Quick Answer: Most eufy cameras — eufyCam models, SoloCam models, and Indoor Cams — factory reset the same way: hold the SYNC button for 8-10 seconds until you hear a beep (two beeps on SoloCam and Indoor Cam models), per eufy’s own support documentation. You can also reset any online camera from the eufy Security app (Settings → Remove Device). The one risk unique to eufy in this series: a HomeBase factory reset — not just a camera reset — erases every local recording stored on it, since local storage is eufy’s whole selling point. Cloud-first brands like Ring or Arlo don’t have this exposure, because their recordings never lived on hardware you own in the first place.

eufy is the 6th brand in our reset-guide series, joining Ring, Nest, Blink, Arlo, and Wyze. It’s also the first brand in the cluster where the bigger risk isn’t a fumbled reset button — it’s resetting the wrong device entirely.

Factory reset a eufyCam (HomeBase-dependent)

Covers the eufyCam S3 Pro and other eufyCam-series add-on cameras that pair to a HomeBase for local storage and power management.

  1. Find the SYNC button on the camera body — usually on the top or side, depending on the model.
  2. Press and hold for 10 seconds, per eufy’s support documentation. A beep confirms the reset.
  3. Re-add the camera through the eufy Security app, pairing it to the HomeBase again as if new.

eufyCam S3 Pro

Current best-overall eufy pick, HomeBase-paired · 4K, solar-capable, no monthly fee
  • 4K video with free on-device AI detection and up to 365-day battery life on a single charge.
  • Same 10-second SYNC-button reset as the rest of the HomeBase-dependent lineup — no special quirks.
  • Worth considering as a straightforward add-on if a reset doesn't bring an aging eufyCam back.

Factory reset a standalone eufy SoloCam

Covers the SoloCam S340, SoloCam S40, and similar models that connect straight to Wi-Fi with no HomeBase required.

  1. Find the SYNC button on the back of the camera.
  2. Press and hold for about 8 seconds until you hear two beeps, per eufy’s support documentation.
  3. Set the camera up again in the eufy Security app as a new device, rejoining it to Wi-Fi from scratch.

SoloCam S340

Best standalone eufy pick, no hub required · self-charging solar panel
  • Local storage built into the camera itself — no HomeBase to lose recordings from if the camera is reset.
  • 8-second SYNC-button hold, two-beep confirmation, distinct from the 10-second single-beep eufyCam process.

Reset a eufy camera from the app (no button needed)

Works for any camera that’s currently online — useful when the physical button is hard to reach.

  1. Open the eufy Security app and select the camera.
  2. Tap the settings (gear) icon, then Remove Device, and confirm.
  3. The camera unlinks from your account and resets, same as the SYNC-button method.

An offline camera won’t respond to this — check our best eufy camera guide for current models if a camera won’t come back online at all.

The HomeBase itself: where a eufy reset gets risky

This is where eufy breaks from every cloud-first brand we’ve covered in this series. The eufy HomeBase stores recordings locally — the entire reason buyers choose eufy over a subscription-based brand like Ring or Arlo. Per eufy’s own support documentation, a factory reset of the HomeBase (not just a paired camera) erases every recording stored on it, with no partial or “soft” option that clears settings without touching footage. A basic reboot — unplugging the HomeBase and plugging it back in — does not erase anything and is the safer first troubleshooting step.

Before factory-resetting a HomeBase:

No cloud-first brand in this series has an equivalent risk, because their recordings never depend on a piece of hardware sitting in your own home.

It’s not just eufy

Ring, Nest, Blink, Arlo, and Wyze each split their reset process differently — Blink’s Sync-Module cameras and Arlo’s SmartHub-connected models are the closest architectural match to eufy’s HomeBase setup. None of them carry eufy’s specific footage-loss risk, though, since none of them lean on local storage as the core pitch the way eufy does. See our cloud vs local storage guide for the fuller tradeoff.

Will a reset delete your eufy video history?

It depends which device you reset. Resetting a single camera — eufyCam, SoloCam, or Indoor Cam — does not touch footage already saved to the HomeBase or to optional cloud backup; you’re just re-pairing the camera itself. Resetting the HomeBase is the one action in this whole series that can permanently erase recordings, since that’s where eufy’s local storage actually lives. Cloud-stored footage under an optional eufy backup plan is never at risk from either kind of reset.

The bottom line

For most eufy cameras — eufyCam, SoloCam, Indoor Cam — factory reset means holding the SYNC button 8-10 seconds until you hear a beep, or using Remove Device in the eufy Security app if it’s online. The one step that actually carries risk isn’t the camera button at all: resetting the HomeBase wipes every local recording stored on it, a tradeoff unique to eufy’s no-subscription, local- storage model. Reboot first, save any footage you need, and reset the HomeBase only as a last resort. Still stuck after a proper reset?
