Motion JPEG (M-JPEG or MJPEG) is a video compression format where each video frame is compressed separately as a JPEG image. In network architecture, requesting an MJPEG stream requires fewer processing resources from the camera's internal CPU compared to rendering complex H.264 or H.265 streams. The presence of mjpg or motion jpeg in a URL typically points directly to the live payload stream of a camera feed. 4. free

Manufacturers often left an "open door" via the axis-cgi/mjpg/video.cgi path. If the camera admin forgot to flip the switch to "require digest authentication," that stream was broadcast to anyone who guessed the URL.
