Your IP Video Surveillance Cheat Sheet: Wide Dynamic Range
WDR-enabled cameras address security video lighting challenges so the images your system captures are clear.
Here is an example of WDR in action. The camera perfectly captures an osprey with a lizard in its talons despite direct sunlight shining into the camera's field of view.
One challenge that often arises with video surveillance systems is the inability of standard IP cameras to capture clear video in situations where there is a significant variance in lighting levels within a single scene. Often a security camera’s field-of-view encompasses both very bright and very dark areas simultaneously. When this occurs, standard surveillance cameras can’t simply adjust their iris settings or shutter speeds to optimize the amount of light that will produce viable image quality. Too much light, and the image is blown out; too little light, and the image is dark.
Fortunately, technologies to compensate for Wide Dynamic Range (WDR) have been developed to address this problem. Although such specialized technologies have often been costly in the past, end users and integrators are in luck. WDR security cameras are now more affordable than ever and can provide usable footage of security incidents regardless of their location.
In this cheat sheet, we will cover the situations that are most appropriate for the deployment of WDR-enabled cameras, as well as some tips and tricks that will help you optimize the performance of your WDR security cameras.
