Does the eufy Indoor Cam C120 record if it is not plugged in?
Frequently Asked Questions - 11/05/2026
Response Notice-Facile

No, the eufy Indoor Cam C120 will not record if it is unplugged. This camera operates exclusively on mains power via the provided cable and USB adapter. It does not have any built-in battery and relies entirely on electricity to function.

When the camera is unplugged or in the event of a power outage, here is what happens immediately:

  • Recording stops immediately
  • The video cannot be saved
  • Two-way audio no longer works
  • Live access to the camera via the eufy Security app becomes impossible
  • Motion detection notifications are no longer sent

As soon as power is restored, the eufy Indoor Cam C120 automatically restarts and resumes normal operation with the connection to your eufy Security system. The camera reconnects to your Wi-Fi network and resumes recording.

If you want to protect your surveillance in case of a power outage, you can connect the camera to a UPS (Uninterruptible Power Supply). This will ensure continuous power to your camera during a power cut and preserve your recordings. Just make sure that the UPS has sufficient capacity to power the camera (the provided adapter consumes 5V/1A).
