I google'd quite a while about this topic, without any satisfying result. Actually my basic question is: Is there any possible way to access a webcam with Javascript ?
Maybe with HTML5 ? <video> element ?
What are options as developer to access the computers webcam anyway?

Please see this answer:
It is possible with beta browsers but if you want to developer something for IE users you need to stick with Flash.
