Vehicle-mounted wireless mobile video transmitter

Fig

HD car mobile image transmission system transmitter

MV2025TJ20P-264

 

○ Broadcast-level audio and video coding quality, supporting multiple audio and video input modes

○ 19-inch standard chassis design, easy to connect and install with standard rack

○ Aluminum alloy casing, impact resistance, good heat dissipation

○ With image transmission encryption function, it can prevent others from receiving signals of the same frequency

○ Adopting COFDM modulation technology and H.264 image compression technology to ensure stable signal transmission and high-quality audio and video signals

○ It has the characteristics of non-line-of-sight (NLOS-NO LINE OF SIGHT) and transmission in sports
