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

○ ABS image transmission encryption function can prevent others from receiving the same frequency signal

○ 6/7 / 8MHz, 1.25 / 2.5 MHz, multiple bandwidth output settings

○ Working frequency is adjustable, that is, it can be set within the specified frequency range

○ Adopt COFDM modulation technology and MPEG-2 / MPEG-4 image compression technology to ensure stable signal transmission and high-quality audio and video signals

○ Matching receiver: MV2025RJ7-A / 1080i; MV2025RH7-AJK / 1080i
