(1) If it is in a local area network, just put the IP in the hard disk video recorder and the computer IP in a network segment. If you want to connect directly with a network cable, the method is the same. You must first divide the IP into a network segment, then connect it with a crossover network cable and access it through IE.

(2) If there is only one hard disk video recorder, there is no need to buy a switch. You can use a crossover cable (A at one end and B at the other) to connect the hard disk video recorder and the computer. Using computer to access and control the hard disk video recorder: use IE browser to enter the http:// IP address and port number of the hard disk video recorder in the address bar, and then press enter to open the login page. Just enter the account and password of the hard disk video recorder administrator.

(3) The hard disk video recorder itself is a host, which has independent monitoring functions such as recording and operation, and does not need to be connected to a computer. Because the hard disk video recorder is a host with independent working function, even if it is connected to the computer, the hard disk video recorder can record normally when the computer host is turned on or off. Nowadays, video recorders basically support network access. You can play the recorded surveillance video by connecting the video recorder and the computer with a network cable, installing CMS software, or accessing the IP address of the video recorder through a browser.
