30W high power cofdm 30km wireless transmitter
Introduction:
ST6200CZA-Z vehicle-mounted narrow-bandwidth wireless image real time transmission system(strict conformance with police department transmission frequency band requirement: 2MHz frequency band), it adopts COFDM modulation technology and combine with foreign advanced diversity reception technology. It has higher sensitivity, farther transmission distance and stronger anti-interference performance than 8MHz products. It is mostly used for NLOS or complicated working environment.
AV coding adopt MPEG-2 standard, definition reach to DVD resolution ratio(720*576@ PAL / 720*480@ NTSC). The advantage of the product includes clear image quality, good color performance and smooth image.
Main Features:
Used for long range av transmission. As it adopts 2MHz wireless frequency band, it has higher requirements about the coding stream rate. And it also reduces the channel rate, increase the sensitivity receiving limitation, with stable signals.
Vehicle-mounted equipment application:
Used in man to car ,man to control center. This equipment has transmit power and long transmit distance ,can do a wide range of mobile high definition image transmission, distance can up to 90km in line of sight.
Product advantages:
1. 2MHz wireless bandwidth transmission, DVD video image quality.
2. Dual AES encryption can be set manually
3.. It comes with display to show the parameters, adjustable parameters
4. Receiver has LCD display to show the Signal strength indication
5. Receiver has CVBS and digital HDMI output
6.. Only using 2MHz frequency bandwidth
7. Longer wireless transmission distance, about 1/3 longer than the 8MHz bandwidth products
8. High quality digital video processing, and H.264/MPEG-2 video encoder decoder.
9. Very low delay when encoding, about 300ms point to point
10. Transmit audio video stably when the equipment moving fast and with much interference.
11..Supports NLOS distance transmission
12.Transmission power:10-30w adjustable
13. With spatial diversity reception capability
14.Two receiver antennas, with stable signal and smooth video image
15.Can customize all kinds of product form
Product application:
This product has wide application, such as Public security, Fire control, traffic, Civildefense emergency, City management,Environment monitoring, Flood control,Electricity rescue,Railway rescue,Maritime law enforcement,Maritime surveillance inspections,Customs and Border Protection,Pier monitoring,Forest Fire,Oilfield theft,Military reconnaissance,living broadcast, and so on. It is suitable for urban area, seaborne, mountainous region and other complex environment high quality image mobile transmission.
Application mode:
Transmission path: TX~ communication command vehicle ~ local command centre ~ network to provinces and cities command centre. At the front end, workers carry the transmitter to transmit the site audio, video signals to communication command vehicle; Then, the communication command vehicle as repeater to extend the wireless signals to local command centre; Last, in the local command centre, customers can access one channel av signals into monitor to realize real time monitoring and control. For another av signals, it can be transmitted to all provinces and cities by MAN or WAN command centre. In the command centre, customers can also access the signals into PC to view av signals and record.
