5. Best Practices for Ensuring Stable WiFi Connection for Doorbells

To maintain optimal performance in both residential and commercial installations, follow these best practices for ensuring reliable WiFi connectivity.

1. Place Your Router Strategically

• Install the router as close as possible to the video doorbell.
• Avoid placing it behind thick walls or near large metal objects.
• Elevate the router above floor level for better signal distribution.

2. Use a WiFi Range Extender or Mesh Network

• A WiFi range extender can boost your signal in large homes or offices.
• Consider a mesh WiFi network for seamless coverage across multiple rooms or buildings.

3. Limit Network Interference

• Keep other wireless devices (e.g., baby monitors, microwaves) away from the doorbell.
• Avoid overlapping WiFi channels by setting your router to auto-select or manually choosing a less crowded channel.

4. Optimize Internet Bandwidth

• Prioritize smart security devices using Quality of Service (QoS) settings on your router.
• Disconnect unused devices from the network to reduce congestion.

5. Secure Your WiFi Network

• Use WPA2 or WPA3 encryption para impedir o acesso não autorizado.
• Update your WiFi password regularly.
• Change the default router admin credentials.

6. Regularly Update Firmware

• Smart doorbell manufacturers often release firmware updates to improve connectivity and security.
• Ative automatic updates in the app if supported.
