Monitor Employees via WebCam

[victorgrant]

Hi,

I'm contemplating installing software to monitor employee activity...mainly 3rd shift. I've viewed some applications, but was curious if anyone here has a preference or experience in this area. Here are my main needs:
Must be discreet. I want to ensure there's no Add/Remove Program listed. No icon appearing in the system tray when activated.
I don't want a resource hog affecting the PC or bandwidth.
Can monitor or access data remotely, as well as store specified data indefinitely.
Must not turn on the built in cam LED light. This is where I'm not finding any answers. If the built in LED comes on, as it normally does when the cam is in use, it would defeat the whole purpose of monitoring.Decent app support.
I'm looking at 9 machines right now. I obviously don't want to pay an arm and a leg. Any info, or useful feedback is much appreciated.

Please help.

I didn't find the right solution from the Internet.
