10W 20W HD COFDM Video Transmitter With HDMI H265 H264 Encoder Support OEM
Key Features:
Overview:
HCT531 wireless COFDM 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 COFDM transmitter 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.

Frequently Asked Questions:
Q1. Does your 10 watts/ 20 watts COFDM Wireless video transmitter support changing frequency to be 1.2G/ 1.4G?
A:The transmitter frequency can be 160MHz~2700MHz, but our COFDM wireless receiver only supports 170~860MHz, if you want 1.2G or 1.4G,then need to intall a frequency down converter at the receiver end.
Q2. Does this COFDM wireless video transmitter support SDI video input?
A: Yes, our COFDM wireless video transmitters support HDMI, SDI, CVBS AV, IP Ethernet RJ45 and AHD video input, please just let us know what video type you prefer.
Q3. What's the max distance for the 10W PA transmitter?
A: For UAV application, the transmission range is about 100km, the height of UAV is about 500 meters, and put the antennas of receiver as high as possible.
Q4. Does your transmitter and receiver support standard DVB-T protocol?
A: Yes, it supports 3 working modes:
Q5.I want a set of wireless video transmitter and receiver to transmit two channels at the same time, one HDMI video and one audio.
A: Our COFDM weireless transmitters support one HDMI and one auxiliary CVBS audio and video input at the same time. Currently, it can only support one sound source, which can be modified by our parameter configuration board, to choose HDMI sound or CVBS sound.
