Wide Dynamic Range Cameras

Posted by on

A relatively recent security technology for video surveillance has revolutionized the way surveillance solutions address areas with extreme back light and glare conditions. These areas can be found in almost any facility that have glass entry ways, entrance doors with East or West orientations, large numbers of electronic devices that emit varying colors and light intensities, and outdoor venues. This technology is referred to as Wide Dynamic Range. The enhancements are extraordinary with relation to how images are processed when deployed in these challenging light environments that normally create havoc for traditional surveillance cameras.

Typical cameras have a very difficult time capturing images that have a lot of light variation, or more specifically, a great deal of back light. Two of the examples in the images below illustrate the way difficult lighting conditions are processed by traditional surveillance cameras (left image is from a standard camera and center image is from a standard camera using back light compensation). These images are compared side by side with the image processed by our wide dynamic range cameras.

Wide Dynamic Range Camera Image Comparison An image is divided into small segments called pixels. Most cameras calculate light intensity for the entire image (average across all pixels). The above images have a lot of light from the outside shining behind dark objects (people at the table, the table itself, and the window frames). When the camera receives a large amount of light resulting from the sun in the background, it concludes that the image area averages to be very bright and closes down the iris (resulting in the blackening out of the darker objects as shown in the left image above). Back light compensation cameras (center image above) consider the extreme back light intensity and attempt to focus on the darker objects and white out the bright background.

Orion Security Solutions' wide dynamic range cameras are the ideal solution for the issues described above so that our customers are able to effectively resolve problems related to challenging lighting environments. Wide dynamic range cameras are able to calculate the light intensity in each pixel individually and, through analytic intelligence, compensate for the extreme variations across the image so that pixels with large amounts of light can be dimmed and those that are dark can be brightened. The result is a clear image that can focus on the dark near field and the bright far field simultaneously, even with such an extreme lighting contrast.

Orion Security Solutions continues to be the customer's choice when it comes to specifying and applying the proper security technology solutions for any type of environment. We appreciate the expertise we have acquired through years of deploying and integrating advanced security technologies and solutions around the world. Our global experience operating in critical environments such as US Embassies and protecting national security and classified information is what distinguishes us from all other competitors and what gives our customers the peace of mind they deserve. We look forward to sharing our knowledge and insight with you.

Sean Crain is founder and CEO of Orion Security Solutions (OSS). Prior to starting OSS, Sean spent over eight years with the U.S. Department of State as a Diplomatic Security Service (DSS) Officer working in nearly 40 countries on 6 continents around the world including Thailand, Vietnam, Burma, Switzerland, Indonesia, Australia, Cambodia, Austria, Germany, Poland, Kenya, Uganda, Egypt, Brazil, Peru, and Columbia.



He received advanced training in the techniques and methodologies of counter intelligence and anti-terrorism in order to carry out responsibilities which included designing, installing, and maintaining state-of-the-art security solutions to protect national security information, U.S Embassies and other sensitive U.S. facilities, and diplomatic personnel, including U.S. Presidents and Secretaries of State. Sean was also called upon to design and implement security protocols and systems which included video surveillance, intruder detection, access controls, locks, perimeter security, and assessments. He also played an integral role in writing the U.S. Department of State security policies for post communications centers, controlled access areas, and building management systems in U.S. Embassies, U.S. Consulates, and inter-agency facilities worldwide.
