Testing Bandwidth vs. Frame Rate

By: IPVM Team, Published on Jan 23, 2019

Selecting frame rate has a major impact on surveillance bandwidth and storage consumption. But with smart codecs now common and cameras more efficient than ever, what is the "right" frame rate?

In this report, we tested 10 cameras from 3 manufacturers, testing framerates ranging from 1-30 FPS, with smart codecs on and off, using H.265 and H.264, in multiple varying complexity scenes.

Inside, we give our key findings and two key recommendations for optimizing surveillance framerates.
