  • VIDEO CAMERA MONITORING SYSTEM AND CAMERA MONITORING METHOD THEREOF
    Publication number: 20110228093
    Abstract: A video camera monitoring system includes one or more cameras, a controller, a computer, a computer monitor, a video encoder, and one or more camera monitors. The cameras capture images and convert the captured images into video signals. The controller transfers the video signals to the computer. The computer monitor displays video images corresponding to the video signals. The computer selects a section of each of the video images and sends video signals corresponding to the section of each of the video images back to the controller. The controller compresses the video signals from the computer and transfers the compressed video signals to the video encoder. The video encoder encodes the compressed video signals into analog video signals. The camera monitors receive the analog video signals and display the video images of the analog video signals.

    Abstract: A monitor system includes at least one network camera distributed in an area to be monitored, an access point device connected to the at least one network camera. The access point device includes ports, a central processing unit (CPU), and a storage device containing an information table. Each of the ports is connected to the CPU, and the CPU is connected to the storage device. The table records a serial number, a media access control (MAC) address, and an area monitored by each camera in the system, and records an Internet protocol (IP) pool previously assigned to each monitored area. After an IP request from one of the cameras, the CPU searches an associated IP pool in the table according to the MAC address, and randomly assigns an IP address from the IP pool to a corresponding network camera.
