Methods of connecting network-based cameras to video station such that the ownership between the network-based camera with the respective connected socket can be locked, such that at any time, each of the at least one socket can lock ownership of only one network-based camera, and receives video from the only one network-based camera with ownership locked by the respective socket. As the socket of the current invention can now engage into “locking” relationship with only one network-based camera with camera-identification tag acceptable to the video station, and preferably with the lock key, the chance of spoofing can be substantially reduced.
