What This Problem Means

  • No motion alerts being received
  • Live View fails to connect
  • Device shown as offline in the Reolink app
  • Last event shown in the app was some time ago

Safe Checks You Can Try

1. Check the battery level

Open the Reolink app and go to Device Settings or Device Info to check the battery level. If the battery is low, charge it via USB-C until the indicator shows full, then reinsert and wait for the device to reconnect.

2. Restart the device and router

Press and hold the power button on the camera for about 5 seconds until you hear a prompt tone, then release. Wait 60 seconds for it to restart fully. Restart your router by unplugging it for 30 seconds too. At the same time, restart your router by unplugging it for 30 seconds.

3. Check Wi-Fi signal strength

In the Reolink app, go to Device Settings and check the Wi-Fi signal indicator. A weak signal is the most common cause of battery cameras going offline. Move the camera closer to your router, or add a Wi-Fi extender between the router and the camera.

4. Check for network changes

If you have recently changed your Wi-Fi password, upgraded your router or switched broadband provider, the camera will have lost its saved credentials. Open the Reolink app, go to Device Settings and reconnect to Wi-Fi with the new details.

5. Check the Wi-Fi band

The Reolink Argus 3 Ultra supports 2.4GHzand 5GHz. If your router merges 2.4GHz and 5GHz under one network name, try separating them and reconnecting the camera to 2.4GHz for better range.
