Performance Challenges

Security Camera Performance Challenges

High quality security cameras are better than lower quality cameras in part because they can deliver outstanding image quality in challenging lighting conditions. Two critical technologies that make this possible are true Wide Dynamic Range (WDR) and advanced low-light performance. Combining these two capabilities in a single camera can deliver the best possible images in the most demanding lighting environments, including extreme contrast and low-lighting conditions.

Low Light Operation

In the past, cameras with high-sensitivity imaging chips to capture low-light images delivered grainy, nearly unusable monochrome images. Today, thanks to significant advances in imaging technology, high-quality cameras are capable of capturing clear color images at light levels far below previous minimums. These capabilities extend the range of utility without adding expensive supplemental lighting, and in those cases where lighting is added, it can be kept to a minimal level to conserve energy and reduce any negative impact on neighbors and wildlife.
images that include both light and dark areas; for example, activity in both sunlit and strongly shadowed areas. In the past, cameras had to choose – adjust exposure for the light area to avoid bloom and overexposure, or adjust for the dark areas to enhance visibility. In many cases, the result was to adjust for the overall average lighting – and not optimizing for either the light or dark areas! Today, with more sophisticated imaging sensors, and improved techniques to account for exposure differences, cameras can handle images with a much broader range of light and dark areas, and deliver images with useful information across the full range of lighting.

Ideally, the best choice is cameras that have the ability to simultaneously apply WDR and low-light functionality. In this way, cameras are ready to handle the real world performance challenges that are needed every day.
