Wireless video transmitter is with standard 19 inch 2U dimension appearance and suitable for fixed installation.
Wireless transmitters ST6220CZ-SD supports mobile images, audio, video transmission.
NLOS Portable COFDM Long Range Wireless Video Transmitter performs well PTP (point to point) audio video transmission.


Long Range Vehicle Video Transmitter (ST6220CZ-SD) can transmit up to 50km LOS long range and 20km NLOS long range with omni-directional antenna. It's suitable for Car to car,boat to boat,vehicle , boat, helicopter or drone to fixed station.


Device Advantage:

  • SD resolution 720*576.
  • H.264 high quality digital video processing&video encoding
  • The product shell is made of high quality stainless steel which is more solid and anti-deformation
  • Excellent anti-interference performance under complex electromagnetic condition.
  • One-way picture,one/two way voice,reverse control cloud deck function are available.
  • The LOS transmitter range can reach 50km when worked with omni high gain antenna.
  • Space diversity reception capability.
  • Can stably transmitter video&audio signal under the condition of high-speed mobile and multipath interference.


COFDM vehicle-mounted wireless video transmitter,can work in both fixed and mobile applications.It can transmit audio video in the NLOS(none line of sight) and fast-moving mobile environment.


ST6220CZ series are a digital wireless video transmission system, which can transmit stable video image in build-up city and serious multipath effect such as sea surface. It has good diffraction ability and penetrating building ability. Could adapt to urban, mountain land and movement environment very well.
