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.


Wireless rf Ethernet Transceiver TDD-COFDM Full Duplex



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: 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 are the most profitable products in the security industry?
Introduction of the most profitable products in security industry1. system integration, including software and hardware. System integration is a powerful company, in this case, describe the extent of its profits, and then a project to live three years. That is, a company that provides solutions.2., there are wireless alarm products, the market is broad, high degree of customer acceptance, you can make the cost recovery in three months, you can enter a high return within a year.
Q: How do security control engineers get it?
Security system integration engineers and security system integration project manager, students complete the course, by the Ministry of information industry electronic Talent Exchange Center awarded the national information security system integration project "engineer" technical certificate and the Ministry of human resources and social security issued by the "653 project" "security system integration engineer security system integration project manager certificate". Certificates can be used as an important basis for professional technicians to employ, hold, grade and promote their positions. Certificate holders will be included in the national information engineer talent pool for enterprises and institutions website inquiries.
Q: What are the security devices?
First of all, security systems generally think of monitoring, anti-theft alarmSecurity includes seven industries:1. monitoring2. guard against theft3. building intercom
Q: What are the functions of security decoder, the main function and principle?
The pan head decoder refers to a pan head and a lens controller. Generally, the lens (camera) is mounted on the pan head, and the pan head can rotate up, down, left and right. The lens can zoom in and out (zoom), focus, change the aperture size and so on.
Q: How does the security monitoring system go through the line?
Throughout the construction process, timely notification of the process, the person in charge of various types of work to communicate, to identify problems immediately notify Party A, in other follow-up work before the start of the timely completion of the task of this type of work.If the installation is unshielded twisted pair, the docking site is not high enough to be earthed at the main slot connected to the cabinet.The specification of the slot is to confirm that the cross section of the slot remains 40% of the surplus to be expanded, and the cross section area of the over 5 types of twisted pair is 0.3 square centimeters.When installing the slot, attention should be paid to the isolation of the strong wire slot. The wiring system shall avoid parallel lines of 3 meters parallel to the strong line without shielding and distance less than 20cm. If it can not be avoided, the line slot shall be shielded and isolated. The cable line into the furniture is made up of the nearest ceiling line along the partition wall to the ground, and from the ground boring trough and the buried pipe to the furniture partition.
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 outlook of the security industry?
Overview of 40 years' development of anti TechnologyAt the end of November 2011 I went to Shenzhen to participate in the Shenzhen Expo security, see a lot of companies hit the slogan "HD era", "security industry entered the era of high-definition" etc.. If it is to do some video surveillance enterprises say it, but I saw a lot of media also said "this is followed in the HD exhibition theme" HD "era coming now is that there is something wrong. For a time, give the user an idea, as if now the security industry mainstream technology is "HD", the remaining problem is "HD era" has arrived, or will come, not yet determined.
Q: The main products of the company are facing the country, is a high-tech remote multiple HD monitoring equipment, the company has developed a patented product, the sales department is also just set up, so there is no experience, all the electronic city company let us run it again, the results were OK, find a lot of dealers, now the region is not running I want to recruit agents, in the country, but I was new, really do not know where to start, what are the sites for the release of our products (hardware and software security monitoring information)? And, in addition to the website information, is there any other way? Please master sales, e-commerce experience of the master, and master pointing ah, I thanked the!
SEO do security equipment, agents and a series of keywordsDirect search for an agentThrough its own advantages, grab other brands of agentsMore publicity, to create a network of word of mouth
Q: Security monitoring.The security monitoring platform often appear. How to deal with the phenomenon?
You say. In replays? If so, then your video settings are set to motion detection, and you go to the video settings instead of the timer settings.
