The system allows one to view live-streaming video over home/business personal computers, over the Internet at remote locations and from mobile phones. So, for example, if you are on vacation and want to see what's going on in/around your home or business, you can login over the Internet by logging into to Logitech's web portal and see realtime streaming video from your cameras.
Below are screenshots of the quality of video, the web, Internet and mobile phone video viewing interfaces.
Incidentally, the cameras have high-definition night vision, tilting, panning, zooming and audio listening & recording capabilities built in, that is without spending additional money.
The screenshot above is a screenshot of the desktop software used to view image from the cameras - i.e, from your home/work personal computers or workstations using the software that came with the camera/s made by Logitech.
The screenshot above is of the cell-phone interface - i.e., viewing over your cellphone. You just need to have a "smart phone", and download an application from your "app" store. Logitech mobile applications exist for Android, iPhone and BlackBerry cellphones.
