other hand, the display means 2 consists of a CRT display or the like, and is for displaying images from the monitor cameras 11 to 17.

The human power means 3 also includes a suspicious button 31 operated by an operator. And what are you doing with the alarm button 32? Furthermore, the output means 4 is for outputting a warning.

On the other hand, the processing control means 5 has the following functions (a) to (d).

(a) A function of detecting the movement direction of a suspicious person captured by the monitor camera when operation No. 48 of the suspicious button 3 is given from the human power means 3.

(b) Determine whether the suspicious person leaves the field of view of the monitor camera capturing the person, and if the suspicious person leaves the field of view, send an activation signal to the monitor camera installed in the direction of movement of the suspicious person. Function to output.

(c) outputting a display signal to the display means 2 for displaying the images of the monitor cameras 11 to 17);

(d) A function of outputting an alarm processing signal to output an alarm to the output means 4 when the operation signal of the alarm button 32 is given from the input means 3.

Next, one operation of the crime prevention tracking system configured as described below will be explained using the flow diagram shown in FIG.

When the operator, for example, looks at the image projected on the display means 3 through the monitor camera 11 and tries to find someone who seems suspicious (Step Sl), operates the suspicious button 31 of the manual means 3 (Step S2), a message to that effect is displayed. The operation signal is given to the processing control means 5. As a result, the suspicious moving direction captured by the monitor camera 11 is detected (step S3). Then, it is determined in the first stage 5 of the processing control whether or not the sound of the suspicious person is out of the field of view of the monitor camera 11 (step S4).
If the person leaves the field of view, i'K will be displayed in the direction of the person's movement.
An activation signal is output to the monitor camera 12 that has been turned on (step S5). From here on, do the same in step 8.
By repeating the processes from 3 to S5, the monitor camera is switched one after another in the direction of movement of the suspicious person, such as 12.13.14.15 or 1.2.13°16.17. can be activated. Also in this case,
Each monitor camera always captures the behavior of a suspicious person and displays the images one after another on the display means 3, so when the operator tracks down a suspicious person to some extent by looking at this, that person is guilty of a crime. If it is determined that
An alarm is output from.

This allows the operator to safely track suspicious persons without overlooking their actions.

As described above, in the crime prevention tracking system of this embodiment, the behavior of a suspicious person who has entered the building can be monitored at one location by the display means 3 through the monitors 1 to 87, which is different from the conventional system. It is possible to monitor the behavior of suspicious persons without requiring patrols by security guards themselves, and it is possible to improve safety and reduce personnel costs. Furthermore, when tracking a suspicious person, it is possible to output a warning without causing the person to escape without being tracked. Therefore,
This provides an extremely practical and safe crime prevention tracking system.

〔Effect of the invention〕

As explained above, according to the present invention, the behavior of a suspicious person is monitored by switching between several monitor cameras and the display means, and when it is determined that the suspicious person is committing a crime, By operating the alarm button, the alarm is output from the output means, so the behavior of suspicious persons can be monitored from one place without the need for patrolling by the user himself, improving safety and reducing personnel costs. To provide a crime prevention tracking system capable of reducing costs and outputting an alarm when tracking a suspicious person without letting the person escape.
