What is a Video Intercom and How Does It Work?

A системы видеодомофона 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
• Жилые комплексы
• Коммерческие здания и офисы
• Warehouses and industrial facilities

🔧 Key Components of a Video Intercom System:

Компонент	Функция
Наружное устройство	Installed at the entrance; includes camera, microphone, and call button
Внутренний монитор	Allows residents to see and talk to visitors
Источник питания	Powers the system (wired or PoE)
Блок управления	Manages communication between devices
Wiring or WiFi	Facilitates signal transmission

🧠 Как это работает:

• Посетитель нажимает кнопку вызова на уличном устройстве.
• 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.
