The present invention relates to a network camera using a binary CDMA and an aria encryption. The network camera includes: a first camera module which captures videos; an A/V codec which compresses images and sound of a video signal, output from the first camera module; a host processor which controls the first camera module and the A/V codec, performs a binary CDMA function and a function of recognizing a motion and flames with respect to image processing data, and controls to transmit data, obtained by aria-encrypting the video signal, compressed by the A/V codec, or the data of sensing; an image processing unit which image-processes the video signal, output from the first camera module, into data and provides the data to the host processor; an aria encryption module which encrypts the video signal, compressed by the A/V codec, or the data of sensing into data by using an aria algorithm and provides the data to the host processor; a binary CDMA base band processor which encodes the aria-encrypted data under the control of the host processor, binarizes the encoded data, and modulates the binarized data into a time-division multiple access signal waveform; and an RF transmission module which transmits the modulated signal, output from the binary CDMA base band processor, as an RF signal. According to the present invention, as a binary CDMA wireless communications technology is used, a processing speed and stability can be increased; a transmission distance can be extended; and convenience and monitoring reliability can be increased by processing an obtained image. |
