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:
- Standard DVB-T protocol, normal DVB-T can get the transmitter signal, no encryption and decrryption function.
- COFDM protocol, support TX encryption and RX decryption, support H265 and H264 encoding, but no super low latency.
- COFDM low latency protocol, H264 encoding with low latency, support TX encryption and RX decryption function,
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.
