Last time i sat on a laptop without webcam an wanted to make a videocall. I searched for a solution to connect my andorid camera to my pc and found two solutions: IP Webcam DroidCam Wireless Webcam Both need some additional software at the pc to present some common webcaminterface to your voip or im software and both are advertisefundet. Dont know if there is a advertisefree verion of IP Webcam but there is a "pro" version of DroidCam Wireless Webcam which is free of the timelimit. I decidet to test DroidCam longer because the software which is needed on the PC worked out of box (at least with skype), while the software of IP Webcam (option 2) crashed.
