Active Infrared Break Beam

emitterandreceiver

The IR Break Beam sensor uses active infrared (IR) beams to detect people walking along a trail. The intelligent sensor determines if the passing object is too small or fast to be a human and detects error conditions. It is easy to install and very power efficient. The sensor comes with a 25 foot cable to interface to the Alert Base Station.

The IR emitter portion contains a battery pack which will last for over a year.

The stealthy black probe design – only 0.57″ in diameter maximizes hide-ability. The IR emitter, also a black probe design, has its own battery pack which will last for at least a year. Separate power pack means not having to lay cable underneath a trail.

A second active IR sensor added to your system allows for calculation of speed and direction of travel (in-bound out-bound). In addition, a second IR sensor allows further discrimination of true positives. Triggering one sensor but not the other (perhaps 20 feet away) will not send an alert.
