Is that how they work or are you just speculating wildly about things that are easily looked up in a few minutes?

Flock is a new in this market, before Flock there were loads of cameras wired up because wifi was not considered reliable until recent times. I'm asking, how do you detect well placed, subtle wired cameras? My overall point being, these apps are only as good as long as Flock and others don't just go fully hardwired (which before Flock, many were!).
