Description

Closed Circuit Television System Using Web Phone

The present invention relates to a CCTV system using a web phone, and more particularly, when a motion is detected, a server carrying a web phone is monitored by outputting a video signal along with a motion detection message from a server to a web phone connected to a network. It is about a CCTV system using a web phone that can notify the user immediately that a movement has been detected due to theft or intruder even when he is away.

In general, CCTV system is installed in general houses, department stores, banks, factories, and exhibition halls to prevent theft and to easily check the operation status and process flow of machinery, and to be installed at major intersections. The conventional CCTV system, as described above, refers to a device that is also used to identify a device through one or more video cameras (1) and a video camera (1) for capturing a surveillance target, as shown in FIG. The multiplexer 3 converts the captured images one by one in order and outputs the images, the monitor 5 outputting the image captured by the video camera 1 to the screen, and the image captured by the video camera 1 are later reproduced. It consists of a VCR (7) for recording the image output from the multiplexer (3) so that you can see.

When a motion is detected in the conventional CCTV system as described above, alarm list recording is performed, a buzzer or an alarm is generated to inform the monitor that an alarm has occurred, and the video signal input from the video camera 1 is monitored (5). ) So that the monitor can check it. In addition, the VCR 7 is controlled so that the recording can be performed so that it can be checked later.

However, as described above, if the monitor is not looking at the monitor even when the alarm occurs, only the recording is performed on the VCR without knowing that the alarm has occurred. Therefore, in the above-described case, a problem arises in that it is not immediately recognized that an alarm has occurred and a search for a tape of a recorded VCR later determines whether theft and unauthorized intrusion are made. In addition, even when the watcher keeps watching the monitor and immediately recognizes that an alarm has occurred, there is a problem that the watcher does not know where the intruder moves while moving to the alarm generating area to catch the intruder.

The present invention has been made to solve the above-mentioned problems, by implementing a CCTV system using a web phone, even if the monitor is away, even if theft or intruder can immediately know that the movement is detected and the movement is detected The purpose of the present invention is to provide a CCTV system using a web phone to view the video signal on the go.

CCTV system using a web phone of the present invention for achieving the above object is connected to a wired LAN, the camera to detect the movement by taking a monitoring target, and having an assigned IP address; A VCR for recording a video signal output from the camera; A web phone connected to a wireless LAN and having an access point for receiving data wirelessly and an assigned IP address, and receiving the video signal through a network; And a server having an access point for monitoring the camera and sending the video signal received from the camera to the VCR and transmitting data wirelessly to the web phone.

Hereinafter, a CCTV system using a web phone according to a preferred embodiment of the present invention with reference to the accompanying drawings will be described in detail.

2 is an exemplary view showing the configuration of a CCTV system using a web phone of the present invention. As shown in this figure, the CCTV system using the web phone of the present invention is connected to a wired LAN (Local Area Network) to take a picture of the monitoring target to detect the movement, the assigned IP address (Internet Protocol Address; TCP / IP It is a 32-bit address used in a network by a protocol, and records a video signal output from the web camera 10 and the web camera 10 having a decimal number and a dot as in 128.1.1.1). Like Time Lapse VCR 20 and Web camera 10, it has an assigned IP address, has an Access Point 31 that can be connected to a wireless LAN to receive data wirelessly, and can be connected to the Internet or TCP / IP. It monitors the web phone 30 and the web camera 10 that can receive voice and video signals through the network based on it, and sends the video signal received from the web camera 10 to the Time Lapse VCR 20, the web phone. Wireless to 30 It consists of a server 40 having an access point 41 for sending data to.

On the other hand, to switch from wired LAN to wireless LAN, change the PCMCIA (PC Card) or ISABUS wired LAN Card to RANGELAN2 / PCMCIA and then change the driver to RANGELAN2 / PCMCIA Ethernet / Token Ring driver.

The RANGELAN2 driver described above includes all types of Windows versions (e.g. Windows'95 and Windows NT), DOS, Network Driver Interface Specification (NDIS), and network interface cards and device drivers that do not depend on hardware or transmission media. ), ODI (Open Data-Link Interface) specification for network interface cards and device drivers that do not depend on hardware or transmission media, and packet drivers. These drivers support various network operating systems (NOS) and protocol stacks (Netware, Vines, TCP / IP, Lantastic, LAN server, etc.) to help users use a variety of network applications.

Hereinafter, a CCTV system using a web phone of the present invention according to a preferred embodiment.

The video signal captured by the web camera 10 installed in place is transmitted to the server 40 through a network, and the server 40 monitors each web camera 10. As described above, when a motion is detected while monitoring the web camera 10, the server 40 receives alarm information indicating that the motion is detected together with an image signal from the web camera 10. The server 40 receiving the video signal and the alarm information from the web camera 10 calls the web phone 30 having the corresponding IP address through the access point 41 of the server 40. At this time, the server 40 outputs a simple motion detection message to the web phone 30, and then transmits the video signal received from the web camera 10 to the web phone 30.

Therefore, the monitor receiving the data transmitted to the web phone 30 can cope with theft and unauthorized intrusion as soon as the motion is detected, and can monitor the image transmitted from the web camera 10 while moving. In addition, it is possible to see whether the detected motion is due to an error through the video signal, thereby preventing unnecessary actions of the monitors. In addition, since data is transmitted using the existing LAN, additional service burden is reduced, and cable compensation is unnecessary because the data is transmitted through the LAN.

CCTV system using the web phone of the present invention is not limited to the above-described embodiment can be implemented in various modifications within the scope of the technical idea of the present invention.

According to the CCTV system using the web phone of the present invention as described above, when a motion is detected by implementing a CCTV system using a web phone, the server outputs a video signal along with a motion detection message to a web phone connected to the network. As a result, even if a watcher who carries a web phone is away from the office while monitoring, theft or intruder may be immediately detected that the movement is detected. In addition, the image signal transmitted from the camera from which the motion is detected can be seen even during the movement, and thus there is an effect of quickly coping with the changing situation.
