Automotive drive / SD card video recorder car video surveillance system is the core equipment, storage and transmission of complete car video encoding, the video recorder built-in wireless 3G transmission module, specially designed for vehicle system application environments such as earthquake temperature . The main functions are as follows: 1. Supports multi-channel audio and video recording, playback and transmission. 2 local screen displays, graphical menu interface, support mouse and keys. 3 using the H.264 video compression standard, support D1 resolution compression, support dual-stream real-time video encoding and network transmission. 4 built-in GPS module, GPS information to save and reporting. 5. Built-in 3G module supports China Unicom, China Telecom 3G network. 6 according to the limited bandwidth of the wireless network connection unstable situation, automatically adjust the network coding and transmission strategy, adapt to different network conditions. 7 to support two-way voice intercom. 8 key components of automotive electronics devices, military grade components and high reliability imports of new materials to improve product stability, allowing the device to the vehicle vibration, high temperature, cold, dusty, humid environment. 9. Military technology and high reliability of imported materials, provide superior cushioning and anti-seismic protection of the hard disk, combined with the of electronic earthquake and seismic software technology, effective solution to the problem of vehicle shock and vibration. 10 Wide voltage design, no external power supply, power can be applied all kinds of vehicles. 11. Supports multiple level or I / O mode, the input and output interface, and can simultaneously access a variety of different baud rate control and alarm equipment. 12 reserved interface with the vehicle traveling data recorder connected.
