![]() The popular video compression standards are MJPEG, MPEG4, and H.264 (also referred to as MPEG4-AVC). It is huge and, it represents the bandwidth requirement of just one content generating source (a surveillance camera, in this case).Īlong comes video compression, and the bandwidth requirement starts getting manageable. This is the raw data bandwidth requirement. 720 x 480, and transmitting at 30 fps (frames per second) the relevant numbers add up as follows: If we take a camera capturing an image at D1 (DVD) resolution, viz. Bit Rate = Frame Size * Frame Rate (fps).Frame Size = Resolution * Colour Depth (Chrominance/Luminance information).There are additional factors such as audio bandwidth and protocol (communication and compression) overheads but, these do not add significantly to the bandwidth. One question in the minds of many users and potential users of video surveillance is, How do I calculate the quantum of data generated by a surveillance camera and what is the bandwidth required to stream live video stream to remote viewers?Ĭalculating the approximate bandwidth of a video stream is a matter of multiplying the resolution of the captured image with the number of frames for the moving image.
