WDR CCTV Camera Dubai

WDR stands for Wide Dynamic Range. WDR are very commonly used in CCTV Security Surveillance application.  WDR feature in a CCTV camera is meant to provide sharper images in back light scenarios where you have both bright and dark areas.  In short, WDR camera is used where field of view has wide range of lighting scenarios. WDR CCTV Camera Dubai.

WDR cctv cameras are commonly used in surveillance cameras and in some medical applications. In surveillance, WDR cctv camera allows a camera to filter the intense back light surrounding a subject and thus enhances the ability to distinguish features and shapes on the subject. WDR CCTV  cameras are usually recommended for situations where light enters a premise from various angles such as a multi-window room. A camera placed on the inside of the room will be able to see through the intense sunlight or artificial light coming in. If an indoor security camera is pointed towards a window or an entrance door, you will see the background washed out during daytime. This is very common situation in restaurants and stores which have big glass windows.

In a scene with extremely bright and dark areas or in backlight situations where a person is in front of a bright window, a typical camera would produce an image where objects in the dark areas would hardly be visible. Wide dynamic range solves this by applying techniques such as using different exposures for different objects in a scene to enable objects in both bright and dark areas to be visible. WDR CCTV Camera Dubai  Below is an example of a wide dynamic range image WDR CCTV Camera Dubai , and the two different images it is created from, the overexposed image and underexposed image.

WDR cctv Cameras provides an excellent solution for many CCTV security applications. Many indoor locations like bank, retail stores, office, etc. have wide range of area because of windows. So during the day it becomes very difficult to view images properly. WDR cctv  cameras Dubai reduce such dark and bright area wide range effects.

WDR – Dynamic Contrast

WDR – Dynamic Contrast, the camera performs an advanced tone mapping, where some brightness levels are dropped to decrease the bit depth to a format that a computer screen can handle. In this tone mapping, both the darkest and the brightest parts are taken into account, resulting in more details on both ends.

WDR – Dynamic Capture

WDR – Dynamic Capture works by acquiring several images with different exposure times for each image. These pictures are then combined in a composite, where both the brightest and the darkest parts are kept, resulting in an image with exceptional clarity and sharpness.

WDR – Forensic Capture

WDR – Forensic Capture optimizes video for forensic purposes by enabling an extremely high level of detail to be visible in both dark and bright areas of a scene. It is the result of years of development at Axis combined with the best imaging components on the market. An Axis camera with WDR – Forensic Capture applies advanced algorithms to optimize image quality and includes the ability to seamlessly transition between WDR and low-light mode.

WDR Techniques

There are two basic techniques commonly used to successfully provide WDR capability:

Multi-frame imaging – In this technique the camera captures multiple frames of the field-of-view; each frame having a different dynamic range. The camera then combines the frames to produce one improved WDR frame.

Non-linear sensors – These are typically logarithmic sensors, where the sensitivity of the sensor at different illumination levels varies, enabling the capture of a wide dynamic range image in a single frame.

Of the two techniques, multi-frame imaging is the most commonly used by manufacturers supporting WDR capability for two main reasons.  First, it is superior at capturing images in real-time, and secondly  it can process moving objects more quickly than non-linear sensors. Multi-frame imaging is also more cost effective and integration friendly because it is far more common in the marketplace.. While non-linear sensors do perform well, they have not been widely adopted and current trends do not suggest this technique will overtake multi-frame imaging in popularity in the near future.
