Hi Thomas,
unfortunately you will need some kind of application that steers the webcam. With Logitech that was probably the Logitech proprietary software like Logitech Capture. The EMeet webcam doesn't come with that kind of proprietary software, hence the price difference with Logitech, but you could use Youcam for example to test your webcam (search for Youcam in your browser or go to https://www.cyberlink.com/products/youcam/features\_en\_EU.html?r=1). Otherwise in Skype you can go to Audio & Video settings before opening a live session to test your webcam. You can find these settings by clicking on the three dots on the right of your name in Skype, go to settings and then click on Audio & Video.
Regards, Menno.
