In general, CCTV systems can be installed at several places where security is required, and video signals received from the cameras can be displayed on multiple TV monitors in a single place, so that many places can be monitored simultaneously with a small number of surveillance personnel. In addition, the video signal received from the camera is recorded in a storage medium such as a VCR, which can be used as an important evidence in addition to helping to arrest the criminal in case of theft.

CCTV can be connected directly to a monitor or VCR when only one camera is used, but when using multiple cameras, signals from each camera are separated and transmitted to the monitor or VCR. In general, a CCTV system includes a selector for selecting a video signal to be displayed on a monitor, a screen splitter for displaying a plurality of separate video signals on a single monitor to reduce the number of monitors displaying the video signals, and recording the video signals. It is composed of a recording device for.

Since the video in the CCTV is recorded in analog form, there are some disadvantages. First, image processing is difficult. For the purpose of using CCTV, it is often necessary to examine the recorded video closely. In this case, since the image is recorded in an analog form, it is difficult to apply an image processing technique that is helpful for detailed investigation such as motion detection or object recognition.

In addition, it is difficult to transmit and receive video signals using a communication network such as the Internet. Moreover, since the video signal is recorded in a sequential storage medium such as a VCR, it is difficult to find a desired recording content quickly.

Recently, with the development of digital technology, a technique of digitizing and processing a video signal has been introduced. The system uses a DVR system to convert analog video signals input through the camera into digital signals, compressing and restoring video using MPEG, the international video compression method, to record and play back. The DVR has solved most of the shortcomings of the general CCTV described above. That is, since image data is stored in a digital form, various digital image processing techniques can be applied, and transmission and reception through a communication network is free. In addition, since it is mainly stored in a non-sequential storage medium, such as HDD, it is possible to random access (image random) to the image data to find.

However, there are other disadvantages with such DVRs. That is, due to the addition of the process of digitizing the analog signal, which is not available in general CCTV, the image displayed on the digital video monitor appears to be delayed slightly than the actual one, and when the speed of the image processor is not sufficient, the frame of the image displayed on the monitor The rate value drops and the screen appears to be discontinuously broken.

Therefore, there has been a demand for a new video display and recording system having only the advantages of a general CCTV using an analog video signal and a DVR using a digital video signal.

An object of the present invention for solving the above problems relates to a closed-circuit television (hereinafter referred to as CCTV) system that is a security video display and recording device, in particular, the image received from one or more surveillance cameras Moving images to digital video recording (hereinafter referred to as DVR), displaying necessary images on the digital image display unit, and simultaneously displaying some of the images on a commercially available camera phone or PDA. If you want to check the status of the six sides of the product during the work process or product shipment process, display the image acquired from the camera on a single screen in six split screens, and the status of each product or production process. DVR to make sure that A system to provide a wireless image transmission function 6 and a CCTV system with a drainage screen split function using.
