Advanced Camera Bandwidth Test Results

Author: Ethan Ace, Published on Aug 12, 2013

[WARNING: If you think surveillance is all about 'leadership' and 'salesmanship', leave now. This in-depth technical report exposes never revealed patterns significantly impacting bandwidth and storage.]

There's much more going on than might appear. Surely you are aware of the relationship between resolution and bandwidth. Hopefully, you also understand the impact of compression levels even with the same resolution. Many of you also know that bandwidth can vary depending on the scene (think stairwell vs. intersection).

Our testing started off with some experiments with the same scene but different FoV.

For instance, compare the images below. Which of these scenes consumes more bandwidth?

How about these?

We continued with more experiments. How about sharpness?

We went further testing the bandwidth impact of varying:

  • Contrast
  • Brightness
  • Color
  • Focus
  • WDR

Some of them were fairly constant, but many produced massive swings in bandwidth consumption. Even more fascinating, the results often varied across camera lines tested including Axis, Avigilon, Bosch, Dahua and Sony.
