It also take 5-20x the processing power of H.264, which is why it is usually limited to the lowest resolution cameras or HD cameras that only can record when they detect motion.īecause MJPEG files are so inefficient, MJPEG is really only used on cameras where you don't have to worry about storing lots of data. MJPEG has one clear advantage to everything else: It works in any browser!

MJPEG is a slow series of individually compressed pictures It's not exactly video, in the way that we normally think of video. If you ever wondered why a cheap low resolution camera can work in any browser but every professional camera system only works in Internet Explorer and Safari, then this guide is for you. There's three ways that professional security cameras record video (and one way that Google does ). What are MJPEG, H.264, and H.265? How do They Relate to Watching Security Cameras in a Browser?
