LA-6800QZ SD Car COFDM Wireless Video Transmission System

Main Products: wireless monitoring, wireless monitoring equipment, wireless video transmission, wireless monitoring system, wireless video monitoring

LA-6800QZ standard definition shipboard wireless video transmission system adopts COFDM (Coded Orthogonal Frequency Division Multiplexing) modulation technology. It has a narrow transmission frequency band and strong anti-multipath interference capability. Distance (NLOS), real-time transmission of high-quality images under high-speed motion. The system adopts the MPG-2 digital video coding standard, and outputs DVD image quality with a resolution of 720 * 576 @ PAL / 720 * 480 @ NTSC, with clear and smooth images.

Widely used in military reconnaissance, border defense patrol, public security (including fire protection, forest fire protection, traffic police), civil air defense emergency, water conservancy and flood prevention, environmental protection monitoring, power inspection, railway rescue, maritime law enforcement, urban management law enforcement, construction site / wharf / oil field monitoring, television broadcast , Health and epidemic prevention or emergency command. It is suitable for real-time mobile video transmission in urban, sea, mountain and other complex geographical environments.

Applicable to mobile command vehicle ~ command center. Can also be used as a relay device to make the transmission distance longer.


Note: The appearance of this product needs special customization, and some functions can also be customized according to the actual situation!



■ Synchronous input of audio and video signals, omnidirectional antenna transmission

■ Non-line-of-sight (NLOS) \ High-speed motion transmission

■ Built-in air-cooled heat dissipation device to solve the heating problem of high-power equipment

■ Using OFDM modulation technology and MPEG-2 image compression technology

■ The straight line transmission distance is not less than 100km under the sight condition, and 3-50 km under the non-sight condition
