Because standard and high-definition television's do not typically have USB cable inputs, additional hardware is required to hook up a USB webcam to your TV. There are two options: using a USB-converter cable, or connecting a computer to your television to facilitate the connection. The method you choose depends on your goals for connecting the webcam to your television. For example, if you want to initiate a video chat using your television as a monitor, a computer is required.
Using a USB Converter Cable
Connect the circular end of the USB converter cable to the S-Video port on your television.
Plug the USB dongle on the webcam into the square end of the USB converter cable.
Place the webcam near the TV using the clip included with the device. Arrange it so it points in the direction of the image you want to capture.
Press the television power button and then use the remote to cycle through the input feeds until you see the image provided by the webcam.
Using a Computer Connection
Place your computer near the television to allow adequate space for your cables to connect from one device to the other.
Connect one end of the VGA cable to the video port on your computer and the other end of the cable to an available port on the rear of the television.
Plug the 3.5-mm side of the audio cable into the headphone or audio-out jack on the computer.
Connect the red and white plugs on the audio cable into audio-in ports on the rear of the television. Be sure to match the colors appropriately.
Insert the USB plug from the webcam into an available port on your computer.
Power on all devices. Press the "Input" button on the TV remote to find the VGA signal from the computer. You have the right input channel when you recognize your computer desktop background on your television screen.
Initiate the webcam software or a program that uses the software, such as an instant messaging application. Arrange the webcam so that it captures the image you desire.
