  • Security surveillance system capable of outputting still images together with moving images
    Patent number: 7889229
    Abstract: The present invention relates to a security surveillance system. The security surveillance system includes an image acquisition unit, a surveillance image transmission unit, and a surveillance image reception unit. The image acquisition unit acquires captured image signals from a plurality of cameras and outputs them. The surveillance image transmission unit separates the acquired images into moving images and still images, and generates and transmits surveillance images where the still images are separated at predetermined regular intervals. The surveillance image reception unit separately stores the moving images and the still images, reads a still image near a moving image output at a time when a signal requesting the output of the still image is received, and outputs the read still image.
