Yes, it’s typical. I have commented before that it renders the purpose of live view and audio almost useless. That together with the low volume, when used as an outdoor camera, its purpose, renders it totally useless in that regard. One of mine is 50 yards from the road, has a lot of bushes in the way to screen the road noise, but nobody ever even hears me, if I try to talk to them, and it’s in a semi enclosed porch, only 4 feet from their left ear. Works well enough to be useful indoors, but that isn’t their purpose.
I’m still satisfied with my purchase, because I didn’t get the system for that, but making a play of two way audio is just marketing hype.
