Alloy steel refers to steel with high strength and good chemical stability at high temperature. It includes two types of anti oxidation steel (or high temperature resistant steel) and hot steel. Anti oxidation steel generally requires good chemical stability, but the capability is limited. High temperature strength and the corresponding oxidation resistance of heat and strong steel are required. Heat-Resistance Steel is often used in the manufacture of boiler, steam turbine, power machinery, industrial furnace and aviation, petrochemical and other industrial sectors in the work of the high temperature parts. In addition to the requirements of high temperature strength and high temperature oxidation corrosion, sufficient toughness, good shaping and welding are also required according to the different use, as well as a certain organizational stability. In addition, some new low chromium nickel oxidation are also developed .

Wireless video surveillance system is a small-scale remote digital surveillance system. It can be used together with a network camera. It can be wired or wirelessly connected to a network. It is easy to install, and does not require users to configure additional computers and video recording equipment. The user can use a mobile phone or a computer as a monitoring terminal device to receive alarm information and view monitoring video anytime, anywhere. Due to its advantages of flexible wiring, short construction period, and low investment, it is widely used in places where cable monitoring is inconvenient. With the development, wireless remote video surveillance system is undoubtedly the future direction of development.
Outdoor large-scale monitoring system
Because of the large number of monitoring points and large video traffic, large-scale monitoring systems are usually fiber optic structures. And in order to ensure the robustness of the entire system, but also to use a distributed architecture. The entire area needs to be divided into different monitoring areas. In the monitoring area, wireless monitoring or wired/wireless hybrid monitoring can be used. Through wired or wireless access to the data of a single monitoring area to the backbone network, the entire system can have multiple storage and monitoring centers for redundancy backup, and a single monitoring area can also have a small monitoring center.
Temporary monitoring system
The monitoring center is relatively fixed and equipped with back-end systems such as matrix, storage systems, and monitors. The surveillance area consists of cameras, video servers, and wireless bridges. Due to the increasing number of IP network cameras, video servers and cameras can be replaced with IP network cameras.
Wireless monitoring focuses on wireless transmission equipment, ie wireless bridges. From the device selection point of view, for the case of no more than 9 monitoring points, 11n devices such as RD-W353CPE can be directly used for transmission. If there are a relatively large number of monitoring points, for example, more than 15 points, then 5.8 GHz RD-W355CPE should be used.
