A solar-powered wireless infrared break beam sensor that is easy to install and requires no wiring. The break beam sensors are powered by built-in lithium-ion batteries that are recharged through the solar panels during the day. Installation time can be as little as a few minutes. The infrared sensing terminals can be mounted up to 300 feet apart and will send a signal back to the receiver up to about one mile away anytime someone passes between the sensors.
The break beam sensor is a point-to-point sensor and is not activated by any motion outside of the monitored beam. It is not affected by small objects such as falling leaves or birds. It can be mounted high enough to avoid dogs and other animals but will detect any intruder walking through the beam area. The beam sensor is ideal for outdoor applications such as storage lots, lumber yards, and car dealerships. Multiple sensor pairs can be used to send a signal to one receiver if you wish to set up a perimeter.
