A webcam enables you to keep in touch with your friends and family through video chat. Many Sony camcorders are equipped with a USB Streaming port that enables you to use them just like you would normally use a webcam. However, you must use the AC power adapter to power your camcorder and have the USB Streaming driver installed on your computer before you can attempt to use the device as a webcam. You can find the USB Streaming driver on the disc that came with the camcorder. Warnings Writer Bio
