vue d'ensemble

le WV-7012HD 7-inch Portable COFDM Receiver is a newly designed, poids léger, and compact digital video receiver built for demanding mobile and non-line-of-sight (NLOS) wireless transmission applications. Engineered with portability and user-friendliness in mind, this receiver integrates a 7-inch high-resolution TFT touch-screen display that not only shows crystal-clear images but also allows for intuitive control of system parameters. Unlike conventional receivers, the WV-7012HD is enhanced with a spectrum sweep function that provides users with real-time frequency scanning capabilities. This helps operators quickly identify interference from nearby devices, enabling fast frequency allocation and improving overall link stability.

Avec le soutien de COFDM and DVB-T2 modulation, the receiver is capable of handling both line-of-sight (LA) and complex NLOS environments, ensuring robust and uninterrupted video reception in urban areas, tunnels, or moving platforms. The device is also optimized for transmission mobile à grande vitesse, making it suitable for applications where reliable reception is required under rapid movement, such as UAV ground stations, vehicular platforms, or field operations. Its small size and built-in rechargeable battery (Jusqu'à 3 hours of continuous use) make it a practical choice for professionals who need a portable yet powerful video monitoring solution.
