Camera Color Fidelity Shootout

Author: Figen Bekisli, Published on Sep 04, 2013

The surveillance industry is obsessed with more and more pixels. But color fidelity - accurately rendering yellow as yellow or blue as blue - can be critical for identifying individuals or objects.

We decided to test 5 camera manufacturers - Axis, Avigilon, Bosch, Dahua and Sony - to see how faithful their cameras could reproduce color.

The Test

We used a ColorChecker (aka Macbeth chart) and shot out all cameras side by side simultaneously. Here's a preview of the results with the models blacked out.

This was a fairly simple low light indoor scene but still notice how much color fidelity varied across them.

Scenes

Moreover, we tested in a variety of conditions including different forms of outdoor street lighting to see how LED, mercury vapor, and sodium lights impacted performance.

We concluded with real world examples of a subject wearing different colored shirts.

Here's one example of a major manufacturer who made a range colors look basically the same:

Contrast to another major manufacturer who handled the same scene, same time dramatically better:

Who Won?

There were clear winners and losers here. Who was it? Was it Avigilon - who claims to deliver the best image quality? Axis - who touts their conformance with HDTV standards? Dahua - the up and coming Chinese company? Or did the old guard - Bosch or Sony pull it out? Answers and detailed analysis inside.
