Optimizing Bandwidth Consumption Through I Frame Settings

Author: John Honovich, Published on Feb 03, 2010

A blog post from Genetec offers an interesting example of lower level IP camera optimizations that can impact bandwidth utilization. Genetec claims such an optimization can lower bandwidth consumption by 2 to 3x.

The basic point is that some VMS systems allow you to adjust how frequently a full image is sent in a MPEG4 or H.264 stream while others have a fixed setting. By making the interval longer, you can reduce bandwidth consumption because the encoder/camera is just sending small updates rather than the whole picture.
