Wahsega Labs develops, designs, and manufactures VoIP (Voice over Internet Protocol) products right here in the USA; the metal comes from Tennessee, the stamping work is performed in Wisconsin and the internal circuitry and assembly is completed in Georgia.
The voice communication products they provide are various types of Intercom Systems that can be loaded with features. They are easy to set up after viewing their Training Videos. These Intercom Systems can be used indoors and outside and installed in ceilings and walls, or mounted on freestanding pedestals. The Intercom Speaker systems can also be used for emergency paging and comes with optional door lock relays for classroom safety.
If your searching for a line of Power over Ethernet (PoE) enabled IP Displays that broadcast both audible and visible messages, Wahsega has them. The two-way communication and time synchronization is handled by a network SNTP Server.
