A polycrystalline novel silicate material obtained by crystallizing glass under the action of a catalyst or a nucleating agent, is a dense, nonporous, homogeneous mixture of a crystalline phase and a residual glass phase. Generally, the size of the crystal can range from nanometer to micrometer, and the number of crystals can reach 50% to 90%. Has high mechanical strength, low electrical conductivity, high dielectric constant, good machinability, chemical resistance, thermal stability and so on. These properties depend on the type and amount of crystals, as well as the composition and properties of the remaining glass phase, and are closely related to the crystallization conditions and the like. According to different nucleation or crystallization treatment, it is divided into photosensitive and heat-sensitive glass-ceramics. Can be used to make circuit boards, charge storage tubes, screens for photomultiplier tubes, missile warheads, radomes, bearings, pumps, reactor neutron absorbing materials, insulating pillars, etc. Machinable Glass Ceramic Bar,Machinable Ceramic Flange,Glass Ceramic Bars,Machinable Glass Ceramic Bars Dongguan Haikun New Material Co., Ltd. , https://www.nitrideceramic.com
The so-called “intelligent†in the security industry means that the system can automatically detect and identify abnormal conditions in the monitoring screen without human intervention, and can make pre-alarms in case of abnormalities. Because intelligent security monitoring systems can better meet the needs of people for monitoring security, in recent years, domestic and foreign visionary security companies and security monitoring companies with research and development capabilities have all invested in research and development. Foreign security monitoring systems or product suppliers continue to introduce intelligent products to the domestic market, as well as the emergence of domestic smart security monitoring systems or products. This brings surprises to the security industry and also makes many people in the industry feel extra confused. Can their smart video analytics work? Under what circumstances? Can we meet different levels of security needs on different occasions? Can we provide people with the greatest safety benefits and truly ensure safety? How does the security monitoring system be intelligent? Is there any level of intelligence? How can security engineering companies apply these products to security monitoring and control projects? Therefore, in addition to having a clear understanding of the level of intelligence in intelligent security monitoring system products, it is also necessary to conduct an intelligent assessment of such products.
In general, product suppliers, based on the principle of pursuing their own maximum economic efficiency, often unrealistically exaggerate their own products. However, users of security engineering companies and other users are not very clear about the intelligence of new products, and they have little understanding of the product's security benefits. If they are not evaluated, many systems and equipment that are put into use will not meet actual security requirements. The situation has even become a kind of decoration in the process of construction. This is not only a huge waste of investment for users, but more importantly, it does not meet the security needs.
If the user can intelligently evaluate the security monitoring system products used, or if these products are evaluated by an authoritative appraisal department, the results will be the same. In this way, security engineering companies can not only choose the most cost-effective and most appropriate intelligent product according to the user's security needs, so as to minimize the investment cost, but also can satisfy the user's security requirements to the maximum to achieve the best performance system. .
It can be seen from the above that it is very important to assess the level of intelligent standards for security monitoring systems or products. Such assessments need to be carried out to ensure the security requirements.
In recent years, a number of different levels of intelligent security monitoring systems or products have emerged at home and abroad, which can also be seen. Security monitoring systems are gradually being digitized and networked to become intelligent. However, do these intelligent security monitoring systems or products actually achieve advance warning/alarm through the identification of human and object anomalies? The security standards for security monitoring products have yet to be evaluated.
