Specification
Model: SG-TDD20
TDD-COFDM is our new NLOS(non-line of sight) two-way data transmission system and wireless mobile emergency communication private network, which is independent of telecom operators wireless network. Its confidentiality, security, mobile performance that is better than Telecom operators. Also is a fully transparent data encryption transmission emergency security network.
TDD-COFDM multiplexing technology to channel resources in time through time slot, frequency through a large number of sub carriers to flexibly allocated to multiple users, and in a single frequency to maximize the realization of multi user access. Channel into the AES128bit, and user manually customize key that strength to ensure the data encryption. System occupy relatively narrow-band air frequency(4/8MHz)and strong anti-multipath interference ability to overcome simulation technique and the high-speed mobile data transmission under multipath reflections and nuisance caused by occlusion, then achieved in a complex environment transfer: data packing form, audio and video data, serial asynchronous data, Miniature volume, precision design, lightweight and easy to carry that commonly used in short distance high speed wireless data transmission and on air long distance high speed wireless data transmission purposes.

- Q: Security monitoring project is not to build the division of electromechanical professional practice
- Mechanical and electrical (including weak), municipal professional good, mainly depends on your interest and ability.
- Q: I just do business, security monitoring project, I do not know how to live and run project, please predecessors generous with your criticism!!! Thank you
- I just graduated a year, enter the security also soon, oneself also engage in learning in the inside front side, also recruited a number of sales every street, but no effect, then I run slowly better.
- Q: Why security system is better than the Chiwei AI Tai?
- Or an electronic system or network that is assembled or integrated into subsystems by these systems.
- Q: What is the product code for security cameras?
- As well as the process of working out the original records and files to prevent the wrong coding, the basic requirement is to ensure the uniqueness of the commodity code. The following is some security camera commodity code, in the customs can query.
- Q: What is the quality standard of security monitoring products?
- Quality standard of security monitoring products:Relating to the technical standards and specifications (including the design standards and specifications, product standards and specifications, engineering standards and specifications, acceptance criteria and norms) must comply with the relevant laws and regulations of People's Republic of China, regulations, standards and technical specifications (but not limited to those listed):Code for design of cigarette factory (YC/T9-2006);Code for fire protection design of buildings (GB50016-2006);Standard for intelligent building design (GB/T50314-2006);Code for electrical design of civil buildings (JGJ16-2008);Code for engineering design of integrated wiring system (GB50311-2007).
- Q: What qualifications do you need for security?
- Security qualification mainly refers to the engineering qualification of security engineering. The application and standard of security intelligence is based on the security industry development situation and requirements, by China CSPIA (hereinafter called anxie) on self-discipline is one of the main form of enterprise file security project launched the qualification evaluation system.
- Q: General security monitoring, construction costs accounted for the total amount of equipment?
- 3., security monitoring, construction costs accounted for the total amount of equipment, it is difficult to negotiate, ranging from 15%----20% consultationTax, if the customer wants to vote, the total equipment price plus 4.83% of the construction costFinally, the total equipment, construction costs, taxes together, that is, the total price
