1. What Is a Video Doorbell and How Does It Work?

A видеозвонок is a smart home security device that replaces or enhances your traditional doorbell by adding a video camera, microphone, speaker, and Wi-Fi connectivity. It allows homeowners and businesses to see and communicate with visitors at their door through a smartphone or monitor, even from remote locations.

Как это работает

• Обнаружение движения: Detects motion near your door and starts recording or sends alerts.
• Двухстороннее аудио: Lets you talk to visitors through your phone or intercom system.
• Просмотр в реальном времени: Stream real-time video from the doorbell camera.
• Облачное или локальное хранилище: Stores video footage either on the cloud or locally via SD card or NVR system.

Умные дверные звонки с локальное хранилище have gained popularity due to privacy concerns and subscription-free video access.
