The Protech 30840111 SOLARIS 6.5 ft (2 m) Single Face TX Tower delivers intelligent, solar-powered perimeter protection as part of the revolutionary SOLARIS wireless infrared barrier system. This transmitter tower features 5 infrared cells providing enhanced detection density across the 6.5-foot height, creating a robust beam curtain that reliably detects intrusion attempts up to 328 feet (100 m) from its paired RX receiver. Equipped with an integrated Connect board, the tower communicates via a dynamic 915 MHz LoRa mesh radio network with 128-bit AES encryption - eliminating the need for hardwired connections between towers. The onboard solar panel and battery provide fully autonomous operation, while anti-condensation caps protect the optical cells in humid environments. Built-in audible and visual alignment aids simplify installation, and comprehensive alarm reporting includes intrusion, disqualification, tamper, power failure, low battery, and loss of radio link - all transmitted wirelessly to the SOLARIS Radio Coordinator for seamless integration with your security management system.
