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: Because I will not construction, not technology, I mean, after the shop, after receiving the project, the specific construction is not I go to the construction unit to do? What kind of professionals do you need inside your own store? Also, if it is to join other companies of the brand, shop when you need to go through what procedures, such as the public security departments for the record, business license and so on.
- 3. to the local industrial and commercial application form for industrial and commercial business license.4., then to the tax office tax registration certificate, now seems to have to do the industry code certificate, in the quality inspection bureau.
- Q: Installation process of security monitoring system
- 1, according to the design plan and site environment to do construction plan, preliminary determination trenching, open circuit, steel wire and so on need large equipment operation date. According to the site environment estimation manual, preliminary determination of construction materials and equipment arrival date. Pay attention to communicate with Party A.
- Q: Our company is a trading company, the main security monitoring products, but not simple sales, in fact, but also for customer design, installation, debugging to collect. The costs involved are: 1, do the server with the computer (6000 yuan), 2 meters (2900 yuan) 3, all kinds of materials, accessories and so on 4 installation staff wages, travel expenses (field installation) and so on, ask you master, this situation should be used and what subjects to cost? How is the carrying cost? How about the entries? All the scores are presented.
- If the building construction units, security monitoring equipment is used for the construction of residential or commercial housing sales, security monitoring equipment costs should be included in the cost of the project. ,Borrowing: engineering costCredit: bank deposits / cash in hand / payable
- Q: How many lines are there in the security monitoring system?
- The general monitoring point has power lines, video lines, 485 control lines, and the use of network cameras, the use of cable, power lines
- Q: Security engineer and security system integration engineer
- The security engineer is wider, including security product engineer, security system integration engineer, security engineer, design engineer, security system, security maintenance engineer, security engineer, security maintenance engineer, security management engineer, assistant engineer and other types of security.
- Q: How does the security monitoring system go through the line?
- Bright dark line details: bridge design is reasonable, to ensure the appropriate cable bending radius. When the upper and lower sides are around the other line grooves, the slope of the turn should be gentle, and the key point is that the cable at both ends will sag. After the force is applied, the cover plate can also be laid on the premise that the cable is not damaged.On line process is mainly control the tension, the tape reel cable, at least two suggestions to arrange for a worker to scroll in Guyed pole homemade, line end workers first pulled out a part of the cable from the scroll box for the pipeline in the pre, the other end of pre extraction. Pull out of the line can not be too much, to avoid entanglement with a plurality of lines on the ground around.
- 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
- Salaries should have been around 2000 at the start and 3000~4000 after technical proficiency.Installation monitoring equipment is within the scope of this work, belong to normal, need to pay attention to safety construction matters.
- Q: I would like to open a security monitoring store, you need to go through what procedures?
- Taxes are generally fixed monthly tax, according to the store to pay, a store is probably around 600, every month, thirty thousand of the start-up funds should be enough
- 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.
- 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.
