With the rapid development of my country's economy, commercial real estate and office buildings are also developing vigorously. With the improvement of the construction of industrial parks and the introduction of the concept of creative parks, the construction and management mode of industrial parks is also changing. The needs of companies and properties for the security monitoring of the park, the video surveillance of the creative park has been paid more and more attention, and it is also one of the standards of the park's own construction. A perfect video surveillance system in the park can greatly enhance the safety and management of the park, stop some hidden dangers in production safety, key areas and illegal acts before they occur, and ensure the traceability of the incident. At the same time, inspection manpower and property management costs can be greatly reduced. In addition, the video surveillance system of the park can also be connected to the public security system network to comprehensively improve the public safety of the industrial park.
Security video surveillance can be seen everywhere in modern life. It can be seen everywhere in urban road intersections, highways, government agencies, enterprises, tourist attractions and other places, but most of them are based on traditional optical fiber and video cables to transmit analog video. signal, but also has some inherent limitations and disadvantages. With the advancement of technology, the wireless network digital monitoring system is relatively advanced at present. Compared with traditional monitoring systems, digital network monitoring using long-distance wireless wifi module wireless local area network technology transmission has more advantages. Corresponding to the traditional wired analog transmission, the wireless transmission monitoring of the long-distance wireless wifi module has many advantages.
Advantages of wireless transmission:
1. The wireless network transmission technology avoids the digging of cable trenches and overhead wires in wired construction.
2. Improve the distance of video transmission, the long-distance wireless wifi module wireless transmission can reach 20 kilometers, but the use of twisted pair connection has a limit of 100 meters, and the cost of optical fiber is too high.
3. The wireless network transmission is not affected by the terrain, it is easy to set up, flexible to expand, and can flexibly add or move monitoring points according to needs, and the troubleshooting is simple.
4. High security of wireless transmission to prevent illegal user access.
5. The long-distance wireless wifi module wireless transmission technology transmission technology avoids the impact on the owner's work during the construction process, such as the impact of trenching lines on community work, traffic impact, construction noise interference on life, etc.
6. Software and hardware maintenance is simple, safe and convenient;
7. The wireless network is easy to expand, and the maintenance cost is low. Compared with wired cables such as twisted pair and optical fibers, the transmission is farther, and it is safe and reliable.
According to the on-site investigation and analysis of the construction of the wireless transmission system in the park, we know that:
1. Environment introduction:
There are 30 buildings in the industrial park and one security booth. Among them, there are 19 factories. Buildings A1-A are four stories high, and there are 8 dormitory buildings (Building B1-B5, Building C1-Building C3). In order to facilitate the unified management of the park, it is now required to install 5 long-distance wireless wifi modules in each building. Cameras, A1 as the monitoring center, the park distance is 300-900 meters, the height of the workshop is unified to four floors, and the height of the dormitory is unified to seven floors. The need for monitoring itself uses a regional monitoring system. WLAN to achieve wireless transmission coverage monitoring management is a reasonable, cost-saving, economical, and ideal choice for park monitoring system services.
2. Design principles:
The design of this project follows the principles of advanced technology, complete functions, stable performance and cost savings. And comprehensively consider the construction principles, maintenance and operation factors, and will leave room for expansion for future development, expansion, renovation and other factors. The content of the system design is the complete and comprehensive system; the design scheme is scientific, reasonable and operable.
Main features of long-distance wireless wifi module:
1. Flexible wireless backbone design and layout advantages
2. Multi-module design supports single-mode/dual-mode/three-mode
3. Each long-distance wireless wifi module module can be set to 5G or 2.4G frequency band through software
4. Features of high-efficiency and large-bandwidth wireless backbone
5. Safe and effective bandwidth management design
6. Relay multi-point transfer with low power consumption and low delay function
7. Safe and flexible client connection management
8. Support encryption to ensure the confidentiality of data transmission
9. The long-distance wireless wifi module has Mesh network function (optional software function)
