Преглед

Най- COFDM безжичен трансмитер е професионален клас, висока производителност video transmission solution Проектиран за въздушен, Подвижен, и отдалечени видео приложения. Използвайки Кодирано ортогонално честотно мултиплексиране (COFDM) технология, Тази система гарантира здрав, HD видео предаване в реално време with minimal latency and strong resistance to interference caused by multipath propagation, препятствия, или движение с висока скорост.

С HDMI, SDI, and CVBS input compatibility, the transmitter supports a wide range of video sources, including action cameras, professional cameras, Дроновете, and mobile recording systems. The COFDM Wireless Transmitter is engineered for long-distance line-of-sight (THE) предаване while maintaining high-quality video clarity and stable frame rates even in извън линията на видимост (NLOS) среди. Its compact and lightweight design makes it ideal for БПЛА, Дроновете, security vehicles, mobile news collection units, and field monitoring equipment.

Designed with advanced H.264 and MPEG-2 video compression, this transmitter guarantees гладка, 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, аварийна реакция, излъчване на живо, and mobile surveillance.
