The Core Components:


An intercom system comprises two fundamental components: the base station and substations. The base station is at the entry point and features a call button or keypad for visitor identification. Advanced systems may also include a camera for video communication.


On the other hand, substations are installed within the building, allowing occupants to answer calls, engage in audio or video communication, and potentially control door locks remotely.


The Communication Flow:


Here’s how an intercom system works:


Initiating Contact: When visitors arrive, they press the call button or enter their code at the base station. Some advanced systems may also include facial recognition technology.


Signal Transmission: The signal travels wirelessly through wires or a wireless network to the occupant’s substation.


Alerting the Occupant: An audible ring or visual notification alerts the occupant of an incoming call. Advanced systems may also send notifications to a smartphone or other mobile device.


Two-Way Communication: The occupant answers the call, enabling audio or video conversation with the visitor. During the conversation, the occupant can use intercom features such as call transfer, mute, and volume control.


Optional Door Control: In some systems, the occupant can remotely unlock the door for authorized visitors directly from their substation.


Wired vs. Wireless Intercom Systems


Intercom systems come in two primary configurations: wired and wireless. Wired systems offer reliable communication but require the physical installation of cables throughout the building. Wireless systems provide greater flexibility and ease of installation but may be susceptible to interference.
