Step-by-Step Setup Guide for eufy Security Video Doorbell C31 T8223

Charge the battery fully before installation or confirm that the wired transformer meets the required voltage range.
Download the eufy Security app and create or sign in to your account.
Power on the doorbell and scan the QR code in the app to begin pairing.
Select either battery setup or wired setup, then follow the on-screen prompts to connect to 2.4 GHz Wi-Fi.
Mount the bracket at chest height for better face capture and test the viewing angle before final tightening.
If using hardwired mode for 24/7 recording, verify that the transformer and wiring support the required configuration and follow the bypass instructions for the existing chime if prompted.
Enable motion zones, notification settings, and optional HomeBase 3 or Alexa/Google Assistant integration.

If pairing fails, move closer to the router, restart the app, and confirm that your phone is connected to a stable 2.4 GHz network.
