Choppy video, audio across 8 devices

I have 8 different devices in 2 locations. Each location has high speed Internet. My home just tested out at over 200 gbs. I am using ring doorbell 2, ring doorbell pro, floodlight Cam, and spotlight Cams. All provide choppy video and audio. Live video use on all devices is too slow to respond to activity alerts. I don’t know if this is inherent and all ring products but based on these 8 devices and 2 separate locations it appears to be.
I want to believe that I can make these work but I am not accepting that this is some kind of interference randomly from other devices because they are anywhere from 10 to 50’ from the router and my high speed Internet is very fast. The issue is accross all devices.
I am hoping there is a magic solution other than wasting endless hours with tech support trying to tinker with 8 devices.

The time lag from a person ringing your doorbell and you getting the alert is a function of both your Home network and the Cellular network you subscribe to. I have over 200 Gbs service and there is considerable lag especially when the Cellular network is overloaded, this problem is very prominent.

As for your network without knowing what type of router you have, you may be limiting your home network response by the number of devices on your network. A router that allows up to 50 devices and capable in prioritizing the devices is preferable.
