Monitoring and Security System Based Realtime Multi-channel Video}

The present invention relates to a real-time multi-channel video-based surveillance and security system, and more particularly, real-time multi-channel that can perform a security task on the go by transmitting the real-time video transmitted from the surveillance camera to the portable display device through wireless communication A video based surveillance and security system.

Today, security video systems have been installed in factories or critical facilities in a rapidly changing industrial society. Today, security video systems are used in various ways to improve the quality of life, to protect the security of anxiety and to protect personal property. It is developing rapidly, and demand is also increasing by maintaining a close relationship with daily life. In particular, the scope of construction has been expanded from crime prevention and accident or risk prevention to public safety, such as subway safety, traffic information collection, facility management, disaster management, and parking management.

Conventional video systems for security can be classified into a wired method and a wireless method according to the data transmission method, the wired method currently occupies about 80% market. However, while wired security video system can process image source stably, installation of cable wiring work, duct work, plumbing work etc. is essential for the installation, and it may not be easy to install due to the structure of the installation site, and the installation cost is high. There is a problem. In particular, additional costs and difficulties are required to maintain and maintain the installed system, such as the risk of breakage of exposed cables.

1 is a conceptual diagram of outputting image data to a monitor using a conventional network display server.

As shown in FIG. 1, the analog video server 10 receives image data received from a plurality of cameras and transmits the image data to the network display server 20. Then, the network display server 20 reproduces the image data and outputs it to the monitor. As such, the analog video server 10 has a problem in that it requires only long distance transmission, and thus requires a low image quality, a low transmission frame, and a separate network display server 20.

2 is a block diagram of a digital audio / video transmission system disclosed in Korean Laid-Open Patent Publication No. 2005-0090788.

As shown in FIG. 2, a digital video streamer (DVS) 30 and a digital video distribution amplifier (DVDA) which are the most basic components of a network-based A / V transmission system for security surveillance are shown. As an example of a device having an amplifier 40 and which can be further interfaced to the DVDA, a conventional analog CCTV device, the matrix 42, the multiplexer 44 and the hybrid DVR 50 is shown. It is.

In this case, the DVS 30 is built into the camera and is designed as a DVS integrated digital video camera (DVC) 60. The network-based digital A / V transmission system outputs both analog A / V signals output from a plurality of surveillance devices such as a video camera 32 and a microphone, and a plurality of control signals such as a camera Pan / Tilt / Zoom controller. After converting the digital data into the digital data, it is basically configured to transmit it to the DVDA 40 through the network hub. In addition, the DVDA 40 converts the received digital data into an analog signal and inversely outputs the analog CCTV device such as the matrix 42 or the multiplexer 44, as well as the conventional DVR 55, and the built-in. The digital data transmitted through the hub may be directly transmitted to the hybrid DVR 50 as it is.

However, the Patent Publication No. 2005-0090788 transmits and receives data by connecting a plurality of terminals to one hub. Therefore, it is impossible to connect a plurality of DVDAs located elsewhere, and the cost and complexity of installation due to wiring between the hub and the camera or between the hub and the plurality of DVRs are required. Accordingly, a more efficient system configuration is required by solving the problems of wiring cost and data transmission efficiency according to the conventional system configuration.

In addition, Korean Patent No. 0742392 relates to a digital wireless monitoring system and a method thereof, and performs MPEG-4 encoding processing on an image signal captured by a camera using an MPEG-4 codec for each frame, and MPEG-4 encoding. The video signal for each frame is processed again by an encoder that excludes an audio signal and compresses only the video signal, and includes information about each transmitter and information about a communication standard in the video signal for each frame that is encoded twice. A plurality of transmitters for combining a header to form a file and transmitting a file including header information formed for each frame to an AP using different channels; An AP that receives a file including header information for each frame transmitted simultaneously through different channels from a plurality of transmitters, and transmits a corresponding file received from a plurality of transmitters to a receiver having a fixed IP address using a time division method; ; Receives a file containing header information for each frame photographed by a plurality of transmitters through the AP, decodes the corresponding file by decoding each filer by using the information included in the header of the file for each frame, and then multi-channel It is composed of a receiver that simultaneously plays the screen of the streaming viewer with the streaming viewer or streams the screen of one channel with the streaming viewer, and stores the video signal being streamed and reproduced for each transmitter in the designated storage space according to the storage operation of the administrator.

However, the registered patent No. 0742392 excludes an audio signal from each transmitter and separately encodes only an image signal photographed by a camera and transmits the data to the receiver through the AP, thereby greatly reducing the amount of data. Compared to transmission, video signals can be transmitted by using many channels at the same data rate at the same time. Therefore, the use of various channels and the range of use can be expanded. However, users are using time-division wireless signals. Increasing throughput greatly reduces the transmission speed, and the transmission speed also changes frequently, making it difficult to guarantee a certain speed at all times.

In addition, in the conventional monitoring system, since the camera operates 24 hours a day, a lot of power consumption and a lot of space for storing data have a problem in that the cost increases.
