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:Do you have a safety monitoring system?
- Yes, all exhibitions are sold with Jing equipment. The general public can buy it at an exhibition.It is equipped with cameras and microphones, designed as tie clips, glasses, buttons, like samples.Video storage and batteries are designed to be radio sized and can be attached to a belt.
- Q:Some students introduced me to do safety monitoring, should be a technician, responsible for installation and maintenance, I do not know, well, how about the salary? Any promotion? What's the future? Please advise!!But it seems like less vacation, only two days a month. Also, the job is busy and seems to be installing everywhere
- Do you do technology is behind the system engineer, if it is more interesting for your feeling, can be extended to consider the contact surface, research practice of other subsystems of the weak, and eventually become a professional engineer, technical stability. But personal feeling is still better sales, space and prospects for development better.
- Q:What's the difference between security and surveillance?
- The scope of security is relatively large, out of surveillance, there are perimeter alarm, intrusion detection systems
- Q:Begged, "security monitoring" for the record, where do you need to go? What materials need to be prepared?
- System design, construction and maintenance qualification numberThe reporting unit trial system project in time, should be attached to the following materials (A4 size are used):(1) the letter of entrustment or the design task book of the system construction unit;(two) contract or agreement (copy);
- Q:Does security monitoring belong to electronic products? What kind of goods does he belong to?
- Sell separately, as an electronic product.In the project, do the weak electricity equipment or security equipment.
- Q:Want to open a small security Monitor Company, but heard people say no qualifications, no project, no one assured me that the project to do, consulting the qualifications for information
- Own relationship, you can receive the project, operation control standard. First, you can call someone else's company
- 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
- You can not start the business, first with the line related to do a few years, and so on to find a routine, there are contacts and experience, and it is not too late! Now you go blind, and there's no sense of direction
- Q:Security monitoring sales method，Security monitoring sales, first of all, they will install,
- Introduce security products, to highlight product characteristics, as well as other brands of security products compared to advantages.
- Q:It's learning technology. I'd like to know what it's about
- Outside, in order to quickly grasp the relevant knowledge, it is best to professional website (such as 1000 forum, public safety net) to look at others' questions and answers, and then to a security company to work, from the grassroots level, so you will quickly become a technical personnel security industry.Good luck！AI security, security industry 12 years experience.Yes, please. Thank you!
- Q:What are the sales methods of security engineering?
- Introduce security products, to highlight product characteristics, as well as other brands of security products compared to advantages.
