HCT531 COFDM Wireless Downlink Transmitter

HCT531 COFDM Wireless Downlink Transmitter

---10W/20W HD video COFDM wireless downlink transmitter with HDMI/ AV input interface

The HCT531 wireless digital video transmitter was designed for use with HD or SD cameras, it's a superior miniature wireless video transmitter designed to capture real-time, high-quality video from Point of View Cameras, UAV/UGV/Body Cams/Concealments, and sports cameras. The transmitter features HDMI or AV inputs with COFDM modulation technology and H.264/H.265 encoding that complete video audio transmission in high-speed motion and NLOS (none line of sight) conditions with low latency. The HCT531 delivers up to 10W or 20W of power in a small metal case weighing less than 910 grams, providing long range, reliable HD video transmission.

Features:

•    COFDM modulation and H.264/H.265 video compression;

•    Full HD resolution, 1080p/i @60fps;

•    Supports two channel videos at the same time(optional)

•    Great security by AES encryption;

•    Modular design and high integration;

•    Stable signal transfer in NLOS and high-speed motion;

•    Adjustable working frequency, band width, bitrates, RF power, etc.
