VoIP-Telephone for indoor and outdoor applications

With FHF approved technology, the FernTel IP4 is suitable for outside installation. It‘s the ideal weatherproof VoIP desk/wall telephone for applications in potentially harsh and rough environments in many industrial applications -– no matter if exposed to seawater, high humidity or extensive mechanical strain.

The elegant housing is manufactured from polycarbonate: an impact-resistant thermoplastic. The FernTel IP4 provides durability and longevity while minimising the need for maintenance. The FernTel IP4 provides highly effective ergonomics with an intelligent user-friendly menu structure and easy installation and maintenance.

The illuminated keypad and luminous display ensures visability in low light environments. The Ethernet connectivity with the internal 2-port switch allows the user to connect a laptop in an outdoor area which then obtains network access through the telephone. The FernTel IP4 offers high-quality features while meeting industrial standards and provides high quality communication, safely.
