Those old quotes need updating. Wyze has put some effort into allowing the cams to run [somewhat] without Internet now, but it is still VERY messy. TLDR: So still best to run WITH Internet, for sure.
First, let me say for any “before”, “used to be”, or “older” quotes I used V2 firmware 18.104.22.168. For “now” or “newer” quotes I used firmware 4.9.98 (not the current version, but newer), and for the app I used the current production versions of 2.12.35 (Android) and 2.12.51 (iOS).
The V2 cams still need Internet to boot. That hasn’t changed. After boot, you can lose the Internet connection and still maintain SD card recording. That hasn’t changed.
Before you had to pull the SD card to view the recordings because you couldn’t get the app to work properly without Internet access. That restriction still appears to still be true for the iOS apps (although the phone and iPad versions fail for different reasons), but not the Android app. The Android app now [mostly] functions without Internet access.
Due to periodic reauthorization, you used to lose live stream capability after a few minutes (5-7 if I remember). However, I find V2s with newer firmware were still streaming after 30 minutes (I didn’t test beyond that). Further, I found V2s with old firmware could be brought back online for a few more minutes using the current production [Android] app by just pressing reload.
The app used to re-authorize every time you changed views (like from group mode to single cam view), but I find the Android app no longer has that restriction, not even with an old firmware cam.
If the Wyze app is not running before you lose Internet, then you will find the Android app loads and [mostly] functions, whereas the iPhone will not be able to communicate with the cams, and the iPad will ask you if you want to add new devices, not recognizing the old ones.
So – still best to run WITH Internet for sure, especially since you are running iOS. Just plug the second router into the first one and let it have Internet access. That would give you 2 WiFi networks (hopefully on different channels) and still allow the snippets of Internet access the Wyze system needs for authorizations and things stored on the servers, like settings and shortcuts. The second network will need a different name and password. You would want any local devices (iPad, for instance) that view live streams connected to the secondary Wyze WiFi network to accomplish your goal of minimizing traffic on the primary network (note the cams don’t use the network much if someone isn’t viewing them).
As for a router recommendation, know that Wyze currently only uses type ‘N’ router capability, so don’t go too nuts buying something faster like an AC router to run only today’s Wyze devices.
@wyzegwendolyn – can we relay these differences between the iOS app and the Android app to the developers? The apps should work the same. Also, on a totally separate issue, I love that when I call up a group of cams in portrait mode on the Android side the screen automatically re-orients. It doesn’t do that on the iOS side. Instead I have to reach over, pick up the tablet, and rock it back and forth to get the proper orientation. So a code comparison between the apps would be great! Right now the Android app is definitely my preferred app, although it crashes often on my Fire HD 10 tablet. I send a new log each time a new version of the app is released, hoping they can fix that issue.
