1. What is a video doorbell with battery and SD card?

A video doorbell with battery and SD card is a smart security device designed to be installed at your front door, allowing you to see, hear, and speak to visitors via a camera and microphone — all without the need for hardwiring.

• Módulo da câmera: Captures HD video, often with wide-angle and night vision.
• Motion Detector: Triggers video recording when movement is detected.
• Áudio bidirecional: Enables communication with visitors from your smartphone or monitor.
• Conectividade WiFi: Connects to your home network for real-time notifications and live viewing.

Porque é que é importante para os compradores B2B:

Wholesale buyers, real estate developers, and smart home system integrators prefer these models because they:

• Reduce installation costs (no wiring required)
• Offer storage independence (no cloud fees)
• Improve user privacy (local data storage)
• Enable easy scalability for large property projects or rentals
