Is there any (free) way that I can connect a mobile phone with video camera as a web cam in the computer with Windows Operating System? For instance a traditional Nokia phone (not a very new smartphone).
Try Mobiola's WebCamera software.
Turn your iPhone, BlackBerry, Windows Mobile or Symbian (Nokia only) smartphone into a high-quality wireless webcam. Connect it to a Mac (iPhone version only) or PC using a Wi-Fi connection, and share bright moments of your life that cannot be caught with a built-in webcam or USB camera!
