RE: Web Cameras and CF
Try: http://www.webcam32.com/ you can have a live feed using a java applet that you mandate forced live feed or update intervals, as well as having timed shots taken and FTP'd to the server for storage. No CF needed.

Re: Web Cameras and CF
I had to set up a system like this for a client. Basically, the process needs to work by attaching the web cam to a video board (like the Winnov) and having software that snags a jpg from the video feed every 20 minutes. Generally speaking, as long as the video board supports Video for Windows (known as vfw), then the web cam software you install should be able to work with the board. There are some setups that allow you to remotely control the camera (pan and zoom) and you may need tighter integration between web cam software and video feed in that case. I tried using Webcam32 and found that I really didn't like it much, in spite of the fact that it appears to be the most popular software out there. Right now, we're using ChillCam (http://www.thegeek.com/chillcam/default.asp) and I'm pretty happy with it thus far. We have the software running on startup on two P133's with 32MB of RAM running NT SP5. It's running NT because the client has the machines sitting in broom closets and such and doesn't want people to have easy access to the machines. We have it set to grab a photo every 2 minutes and ftp the image to the web server. On the web server, I've got a scheduled task set up to copy the file into the main web directory every two minutes. I do this so that there won't be any file locking problems with the web server accessing the file while the ftp session is trying to upload it. The scheduled task checks to make sure that the file exists, that it's not a 0 K file, that it's newer than the file being overwritten, etc. and then copies the image. I've got it set to run 6 am to 4:15 pm (ski resort hours). By and large, it's worked fine. We ran into a problem when we added a second camera. To make a long story short, we were running into problems when 2 ftp sessions were writing files to the same directory at the same time. We ended up assigning each camera a different ftp username and a different home directory so that we don't have any file/directory locking issues. Besides that, it's been pretty straight forward.
