What is a Video Intercom and How Does It Work?

A Video-Gegensprechanlagensystems 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
• Wohnanlagen
• Gewerbegebäude und Büros
• Warehouses and industrial facilities

🔧 Key Components of a Video Intercom System:

Komponente	Funktion
Außeneinheit	Installed at the entrance; includes camera, microphone, and call button
Innenmonitor	Allows residents to see and talk to visitors
Stromversorgung	Powers the system (wired or PoE)
Steuereinheit	Manages communication between devices
Wiring or WiFi	Facilitates signal transmission

🧠 So funktioniert es:

• Ein Besucher drückt die Klingeltaste an der Außeneinheit.
• 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.
