Hear, be heard and understood in any Environment

By developing revolutionary IP-based Intercom and PA solutions, we deliver clear, intelligible audio in highly noisy environments over standard power over Ethernet connections.
We provide audio solutions that seamlessly integrate into other commonly used technologies so a virtual presence can be achieved.

With 70 years in the communications market, what separates Zenitel from the rest of the intercom providers is our specialty – Critical Communications over IP (CCoIP). With features and functions so advanced, our systems have been implemented and proven in the most demanding of environments.

Whether you are adding to a security system or your VOIP or SIP phone system Stentofon makes integration with these systems easy!!!  Many integrations with access control and video surveillance software exist today so be sure and check with your favorite manufacturer.  Stentofon makes their SDK availability open to the security and technology community so please ask us how to acquire should you have the need.
