Whats the difference between MJPEG and H.264 IP camera

In order to transfer digital video across the internet, the camera needs to compress the video so that it saves bandwidth and view the video smoothly. There are 2 popular video compress types MJPEG and H.264.

What is MJPEG video compression?

MJPEG stands for motion jpeg (pronounced jay-peg). Jpeg is a compression format for images, so as you would expect, MJPEG is a compression format for video that stitches together a bunch of images and presents them as video. It seems like a series of images showed together in rapid succession that make it appear as though you are watching a full-motion video.

Advantages of MJPEG

MJPEG doesn’t require large amounts of processing power, so it’s commonly used in webcams and cameras for encoding and compressing video. This means that MJPEG IP cameras are often cheaper than H.264 IP cameras.

Disadvantages of MJPEG

The single biggest issues with MJPEG are video quality and bandwidth requirements. MJPEG doesn’t have the ability to provide a high-quality or even HD-quality image.

What is H.264 video compression?

H.264 (pronounced H dot 2 6 4) is now one of the most commonly used video compression formats, although most people don’t even know this. H.264 is used by Vimeo, Youtube, iTunes, Adobe Flash Player and Blu-ray Discs.

Advantages of H.264

H.264′s biggest advantage over MJPEG is that results in a better quality video feed using less bandwidth and that is because H.264 has the ability to adjust the frame rate (the number of frames being shown per second) so an H.264 IP camera watching a scene without much action uses less bandwidth because there is no need to use a high frame rate.

Disadvantages of H.264

H.264 requires more processing power than MJPEG which means that H.264 IP cameras tend to be a slightly more expensive than MJPEG IP cameras because they need to have more “brain power”.
