"big" and "small" applications for wireless video surveillance

With the development of wireless technology, wireless video surveillance is in a rapid development stage, and wireless transmission technologies such as WiFi, 3G, and microwave are also rapidly developing in a short period of time, and have been successfully applied in various fields of video surveillance. Compared with the wired monitoring system, the wireless video surveillance system makes up for the difficulty of wiring and has more flexible features. Let's take a closer look at the application of unlimited video surveillance.
Wireless video surveillance solution and application
The application of wireless transmission technology has overcome the traditional wired connection (coaxial cable, twisted pair, optical fiber, etc.), which is inconvenient in hardware connection, and has a three-dimensional access mode anytime and anywhere, which greatly facilitates the deployment of the access end. .
Based on the flexibility and maturity of wireless deployment, wireless technology has been successfully integrated into various scenarios in the surveillance industry;
1. Wireless monitoring of cash machines, bank tellers, supermarkets, factories, etc.;
2. Unattended monitoring of power transmission substations, power towers, and telecommunication base stations;
3. Monitoring of unmanned areas such as oil, drilling, and exploration;
4. Monitoring of moving targets of vehicles such as buses, taxis, and escorting vehicles;
5. Mountain forest and deep forest fire prevention monitoring;
6. Monitoring of water resources, rivers, lakes and other resources;
7. Monitoring along highways, along railway lines, bridges, tunnels, crossings, etc.;
8. Frontier defense coast and border monitoring;
9. Mobile patrol, mobile city patrol and other mobile point monitoring;
10. On-site and remote on-site monitoring and command of emergency response (emergency events including natural disasters, large events, emergencies, etc.);
11. Monitoring and application of monitoring and exercise for emergency response units.
"Small" in wireless video surveillance applications
Small-scale wireless monitoring, used in office places, factories, warehouses and other places, with fat APs and thin APs without access as the center, combined with the original wired network to achieve video transmission. The main scenes are: buildings that are not convenient for rewiring; if wired monitoring is used, it may cause damage to the original building, requiring trenching, embedding, etc., so it is not convenient to use traditional wired monitoring.
For small-scale monitoring, because there are fewer monitoring points, the video bandwidth of the access is relatively narrow. If the management requirements are not emphasized, the UAV network camera and NVR products with wireless access can be selected to design a more economical wireless. Video surveillance system.
"big" in wireless video surveillance applications
Wide-area, long-distance fixed-point monitoring applications for highways, forests, remote mountainous areas, oil fields, scenic areas, power, water conservancy, etc.; due to wide range, remote location, and difficulty in wiring, etc. It can better overcome the problems of wired deployment and reduce the initial input cost. Therefore, for the above types of monitoring scenarios, Dahua engineers recommend wireless monitoring, such as 3G, WLAN, microwave and other wireless technologies.
Generally, the number of wireless base stations can be determined according to the requirements of specific monitoring points and required bandwidth. Dahua engineers recommend two ways: 1. One deployment, comprehensive coverage of the required monitoring area, and only need to be deployed according to actual conditions. Corresponding monitoring equipment; 2, phased deployment, adding batch-by-batch according to monitoring points, synchronizing the construction of corresponding base stations, costing multiple inputs, more advantages than one-time deployment, and ensuring the application of new technologies in the later stage.
comment:
The application of wireless video surveillance has been very common, and its application solutions can be deeply penetrated into various fields. Whether it is a wide range or a small range, it can be seen that the wireless video surveillance application program has unparalleled superiority. In the future, with the wireless video surveillance Continuous development and the scope of application will continue to expand.
