Because of security / privacy concerns, there are some of us who have purchased Wyze cameras, but do not want to install them on a network that is accessible from the internet.
Ideally, you should be able to set up a wireless access point / router that is not connected to the internet (i.e. a private network) and have a PC or Android phone running the Wyze app also connected to that private network in order to view the files recorded on cameras. Removing the SD cards from the cameras and plugging them into a PC is not an acceptable method since the cameras might be installed in places that are not that accessible.
When I try to add a new device to the Wyze app on my cellphone, the setup process seems to block when it is pulling up a list of cameras for you to select from if you are on a network that is not connected to the internet. I tried temporarily connecting it to the internet to complete the setup, and then running the cameras without the internet connection, but the IP address it was inheriting was from the main network, not the WAP that was destined to be not connected to the internet. I could not find an option in the Wyze app to manually change the IP address associated with a device. It seems that it wants me to reinitialize the device and install it again, but to do so would just be a duplicate of what got me in the situation in the first place.
