1~5km Portable COFDM Wireless Video Transmitter with Military Grade
Level
Description:
DS-HDT1W is a micro new customized HD COFDM video
transmitter,specially designed for UAV,UGV and body-worn use. It is
a rugged,miniature,high definition digital video transmitter ideal
for long range video and data control purpose. DS-HDS1000A
transmitter is in full hd resolution with HDMI input for HDMI
camcorder connection, and data serial port(RS485/RS232/TTL) for
one-way data control.
The increased compression and efficiency of the H.264 encoder
offers users additional range with the added benefit of small
size,low latency and low power consumption. In particular, COFDM
provides robust,secure and reliable video transmission over long
ranges. And its great security of the transmission can be ensured
using the optional internal AES user defined encryption from end to
end.
For application scenarios with mountainous terrain and vegetation
coverage in forested areas, fixed nodes are deployed at commanding
or relatively high points in forested mountains. They can also be
co-located with public network base stations, which not only
facilitates power supply installation, but also enables
interconnection with the public network. The equipment does not
require personnel to be on duty. Through self-organized
interconnection and multi-hop relay methods, the adverse factors of
mountainous areas blocking wireless signals are transformed into
commanding heights for relay and forwarding, thereby extending
communication distance, expanding coverage, reducing monitoring
blind spots, and reducing construction investment. The fire danger
data and image information collected by each node equipment can be
transmitted back to the forest management command center or
satellite communication command vehicle in real time around the
clock. It can also be transmitted back to the remote command center
through the 3G/4G public network to facilitate the commander's
timely viewing. , scientific analysis.
The vehicle-mounted radio is installed on the satellite
communication command vehicle and patrol vehicle, which facilitates
the flexible networking of "communication in silence" and
"communication in motion" with the fixed platform at commanding
heights and rangers. It can not only serve as a front-line command
center to quickly enter the forest area, facilitate information
collection, patrol monitoring and command and dispatch, and provide
wireless network support for surrounding rangers; it can also
interconnect with satellite communication systems to transmit
front-end on-site information back as soon as possible. The
back-end monitoring and command center can predict, respond to and
control on-site fires in a timely manner.
The individual soldier platform is small and portable, with strong
battery life, making it easy for rangers to carry on foot.
Especially when the fixed platform at the commanding heights cannot
effectively cover the area or the vehicle-mounted platform cannot
reach the area, it can go deep into the forest area to perform
front-line emergency tasks, which is convenient for communicating
with surrounding vehicles. Real-time voice communication between
commanders and other rangers enables efficient local collaboration;
it can also transmit video images of fire conditions collected
within the forest area as promptly as possible to provide
comprehensive and clear on-site images to commanders at all levels.
By carrying image collection and airborne self-organizing network
node equipment on drones into the air, it is maneuverable,
efficient, and quickly accessible, which can further expand
wireless coverage, reduce coverage blind spots, and improve video
return quality; it can also integrate aerial mobile surveillance It
is organically combined with ground fixed monitoring and
complements its advantages to form a ground-to-air
"three-dimensional" monitoring network, which effectively increases
the visual range of the monitoring area and reduces monitoring
blind spots, while better realizing fire detection, prediction and
real-time monitoring.
