🏠 What Is a Video Doorbell and How Does It Work?

A campainha de vídeo is a smart home security device that combines a traditional doorbell with a high-definition camera, microphone, and speaker. It enables homeowners and property managers to see, hear, and speak to visitors remotely via a smartphone, tablet, or connected smart home hub—even when they’re not at home.

🔍 How Does a Video Doorbell Work?

Video doorbells work by connecting to your home’s WiFi or wired network and using motion detection to alert you when someone approaches your door. Once triggered, the video doorbell starts recording and sends a notification to your connected device. Some models also allow for two-way audio communication.

Componentes principais:

Componente	Função
Câmera	Captures live video feed of the door area
Captura vídeo ao vivo dos visitantes, geralmente em resolução HD ou Full HD.	Allows you to hear the visitor
Capta áudio do lado do visitante.	Permite a comunicação bidirecional
Sensor de movimento	Captura vídeo de alta definição na porta
WiFi/Network	Connects the device to the internet for remote access and alerts
Integração de aplicativos	Lets you view footage and receive alerts on your smartphone

🔑 Core Features to Expect (Even Without Subscription)

• HD video (720p to 2K resolution)
• Motion detection with real-time alerts
• Comunicação de áudio bidirecional
• Local storage options (SD card, internal memory)
• App control (iOS/Android)
• Visão nocturna
• Wide-angle lens (130°–180° view)

📡 Subscription vs. No Subscription

Many video doorbells offer cloud storage and AI features through paid subscriptions. However, there are top-tier models that offer full functionality without ongoing costs, using local storage or free cloud plans.
