Most people have a webcam these days, but those who don't or do not wish to share the real images can easily emulate this accessory by using an application like Fake Webcam.
This easy to use software can use any video and act as a traditional webcam on most applications that need such a piece of hardware. Just as well, it enables you to choose an area of the desktop and have it displayed instead of the real image.
Because the interface is pretty simple, you just have to pick one or more movie files you want to stream, click it and hit the play button and that's basically it. A nice feature you will find in the settings menu allows you to put a certain video in loop or let all the items on the list play sequentially.
There is also a preview function for videos that gives you the possibility to check out the movies prior to allowing them to be streamed from your PC via an instant messaging application or Flash websites. Fake Webcam supports a variety of chat programs that include Yahoo! Messenger, Windows Live Messenger, Skype, Google Talk or ICQ, just to name a few.
During out tests we found out that this software is quite friendly with computer resources and this means you can run it on older machines without too much hassle.
No matter the reason for using it, Fake Webcam is certainly among the best tools of its kind, so in case you really need such an aplication, be sure to give this one a try.
