One of the most rapidly changing aspects of video surveillance today is the improved performance of low-light cameras, which have made tremendous strides in leaving behind the bad memories of poor performance that pervaded the space just a few years ago.
In the early days, cameras’ low-light video typically consisted of monochrome or black-and-white video, supplemented by external white or IR lighting. This severely limited the visual data that could be pulled from it and reduced video to flat imagery, says Jeff Whitney, vice president of marketing, Arecont Vision Costar, Glendale, Calif.
