1. A security surveillance system capable of outputting still images together with moving images, comprising:

  • an image acquisition unit for acquiring captured image signals from a plurality of cameras and outputting them;

    a surveillance image transmission unit for separating the acquired images into moving images and still images, and generating and transmitting surveillance images where the still images are separated at predetermined regular intervals; and

    a surveillance image reception unit for separately storing the moving images and the still images, reading a still image near a moving image output at a time when a signal requesting the output of the still image is received, and outputting the read still image, andwherein the surveillance image transmission unit comprises;

    an image reception unit for receiving images from the cameras;

    a moving image buffer for storing the received moving images;

    a still image buffer for storing still images at regular intervals;

    a moving image compression unit for receiving and compressing the moving images stored in the moving image buffer;

    a still image compression unit for receiving and compressing the still images stored in the still image buffer;

    a surveillance image generation unit for packetizing the compressed moving images and the compressed still images for transmission;

    a first interface unit for transmitting packets of the generated surveillance images; and

    a transmission control unit for controlling the elements for transmitting the surveillance images.
