Abstract	There are so many CCTV in our streets, buildings and public places. Nevertheless, security methods for CCTV are rarely. This paper describes a study on developing a media crypto algorithm for anti-hacking into CCTV. H.264 codec is used to compress the video stream in CCTV systems. HIGHT algorithm provided by KISA is adopted as a crypto algorithm in our development. Other crypto methods except HIGHT could be selected by company's security police. Only some bytes in VCL(Video Coding Layer) of H.264 are encrypted to improve the performance of limited platforms, such as CCTV, WebCam, smartphone. Very fast and light crypto algorithm was developed by our researches.
