WDR (wide dynamic range) technology is vital in CCTV/IP cameras when a part of the image is very dark, and another part is bright. Without WDR, it may not be possible to see any details in the dark area.
WDR is particularly important for motion sensor security lights with cameras, especially those installed outdoors to monitor a porch. If your porch is shaded, while your pathway is sunny, the camera may get confused, reducing your ability to see details in both areas.
Unfortunately, most security cameras with lights for outdoor use do not come with the WDR function. Therefore, during hot summer months, your images may be blurry if you choose to install a motion security light with a camera.

By contrast, most professional security cameras, such as the 1NC-291 and 1NC-296 mentioned earlier, come with WDR enabled to provide clear images in both bright and dark areas.
