I think a camera uploading video 24/7 can use noticeable bandwidth if your internet or router isn’t great. I’d personally prefer putting cameras on 2.4 GHz for better range, and maybe lower the stream quality or switch to motion-only upload to cut the impact. Not totally sure though, it depends on your router and upload speed.
Looks interesting, but the non-invasive glucose claim seems sketchy to me, I think I’d only use it for rough trends and not trust it as a real meter, maybe someone else has actually compared it.
