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

A video doorbell is a smart security device that replaces or supplements your traditional doorbell. It includes a built-in high-definition camera, microphone, speaker, and often motion sensors, allowing homeowners or business owners to see, hear, and speak to visitors at their door — all through their smartphone.

Key Components of a Video Doorbell:

Component	Function
Camera	Captures live or recorded video of the entryway
Microphone	Picks up audio from outside
Speaker	Allows two-way communication with visitors
Motion Sensor	Detects movement and triggers alerts or recordings
Wi-Fi Module	Connects the doorbell camera to your home or business network
Mobile App	Enables viewing, alerts, and interaction directly on a smartphone

How It Works:

1. Visitor Presses the Doorbell
   The system sends a push notification to your phone via an app.
2. Motion is Detected
   Even if the button isn’t pressed, motion sensors trigger a live view or recording.
3. Live Video Stream
   You can watch a real-time video feed of the visitor using your phone.
4. Two-Way Audio
   Speak to the visitor remotely through your phone.
5. Cloud or Local Storage
   Videos are often saved for later viewing, either locally (SD card) or in the cloud.

Applications:

• Residential Homes: Enhance security and convenience
• Apartments: Provide remote access without needing to be physically present
• Businesses: Monitor deliveries, customers, and employees through remote access
