Forensic WDR
Capture clear, detailed color video in scenes with both dark and bright areas—even when there’s motion. Forensic WDR reduces visible noise and artifacts for maximum forensic usability. It’s also suitable for use with high-resolution cameras.
Forensic details in challenging light
A scene with extremely bright and dark areas has what’s called wide dynamic range, and it can spell serious trouble for image usability and clarity. Images may be underexposed or overexposed, making it impossible to identify objects and people. Fortunately, Axis cameras with WDR (Wide Dynamic Range) technologies can mean the difference between seeing important forensic details clearly and seeing nothing, or just a blur. They ensure you can place your cameras exactly where you need them, with no need to worry about difficult lighting.
Great forensic usability
Forensic WDR captures clear details in scenes with both dark and bright areas. It’s extremely good at dual capture, merging both long and short exposures, and delivers strong tone mapping, especially in dark parts of the scene when combined with Axis Lightfinder technologies. This keeps noise low and reduces bitrate. Axis cameras with WDR technologies can mean the difference between clearly seeing important forensic details and seeing nothing but a blur. Using the latest image processing algorithms, it ensures accurate colors and automatically adapts to changing light conditions. It can also work with Axis OptimizedIR to produce clear, detailed images, even in total darkness.
Good results, even in scenes with motion
Axis WDR technologies are fine-tuned for scenes with motion, where they ensure less image blur. They prioritize shorter exposure time which effectively reduces visible noise and avoids artifacts. Compared to older techniques, these technologies are ideal for use with high-resolution cameras. Axis also offers products with other WDR technologies (WDR - Forensic Capture, WDR - Dynamic Capture, and WDR - Dynamic Contrast), each optimized for specific circumstances. In addition, Axis Forensic WDR technology uses advanced imaging algorithms with improved merging capabilities to effectively select how to use the long and short exposures. So, it avoids pixels with unnecessarily high noise level to ensure fine-tuned video for maximum forensic usability.
Great performance
Axis Forensic WDR is built into Axis cameras powered by our high-performance, high-throughput system-on-chip and imaging algorithms. It ensures great performance even at full frame rate in up to 4K at 60 fps. And thanks to our expertise in tone mapping, you can rely on clear, detailed images even when viewing your video on a regular, non-WDR monitor.
Choosing the best WDR camera
So how do you pick the best WDR camera for your needs? One way to gauge a camera’s ability to handle images with wide dynamic range is its dB value. Conventional wisdom says the higher the dB, the clearer the image. But that’s only part of the story. Axis always prioritizes forensic usability and image quality over achieving high dB. Because other variables – like the quality of image processing – play an important role as well. The bottom line? A camera with a lower dB value can produce an image that’s better for video surveillance.
