H-620AHigh Definition Vehicle-mounted TypeBidirectional voice/ Data Wireless VideoTransmission system, usingCOFDM(Coded Orthogonal Frequency Division Multiplexing:CodeOrthogonal Frequency Division Multiplexing (OFDM) modulation technology, with narrow transmission bandwidth and strong anti-multipath interference ability, can achieve non-line-of-sight (NLOS), real-time transmission of high-quality images in high-speed motion.Have two-way intercommunication/ Data transmission function makes field command more flexible.
System adoptionH.264 Digital Video Coding Standard, Outputhigh definitionHD1080P quality, resolution 1920*1080 (down)compatible1080I, 720P, 480P and standard clearance.
It is widely used in military reconnaissance, border patrol, public security (including fire control, forest fire control, traffic police), civil air defense emergency, water conservancy flood control, environmental protection monitoring, electric power patrol, railway emergency, maritime law enforcement, urban management law enforcement, etc.Construction site/ Wharf/oil field monitoring, television broadcasting, health and epidemic prevention or emergency command. Video Suitable for Urban Area, Sea, Mountainous Area and Other Complex Geographical EnvironmentReal-time mobile transmission.
It is suitable for mobile monitoring vehicle to command center. It can also be used as a relay device to make the transmission distance farther.
