The EMX USS-1 (Unattended Surveillance System) combines several technologies to provide a cost-effective surveillance solution. The USS-1, dubbed "Black Wolf" is a two-wheeled trailer with day/night sensor package, wireless control, 27-foot collapsing mast, solar panels and batteries. It is designed to operate as long as one week, with no sunlight. The Black Wolf can be set up in less than 30 minutes and is designed to work as a "Wolf Pack" of up to four trailers that can be arranged as the user sees fit. Operating completely unattended and self-powered, the four trailers are able to control an area 20 kilometers long by 5 kilometers wide if they are daisy-chained in a linear array.
