Why Does My eufy Camera Keep Going Offline Every Night
- Scheduled router reboot at night
- Night power-saving on the camera/router
- Low battery reached overnight
Problem Description
Your eufy camera keeps disconnecting overnight and shows offline every morning. You wake up to find hours of missing footage during critical overnight hours. The root cause is almost always router WiFi power-saving settings that kick devices off during low-activity hours. eufy support rarely provides this fix.
Why This Happens in Real Homes
A eufy camera that reliably drops offline every night and returns by morning is following a nightly pattern — the most common being a router that's scheduled to reboot overnight, a night power-saving setting, or a battery that drains just enough by the small hours (accelerated by cold and by IR night mode's higher draw) to tip a weak-signal camera offline.
Check your router for a scheduled nightly reboot and disable it, and turn off aggressive night power-saving on the camera or router. Make sure the battery reliably lasts overnight (charge it or fix solar), since cold nights and night vision drain it faster. Improve 2.4GHz signal and reserve a fixed IP so it reconnects cleanly, and update firmware for known nightly-drop bugs.
Symptoms
- Camera goes offline every night
- Drops overnight, back by morning
- Nightly disconnects
- Offline at a consistent time
- Reconnects on its own
- Night recordings missing
- Only nighttime drops
- Recurs daily
Recognize these? Here's what usually causes it.
Common Causes
- Scheduled router reboot at night
- Night power-saving on the camera/router
- Low battery reached overnight
- Cold night temperatures dropping the battery
- 2.4GHz interference peaking at night
- IR/night mode increasing draw then dropping
- Weak signal tipping over at low battery
- Firmware bug
Most fixes happen in the first 3 steps.
If eufy cameras went offline after a firmware update and will not come back this is a known issue. Contact eufy support referencing the specific firmware version. Some cameras have been bricked by forced updates.
Tools & Requirements
Step-by-Step Solution
Correlate nightly offline times with network events
Check router logs and camera status around the same nightly window, because repeating schedule-based outages usually indicate network maintenance or RF noise patterns.
Evaluate WiFi interference and channel congestion
Measure nighttime channel occupancy and adjust router channel if needed, since neighborhood congestion spikes can trigger predictable overnight disconnects.
Disable router features that rotate leases aggressively
Review lease times and power-saving WiFi policies, because aggressive lease churn or nighttime optimization features can drop IoT devices repeatedly.
Set static DHCP reservation for the camera
Assign a stable IP lease to the camera to reduce reconnect overhead, because IP churn plus weak signal often creates recurring offline loops.
Validate overnight uptime after network tuning
Monitor camera status through two consecutive nights to confirm the fix is sustained, then escalate with logs if offline windows persist.
Quick Solutions
Still having issues? This is usually the deeper cause below.
This usually happens right after a router reboot or ISP change — the device rejoins the network but drops its cloud session silently.
Set up a daily automated router reboot at 3am if available. This clears memory leaks and stale connections that cause increasing instability.
Most WiFi drop-offs happen right after a router reboot or ISP swap — the device reconnects to the network but silently loses its cloud registration.
