Mobile communications enters security: industry technology will break new ground
Mobile Internet Brings New Opportunities for Security Before the release of 3G licenses, operators dominated online video surveillance platforms such as “Global Eye†and “Wide Visionâ€. At that time, video surveillance platform providers as operators were mostly large players in the communications industry. For example, Huawei, ZTE, and Bell, and the front-end equipment and video coding equipment vendors are mostly mainstream security manufacturers in the industry, such as Hai Kang and Dahua.
Among them, the construction of cloud-based video service operation services falls naturally on the shoulders of communication operators. Currently, China Unicom and China Telecom should do a better job among operators.
The operation services of the video service are implemented to cover mobile terminals such as traditional PCs, mobile phones/Pad/MIDs, and the operators have natural advantages. First of all, it has powerful advanced network communication resources, a large group of customer groups, and a complete operating system, in which China Unicom's network advantages in the 3G field further highlights the capabilities of mobile video applications. Second, although traditional security practitioners have struggled in the traditional security market for many years, they are not familiar with the security platform construction, operation support, and sales system in the carrier system.
With the advent of the mobile Internet era, more security equipment manufacturers are now provided with more opportunities. At present, the basic construction of the core network video surveillance platform for operators in various provinces has been completed. The introduction of new services such as high-definition is basically escalating on the original platform. Expansion, then focus on the operator's sales system and operational support system.
The operation support system is the core of the operator's business. It mainly includes platform deployment, core network element interconnection, and support for the account and billing system. The video operation platform deployed through this system can ensure that corporate customers can use a certain method of renting through monthly packages. Billing mobile phone number to achieve business deduction and billing settlement.
Group customer sales system is different from common personal business. According to the type, it can be generally divided into large industry customers and small and medium-sized enterprises in the operator system. Among them, industry large-account managers are generally located in municipal companies and provincial companies and are responsible for sales of small and medium-sized enterprises. The client managers are more distributed in each sales department (different from the concept of business offices) or district and county branches. The broad classification of industry customers among group customers is as follows:
Financial certificates: banking, securities, insurance, etc.; politicians: government departments or military; large enterprises: mainly large manufacturing companies or well-known enterprises in the province.
Operators divide grids according to administrative divisions and streets. The majority of SMEs in grids are small and medium-sized enterprises (SMEs) that operators refer to, and group account managers responsible for SME customers are also called grid managers.
The majority of SME customers hope that the initial investment is relatively low and there are not many customized requirements. Therefore, renting an existing mature platform is a better solution. Therefore, in order to better serve the majority of SME customers and some industry customers, the video service operation platform provided by operators needs to have the following specific characteristics and requirements:
Audience-oriented SME customers and some industry major customers, collectively referred to as group customers; business normative requirements are relatively high, corporate customers account and payment use follow the personal business support system, corporate customers can also be accepted to the business office; business fee model is flexible , You can self-machine installation, one-time purchase, or monthly package rental, and support different packages to be combined; operating service platform for the carrier-class platform, stability and performance requirements are very high; can support other mobile terminals other than PC terminals such as Access to smartphones, pads, etc. supports both IOS and Android operating systems.
The QCIF format is not very provincial. In order to meet the needs of most of the group customers, most of the operators' video service platforms provide common functions. However, depending on the customer group type of the cluster, the business will have different functional positioning and marketing priorities. :
For the professional market (clothing market, small commodity market, etc.): It is recommended to install 1 to 2 desktop network cameras and SD card local storage, and with 4MXDSL access; At the same time, for the "shopkeeper to see shop" customers, the main push security monitoring function, For "employees to see the store" customers, the store owner is highlighted for remote mobile management, mobile phone monitoring and shop functions;
For chain supermarkets, pharmacies, convenience stores, and cybercafes: It is recommended to install 2 to 3 fixed network cameras, mainly covering the areas such as shops and cashiers. Since these customers are mainly "employee-store-type" customers, they are prominent employees. Management, in-store security monitoring and traffic detection capabilities;
For hotels, KTVs, restaurants, properties, etc.: It is recommended to install more than 4 cameras. Considering the cost factor, analog cameras and DVS can be used to build. Access through the LAN, the main push employee remote management, in-store security monitoring, SMS alarm, long platform Storage and other functions;
Large-scale monitoring system: It is usually constructed separately through the integration of projects;
People and customers can also apply for and open this operating service platform to implement personal home security services.
The concept of standardized video operations within the carrier system is different from that of the traditional security market. The first is the non-project system. The core of the second platform is operations. Therefore, the standardization and boundary of services are clearly defined, while the equipment suppliers within the system are relatively less. Taking into account the platform's convenient access capabilities and customer coverage, the operator platform will generally consider binding 2-3 security equipment suppliers that provide mid- to low-end, high-end products in terms of equipment selection. It should be noted that the carrier's core platform support system (such as platform access, deployment, billing, auditing, billing, information transformation, and operation and maintenance capabilities) is concentrated in provincial companies, and therefore wants to enter the field of cooperation of operators. Security providers need to focus on technical and business cooperation with provincial companies.
With the rapid development of mobile Internet and smart terminals, the extension of security is expanding and the applicable fields are constantly expanding. It is believed that the security field will also face new opportunities brought by the mobile Internet as well as the Internet and IT sectors. challenge.
One of the most fascinating materials of our time is polycrystalline cubic boron nitride PCBN - the second hardest material after diamond. At CeramTec, PCBN is used as a cutting material from which indexable inserts are manufactured for machining.
PCBN is produced synthetically and is a "composite material" made of cubic boron nitride and a mostly ceramic binder phase. The ratio of cBN to binder content and the cBN grain size determine the application.
PCBN cutting materials are used in the machining of hard and/or highly abrasive workpiece materials. The high hardness and the extremely high hot hardness (up to temperatures above 1,000°C), the edge stability and inertness towards ferrous materials as well as the basically good chemical resistance give CBN cutting materials a high potential for use in machining. On the cutting material side, a distinction is made between high- and low-cBN cutting material grades.
PCBN (Polycrystalline Cubic Boron Nitride) blanks for cutting tools are composite ultrahard materials sintered by polycrystalline CBN and carbide alloy under ultra-high pressure and high temperature conditions. They combine the hardness, wear resistance, and thermal stability of CBN with the impact resistance and toughness of carbide alloy. PCBN blanks are highly suitable for cutting ferrous and non-ferrous metals with high hardness.
