What is a Video Intercom and How Does It Work?

A sistema de intercomunicación de video is a communication device that allows audio and visual interaction between individuals in separate locations — typically between a visitor at the entrance and a resident inside a building. These systems are commonly used for:

• Residential gate and door security
• Complejos de apartamentos
• Edificios comerciales y oficinas
• Warehouses and industrial facilities

🔧 Key Components of a Video Intercom System:

Componente	Función
Unidad exterior	Installed at the entrance; includes camera, microphone, and call button
Monitor interior	Allows residents to see and talk to visitors
Fuente de alimentación	Powers the system (wired or PoE)
Unidad de control	Manages communication between devices
Wiring or WiFi	Facilitates signal transmission

🧠 Cómo funciona:

• Un visitante presiona el botón de llamada en la unidad exterior.
• The video signal is transmitted to the indoor monitor.
• The resident can view, speak, and optionally unlock the door.

Some systems are standalone and work independently, while others connect to cloud servers for remote access via smartphone apps.
