IP66 man-portable long range 30km COFDM full HD wireless system
Introduction:
The Knapsack Digital Wireless Video Transmitter adopts the latest
technologies of COFDM modulation and MPEG-2 image compression that
enables good NLOS (Non line-of -sight) transmission with DVD
quality video. The transmitter is compact size with power amplifier
for longer-range transmission. This system has been widely used in
many fields such as: Forces, First Responders, Security Services,
Fire Services, Port Security, Homeland Security, Traffic
Management, Technical Support Units, Special Forces, Command and
Control Posts, Airport, Border Control, Major Incident Support.
Suitable for extremely high image quality requirements, sector
institutions be replaced HD and SD milestone products. New digital
video coding standard H.264 high performance compression, clarity
to achieve full HD1080P HD picture quality, resolution (1080I,
720P, 480P and 1920*1080 compatibility and SD).
Main Features:
- Lithium battery for power supply
- Convenient to be carried and installed
- COFDM modulation and MPEG-2 video compression
- Firm enclosure with built-in cooling fans, waterproof and
shockproof
- Protection standards: IP66, Dustproof, rainproof design
- Modular design and highly integrated
- Good transmission with high definition image and stereo audio
- Adjustable working frequency, LCD board displays the working
frequency
- Stable transmission in NLOS(non line-of-sight)and high speed mobile
conditions.
- The transmission range is more than 30km in LOS (line-of-sight)
environment
Application:
Mainly transfer way is individual soldier~Car~Control
center~Internet to different city control center.
By front-end staff carry launches equipment will transfer the audio
and video to communications command car; communications command car
as repeater put wireless signal extends to local command center;
local command center directly transfer video signal access monitor
for real-time monitoring and debugging command, another way through
city domain network or Wan transmission to national provinces
command Center; command center can directly transfer video signal
access monitor for real-time monitoring, while can using network
monitoring, Connect PC to browse audio and video.
