Visão geral do produto

o COFDM Transmitter Wireless Video Modulator is a professional-grade digital video and audio transmission solution designed to meet the demands of modern broadcasting, Reconhecimento de UAV, monitoramento de segurança, and mobile communications. By adopting advanced COFDM (Multiplexação por divisão de frequência ortogonal codificada) modulação e MPEG-2/H.264 video compression, this system delivers estável, em tempo real, e transmissão de vídeo de alta qualidade over long distances — even in sem linha de visão (NLOS) environments or under complex interference conditions.

Unlike conventional analog wireless systems or narrowband digital transmitters, this COFDM wireless solution maintains consistent performance in environments affected by multipath reflections, urban obstacles, or high-speed movement. Suporta ambos HDMI e HD-SDI video inputs, making it versatile enough for professional cameras, UAV payloads, or mobile broadcast setups. On the receiving side, multiple output interfaces such as HDMI, USB, and Wi-Fi ensure compatibility with Android/iOS devices, recording equipment, or live monitoring stations.

The system is available in ultra-compact PCB module versions for OEM integration into UAVs, handheld devices, or embedded platforms. With transmitter modules weighing less than 20g and receiver modules under 25g, the COFDM transmitter is ideally suited for applications where weight and space are critical factors. Despite its size, ele fornece >2 km transmission distance (standard ISM 900 Banda MHz), latency as low as 30 EM, and outstanding resistance to interference.

This product line offers a full spectrum of deployment options — from lightweight UAV micro-modules to rugged housings for ground-based broadcasting. Whether for aerial video downlink, vigilância secreta, mobile news gathering, or wireless event broadcasting, the COFDM Wireless Video Modulator provides the ideal balance of performance, confiabilidade, and mobility.
