Don’t worry too much about it. RTSP probably won’t affect you at all.
To overly simplify what they’re talking about in a way that’s easier to understand, “RTSP” is like an EXTRA special type of program some people like to install on their cameras so they can use them in a different way than everyone else. It lets you record video onto your computer easily, or connect to the camera locally through your router instead of going through the internet, and some stuff like that. It is something most people don’t use. Some of us (including me) like the benefits from this special option, but most people won’t use it or care. If you’ve never heard of “RTSP” then it’s almost definitely something you don’t need to worry about. It won’t affect you.
The OS issue will probably mostly affect people with older tablets that will no longer be able to use the new Wyze app. Hopefully people can still use the earlier versions of the Wyze app on older devices. Even if older versions can’t be downloaded and installed from Google, there are places online that store older versions of apps (secure and trustworthy) that we should hopefully be able to link people to to still be able to use. Just newer features won’t be available, and hopefully newer updates won’t cause issues with the older app versions, but we’ll have to see how it plays out.
As for phones, sure, not everyone can afford $1K phones, but there are phones and tablets selling for as little as $50 to own outright that support Android 7. Or there are always specials and options to get brand new phone at $0 down and $0 monthly cost with a 2 year contract for phones that support the latest OS, so it’s not really accurate to indicate someone needs to spend a ton of money to get a phone that will work with Android 7 or higher. Don’t worry too much about all of that. This requirement to have at least Android 7 will be something that does not impact very many people (most won’t notice a difference). If you have a phone older 2016 (more than 5 years old, so like 6+ years old) then you probably need a new phone anyway because there are TONS of apps that refuse to work with OS’s that old, and it shouldn’t be a surprise because there should’ve been tons of other apps refusing to install already. Wyze will not be doing anything the majority of active App developers already require. It will make things better for the majority of users by not having to cater to ancient standards.
