Mobile Network Video RecorderThis system performs mobile surveillance using end-to-end digital video, audio, and sensor-recording technology. Firmware on this recorder can captures live video and audio from IP cameras connected to board via Ethernet capture cards. The captured live video and audio is recorded and played back on standard media player like VLC. The board contains many other peripherals/interfaces like accelerometer, GPS, cell modem, RTC, sensor input and output.
