Aperçu
le Émetteur sans fil COFDM est de qualité professionnelle, high-performance video transmission solution conçu pour aerial, mobile, and remote video applications. Utilizing Multiplexage par répartition orthogonale de la fréquence codée (COFDM) technologie, this system ensures robuste, real-time HD video transmission with minimal latency and strong resistance to interference caused by multipath propagation, obstacles, or high-speed movement.
Avec HDMI, IDS, 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 (LA) transmission while maintaining high-quality video clarity and stable frame rates even in hors ligne de vue (NLOS) environnements. Its compact and lightweight design makes it ideal for drones, drones, security vehicles, mobile news collection units, and field monitoring equipment.
Designed with advanced H.264 and MPEG-2 video compression, this transmitter guarantees lisse, 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, intervention d'urgence, diffusion en direct, and mobile surveillance.
