The long-distance wifi image transmission module wireless video surveillance system plays an important role in the field of forest fire prevention. Not long ago, a serious fire broke out in the Amazon forest, the fire continued to burn, and new fires occurred frequently, leading to Brazil. The border between Peru and Bolivia was the worst hit by the fires, taking a huge toll on the local economy.
Forest fires occur almost every year, which have caused great damage to the forest ecological environment. It is the number one killer of natural disasters. How to effectively prevent forest fires is a concern of all countries in the world. In recent years, China has adhered to a policy of sustainable development, strengthened preventive measures in key domestic forests, and installed and improved wireless video surveillance systems for these areas.
The long-distance wifi image transmission module forest fireproof wireless transmission system can meet the following requirements:
1. Identify forest fire sources in time, play the role of early prevention and timely rescue.
2. Reasonably arrange fire fighting plans to reduce forest fire fighting costs and economic losses caused by fires.
3. Improve the comprehensive ability of forest fire prevention to ensure the life safety of surrounding people.
In response to these needs, our company has 20 years of wireless transmission experience, and has designed a complete forest fire prevention wireless transmission system for forests, with long-distance wifi image transmission module as the main transmission device. The wireless adopts self-developed modules, which have the advantages of high bandwidth, high stability, long transmission distance, support for encryption, waterproof, sunscreen, dustproof, lightning protection, and high oxidation resistance. It is suitable for various harsh field environments!
It can be seen from the above scheme that the front-end camera transmits the video signal collected by the monitoring center of the forestry department at the back-end through the long-distance wifi image transmission module, and the monitoring center of the forestry headquarters watches the real-time monitoring video of the forest through the Internet. If you need to find a fire, you can quickly lock the location and put it out in time.
Since the transmission environment of the long-distance wifi image transmission module needs to be open and barrier-free, we can use the relay method to achieve the purpose of stable transmission of video signals. If wireless transmission projects are required, users can consult to configure equipment more reasonably and save investment costs. Our professional technical team will provide users with the most suitable solutions according to the specific site environment.
What problems should be paid attention to when connecting and debugging the long-distance wifi image transmission module, when using the wireless module to build a monitoring system, the connection and debugging are very important. The correct connection determines whether the wireless system can work normally, and the debugging process affects the transmission quality and stability of the real system. Therefore, these two links should be completed by professional and technical personnel. Today, let us understand the problems that are prone to occur in wireless connection and debugging and how to solve them?
Connection link:
1. First, we should connect the long-distance wifi image transmission module with the camera through POE. The network data input terminal is connected with the network camera. The powered port connects directly to the wireless.
2. After the long-distance wifi image transmission module is connected, if the local connection of the computer is often disconnected (red cross), sometimes the signal will be lost. This should happen because the network you are using has too many sources of interference nearby, causing the transmission to be interfered with.
Debug link:
1. For long-distance wifi image transmission module or intermittent connection, the reason may be that the antenna angle is incorrect, resulting in weak signal. In this case, the user needs to open the WEB interface of the receiving end, find the signal interface, and check the signal strength in the interface to adjust the angle of the antenna. With each adjustment, check to see if the value after the receiving point decreases. If the signal is not ideal after the angle of the receiving point is adjusted, the angle of the transmitting end should be adjusted.
2. The speed is low. In order to avoid this situation, the transmitter should be set to receive mode after installation, and use the transmitter to scan the surrounding signals. After scanning, find the strongest signal and try to avoid looking at its frequency (channel). For example, the strongest signal strength scanned - 60 frequency is 2412 (channel 1). Then don't use this frequency. You can choose 2312 or 2457 to avoid. (Amounts above -75 interfere generally do not pose a threat).
Although the construction steps of the long-distance wifi image transmission module system are very simple, in order to ensure the stability of the later transmission, professional technicians are still needed to complete the installation and debugging.
