Abstract
A system, method and apparatus for monitoring a barrier. The barrier sensor refrains from transmitting an alarm signal to a receiver when the barrier sensor determines that the barrier has been placed into an open position and that a human being is inside the premises in proximity to the human detection device. Further, the barrier sensor transmits an alarm signal to a receiver when the barrier sensor determines that the barrier has been moved from the open position and that a human being is not inside the premises in proximity to the barrier.
