Wide Dynamic Range Security Camera -
the perfect balance in lighting for one clear image

During daytime, the image produced by security cameras can be extremely washed out due to the high brightness of the incoming light. This effect is commonly seen in restaurants, stores, offices, and other buildings that have large windows or entrances. When part of a video image is dark and the other part is so bright you can’t see any details, it is called Dynamic Range — the difference in lighting. A Wide Dynamic Range Security Camera has sensors that allows the security camera to balance the difference in lighting for one clear image. Wide Dynamic Range (WDR) is one of the most popular features in IP Security Cameras. But, what is it and how can it benefit us?

Wide Dynamic Range : Technology

Wide Dynamic Range is a feature currently available in most security systems in order to balance out images that have a large dynamic range. Images taken by standard surveillance camera always seem to have an overexposed foreground or too dark of a background due to the limitation of the security camera image sensor sensitivity. Over the course of a day, the situation can change with different areas of the scene being over or underexposed. In these cases, to optain the best possible image quality, a Wide Dynamic Range Security Camera is recommended. Wide Dynamic Range Security Camera makes this possible by applying multiple exposure levels, contrast enhancement and advanced algorithms that lower noise and increase the image signal. With Wide Dynamic Range users are able to place their security cameras miami exactly where they need them, without having to worry about poor quality surveillance video image or difficult lighting.

Wide Dynamic Range : Types

There is no doubt that Wide Dynamic Range is an useful technology, as it facilitates clear images to be seen over light and dark areas in the same shot — rather than overexposing or underexposing various sections of the scene as with regular surveillance cameras without WDR technology. Wide Dynamic Range Technology is available in the following types:

Wide Dynamic Range (WDR)

Wide Dynamic Range technology allows security cameras to capture good quality pictures even under challenging light conditions. Wide Dynamic Range Security Camera maintains a proper image brightness, exposure, contrast and ensures image clarity. This function is available in both analog security cameras and digital IP security cameras. Wide Dynamic Range is measured in dB. A Wide Dynamic Range Security Camera with a WDR of 120 dB can catch a greater scale of brightness.

Digital Wide Dynamic Range

Digital Wide Dynamic Range (DWDR) is a software-based technique that optimizes image quality by adjusting the gamma (γ) value to enhance dark areas. A Digital Wide Dynamic Range Security Camera has the ability to view dark areas of the given image as well as extremely lighted portions of the image, or areas of high contrast. The level of DWDR ranges from 1 to 8 and should be adjusted carefully in a Digital Wide Dynamic Range Security Camera according to the lighting conditions to minimize possible image deterioration.

True Wide Dynamic Range

True Wide Dynamic Range (True WDR) is a sensor-based technology that can produce images with an extremely wide dynamic range. Image sensor of a True Wide Dynamic Range Security Camera can capture several images with short and long exposures, then combining them into a single frame. True WDR in a True Wide Dynamic Range Security Camera can be adjusted using three pre-set levels (Low/Mid/High) according to the lighting conditions. Proper calibration of WDR level is essential to achieving the best result – setting the WDR level too low may not produce satisfying visibility, while setting the Wide Dynamic Range level to high may lead to washed out images.


How to choose the best WDR Security Camera?

Wide Dynamic Range can vary from a low of 60dB to a high of 130dB in the best-performing IP Security Cameras on the market. A Wide Dynamic Range Security Camera with a 60 dB dynamic range would do a good job of clearly recording a scene with low or high light levels, however, most Wide Dynamic Range Security Camera are not rated at that high of a level. Wide Dynamic Range is a key specification on security cameras when it reaches greater than 100dB.
