Dakota Alert 2500 Wireless Break Beam Sensor Kit

Solar powered wireless infrared break beam system that is simple to install and requires no wiring. Break beam sensors are powered by lithium ion batteries that are recharged through the solar panels during the day. Infrared sensing terminals can be mounted up to 300 feet apart and will send a signal back to the DCR-2500 receiver up to half mile away anytime someone passes between the sensors. Will not be activated by any motion outside of the monitored beam. Sensors are not affected by small objects such as falling leaves or birds. Ideal for outdoor applications.
