What's wrong with CMS2.0 webcam network?

The camera is not connected to the video recorder. If so, as far as I know, there is 1 Are the interface lines at both ends of the network cable in the same order? 2. Whether the network cable distance is too long, if it is too long, the signal attenuation will be serious, and a switch needs to be added in the middle; 3. Power supply mode (long-distance power supply-generally powered by poe separation line, short-distance power supply-power supply is next to the camera). If the power supply is long-distance, you need to consider the current of the power supply. If the current is small, it may be insufficient power supply; 4. The highest resolution of the camera must be the same as that of the video recorder. If the camera is 400W and the video recorder is as high as 200W, the network will be blocked. 5. Is your camera network segment and video recorder in the same network segment? If not, you need to change it, or set the camera to IPV4 automatic acquisition.

Because your question is vague, cms2.0 is a software that can be monitored remotely, so I don't know if you mean that the camera can't be connected to the video recorder or the camera can't be accessed remotely. If you can't access remotely, you need to consider three modes of network card binding, multiple access and fault tolerance in your video recorder, and normal network settings can be found. In addition, if your camera is a wireless device, you must consider whether the camera is successfully connected to the router. If the connection is successful, the parameters to be entered in cms2.0 must be consistent with the camera.

Please correct me if there are any mistakes and thoughtlessness.
