Tools & Requirements
Step-by-Step Solution
Charge the Battery
Charge the Arlo battery to 100 percent with the official charger. Low charge can prevent the camera from completing sync.
Reseat and Power Cycle
Remove the battery, wait 10 seconds, then reinsert it firmly until it clicks. Close the latch and wait for the status light.
Rejoin WiFi
Open the Arlo app and tap Add Device. Follow prompts to sync the camera to your WiFi network again.
Update Firmware
Once online, check for firmware updates in the app. Apply any updates to stabilize connectivity.
Confirm Live View
Open live view for several minutes to confirm the camera stays online and records motion events.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If pairing fails after multiple attempts, the device may still be registered to a previous account — factory-reset it before trying to add it to a new one.
Use the Arlo charger and let the battery reach a full 100 percent before attempting to sync.
Pairing failures almost always come down to distance during the initial handshake — manufacturers seriously understate how close you actually need to be.
