Step-by-step fix guide | eufy Video Doorbell S4

Try this first — Tap Retry to refresh the live feed, and check whether your recorded videos still play. They’re the first checks in eufy’s live video guide for its wired doorbells.

This guide is for owners of the eufy Video Doorbell S4 whose live view won’t load. eufy doesn’t yet have an S4-specific article for this fault, so the steps below come from eufy’s guide to live video on its wired doorbells, which covers eufy’s wired doorbells in general. Where the S4’s own pages give a different figure, we use the S4 figure.

What This Problem Means

The live stream isn’t reaching your phone, even though the doorbell can still be recording. eufy’s checks cover the app, the doorbell’s power, your router and your phone’s connection.

Common Symptoms

  • Live view keeps loading or fails
  • Recorded clips play, but live view doesn’t
  • Live view works on one phone but not another

Safe Checks You Can Try

1. Check recorded videos and tap Retry

eufy says to check whether you can view historical videos, and to press the Retry button to refresh the live feed.

2. Log out and back in

Log out of your eufy account in the app and log in again, then try live view.

3. Check the doorbell has enough power

eufy says to upgrade the transformer if it doesn’t meet the doorbell’s requirements.

eufy’s S4 user guide asks for a 16-24V AC, 10-40 VA transformer, and says an underpowered transformer may overheat, burn out or make the doorbell malfunction. If you’re not sure your transformer is up to it, have an electrician check it.

4. Check your router settings and distance

eufy says to check whether your router has access control or firewall settings that block the doorbell, and to keep the router within about 9 m (30 ft) of the doorbell.

5. Check your phone’s connection

Try mobile data instead of Wi-Fi, turn off any VPN, try another phone, and make sure Low Data Mode is turned off on your phone. eufy’s last resort is to reset your phone’s network settings and restart it.

6. In other smart home systems

eufy’s Irish S4 landing page says that in third-party ecosystems the S4 supports a fixed live view only, without VR Mode or OmniTrack.

When To Contact Support

If none of these steps fix it, contact eufy through eufy’s support site.
