 MV2025 4-CH portable receiver

Introduction

The 4-CH Portable Receiver is specially designed for multi-channel receiving application. It can receive audio and video from four transmitters (MV2025 series transmitter) at the same time. The whole system adopts the latest technologies of COFDM modulation and MPEG-2 image compression that enable good NLOS (Non line-of -sight) transmission with DVD video quality. And the built-in 4-picture DVR (Maximal capacity is 500GB) can record the real-time audio and video. Users can play back the recorded image any time on the computer and choose the portable mini transmitter (MV2025TTLE) to finish covert mission. The encryption of AES128 bit/ ALLTECH Basic Scrambling ensure the transmission security. The whole system is highly integrated and can realize wireless video transmission in mobile and NLOS (Non line-of-sight) conditions.
