Some scammers from Ghana, Nigeria, Russia or other countries will stream a fake webcam stream when you chat with them on webcam. They do this by using a pre-recorded video that appears as if they are the person on the other end of the webcam. In order to protect yourself from fake web cams ask the person to verify that they are not a recording by standing up, waving, holding up a hand or writing a message on a piece of paper and holding it for you to see. If the person is real they should be able to obey your requests in real time. If the webcam is fake they will be unable to do any of these things in real time.
