The Nest Cam (battery) is set up in the Google Home app by scanning the QR code on the camera, and owners who fail at this step report the same three causes. First, the phone: the app needs Bluetooth and Location, and Nearby devices on Android, and the phone must be on the Wi-Fi network the camera will use. Second, the network: the camera joins a 2.4 or 5 GHz network, and a guest network, a captive portal or a router with client isolation blocks it; the 2.4 GHz band reaches further, which matters for a camera outdoors or in a distant room.
Third, the camera itself: it needs charge, so plug it in or charge it before setup, and if it was set up before, reset it first. Setup should be done close to the router and then the camera moved to its position, because a weak signal at the mount makes the camera fail partway through. Some phones with battery optimization on for Google Home stop the app when it is in the background, which interrupts setup at the Wi-Fi step, so keep the app open and the screen on during the whole process and disable battery optimization for it.

A weak signal where the camera is
What separates it Setup fails at the Wi-Fi step
How to confirm Set up near the router, then move the camera

A guest or isolated network
What separates it The camera cannot connect
How to confirm Use the main network, with no client isolation
- 4
A flat battery
What separates it The camera does not wake
How to confirm Charge it before setup
- 5
A camera set up before
What separates it The app says it already belongs to someone
How to confirm Factory reset, then set it up again
Before you touch a setting
Record this first — changing settings destroys the evidence
- The phone, app version and permissions
- The network band and name
- The camera's charge level and indicator light
- Whether the camera was set up before
Try in this order
0 of 6 completedCharge the camera
ReversiblePlug in the charging cable or charge the battery fully before you start.
Check the phone's permissions
ReversibleAllow Bluetooth, Location and Nearby devices for Google Home, and join the phone to your main Wi-Fi.
Set up near the router
ReversibleStart setup within a few meters of the router so the camera finds a strong signal.
Scan the QR code
ReversibleIn Google Home, tap Add, Set up device, New device and scan the code on the camera.
Reset if it was set up before
ReversiblePress and hold the camera's reset button until it announces the reset, then repeat setup.
Move the camera and test the signal
ReversibleAfter setup, place the camera and check in the app that the live view loads.
Model-specific
What is true of this model and not of its siblings
- Set up close, then move
- A weak signal at the mount is the commonest cause of a failed setup.
- The QR code
- The code on the camera links it to your account in the app.
- Guest networks
- They often block devices from talking to your phone.
Stop boundary
When this stops being a self-service repair
- !If setup fails on a second phone and a second network, contact Google Nest support
- !If the camera belongs to another account, the owner must remove it
- !If it will not wake at all after charging, ask about a replacement
