The present invention relates to an intelligent video security system and a security method thereof, and more particularly, to an intelligent video security system and a security method including a rotatable camera unit that can be freely rotated in addition to at least one detection fixed camera unit.

As modern society becomes more complex, society faces various social problems such as social crime and disasters. In particular, in recent years, as crimes have rapidly increased from women's social problems such as sexual harassment and sexual violence to serial killings, each municipality is trying to reduce the slightest by installing CCTV.

In general, CCTV (Closed Circuit Television) camera system is one of the systems for monitoring or preventing security, security, parking, speeding, etc. installed in downtown alleys, parks and roadsides. However, by monitoring and cracking down on a single direction due to the characteristics of the system, it was impossible to monitor even if illegal activities occurred in the other direction.

Therefore, in order to simultaneously monitor multiple directions with a conventional CCTV camera system, it is necessary to install a plurality of cameras in a corresponding direction, thereby increasing the installation cost.

Referring to Figure 1, the support (10) fixed to the ground, and the arm 20 that can move in the vertical direction along the support (10) is connected, the arm 20 can be rotated to shoot the detection object The camera 30 is located. In the related art, one camera had to be prevented or intermittent, so the arm that could slide on the shore had to be rotated, and the camera 30 was rotated. However, since multiple cameras are installed to detect and photograph multiple directions at the same time, there is a problem in that installation costs and management costs increase.

2 is a view showing another security surveillance camera system according to the prior art.

In FIG. 2, the fixed type surveillance camera which can locate several cameras symmetrically and detect several directions simultaneously is shown. However, the conventional fixed surveillance cameras are limited in resolution due to low pixels, and thus, it is difficult to distinguish the form when the recorded screen is enlarged, and thus the identification power is reduced. In addition, there has been a problem that a blind spot occurs when installing a limited camera. Therefore, even if a plurality of cameras are installed and multiple directions are detected at the same time, the area immediately below the surveillance cameras cannot be photographed, causing a blind spot to occur.

In addition, pedestrians are always exposed to dangers because there is no distinction between sidewalks and driveways, and the green parking system (green parking village) is introduced due to the increased risk of local residents due to illegally parked vehicles. Residents are demanding definite measures for security that can be broken down. Not only are they demanding continuous parking control due to traffic inconvenience, they are also demanding crackdown on activities that harm the urban environment due to illegal garbage dumping. There is a situation.

And a cover 111 for protecting the fixed camera units 120a, 120b, 120c, and 120d, the rotating camera unit 130, and other electric circuits from the external environment. Since the intelligent image protection system is installed outside, it is made of a material resistant to external shock without corrosion, and the housing 130 and the cover 111 are preferably completely waterproof.

In addition, the support 112 may be connected to the upper portion of the housing so as to couple the housing 130 to which the cover 111 is coupled, such as alleys, road posts or walls. Therefore, one end of the support 112 is connected to the upper portion of the housing 110, and the other end is fixed to the wall or strut through the fastening means. On the other hand, the coupling portion 114 is located in the opening of the housing inward, the fixed camera portion (120a, 120b, 120c, 120d) and the hub 140 is coupled to the coupling portion 114 by the fixing plate. The cover is also coupled to the coupling portion. The hub 140 collects the images captured by the plurality of fixed camera units 120a, 120b, 120c, and 120d and the rotating camera unit 130, and transmits them to one, and may be installed in consideration of the amount of images. Can be.

The fixed camera units 120a, 120b, 120c, and 120d for detection detect and track a vehicle or a person in a surveillance area set in a road, an alley or a back road in real time, and be installed in plural to acquire images of various directions at the same time. Can be. At least one may be installed according to the position, and the fixed camera units 120a, 120b, 120c, and 120d may be coupled to the coupling part 114 of the housing through the tilting means 122 to minimize blind spots in the captured image.

That is, the fixed camera units 120a, 120b, 120c, and 120d may rotate in the vertical direction, and may be arbitrarily rotated and fixed according to the height and the position at which the video security system 100 is installed, or the motor may have a microcomputer 150. You can also remotely adjust the angle by connecting to the power supply and adjusting its power supply.

3 and 4, as a structure capable of monitoring four directions, it is possible to independently set the installation direction and angle of view of each of the cameras for the four directions in order to monitor non-uniform directions and distances. At this time, when the camera image is transmitted to the central center, it may cause trouble such as a communication line, and transmits it as a high-definition video (Full HD and D1) with a resolution of 1600 * 1200 or more and stores it in the memory 152, and monitors it as a high-definition video even in the central center. do. In addition, it is preferable that both optical 10 magnification and digital 12 magnification are supported so that shooting can be performed at a long distance.

Rotating camera unit 130 is fixed to the inside of the housing with a plurality of fixed camera unit (120a, 120b, 120c, 120d), should be able to rotate 360 degrees freely at the request of the microcomputer 150, wide angle A PTZ (Pan Tilt Zoom) camera that is adjustable from to narrow angle is preferable. In FIG. 4, the rotation camera unit 130 is positioned between the four fixed camera units 120a, 120b, 120c, and 120d, that is, the center of the housing, and is connected to the motor so as to be rotatable. The rotating camera unit 130 is based on the motion detection system input to the microcomputer 150 in the image acquired by the fixed camera unit 120a, 120b, 120c, 120d and the motion detection position information by the moved detection method. It works. For example, in the detection image of the fixed camera unit 120a, 120b, 120c, or 120d for detecting, when detecting a vehicle or a pedestrian traveling in the near direction at a long distance, it is pursued, and only the license plate of the vehicle or the face part of the pedestrian is detected. It selectively detects and selects and tracks and enlarges the position of the selected license plate or face image for a predetermined time and stores the enlarged license plate and face image as a still image.

In this case, the image acquisition unit may be configured to acquire the image by controlling the rotating camera unit 130 so that the license plate or the face area of the selected vehicle is enlarged and photographed. When the image acquisition unit detects a moving object in the detection image of the fixed camera units 120a, 120b, 120c, and 120d, the rotating camera unit 130 tracks the object and enlarges a specific part such as a face of a person or a license plate of a vehicle. To control. It also controls to track the enlarged image and store it as a still image. Therefore, the rotating camera unit 130 can shoot at a long distance, move to a desired position in one operation, and has an area zoom mode control function to simultaneously drive zoom in and zoom out.

On the other hand, when detecting a plurality of moving objects in the image captured by the fixed camera unit (120a, 120b, 120c, 120d), optionally, for example, to calculate the fastest moving object first, to enlarge it and store it as a still image Can be. The selected object is then calculated to perform shooting in turn.

In addition, the rotation camera unit 130 may detect the area of the fixed camera unit 120a, 120b, 120c, or 120d that the fixed camera unit 120a, 120b, 120c, or 120d may detect by setting a time period. The camera can be rotated to capture blind spots. For example, the lower part of the place where the intelligent video security system is installed cannot be detected due to the limited shooting angles of the fixed camera units 120a, 120b, 120c, and 120d, but the rotating camera unit 130 detects at a predetermined time period. In addition, the detected blind spots can be prevented from being transmitted and stored.

On the other hand, the microcomputer 150 is connected to a signal control unit capable of wired and wireless transmission and reception of electrical signals through an RF unit, RS-485 communication, etc., as well as being able to control from the outside as well as the center of the recorded video and still images The image transmission device 160 is combined to be transmitted to the center 170.

First, a digital image is acquired by a plurality of fixed camera units 120a, 120b, 120c, and 120d for detecting a set surveillance area such as a road or an alley, and the obtained image is obtained by a microcomputer of the local system 180 in real time. It is transmitted to the central center 170 via the image transmission device 160 via the 150 or the control unit. In addition, the image may be transmitted to the central center 170 in real time and stored in the memory 152 of the local system 180. The central center 170 may control various screen divisions and entire screens according to the number of images acquired. At this time, when a moving object is detected in the video acquired by the fixed camera unit 120a, 120b, 120c, or 120d, the motion detection camera system of the intelligent video security system and the motion detection position information by the motion detection method are based on the information. The moving object is enlarged, and the enlarged image is stored as a still image file and then transmitted to the central center 170. Therefore, the transmitted file is stored in the image database 175 together with the serial number, the shooting date and time, and the like. Since the image file is large, it is compressed and saved. The central center 170 calculates the corresponding vehicle number inquiry, image output, and various statistical data using the transmitted vehicle data, and transmits and receives data between the central center 170 and the local system 180 and controls the local system. To perform.

In addition, the rotation camera unit 130 detects an area that the fixed camera units 120a, 120b, 120c, and 120d cannot detect according to a set time period, for example, a portion directly below the place where the intelligent video security system is installed. Can be set to do so. That is, even a portion corresponding to a conventional blind spot can be detected at a predetermined time period, thereby eliminating the blind spot. The central center 170 may initialize various devices of the local system 180 or set up a captured image, and configure an image control module 172 for controlling an interruption or crime prevention PTZ camera.

On the other hand, the microcomputer 150 may transmit a warning broadcast and a guide broadcast through the speaker in the event of a violation in connection with the speaker having an amplifier. In addition, when the surveillance camera unit photographs at night, shooting may be facilitated by turning on a lamp in which the degree of light emission is controlled by a dimmer or an illuminometer according to the condition.
