Intercoms are audio communication systems that use fixed-location terminals with speakers, microphones, and cameras that allow people to communicate with other connected intercom stations. Audio intercom stations and kits are the primary components that provide audio communications in an intercom system. Video intercom stations and kits allow users to communicate with remote locations using audio and video. Intercom microphones, keypads, and displays integrate with existing intercom systems to add new functions or replace damaged parts. Mounts, boxes, and housings for intercom stations provide stable mounting locations for intercom systems and protect their electronics. Controls and power equipment for intercoms connect the parts of an intercom system and provide them with power to operate.
