FWIW

There is a concern with using any radio transmitting device in that you are NOT the only one that can receive the transmissions.

Admittedly the signal strength is not very high and has a rather limited range, but it could also provide others with the same view that you have, which is why I encourage folks to keep their computer and laptop cameras physically covered when not in use, it is TOO easy for them to be hijacked without your knowledge.
