pick out and buy the camera that matches your needs. We've been using one of these cameras for a number of years and they work great. We can set up the camera to automatically send image files to a server on a preset schedule and rate. With some home grown scripts, we convert the images to movie files for viewing. We first tried a D-LINK camera before the AXIS, but it just doesn't work well at all and often goes out to lunch for no apparent reason. Hope this helps some.
