Wide-area Infrared System for Persistent Surveillance (WISP)

Organization: MIT Lincoln Laboratory
Year: 2017

The portable Wide-area Infrared System for Persistent Surveillance (WISP) sensor system detects all moving objects at long range in the ground or air, and marks the objects on a continuously updating real-time display. The display WISP creates is a high-resolution, black-and-white image. Moving objects are highlighted with colored boxes, and direction vectors can be shown with colored lines. The 400 megapixel, 16-bit display is a long-wave infrared (LWIR) thermal image that covers more than a full hemisphere around WISP’s location. The display is refreshed every second, and a user-friendly graphical interface allows an operator to zoom in on moving objects of interest for a closer look. Because WISP features an LWIR detector, it can function equally well in the day or night because it passively detects thermal radiation. The WISP system exports data to a wide-area network that allows multiple users to access the data in real-time, anywhere on the network. Data are recorded for 30 days and can be archived, allowing users to review the archive and conduct full forensic investigations.
