What's MPEG4?

MPEG4 's object-oriented compression method also makes the image detection function and accuracy more fully reflected, because the image detection function makes the hard disk recorder system have more excellent video mobile alarm function than before.

MPEG4 is a new low code rate, high compression ratio of video coding standards, the transfer rate of 4.8-64kbit/s, the use of storage space is relatively small, such as: for the definition of 352x288 color screen, each frame occupies 1.3KB, select 25 frames per second, Then an hour to 120KB, 10 hours a day, 30 days a month, then each month to 36GB, two roads to 72GB, four roads to 144GB if 8 is required 288GB, which is clearly acceptable to users.

MPEG4 compression principle and MPEG1, 2 different!

MPEG1, 2 file extension is mpg or mpeg! and MPEG4 is AVI, Microsoft's latest ASF format also uses the MPEG4 compression technology!

On the quality, MPEG2 is superior to MPEG4 but bulky, MPEG4 quality and volume more balanced, is a compromise solution!MPEG4 support streaming media playback!
