Supply Dual SIM 3G wireless man

Features: (1) special DSP solution, embedded structure design, small size, high integration, high reliability, high anti-seismic performance drop. Low power consumption, single card 3G video server average power less than 3w. Dual SIM 3G video server average less than 5W. (2) efficient H.264/AVC video coding, easy low-bandwidth HD video transmission equipment to achieve dual-stream, respectively, for wireless transmission D1 front-end and high-quality video. (3) Dual Sim 3G network bandwidth adaptive technology, according to the network bandwidth automatically adjust video frame rate, CIF images up to 25 frames / sec, D1 images up to 20 or more. (4) Transmission delay is small, with an average delay of less than 3 seconds; bandwidth is poor, the delay can be adjusted manually ensure that the video does not drop frames. (5) support for simultaneous transmission of audio and video, front-end high-definition audio and video storage. Two-way intercom function. (6) Built-in hardware dogs, Abnormal automatic recovery, automatic connection after network outages, ensure that the system is stable and reliable. (7) platform software is powerful, highly integrated, easy expansion. Supports hierarchical user rights management, can be divided nowhere viewing rights of users, control user access to watch the amount of video resources. (8) using the data stream encryption technology to ensure network communications security, secure communications SSl a professional service, you can define your own encryption method. (9) Timing and SMS sleep, heartbeat data link multi-mode coexist, can effectively save the user data traffic costs. (10) SD card storage, there is no maximum limit space, seismic effect.
