H-520AHigh List Bidirectional Voice and Video Transmission SystemUseCOFDM（Coded Orthogonal Frequency Division Multiplexing：CodeOrthogonal Frequency Division Multiplexing (OFDM) modulation technology has narrow transmission bandwidth, strong anti-multipath interference ability and anti-multipath fading ability. It can capture and transmit high-quality images in real-time under the condition of non-line-of-sight (NLOS) and high-speed motion. Two-way intercom function makes on-site 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/ Dock/oil field monitoring, television broadcasting, health and epidemic prevention or emergency command, unmanned vehicles, unmanned ships, special robots and other fields.
