But we can also access DVR system on the browser by its IP locally, not by SN. Here is the method.

1. Plug the NVR system to the router with a network cable.

2. Find DVR‘s IP.

3. Get a computer which is connected to the same router as DVR is to access DVR with its IP on the browser. The default user name is admin and password is none.
