The Protech 30840099 SOLARIS 3.3 ft (1 m) Double Face Infrared Barrier delivers fully autonomous, solar-powered perimeter protection with complete wireless connectivity. This compact 3-cell double face configuration provides bi-directional coverage for corner protection and 90° perimeter transitions - all without electrical infrastructure or hardwired data connections. Featuring integrated Connect board technology, each tower communicates alarm data via a secure 915 MHz LoRa mesh network with 128-bit AES encryption to the Radio Coordinator, eliminating trenching and cabling costs. The built-in solar panel and battery ensure continuous operation, while anti-condensation caps maintain optical clarity in humid conditions. With detection range up to 328 feet (100 m), comprehensive alarm outputs (intrusion, disqualification, tamper, anti-climbing, power failure, low battery, loss of radio link), and a wide operating temperature range of -40°F to +158°F, this versatile tower is ideal for remote sites, temporary installations, and rapid deployment scenarios requiring maximum flexibility.
