10W 20W COFDM HD Transmitter For Two Videos Input Long Range Transmission
Key Features:
Overview:
HCT531 COFDM HD transmitter is designed for use with HD or SD cameras, it's a superior miniature wireless video transmitter designed for capturing real time, high quality videos from Point of View Cameras, UAV,UGV,Body Cams,Concealments, and sport cameras. The transmitter has HDMI or AV inputs, adopts COFDM modulation technology and H.264/H.265 encoding to achieve low latency video audio transmission in high-speed motion and NLOS (none line of sight) conditions. The HCT531 wireless video transmitter delivers a power output up to 10W or 20W, housed in a small metal case, weight is less than 910 grams, providing long range, reliable HD wirless 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 range is 160MHz~2700MHz, but our COFDM wireless receiver only supports 170~860MHz, so if you want 1.2G or 1.4G, We suggest to intall a frequency down converter at the receiver end.
Q2. Does the wireless video transmitter support SDI video input?
A: Yes, We have different kinds of 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. We will introduce them to you accordingly.
Q3. What's the max distance for the 10W PA transmitter?
A: For UAV application, the transmission range is about 100km, The flight altitude of the UAV Drone 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.
