What is Intercom System?
An intercom, short for intercommunication device, is a stand-alone voice communications system used within a building or a small collection of buildings. Intercoms are independent from the public telephone network and have a range of applications, from simple door entry systems to complex multi-unit systems used in larger buildings.

Types of Intercom Systems
Wireless Intercoms
Wireless intercom systems are ideal for applications where wiring is impractical or impossible. These systems include a range of two-way communication devices such as handheld radios, outdoor wireless callboxes, and traditional desktop units. The transmission range of these units varies widely depending on the technology used. For example, two-way radio intercoms can transmit up to a mile, and their range can be extended with external antennas. Operating on UHF and VHF frequencies, these systems provide long-range communication and can integrate with existing two-way radios.
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
While not traditional intercoms, two-way radios can communicate with base station intercoms. This setup combines the mobility of two-way radios with the comprehensive capabilities of fixed intercom systems, providing versatile long-distance communication.
Understanding What Intercom Systems are All About
Wired intercom systems
Wired intercom systems are some of the most common intercoms around and date back to around the 1980’s. The audio signals are transmitted via 2-wire shielded or Cat-5/6 wires and are as reliable as they come. You don’t have to worry about other devices interfering with your communications because it transmits signals through an analogue connection. The message will remain clear and consistent each time you use it and you’ll enjoy better privacy between you and the person you’re talking to.
01
Wireless intercom systems
Wireless intercom systems have superseded wired intercoms for two reasons. One is because it’s easier to install and two, you don’t have to deal with wires of any kind. Handheld radios and outdoor wireless call boxes are just some examples of devices used in wireless intercom systems.
02
Video intercoms
Video intercoms feature a unit with a speaker and a camera for video transmissions. It’s a stand-alone intercom system that’s used to manage calls made at a building entrance for security purposes. The access is controlled by audiovisual communication between the person on the outside and the person on the inside. This enables the person indoors to verify the identity of the visitor prior to granting entry on the front door.
03
Two-way radios
While two-way radios aren’t classified as intercoms, they are capable of communicating with base station intercoms. What this does is give you the flexibility of a fixed intercom along with a mobile radio that can communicate over long distances.
04
Apartment intercoms
Apartment intercoms are quite similar to video intercoms in a way that they use video transmissions for communication. Each apartment/flat is equipped with a unit that enables the person inside to see who their visitors are. Once they’ve confirmed the person’s identity, they can proceed to open the door just by pushing a button.
05
Home Intercom Components
A home intercom system is made up of several components including a base station, which is the central control point of the home intercom system. This can be a physical device or a smart app accessible via a smart device and stored in the cloud. Other components include the intercom stations which contain a camera and microphone to allow for two-way communication. This is the part of the intercom that is usually placed outside your front door, gate or whenever you receive your visitors. Another intercom station may be placed inside your home so that you can communicate with any visitors and allow them access to your home, however some systems now allow you to do this from your smart device allowing for total remote management of your home intercom and visitors.
Home Intercom System Communication
To hear or see the visitor on the other side of the door, the intercom stations will transmit the voice and/or video image data via wires or wirelessly (over a wifi connection) via the base station, to the other receiving intercom station.
Locking System Integration
If your home intercom system is integrated with your locking mechanism system, then you will have the ability to open gates and doors for your visitors from the push of a button or a tap on a smart device. This works by triggering an electronic relay inside of the intercom at your home’s entrance, which sends a signal to the door or gate releasing mechanism, thus unlocking the entryway.
Benefits of Intercom Systems
Enhancing Security
Intercom systems are instrumental in enhancing security measures. Whether it’s a gated community, office building, or educational institution, intercoms provide a controlled and monitored access point.
Improved Communication
Intercom systems facilitate seamless communication within buildings and properties. Occupants can effortlessly communicate with one another, whether it’s between different units in an apartment building or across different departments in an office complex.
Convenience and Efficiency
Intercom systems streamline various operations, making daily tasks more convenient and efficient. In residential settings, intercoms enable residents to communicate with delivery personnel, granting access for package drop-offs even when they are not at home.
Emergency Communication
During emergency situations, quick and effective communication can be a matter of life and death. Intercom systems excel in emergency scenarios by providing a reliable communication channel for immediate response and coordination.
Integration with Security Systems
Intercom systems can integrate with other security systems, enhancing their capabilities. Integration with video surveillance allows users to view live video feeds and communicate with individuals on the premises, verifying their identity before granting access.
Visitor Management
Intercom systems simplify visitor management processes. Through audio and video communication, occupants can remotely verify visitors’ identities, granting or denying access as needed.
Installation of Intercom Systems
The first step in installing an intercom system is planning and design. This involves determining the locations of intercom units, the type of system to be used, and any additional features required. For wired systems, this also includes planning the wiring routes.
For wired intercom systems, the next step is running the necessary wiring. This often involves drilling holes and running cables through walls and ceilings. It’s important to follow building codes and regulations during this process.
Once the wiring is in place (for wired systems), the next step is mounting the intercom units. This involves physically attaching the intercoms to walls or other surfaces and connecting them to the wiring or wireless network.
After installation, the system needs to be configured and tested. This includes setting up any necessary software, configuring settings, and testing the communication between units to ensure everything is working correctly.
Finally, users should be trained on how to use the system, and a maintenance plan should be established. Regular maintenance can help ensure the system continues to function properly and can extend its lifespan.
Components of Intercom Systems
Whether wired or wireless, the main components of an intercom system consist of the control panel, or master station, and substations with speakers.
The master station is the control panel. It contains the electronic circuitry for the intercom system. It may include the power switch for the entire system, as well as radio or other music distribution controls.
Some basic systems only allow you to talk from a substation to the master station, rather than from substation to substation. Keep this limitation in mind when you are shopping for a system.
Substations, also called remote stations, consist of a speaker, which can deliver audio and act as a microphone during a reply, and a switch to transfer from listen to talk modes.
Check the range on wireless substations if you’re planning to install one in an outbuilding or at a gated entry. The range of wired substations is limited only by how far you are willing and able to run the wires connecting it.
Outside substations, often installed at an entry door and with a doorbell, allow you to know who is ringing the bell without having to open the door.
More complex intercom systems allow you to talk from substation to substation, rather than having to go through the master station, and offer a privacy setting, which turns off a substation at the substation itself, rather than only at the master station.
Intercom systems for homes can let you easily talk to people in other rooms of your house. They can also add to your home’s security, especially if you opt for a video intercom or smart doorbell that lets you hear and see who is outside your house.
