During setup to a Netgear router that has no password security, I do not get the option or button for no password.
This is from the Wyze Cam Setup guide on the support site:
Note: Wyze Cams require a minimum of WPA network security, and cannot be set up on a network without a password. As such, the password field within the Wyze app has to be filled in for the ‘Next’ button to become active* .
Always want to make sure you have a password on your WiFi you are vulnerable to so many things not only that but you probably have random neighbors connecting and slowing down your speeds !
