visão global

o Transmissor sem fio COFDM é de nível profissional, alta performance video transmission solution projetado para aéreo, Móvel, e aplicativos de vídeo remotos. Utilizando Multiplexação por divisão de frequência ortogonal codificada (COFDM) tecnologia, Este sistema garante robusto, transmissão de vídeo HD em tempo real with minimal latency and strong resistance to interference caused by multipath propagation, obstáculos, or high-speed movement.

Com HDMI, SDI, and CVBS input compatibility, the transmitter supports a wide range of video sources, including action cameras, professional cameras, drones, and mobile recording systems. The COFDM Wireless Transmitter is engineered for long-distance line-of-sight (THE) transmissão while maintaining high-quality video clarity and stable frame rates even in sem linha de visão (NLOS) ambientes. Its compact and lightweight design makes it ideal for UAVs, drones, security vehicles, mobile news collection units, and field monitoring equipment.

Designed with advanced H.264 and MPEG-2 video compression, this transmitter guarantees suave, sharp images with natural colors, stable brightness, and minimal motion artifacts. The system is suitable for applications that demand real-time transmission with low latency, such as drone reconnaissance, resposta de emergência, transmissão ao vivo, and mobile surveillance.
