Do condo windows degrade Eero's signal?

Hi,

I'm trying to troubleshoot why my Google Nest cams seem to have intermitent connectivity despite being 1 foot from my Eero extended, although connecting through thick condominium glass.  I've tried replacing my Nest cams just to be safe, but the problem seems to come back.  My cams drop on and off constantly.

Is condo glass too thick for the wifi signal to pass through with stability?  Thanks for any assistance.
