Wrong. It (like all Wyze cameras) requires a WiFi connection in order to watch it, but it will record to the uSD card just fine without a WiFi connection. One important note is that after powerup, the Wyze cameras are essentially brain dead and will NOT start recording to the uSD card until they are able to check in to the Wyze servers. Once the cameras have checked in, a WiFi connection is NOT required as long as power is not killed.
In my case, the cameras in my truck connect to my WiFi when I’m at home.
