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

A video doorbell is a smart home device that combines the functionality of a traditional doorbell with a built-in camera, microphone, speaker, and WiFi connectivity. It allows users to see, hear, and speak with visitors at their door through a smartphone app — even when they are not at home.

Key Components of a Video Doorbell:

Component	Function
Camera	Captures real-time video of the visitor at the door
Microphone/Speaker	Enables two-way audio communication
Motion Sensor	Detects movement and sends alerts to the user’s phone
WiFi Module	Connects the doorbell to the internet and links it to a mobile app
Storage	Cloud or local storage for video recordings
Power Supply	Battery-powered or hardwired to existing doorbell wiring

How It Works:

1. Detection: The motion sensor or doorbell press triggers the camera.
2. Notification: A real-time push notification is sent to the paired mobile app.
3. Live View: Users can view the video feed and start two-way communication.
4. Recording: Video footage is often saved to cloud or local storage for review.

Mobile App Integration:

Most video doorbells pair with a dedicated mobile app that supports:

• Live video streaming
• Motion detection alerts
• Two-way audio
• Cloud storage access
• Smart integrations (Google Assistant, Alexa)

2. Choose your doorbell brand and follow the linking instructions.
3. Enable the corresponding Alexa Skill (e.g., “Ring,” “EufySecurity”).
4. Log in with your doorbell account credentials.
5. Discover devices → Your doorbell appears under “Cameras”.

For Google Home:

1. Open the Google Home App → Tap “+” to add a new device.
2. Select “Set up device” → “Works with Google”.
3. Search for your doorbell brand → Link the account.

3. How to Set Up Motion Detection on a Video Doorbell

Motion detection is one of the most valuable features of a video doorbell. It allows users to receive alerts when someone approaches the door, even if they don’t ring the bell — boosting security and awareness.

Benefits of Motion Detection:

• Prevention: Deter package theft or suspicious activity.
• Automation: Trigger lights or alarms when motion is detected.
• Recording efficiency: Record only when activity is detected to save storage.

Setup Process (Varies by App):

1. Download the App: Use the OEM-provided or branded app.
2. Pair the Doorbell: Connect the doorbell to your app via WiFi.
3. Navigate to Settings → Motion Detection:
   • Enable motion detection
   • Adjust detection zones (exclude street traffic, etc.)
   • Set sensitivity (low, medium, high)
   • Configure notification preferences (app alerts, email, etc.)

Motion Detection Table:

Feature	Description	Option Range
Sensitivity Adjustment	Determines how easily motion is detected	Low / Med / High
Motion Zones	Define specific areas where motion should trigger alerts	Customizable Zones
Smart Detection (AI-based)	Differentiates between people, animals, vehicles	Available in AI models
Alert Frequency	Control how often you get alerts	Once per min / Instant
Notification Type	Push, email, in-app alert, or all	Configurable

4. Do Video Doorbells Record All the Time?

Whether a video doorbell records continuously or only when motion is detected depends on the model, storage capability, and user preferences.

Recording Modes:

Mode	Description	Suitable For
Motion-Triggered	Records only when movement is detected	Standard home use
Continuous Recording (24/7)	Records 24/7 footage regardless of activity	Business / High-security
Event-Based Clips	Short clips around events (e.g., doorbell press)	General users

Storage Options:

• Cloud Storage: Subscription-based, video stored on manufacturer’s servers
• Local Storage: Via microSD cards or Network Video Recorders (NVRs)
• Hybrid Systems: Offer both local and cloud backups

🔐 Buyer Note: For B2B applications, such as apartment complexes or office buildings, continuous recording may be necessary. FARHD’s OEM solutions support customizable storage options, enabling integration with enterprise-grade NVRs or cloud servers.
