1. What is a Smart Doorbell with SD Card and How Does It Work?

A smart doorbell with SD card is a video doorbell system that captures and stores video footage directly onto a local microSD card, rather than relying solely on cloud-based storage.

Detección de movimiento	Starts recording only when motion is detected, conserving storage

HD Vídeo	Most support 1080p or higher video resolution
Visión nocturna	Infrared LEDs for recording in low light conditions
Integración limitada o nula con el hogar inteligente	Remote access via mobile apps (iOS/Android)

Cómo funciona:

1. Instalación: Mounts outside the door, typically powered by battery or wired.
2. Setup: Connects to your home or business WiFi network.
3. Grabación: Triggers when someone presses the doorbell or motion is detected.
4. Almacenamiento: Video clips are saved to the internal SD card.
5. Access: Footage can be viewed live or played back via a mobile app or PC.

Why SD Card Matters for B2B Buyers:

• Sin cuotas mensuales: Avoids recurring cloud storage charges.
• Data Sovereignty: Keeps sensitive footage on-premise.
• Escalabilidad: Ideal for multi-unit buildings, offices, and rental properties.

💡Pro Tip: Look for models that support loop recording and SD cards with high write endurance (Class 10 or UHS-I).
