The present invention relates to a security management system and method using video technology, which can issue a warning and take appropriate action on an object repeatedly detected within a preset time interval.

Meanwhile, the present invention may be named an intruder prevention system, a crime prevention system, or a safety management system in that it warns intruders, prevents crimes, and ensures safety.

Hereinafter, various embodiments of the present invention will be described in detail with reference to the attached drawings.

FIG. 1 is a schematic diagram illustrating a security management system according to one embodiment of the present invention, and FIG. 2 is a block diagram illustrating the configuration of a security server according to one embodiment of the present invention.

Referring to FIG. 1, the security management system of the present embodiment may include an image acquisition device (100) and a security server (computing device, 102).

The image acquisition device (100) is a CCTV, camera, etc., and can monitor a preset area. For example, the image acquisition device (100) can monitor an object (104) within the preset area. Here, the object (104) is a person or an object.

Such image acquisition devices (100) can be installed in precious metal specialty stores, ATM (CD machine) installation locations, major national facilities, residences of women living alone, vulnerable areas at night, etc.

The security server (102) is connected to at least one image acquisition device (100) by wire or wirelessly, and may include a communication unit (200), a data processing unit (202), an alert unit (204), and a storage unit (206).

The data processing unit (202) analyzes the image transmitted from the image acquisition device (100) via the communication unit (200) to detect an object (104). If the same person is repeatedly detected as the object (104) within a preset time interval, the person may be determined to be suspicious. The operation of the data processing unit (202) may be performed by artificial intelligence (AI). This identity may be determined through singular points, facial recognition, body size (height), clothing/hat color, or gait.

The warning unit (204) can output a warning message through the image acquisition device (100) or a speaker, display, or light-emitting element installed at the relevant location, based on the decision of the data processing unit (202). That is, the warning unit (204) can control the speaker or display to output a warning sound or warning guidance on the screen, or control the light-emitting element to output a specific light by blinking. Of course, such a function can also be implemented by being included in the image acquisition device (100).

For example, the warning unit (204) can output warning messages such as "You are currently being recorded by CCTV", "You are currently being filmed by a camera; please refrain from approaching the building/store", etc., through the video acquisition device (100) or a speaker or display installed at the location. As a result, it is possible to prevent theft of expensive items, prevent crimes against women, and provide safety for major facilities.

In addition, if the same person is continuously detected within the preset area despite these warnings, the warning unit (204) outputs a warning message again through the image acquisition device (100) or a speaker or display installed in the relevant location, and the data processing unit (202) can transmit the image and analysis results to the manager's terminal, police station server, 119 emergency service server, etc. As a result, the manager, etc. can take appropriate measures.

Of course, the object detection results by the data processing unit (202), images, programs, warning messages, etc. transmitted from the image acquisition device (100) can be stored in the storage unit (206).

According to one embodiment, the security server (102) may record images through the image acquisition device (100) during the first time period, but may not perform the above-described warning operation, and may perform the above-described warning operation, etc. together with image recording during the second time period. For example, the security server (102) may not perform the warning operation during the time when people are at work (the first time period), and may perform the warning operation during the late-night hours after work (e.g., from 9 PM to 6 AM, the second time period). Therefore, there is no need to perform an object detection process, etc. during the first time period. Of course, if necessary, such as at the request of an administrator, an object detection process, etc. may also be performed during the first time period.

In summary, the security management system of this embodiment can output a warning message and contact an administrator or the like if the same object (104) is repeatedly detected within a preset time period. Consequently, the security management system can ensure the safety of the area where the image acquisition device (100) is installed.

In the above, the data processing unit (202) determined that the object (104) was a suspicious object when it was repeatedly detected. However, if the object (104) is a pre-registered object, it can be determined as a legitimate object even if it is repeatedly detected. Consequently, the warning unit (204) may not output a warning message. At this time, in order to determine whether it is a suspicious object, the data processing unit (202) can compare the detected object with information about the pre-registered object called from the storage unit (206) to determine whether the detected object is a pre-registered object or a suspicious object. Consequently, unnecessary warning guidance can be prevented.

In the above, the data processing unit (202) determined that the object (104) was suspicious through repeated detection. However, even if the same object is repeatedly detected, it may not be determined as a suspicious object if it does not exhibit suspicious behavior. For example, if a scene of a specific person cleaning is continuously filmed, the data processing unit (202) determines that the person is cleaning and not a suspicious object, and as a result, the warning unit (204) may not output a warning message. The behavior of such an object can be detected through behavior analysis of the object (104) from an image transmitted from the image acquisition device (100). For example, the data processing unit (202) can analyze the image to track the joint movements of the object (104) and analyze the behavior of the object (104).

According to another embodiment, if an object (104) is detected once but behaves suspiciously, the data processing unit (202) may determine that it is a suspicious object, and the warning unit (204) may output a warning message.

According to another embodiment, when the data processing unit (202) determines that an object is suspicious, the warning unit (204) may output a warning message based on the determination, but may sequentially output warning messages with different contents. At this time, the warning messages may be determined based on the behavior of the suspicious object. That is, the data processing unit (202) may detect the behavior of the suspicious object, and the warning unit (204) may output a warning message that matches the detection result. Consequently, if the behavior of the suspicious object changes, the contents of the warning message may also change. Such warning messages may be pre-registered or may be determined on the spot by AI. For example, when a suspicious object is detected, the warning unit (204) may always output the same warning message and subsequently output a different warning message based on the behavior of the suspicious object.

According to another embodiment, when the data processing unit (202) detects a suspicious object through image analysis transmitted from the first image acquisition device (100), the data processing unit (202) may also operate a second image acquisition device near the first image acquisition device (100) to monitor the suspicious object. As a result, even if the suspicious object leaves the surveillance area of one image acquisition device (100), continuous tracking may be possible. To this end, the second image acquisition device may rotate or perform operations such as zooming in/out. Of course, the first image acquisition device (100) may also perform zooming in/out operations. Since objects are not clearly visible at night, etc., if the data processing unit (202) determines that the object is suspicious, the first image acquisition device (100) may zoom in to clearly identify the face, etc., of the object. In this case, while the data processing unit (202) controls the first image acquisition device (100) to zoom in, the warning unit (204) can output a warning message.

According to another embodiment, the data processing unit (202) may comprehensively analyze images transmitted from a plurality of neighboring image acquisition devices (100) to detect a suspicious object. That is, the data processing unit (202) may not determine that an object is suspicious through analysis of an image transmitted from a single image acquisition device (100), but may determine that an object is suspicious through analysis of images transmitted from a plurality of image acquisition devices (100). In this case, the warning unit (204) may output a warning message based on the determination.

Figure 3 is a flowchart illustrating a security management process according to one embodiment of the present invention.

Referring to FIG. 3, the data processing unit (202) checks the current time (S300) and determines whether the current time is within a specific time period (e.g., late at night) (S302).

If the current time is not within the specific time interval mentioned above, for example, if it is daytime, the data processing unit (202) can activate the video recording mode and record the video acquired through the video acquisition device (100) (S304 and S306).

On the other hand, if the current time is within the specific time interval, the data processing unit (202) can activate the safety mode and monitor the preset area through the image acquisition device (100) according to the safety mode to detect a suspicious object, and the warning unit (204) can output a warning message (S308 and S310).

In summary, the security management method of the present embodiment can perform an operation of detecting a suspicious object and outputting a warning message during a specific time period, and can only perform a surveillance operation or a video recording operation without performing the suspicious object detection and warning message output operations during a time period other than the specific time period.

Figure 4 is a flowchart illustrating a security management process according to another embodiment of the present invention.

Referring to FIG. 4, the image acquisition device (100) transmits an image captured of an area under surveillance to a security server (102), and the data processing unit (202) of the security server (102) analyzes the transmitted image to detect an object (104) (S400 and S402).

Next, the data processing unit (202) can determine whether the same object is repeatedly detected through the image analysis (S404). Here, the identity can be determined through singularity detection, facial recognition, body size (height), clothing/hat color, or gait.

Continuing, if the data processing unit (202) detects a repetitive object and determines that it is a suspicious object, the warning unit (204) can output a warning message through the image acquisition device (100), speaker, display, or light-emitting element (S406).

In summary, the security management method of the present embodiment can determine an object that is repeatedly detected as a suspicious object and output a warning message.

Figure 5 is a flowchart illustrating a security management process according to another embodiment of the present invention.

Referring to FIG. 5, the data processing unit (202) can analyze the image transmitted from the image acquisition device (100) to detect an object (104) (S500).

Next, if the data processing unit (202) determines that the same object is repeatedly detected and is a suspicious object, the warning unit (204) can output a warning message (S502).

If the image acquisition device (100) malfunctions during such surveillance operations, the data processing unit (202) may transmit information about the last detected object or related images, etc. to an administrator, etc. (S506). Here, the data processing unit (202) may determine that the image acquisition device (100) malfunctions if no images are transmitted from the image acquisition device (100) for a predetermined period of time.

In summary, the security management method of the present embodiment can transmit information about the last detected object, etc., to an administrator or the like in the event of a failure of the image acquisition device (100). Of course, the security management method can also transmit information about the failure to an administrator or the like.
