V3 cameras all off line what's going on?

Hello. I’m new on this forum. Just signed in, to find out if there are others with Cam v3 problems, and looks like this is happening to quite a few.
Slowly but surely each of my 10 cameras one by one started loosing connections. To the point that some don’t connect anymore and the app shows them either off line, or, when I bring them at my desk to reset and test, are very slow to connect, and eventually got error code -14. Or back to off-line.
I just renewed my subscription, for one more year, and it seems is going to be the last, for both Wyze and I. I’m not sure what’s the expected life of these cameras, perhaps they only last 3-4years, and it’s about time to try others.
Other than that, I don’t have time for the “gymnastics” suggested in this thread. All my environment is stable and forever works for everything else.
Wyze fooks, would you comment on the life expectancy of these devices used outdoors in zones 5-6.
Thank you.
