Two way Audio Vehicle Mounted Long Range COFDM Wireless Video
Transmitter Receiver
Introduction:
ST6222CZ-HD is a digital wireless video transmitter ,specially
dsigned for vehicle-mounted application, could transmit high
quality video signal in city or on sea where appears multipath
effect always.It can realise wide signal coverage without
directional antenna depend on its excellent "Diffract" ability .
It can simultaneously transmit one way image, one way Full-duplex
bidirectional audio and data.
Features:
- Full HD 1920*1080p resolution (support both 1080p/1080i at 60fps)
- COFDM modulation, H.264 video compression mode
- Built in with High Definition Multimedia Interface/HD-SDI and BNC
interfaces
- Support left/right stereo audio input and output
- Small in size and lightweight
- High RF power but in strong heat resistance capacity as dual
electric fans for increased cooling capacity
- 4/8MHz RF bandwidth, the working frequency will be displayed on the
LCD
New powerful HD COFDM video audio transmitter, it can up to 10-40W
RF power which support transmitting over a long distance.
Using the core technology 4th generation mobile communication COFDM
modulation and low delay full-HD 1080P technique that can transmit
high quality and stable image under the condition of fast moving or
many buildings as obstacles (NLOS)
Suitable for vehicles: cars, boat - boats, cars - a building,
ship-a base station, aircraft-a building/vehicle and more.
High-definition moving video signal transmission, the carrier
velocity greater than 450kph
Widely used in public security, armed , fire, rescue,
reconnaissance, field operations and other emergency communication
system.
