Is there a way of telling if indoor survellence cameras have audio connected to them will I see certain wires if so what do they look like
The wires are so small and hidden that it would be hard to tell. However, if you looked at the camera good enough, you should be able to see an audio port or tiny speaker.
That depends entirely on what kind of cable is used. Some cameras are even wireless, so there are no cables at all.
Not really, if its an older camera you may be able to see the wires.
