Building Protection Systems, Inc.'s Mobile Sentry One is based on the same technology as the company's Building Sentry Oney. Mounted inside a lightweight 4 foot wide by 6 foot long by 5 foot high trailer, the rugged, shock resistant Mobile Sentry One system can be transported anywhere it can roll. The 120v hook-up allows for unlimited detection run time while the onboard battery power supply provides up to four hours of back-up operation. Optional solar and generator power supplies are also available. Each Mobile Sentry One trailer can be easily networked to other Mobile Sentry One trailers, providing complete perimeter protection from an airborne release or targeted attack.
