Hey, sorry the delay but I just found this.
I have a regular BenQ camera that can be used as a webcam.
Looking for a software for motion detection I founded this one:
And I would to say it is just great !
The motion detection is fine.
It can create a avi file and/or several jpg snapshots just when motion is detected. There are several options to control almost everything you want.
And the real time images can be accessed by a internet browser in a specified port. It's just what you asked for.
I am very happy with.
