possible but you can get that data on public access security cameras on high traffic areas where people walk and interact with each other so no point in risking exposure of it
if they manage to make a android body that runs silent then with enough effort the bodies could blend in with normal humans and only a malfunction or lazily made fake breathing setup could give them away, you can literally have them cycle heated air through to simulate breathing that serves no other purpose than to fool humans that there is inhalation going on, eyes are another thing that would probably not pass under close inspection but if you're at that distance you're already suspicious for some reason
