Network camera is a new generation product combining traditional camera and network video technology. In addition to all the image capture functions of general traditional camera, the machine also has built-in digital compression controller and web-based operating system, so that the video data is compressed and sent to end users through LAN, Internet or wireless network. With the birth of H.264 digital video coding standard, the quality of video images transmitted over the network has also made a qualitative leap. So where are some of the common problems with webcams?

1. After installing the webcam, your searcher cannot find the IP address of the webcam?

For this problem, first you need to confirm whether your network cable and power supply are installed correctly. If the camera still cannot find the IP after confirmation, confirm your network segment to see if the network segment of the webcam is very the same as that of your computer. If not, you need to change the network segment of the webcam to be the same as that of your computer.

2. Why is it that after the webcam is connected, the Intranet can watch, but the Internet can't watch?

There are two factors on this issue. The first is that there is no port mapping, because each camera needs to transmit the signal and watch through the monitor. If we don't do port mapping, the signal can't be sent out, so the signal will only be in the intranet, so the extranet can't accept the signal, so the monitor of the extranet can't monitor the situation of the project site in real time. Another problem is the domain name of your computer. See whether you log in. Generally speaking, the Internet access address of the webcam is directly linked to the domain name. The Internet access address of the webcam can be the Internet IP plus slogan of your computer or the domain name plus slogan.

3. Five cameras are connected. Why is there only one camera?
This problem is because you didn't change the IP and port number of the webcam, because the IP and port of each webcam cannot be the same when multiple webcams are connected. Otherwise, if no IP or port number is the same, the video of the two cameras will conflict, and the video will be distorted or there will be no video at all. For example, the signal is regarded as water, and the port number is regarded as the outlet of water. If the port number is the same, the river will be separated and left to another outlet. Do you think there will be conflict between such video signals, and can such video be played normally? Moreover, the default IP and port of the webcam are the same, so you connected five webcams, but you didn't change the IP and port numbers of the five webcams. The video will conflict naturally, so only one webcam can appear.
