Digital video is the technology of storing and transmitting CCTV images in digital format using IP networking. Video images are digitally encoded using standard CODECS such as Motion JPEG, M-PEG4 or H.264 and transmitted over IP networks and stored. With Digital video, the video stream is digital and not simply the recording medium. By comparison, for example, DVR technology is a digital recording medium and doesn't imply that the video stream is digital.
