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.

- Let me answer you. The construction fee is 1. of the total equipment price10% without difficulty2. slightly difficult 12%
- Q:Who knows security monitoring common faults and solutions?
- It's OK to divide the equipment into cards. For example, the back of the surveillance system has a ripple of water
- Q:Do you have a safety monitoring system?
- Security monitoring system uses optical fiber, coaxial cable or microwave to transmit video signals in its closed loop, and from the camera to the image display and recording to form an independent and complete system. It can reflect the monitored object in real time, image and reality. It can replace the manual for long time monitoring in bad environment, and record it by video recorder. At the same time, the alarm system equipment for illegal invasion alarm.
