An intercom system is a two-way electronic communication device designed for transmitting and receiving audio and/or video transmissions. With the advent of cellular communication, digital telephone systems, and other innovative communication technologies, modern intercom systems have evolved to integrate these advancements.
Types of Intercom Systems
Intercom systems come in a variety of types, each designed to cater to specific needs and environments. Here’s an overview of the most common intercom systems:
Wireless Intercoms
Wireless intercom systems prove beneficial for situations where installing wires is not feasible. The wireless intercom systems feature multiple forms of two-way communication equipment which include handheld radios together with outdoor wireless callboxes as well as conventional desktop models. The technology behind these units determines the extent of their transmission range. Two-way radio intercoms transmit signals up to a one-mile distance which can be extended further by attaching external antennas. Systems that work on UHF and VHF frequencies deliver long-distance communication capabilities while supporting integration with current two-way radio systems.
Wi-Fi intercom systems for doors, gates and apartments enable wireless communication throughout the Wi-Fi network's coverage area. The cell phone intercoms work as wireless intercoms capable of reaching virtually unlimited distances by using cellular service where they are installed.
License-free MURS base stations represent advanced wireless intercom systems which deliver functions beyond simple communication. These systems enable broadcasting to multiple stations while also linking to amplified wireless PA units. Outdoor wireless callboxes enable two-way conversations and customer service callboxes provide pre-recorded messages activation through button pressing.

Wired Intercom Systems
When wiring between locations is feasible, wired intercom systems provide enhanced privacy and eliminate potential interference from neighboring wireless systems. These systems can use various wire types, including 2-wire shielded cables or CAT-5/6 cables. CAT-5 intercoms are commonly used for door or gate applications. Wired units are often preferred for video intercom systems due to the challenges of transmitting large amounts of video data wirelessly. Our 10-Call Master System enables communication between multiple substations and a master station. Additionally, VoIP intercoms, using Ethernet wiring, offer superior audio quality and can integrate with existing VoIP telephone systems.
Video Intercoms
Video intercom systems typically feature an entrance unit with a camera, speaker, and push button, and an internal monitor unit. These systems allow users to see and communicate with visitors at the entrance. Most video intercoms are wired to ensure reliable video transmission over long distances. However, some multi-tenant intercoms use Wi-Fi connectivity to facilitate communication within apartments. We also offer a CAT-5 video system that can be converted to wireless using networking equipment.
Apartment Intercoms
Apartment intercom systems consist of a door unit at the entrance and individual units within each apartment. These systems enable tenants to communicate with visitors and grant access. Basic systems are wired, allowing tenants to use a wired station to talk to visitors and unlock the door. Advanced systems use cellular technology to provide the same functionality via mobile or landline phones, even when tenants are not home. Cutting-edge cloud-based systems offer features like video, QR code entry, and integration with voice assistants such as Amazon Alexa or Apple Siri.Two-Way Radio Intercoms
