Your WiFi data is sent via the QR code during setup. If you want to change your WiFi for the Wyze Cam v1/v2 and Wyze Cam Pan You will need to walk through the Setup process again so that a new QR code can be generated and your cameras can create a new connection with your new WiFi network name and password.
On the Home tab of the Wyze app, tap the [...] in the upper right, then select "Add a Product" to start a new setup for the camera. Follow the prompts on the screen to setup your camera again.
You can learn more about the setup process with our Wyze Cam Setup Guide.
