NFL officials took great effort in making sure the 80,000 fans were safe at the Super Bowl 48 Sunday in New Jersey. And a Minnesota company played a big role in keeping everyone safe. Twenty security cameras were strategically placed at the MET Life Stadium’s parking lot, surroundings, and nearby hotels to help keep deter crime and terrorism.

Thanks to Steve Dunker of Mobile Pro System based out of West Saint Paul whose company made mobile trailer units that power the cameras atop thirty foot masts. The trailers use generators, solar panels, and even wind to power cameras, lights, and radar for months. This technology is also used at construction sites, mines, and by the U.S. Navy. Separately, Mobile Pro Systems also says the University of Minnesota is evaluating whether the systems might also prevent or reduce crime on campus.
