Core Components of a Wireless Intercom System

While wireless intercoms eliminate the need for physical cables, they still include several essential components that work together to enable seamless communication.

1. Master Station (Indoor Monitor)

This is the central unit typically located inside the building. It allows users to:

• Initiate or receive calls
• Unlock the entrance remotely
• View video feeds (if supported)
• Communicate with outdoor stations or other indoor units

2. Outdoor Station (Doorbell Unit)

Installed at entry points like gates or doors, this unit features:

• Microphone & speaker
• Camera (for video intercoms)
• Call button
• Night vision (optional)

3. Power Supply

Wireless intercom systems usually require a power source:

• Funciona con pilas (rechargeable or replaceable)
• AC-powered (via power adapter)
• PoE (Power over Ethernet) – for hybrid wired-wireless systems

4. Connectivity Module

This is the heart of the “wireless” feature. It manages communication using:

• WiFi
• Radio Frequency (RF)
• Bluetooth
• DECT (Digital Enhanced Cordless Telecommunications)
• Cellular (4G/5G) or LAN networks

5. Mobile App or Cloud Platform (Optional)

Modern wireless intercoms offer remote access via smartphone apps, allowing users to:

• Receive notifications
• See real-time video
• Unlock doors remotely
• Review video history (cloud or local storage)

How Wireless Intercom Systems Work: Step-by-Step Process

Understanding the workflow helps both end-users and B2B buyers assess system performance and integration potential.

Step 1: Visitor Initiates Contact

The visitor presses the call button on the unidad exterior, which sends a signal to the monitor interior (or multiple monitors in the case of multi-room systems).

Step 2: Instant Transmission

The system uses wireless protocols (e.g., WiFi, RF) to transmit the signal. If it supports video, the camera activates and sends a live feed to the indoor monitor or mobile app.

Step 3: Real-Time Communication

The resident or employee answers the call, initiating comunicación bidireccional through built-in microphones and speakers.

Step 4: Remote Access Control

If the system supports it, the user can remotely unlock the door or gate via:

• A button on the indoor monitor
• A smartphone app
• Voice command (if integrated with Alexa, Google Assistant)

Step 5: Optional Recording or Cloud Storage

Advanced intercoms can record video or audio and store the data locally (SD card) or in the cloud, enhancing security.
