- Who:
- you, with the eufy power adapter and cable from the box.

Check the 2.4 GHz wifi signal next to the camera
- Who:
- you, with your phone beside the camera and the eufy app.
- How:

- Result that matters:
- learning whether the camera is too far from the router or behind too many walls.
- If the signal is weak:
- move the router closer to the camera if you can and keep other devices that may interfere away.
- If the signal is good:
- try the phone hotspot test.
- Evidence to keep:
- a screenshot of the wifi strength shown in the app.

What it means
In its LED status table for eufy IndoorCams, eufy states that red blinking slowly means the camera is disconnected from the internet; solid blue is the normal state. Its Indoor Cam Offline article lists an unstable or non-original adapter, a weak wifi signal, a changed network name or password and a router without internet as reasons. The LED alone never proves the camera is faulty, and other eufy models use different colours.
