Dahua network camera connected to mobile phone network abnormally.

It is possible that the network speed is unstable or the protocol compatibility is poor. You can check the internet or contact customer service.

The reasons and solutions for this situation are as follows:

First, the network speed is unstable or the protocol compatibility is poor. Only one webcam or three or two webcams are connected, which is caused by network instability, mainly because the processing capacity of the switch is not enough. When there are many webcams, it can't be handled.

Second, there is something wrong with the production of the network cable. The network cable is too long (generally not more than 80 meters) or the network port is not pressed well, which may also cause the network speed to fail to keep up. You can change a shorter network cable to see if this will happen to the same camera, and you can rule it out.

Third, if a single webcam is connected to a video recorder in a short time, this will also happen. The communication protocol between network camera and video recorder is not very compatible. It is recommended to try again with different brands of products.

Fourth, the exception is that there is no problem at first. This will happen when used for a long time. Generally, it is caused by hard disk failure, hard disk damage, or using ordinary civilian hard disks and reading and writing too many times. It is recommended to replace the dedicated hard disk for monitoring. Seagate is generally better.
