Video Encode Type : H265,H264,MJPEG

H265:

        H.264, H.265 and VP8/9 are video in the way that we normally think of video. H.264/5 are even the type of files you watch when you are watching movies at the movie theater.

H264:

        H.264, H.265 and VP8/9 are video in the way that we normally think of video. H.264/5 are even the type of files you watch when you are watching movies at the movie theater.

Mjpeg:

        MJPEG has one clear advantage to everything else: It works in any browser! The problem is that it takes about 5-20x the hard drive space as H.264, which means that long term data retention is absurdly expensive. 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.

Because MJPEG files are so inefficient, MJPEG is really only used on cameras where you don't have to worry about storing lots of data.
