What is a Video Intercom and How Does It Work?

A système d'interphone vidéo 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
• Complexes d'appartements
• Bâtiments commerciaux et bureaux
• Warehouses and industrial facilities

🔧 Key Components of a Video Intercom System:

Composant	Fonction
ID: Unité extérieure	Installed at the entrance; includes camera, microphone, and call button
Moniteur intérieur	Allows residents to see and talk to visitors
Alimentation électrique	Powers the system (wired or PoE)
Unité de contrôle	Manages communication between devices
Wiring or WiFi	Facilitates signal transmission

🧠 Comment ça marche :

• Le visiteur appuie sur le bouton d’appel de l’unité extérieure.
• 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.
