1~5W Man-pack narrow bandwidth SD COFDM video transmission system
Introduction:
ST6200DB-SD narrow bandwidth series wireless video transmission
system(Strict compliance with requirements of the public security
departments transmission frequency bandwidth: Only use 2MHz
bandwidth), using narrow bandwidth COFDM modulation techniques, and
combining diversity reception of foreign advanced technology,
comparing with the 8MHz equipments, this model is more sensitive,
stronger anti-interference, supports longer distance. It is very
suitable used in the complex environment; Audio video encoder uses
the H. 264/MPEG-2 standard, definition is up to DVD(720*576), clear
picture quality, bright colors, image smooth.
Advantages:
- 2 MHz narrow bandwidth, DVD video image quality.
- Dual AES encryption can be set manually
- With display to show the parameters, adjustable parameters
- The receiver has LCD display to show the Signal strength indication
- Only using 2MHz frequency bandwidth
- Longer wireless transmission distance, about 1/3 longer than the
8MHz bandwidth.
- Digital video process with high quality and video encoder decoder
is H. 264/MPEG-2.
- Very low delay when encoding, about 300ms point to point
- Transmit audio video stably when the equipment moving fast and with
much interference.
- Supports NLOS distance transmission
- Transmission power: 1-5w adjustable
- With spatial diversity reception capability
- Small size, light weight, very convenient to carry and install.
Applications:
The product is widely applied to a lot of industries, likes: Public
Policing, Fire&Security, Air Defense, &Guard, Smash
Smuggling, TV Broadcasting, Environment Protection, Maritime
Affairs, Large Mine, High Security Surveillance. And also applied
to any rugged terrains where there is no wired cable link for
audio,video, datas transmission: Mountain, Forest, Countryside,
Desert, River, Island, Oil Field, Large Mine, Maritime, Spacial,
Firing, Earthquake, Riot etc
