Solar external 2-beam infrared barrier

Wireless solar infrared barrier in a small, discreet housing, designed for perimeter protection of buildings. It is used in the protection of entrance gates, traffic control zones and industrial fences. It triggers an alarm only when all the detector beams are interrupted at the same time, thanks to which it reduces the occurrence of "false alarms". The source of energy acquisition are modern photovoltaic panels that charge the battery built into the receiver and transmitter (it is possible to power from the mains power supply), tamper alarm, easy configuration ? button to change the operating/off mode.
