As an OEM we offer a vast line of telephone entry systems for gated communities, commercial buildings, manufacturing plants, high-end residential homes, and apartments or condominiums.  Our systems are the obvious choice for new construction, but also for renovation replacing century-old intercom technology.  Operating on the existing telephone network, the resident's own telephone becomes an intercom to visitors at the entrance - with the same crispness and clarity of a typical telephone call. We offer a wide range of models and designs to fit your specific requirements.
