Some applications require IP cameras with a wide dynamic range (WDR). What is a wide dynamic range? It means that the video will look much better in situations where there are very wide light differences in the scene. You may have seen this type of problem, where you are viewing a person in front of a bright background. The background is clear, but the person is very dark and hard to see.

In this case, you can see the person but the background is lost in a bright haze. If there are people in the background you can’t see them. Today’s new IP cameras use a wide dynamic range to allow you to view both the foreground and background.Continue reading “IP Camera Test and Review of Wide Dynamic Range – Sony vs Samsung vs Hikvision”
