When should WDR be used?
WDR is designed for environments with varying light conditions. For example, entrances are often exposed to strong light from the door but weaker light at the sides of the door. A camera with WDR will handle these environments well and lower the light in the entrance so that it is possible to see what is outside while the shadows inside become clear. When detecting licence plates, WDR can also be crucial as light from the car's headlights would otherwise obscure the plate.
How does WDR work?
Wide Dynamic Range (WDR) optimises the image in environments with a lot of backlighting or in shadowy areas. In bright areas, the exposure is reduced to avoid overexposed surfaces. Darker areas are given more exposure and brightened. When everything is combined, the result is a balanced image with much greater potential for identification. The technique behind this is that the camera takes an image with a higher dynamic range than can be presented. The camera then maps the image's colours and filters out certain light levels to finally present an image where both the lightest and darkest parts have been affected. The result is an image with more detail in both the lower and upper registers, a really good image!
What cameras does WDR have?
Generally, all cameras in AVTECH's premium series have WDR, i.e. cameras from the 5 and 8 series. Some of these have a digital WDR that is a little less efficient but still really sharp. Below are only the cameras with true WDR presented.
