1W COFDM FPV Transmitter Receiver Video Transmitter Receiver w/ Ultra-low Latency for FPV Drones

Advantages (1W Version):
* COFDM digital wireless video transmission system
* Dedicated to FPV drones
* Long range and no delay (ultra-low latency)
* 128-bit encryption

Features:
* Highly integrated, modular and combined design
* It adopts COFDM modulation technology and H.265 coding technology
* It can simultaneously transmit one-way analog video signal and one one-way data with a maximum rate of 230400bps
* Low latency: end-to-end latency is at least 120ms
* All-round communication and extremely strong diffraction performance
* High-speed inter-travel communication
* The heat sink type aluminum casing of the the transmitter is shockproof and impact-resistant
* For non-line-of-sight (NLOS) mobile transmission and ground transmission, when the transmission and reception height is 3 meters, the transmission distance is not less than 3KM. And the transmission distance under the visual condition is not less than 30KM (there is slight non-co-channel electromagnetic interference), and the longest distance can reach more than 100KM (the electromagnetic environment is clean)
* The maximum moving speed can reach 600KM/h (in tests)
* The receiver video signal is synchronously output in HD HDMI-compatible 1080P (multi-format optional), and the standard definition output DVD image quality
* The receiver supports recording and backing up video
* 128-bit AES encryption and decryption

Applications:
* Due to its extremely strong diffraction performance and high anti-interference ability of narrow band, this product is especially suitable for video transmission of low-altitude and high-speed UAVs and unmanned ground equipment.
