6. How to Use a Smart Doorbell with Alexa or Google Home

For consumers and smart home integrators, seamless integration with voice assistants is a major selling point. Let’s explore how to set up and use video doorbells with Alexa and Google Home.

Alexa Integration

Most modern smart doorbells are compatible with Amazon Alexa. Here’s how to set it up:

1. Install the Native App: Set up your doorbell using the manufacturer’s app.
2. Enable the Skill: Open Alexa app → Skills & Games → Search for your doorbell brand → Enable it.
3. Link Account: Log in to your doorbell account to authorize Alexa.
4. Discover Devices: Alexa will automatically detect and add your doorbell.
5. Use Commands:
   • “Alexa, show the front door.”
   • “Alexa, talk to the visitor at the front door.”

Google Home Integration

Similar to Alexa, Google Home allows you to control and view your doorbell feed.

1. Open Google Home App.
2. Tap ‘+’ to Add Device.
3. Choose ‘Works with Google’ and search for your doorbell.
4. Log in and Authorize.
5. Use Voice Commands:
   • “Hey Google, show me the front door.”
   • “Hey Google, talk to the front door.”

B2B Relevance

If you’re a video doorbell OEM supplier, make sure your product supports:

• RTSP or WebRTC protocols
• API/SDK for third-party integrations
• Dual-platform compatibility (Alexa & Google)

This is particularly important for distributors targeting markets in North America and Europe, where voice assistant usage is high.

Pro Tip: When sourcing from manufacturers like FARHD, you can request firmware integrations preloaded to optimize compatibility with smart ecosystems.
