Do more than 20 webcams use computer mainframes or hard disk video recorders?

Of course, it is best to use 32-channel hard disk video recorder for more than 20 network cameras.

The specific reasons are as follows:

1, the hard disk video recorder only deals with video acquisition, storage and playback, and the special plane is dedicated, so it is stable and not easy to go wrong. Compared with the computer mainframe, work is not easily disturbed.

2, the computer host is also limited by the stability of the operating system, which is prone to problems after a long time. Hard disk video recorder itself is designed for long-term use, generally using Linux system, which is relatively stable.

3. Compared with computers, hard disk video recorders have lower power and are more energy-saving when used for a long time.
