Wide Dynamic Range (WDR)
Wide Dynamic Range technology mechanically allows capturing an entire scene in challenging lighting conditions. One shutter is set to a short exposure, capturing the bright areas in the FoV, while the other is set for a long exposure, capturing the dark areas in the FoV. The camera then interlaces the images and combines them, capturing both areas with no loss of detail. This allows for an image capture even when there are very bright and dark areas in the camera’s field of view or images are distorted by a strong backlight.
Smart IR™
Smart IR™ adjusts the image for IR cameras to eliminate LED light reflection and white spots in the image. By breaking down the camera’s field of view into five zones, Smart IR allows for even distribution of the IR light. This prevents excessive illumination on images that are in the front of the scene and offers a clear image in B/W without any loss of detail.
