Surveillance Camera Selection and Troubleshooting

Surveillance cameras are used as security cameras. Their pixels and resolution are higher than those of computers. However, they are not able to catch up with professional digital cameras or DVDs. The surveillance camera is just a single video capture device and it does not have data storage capabilities.

For the average person, the biggest difficulty in buying a surveillance camera is not knowing what to choose, so Xiaobian tells you today.

So for this person in charge of Yabang Technology: "Strictly follow the product manual for proper operation, such as operating temperature, power supply voltage, etc. The temperature index of most surveillance camera manufacturers is -10 to +50°C, if used. The temperature and humidity of the large changes should be added special protection.Because the domestic surveillance camera AC voltage adaptation range is generally 200 ~ 240V, anti-power voltage change ability is weak, when used in the system need to add a regulated power supply."

Troubleshooting

The network camera is a new generation product combining traditional camera and network video technology. In addition to all the image capturing functions of the traditional camera, the machine also has a built-in digital compression controller and WEB-based operating system, making the video data compressed. , to the end user via LAN, internet or wireless network. With the birth of H.264 digital video coding standard, the quality of network transmission video images has also made a qualitative leap. So what are some of the problems that often occur with webcams?

1. When the network camera is installed, your searcher cannot find the IP address of the network camera.

On this issue, first of all you need to confirm whether your network cable and power supply are installed correctly. If the camera still cannot find the IP after confirming, then you must confirm your network segment and see if the network camera network segment is the same as the network segment of your computer. If it is not the same, you need to put it. The network camera network segment is the same as the network segment of your computer. Your computer can find the IP address of the webcam.

2. After the network camera is connected, the internal network can already be watched, but the external network cannot watch it.

There are two factors on this issue. The first is that there is no port mapping, because each camera is to transmit the signal and watch it through the monitor. If we do not do port mapping, the signal will not be sent out, so the signal will only be in the internal network, so that the external network can not accept the signal, making the external network monitor can not monitor the scene in real time. Another problem is the domain name of your computer. Check if you log in. In general, the network camera's external network access address and domain name are directly linked. The IP camera's external network access address can be your computer's external network IP address. The port number can also be your domain name information plus the port number.

3. When connecting 5 cameras, why is there only one camera?

The problem is because you did not change the IP address and port number of the IP camera. Because the IP cameras connect multiple IP cameras, the IP address and port number of each IP camera cannot be the same. Otherwise, no IP address or port number is the same. The video of these two cameras will conflict, the video will be distorted or there will be no video at all. For example, if the signal is flowing, the port number is treated as the outlet of the flowing water. If the port number is the same, the river of that one will be separated and left to the same other outlet. You say that the video signal is Isn't there a conflict, can such video play normally? And the default IP and port of the IP Camera are the same, so you said that you connected 5 cameras, but you did not change the IP and port number of the 5 IP cameras, the video will naturally conflict, so it can only appear A webcam.

In summary, some basic problems of network cameras are these. Of course, with the development of society, the application of network cameras will become wider and wider, and even network cameras will become the mainstream products of surveillance cameras.
