Что такое умный домофон и как он работает?

A умный дверной звонок is a Wi-Fi-enabled device installed at the entrance of a building or home. Unlike traditional doorbells, smart doorbells have built-in cameras, microphones, and motion sensors. They allow users to see, hear, and speak with visitors via a smartphone app — even when they’re not home.

Key Components of a Smart Doorbell:

Компонент	Функция
Камера	Captures real-time video of the entrance.
Микрофон/динамик	Обеспечивает двустороннюю аудиосвязь.
Датчик движения	Detects movement near the door and sends alerts.
Модуль Wi-Fi	Connects the doorbell to the home or business network.
Интеграция приложений	Allows remote access through Android/iOS apps.
Облачное хранилище	Stores video footage online (optional, often subscription-based).

Как это работает:

1. Посетитель нажимает кнопку звонка → Notification sent to your smartphone.
2. Motion detected → The sensor triggers an alert and starts recording.
3. Live view → You can watch and communicate with the visitor in real time.
4. Запись видео → Footage can be saved to the cloud or local storage.

Smart doorbells are widely used in both жилой и commercial security applications, такие как:

• Закрытые сообщества
• Многоквартирные дома
• Розничных магазинов
• Office entrances
• Склады

These devices are especially popular in экосистемы умного дома, often integrated with Amazon Alexa, Google Home, или Apple HomeKit.
