The max length is dictated by the Ethernet specs. About 100 meters is the practical limit.
Thank you. Few more doubts

1.If NVR has one single I/P from the switch, how can it identify each camera individually?
2. So the number of cameras that one can install is dependent on the number of Ethernet ports on the switch?
3. Can the Ethernet port on the Switch provide enough juice to power up the camera?

Each IP camera has its own IP address. Cameras can be powered via POE switches.
