Only 15ms Low Delay Wireless UAV Video Transmitter Ultra-miniature HD Audio Video Transmitter 1080P


Specification Sheet




HD Video Transmitter Introduction:

The ST50HPT is an new design ultra-miniature TDD-COFDM digital video transmitter from SUNTOR. The most prominent of mini transmitter is of composite, High Definition Multimedia Interface and SDI video input formats.
With 4th generation COFDM, narrow-band, and H.264+H.265 encoder technology as its code, the small size and triple video ports HD transmitter sends high definition images ideal for establishing rugged wireless video links in different environments. The small size and low consumption make the HD mini transmitter ideal for UAV/FPV and helicopter, enabling true long range HD video transmission.
