With surveillance cameras at most big facilities, such as airports, guards monitor multiple screens. And if they zoom, they lose image resolution, along with perspective on the surrounding area. The Imaging System for Immersive Surveillance (ISIS) solves these problems by combining nine video cameras in one device. Mounted to a ceiling, ISIS offers 360-degree, 100-megapixel views on a single screen. Image-stitching software merges multiple video feeds into one scene. The system also allows operators to tag and follow targets, and can monitor restricted areas and sound an alert when intruders breach them. Watch for ISIS (it will be watching for you) at Boston’s Logan International Airport, where the system debuted last December.
