TigermanThey did some job on security, such as closed external network IP and port login, camera communication encryption, forbid ed key ini file download and a lot staff I don't understand. However, I wouldn't believe anything is 100% secure nowadays.
DarkvikingThanks. I've always liked the idea of this sort of camera, but the potential risks of having strangers take over your cameras is pretty scary, so I haven't got around to doing the research needed to make sure they're secure.
