I just got a Tenvis TH661 network camera which works rather brilliantly with my iPhone to let me remotely view my house and garden (I don't need to - it's a fun toy!).
My question is about how these things handle data.
Does the camera upload its video stream on demand (ie only when I use the app to view it), or continuously (using up data upload capacity all the time)?
The first would seem logical but I have no clue how this stuff works. I presume the app needs a server to tell it what dynamic IP my computer has, so maybe data goes through that server?
