I've been looking for Windows webcam software that will run as a Windows service without any user login. The goal is to use the webcam as a cheap security camera and log the results to secure networked storage (windows share, not FTP). The requirements are:

1. Motion detection
2. Video capture
3. Runs as a service (should start recording immediately after reboot)
4. Nice to have: Round-robin storage, e.g. 10Gb limit, oldest files overwritten/deleted when space gets low

I've read the other webcam questions but still haven't stumbled across anything suitable.

Evaluations thus far:

Camera: Logitech Webcam Pro 9000
Windows 7 32-bit
WebCamsPy failed to initialize so couldn't be tested

So far, the contenders:

• Active Webcam comes the closest, and claims to run as a service, but i haven't been able to get it to record after a cold boot even though a service is running.
• Yawcam can be set up as a service but doesn't record video.
• IspyConnect has exactly the type of space limit I want and looks great, but doesn't run as a service (seems also to be a bit of a cpu hog)

Any other suggestions? I'm locked into Windows so can't use linux Motion, which looks almost perfect. Any pointers to rich Windows webcam/motion detection libraries out there that could easily be turned into a command line program would also be appreciated.
