Overview

The WV-7012HD 7-inch Portable COFDM Receiver is a newly designed, lightweight, 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.

With support for COFDM and DVB-T2 modulation, the receiver is capable of handling both line-of-sight (LOS) and complex NLOS environments, ensuring robust and uninterrupted video reception in urban areas, tunnels, or moving platforms. The device is also optimized for high-speed mobile transmission, 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 (up to 3 hours of continuous use) make it a practical choice for professionals who need a portable yet powerful video monitoring solution.
