3.Software System
（1）Linbian OS
The recommended OS for normal use on Lindenis V5.
A free operating system based on Debian, optimised for the Lindenis V5 hardware. You can use it to build some creativity app, or use it for engineering validation test. Feel free to coding and compiling on it directly, no need to cross build anymore.
Scalable. The image is easy cut to 16MB and store on SPINOR
（2）Applications
Media player：A GStreamer based video player.
Camera：A GStreamer based camera app.
Streaming Server：A GStreamer based RTSP server.
Face recognition：A face detection and recognition app.
Motion detection：A intelligent motion detection app.
Human counting：A human counting app
VLPR：A vehicle license plate recognition app
