WDR stands for Wide Dynamic Range, is a technology used on video cameras to compensate problems with light exposure. It can work on the dark and bright areas on the image and create a balance to improve the overall image quality.

Fortunately, Axis cameras with Wide Dynamic Range (WDR) technology make the difference between seeing important forensic details clearly, and seeing nothing but a blur. Without WDR technology, images may be underexposed or overexposed, making it impossible to identify objects and people.

This white paper explains the technology behind the limited dynamic range of a camera, describes the available general methods for achieving good WDR performance, and presents Axis WDR solutions for video with maximal forensic value and usability.

Nov 30, 2023 · When activated, you’ll notice dark spots and glare are no longer a problem for security cameras. In essence, WDR manages those extremes of the light spectrum to a level that provides the most detail possible when reviewing or streaming video footage.

HDR and Digital WDR (DWDR) mean the same thing. It’s software that helps the camera in challenging lighting conditions. True WDR is both digital and hardware and helps the camera …

Oct 31, 2014 · What is Wide Dynamic Range (WDR)? Glare is a very common problem for security cameras. Due to the environments in which they are commonly installed, it’s a frequent occurrence to be dealing with or adjusting for glare.

Jan 25, 2025 · Wide Dynamic Range (WDR) is a technology found in imaging devices, particularly in CCTV cameras, designed to optimize the capture and reproduction of images in environments where lighting conditions vary significantly.

Oct 29, 2024 · Wide Dynamic Range (WDR) is an excellent tech used in cameras and sound systems. It helps them grab an extensive range of colors, tones, and sound levels. Handling scenes or recordings with a significant contrast between extremely bright and dark parts.

Sep 10, 2024 · What is WDR, and Why Does It Matter in Security Cameras? Wide Dynamic Range (WDR) is a crucial technology in modern security cameras. It’s designed to bridge the gap between extremely bright and dark areas within a scene, ensuring that both are visible in the captured footage.

DWDR or Digital wide dynamic range is a software-based technique that enhances the image quality by adjusting the gamma value to brighten dark areas. True WDR is a sensor-based technology. A True WDR CCTV can produce images with an extremely wide dynamic range.
