Eufy stopped securing my house

Hi folks,

Since a few weeks my eufy security has a lot of troubling keeping up the security. First I thought it was my Homebase s380 so eufy send me a new one. I bought 3 new c31 wired cams with it to upgrade my equipment. I have 11 security cams working on the Homebase and need the 24/7 recording. But since a few weeks the cams going offline, stopped for a while and go back online, keep recalibrating every few minutes so recording stops, doesn’t record anymore, goes offline for no reason.
We changed nothing in the WiFi or something else. What can be a solution for this because I’m really at the point of going to explore other brands because i need the 24/7 security
