Labview 7.0 - Web Cam

Labview 8.5 WITH VISION A project that I wanted to do is writing a Labview application that would communicate to the USB Webcam and publishing the application on a secured web page and allowing the users to control Labview applications at home, work and anywhere in the world without having Labview software installed on PC. On the web, the users can control Labview front panel to zoom, do annotations, etc. Like a surveillance camera the USB Webcam will be detecting an object moving, save images from when motion was detected, trigger an alarm to alert. I also don't know what web cam i should purchase, so please help by telling me what web cam will work so i can purchase it.
