The reason for the bad effect of installing the wireless bridge

Customers are often heard to say that wireless bridges are not effective, with large delays and poor stability. Some people even dare not use wireless bridges to build systems. In fact, not all wireless monitoring devices have poor stability, but there is no choice of the product or the small details of the installation process did not pay attention to the emergence of the problem.
The effect of wireless bridges depends not only on the effects of the equipment, but also on the site environment, installation methods, cameras and other factors. The following Feng Runda Xiao Bian to introduce the wireless monitoring equipment installed after the effect of poor reasons.
1, the performance of the device itself
Wireless monitoring equipment is divided into low-end, mid-end, and high-end types. Generally, the transmission distance is relatively short, and the use of low-end products can meet the basic requirements when the amount of data is not transmitted, but the stability is not guaranteed. In order to save costs, some devices choose some relatively low-cost components and choose unsound motherboards and other hardware devices.
The requirements for the performance of the bridge equipment for transmitting video signals are relatively high. Therefore, it is better to choose a mid-to-high-end wireless bridge to build a wireless monitoring system to ensure the stability of the system.
2, equipment frequency selection
In the urban environment, we should use 2.4GHz wireless monitoring equipment as little as possible. In our surroundings, the use of 2.4G is quite a lot, and the frequency of many home appliances is also 2.4G. Excessive equipment can cause interference and eventually cause poor results. In a more complex or harsh environment, it is recommended to use a 5.8G wireless bridge to set up a wireless monitoring system. Because of the high frequency, 5.8G wireless bridges will be much more resistant to interference.
3, antenna selection
The knowledge of wireless accessories is also quite a few, and the same 1 connector, or feeder, power supply, etc., have a lot of price difference. Some customers in the early selection of wireless monitoring equipment, desperately lower prices, of course, businesses are not willing to do lose money business, it can only be out of sheep, and can only reduce equipment accessories and other configuration specifications.
4, image links
The reasons for the image cards are as follows: The net bandwidth is not enough. Many inexpensive 300M wireless bridges on the market are shoddy. Such wireless bridges can transmit video signals one by one at close range. In the case of monitoring, there will be problems such as insufficient bandwidth; the processing capacity of the wireless motherboard chip is insufficient. Many people easily overlook this detail, including Taobao.com, 300 bridges, and 3000 bridges. It also indicates how far it can be transported, and their processor chips will be in many different grades, often with enough bandwidth. The chip processing capacity can not keep up. This can also lead to image cards, long delays, and so on.
5, the choice of switch
For digital wireless monitoring systems, not only should a stable wireless bridge be selected, but the configuration of the switch should not be too bad. First, the switch should be selected according to the number of front-end transmission images and the total bandwidth of the front-end equipment. When choosing a switch, pay attention to the backplane bandwidth of the switch and the packet forwarding rate. To meet the transmission requirements, you can ensure the stable transmission of signals. If the requirements are not met, there will be problems such as delay or packet loss in image forwarding.
6, the choice of connection cable
At present, most of the cameras are high-definition cameras. Therefore, cables used in the construction of monitoring systems must use Super Category 5 or Type 6 cables to ensure stable signal transmission.
The length of the cable is also required. The length of the network cable from the network camera to the wireless bridge must not exceed 100 meters. The length of the cable between the wireless bridge and the POE power supply module must not exceed 30 meters. The communication between the wireless bridge and other devices must use a straight-through connection.
7, installation, debugging
Installation, a simple look, I feel everyone will, in fact, experienced and inexperienced technical staff, in the same equipment, the effect of installation is still a certain gap. Personal advice, if there are relatively many wireless video points, and you are involved in the wireless video surveillance industry, it is best to ask a professional to help you debug.
Commissioning, mainly pay attention to the following: frequency, channel, power, it is recommended that you first contact Feng Runda technical staff.
8, camera reason
Of course, there is a situation that causes the image to be unclear, that is, the camera selected by the customer itself is not effective.
As long as the project to avoid the above issues as much as possible, the clarity, real-time, and stability of the wireless video surveillance system are still good. A stable wireless video surveillance system We can't judge the quality of a wireless surveillance device alone. We can't ignore every small detail and every small component to ensure a stable wireless surveillance system.
