How can we differentiate between Digital WDR and non Digital, since not all manufacturers do.

We discuss this in our WDR tutorial.

#1 Ask the manufacturer if the camera's WDR uses multiple exposures? If they do not confirm 'yes', then it's digital.

#2 Assume it's digital unless the manufacturer says explicitly otherwise. Most cameras marketed as WDR are digital only.

#3 If a line has multiple series with DVR, typically only the top one is 'true' WDR.

#4 Ignore dB ratings as they are self-reported and have a weak correlation to WDR performance.

If you are interested in a certain manufacturer, we can help verify / validate? For instance, here's our explanation of Axis digital vs multi-exposure WDR.
