Introduction
According to statistics from the State Forestry Administration, an average of more than 10,000 forest fires occur in China every year, and the burned forest area accounts for about 5%to 8% of the country's forest area. Forest fires are sudden and random and can cause huge losses in a short period of time. Therefore, rapid detection and extinguishing of forest fires has become the top priority of forest fire prevention.
Once a fire occurs, firefighting measures must be taken very quickly. Whether the firefighting is timely and whether the decision-making is appropriate, the most important thing is whether the fire point is discovered in time. However, the forest area is huge and the terrain is complex, making it difficult for traditional wired monitoring solutions. Deployment, wireless video monitoring system have become the preferred choice for fire monitoring in forest areas, which is an industry trend.

Background
The environment in forest areas is complex, blocked by mountains and woods, and requires long transmission distances, reducing the number of sites, which poses great challenges to wireless transmission solutions.
The Long-distance wireless video transmission solution launched by IWAVE has the characteristics of strong anti-interference ability, strong non-line-of-sight (NLOS) transmission capability, low power consumption, and high protection level, and supports point-to-point, point-to-multipoint, MESH networking and other transmission methods. Flexible networking can be achieved.
Solution
For forest fire prevention wireless transmission, IWAVE 's outdoor wireless video transmission radio has the characteristics of stability, strong anti-interference, large bandwidth, and stable transmission rate .
In general forest fire prevention wireless solutions, the monitoring center from the front-end monitoring location is blocked by trees, so it needs to be transmitted through relay nodes. The video and images at the front-end site are transmitted to the relay through FD-6170FT, and then The relay radio transmits various front-end video and image signals to the back-end monitoring center.
The 4 monitoring points are distributed on a circle with a radius of about 25km from the monitoring center.
Since there are many trees in the forest area and there are mountains blocking it, wiring is inconvenient and the environment is complex, so a wireless video transmission solution is the best choice.

Solution's Description
4 monitoring points, each monitoring point is about 25 KM away from the monitoring center;
In order to ensure the stability of transmission in complex environments, a two-section transmission method is adopted. The transmission from each monitoring point to the monitoring center is divided intoRange A and Range B. The monitoring point in A Range is to the relay point, and the monitoring point in segment B is to the monitoring center;
Bandwidth and Distance:
Range A transmission distance is 10~15Km, transmission bandwidth is 30Mbps;
Range B transmission distance is 10~15KM, transmission bandwidth is 30Mbps, depending on the specific environment;
Monitoring Point: consists of an FD-6710T transmitter, IP camera, solar power supply system and pole components;
Relay Node: The FD-6710T transmitter and receiver are installed back-to-back for wireless relay transmission;
Monitoring Center: composed of an FD-6710T receiver and video monitoring and storage related equipment;
Power supply: 24V 1000W solar power supply system, the power consumption of the communication equipment is 30W;
Antenna:FD-6710FT transmitter uses 10dbi omnidirectional antenna, and the receiver uses 10dbi omnidirectional antenna;

Conclusion
The forest fire prevention wireless video monitoring and transmission system is a forest fire prevention digital and networked remote wireless monitoring project. It centers on forest scene image collection and uses remote transmission equipment as the transmission platform. It combines digital image processing technology,wireless transmission technology,and wireless communication technology. Comprehensively used in forest fire monitoring and forest resource management, it can monitor a wide range of forest targets with high-definition images all-weather, all-round, and long-distance, and transmit large-area forest scenes to fire monitoring in real time through video and images. Center to realize long-distance centralized monitoring of fire prevention personnel indoors and outdoors;
Moreover, while monitoring forest fire prevention, the system can also monitor forest resources, forest pests and diseases, and wild animals. It can even be used for vegetation protection and tree monitoring. Illegal loggers can be discovered through image recording, and the video data can be used as a basis for punishment. .
Therefore, remote video monitoring systems are widely used in forest protection work.
