Motion (http://www.lavrsen.dk/foswiki/bin/view/Motion/) is a small, lightweight but powerful application software that can be used to manipulate security cameras on Linux. It works in concert with any Linux-enabled camera, including all v4l webcams, many IP cameras, and NCR (Axis) cameras, which also control panning and tilt functions. Motion can record videos and snapshots in formats such as JPEG, PPM, and MPEG, which you can view remotely in a Web browser, thanks to Motion's built-in HTTP serv

The above post is about the camera (WebCam) in Linux using Spcaserv set up network Video Monitoring Server (V0.1B).
Here I will simply talk about Linux install Linux camera driver.
In the new Linux kernel there is a majority of USB camera drivers. So you can choose to drive directly from inside the kernel.
First you have to determine your camera model:
$ Lshal | grep
Hardware: Development Board, OV511 camera, notebook or desktop

The first step: test whether the camera can run normally (Linux support ov511, so the driver source code can be directly compiled by the kernel).
If the kernel is compiled, the kernel will be recompiled and the appropriate configuration options should be selected. My is ov511 so do
