H-710A HD mini wireless video transmission system, adopting COFDM (Coded Orthogonal Frequency Division Multiplexing, Coded Orthogonal Frequency Division Multiplexing) modulation technology, with a narrow transmission band, strong resistance to multipath interference ability and the ability to resist multipath fading, can realize the non-line-of-sight (NLOS), high-speed real-time transmission high quality image movement situation.
System adopts h. 264 coding standard, the output HD1080P image quality, resolution of 1920 * 1080 (compatible with 1080 I, 720 p, 480 p and standard definition).
Widely used in military reconnaissance, border patrol, police JiZhen, aerial and air search and rescue of surveying and mapping, maritime law enforcement, the urban management enforcement, press close to visit, such as health and epidemic prevention or emergency command, unmanned vehicle, unmanned ship, special robot, etc.
Apply to the scene to monitor the car etc. Equipment xiaoke disguise do visit to obtain evidence, and the air volume flow chart, uav wireless image transmission
Advantages:
◦ machine is small in size, light weight
◦ easy to carry (hidden, camouflage)
◦ has a strong ability of anti-jamming and non line-of-sight diffraction
◦ wide voltage input DC7-16V
◦ input interface is rich: SDI/HDMI, CVBS (3.5 mm interface,2.5mm interface)
◦ good sharpness of HD1080P
◦ receiver/transmitter of the LCD display interface clear, make the human-computer interaction more easy and convenient
◦ diversity antenna, make the real-time image more clear fluid
