Can the iPad Do Webcam Functions?
Apple's camera-equipped iPad models can be used for webcam functionality. The original iPad did not have a built-in camera, but all models from the iPad 2 on are equipped with at least one camera. The iPad can use its built-in camera as a webcam for apps running on the device. A traditional computer can borrow the iPad's camera stream like a webcam with the assistance of an app as well.
1 Apps on the iPad
The iPad can use its built-in camera like a computer uses a connected webcam within apps. Aside from being able to take pictures and record video, the iPad supports webcam video calling through the included FaceTime app. FaceTime can work over Wi-Fi for non-cellular-equipped iPads. Third-party apps like Skype can also use the built-in camera for video conferencing.
2 Borrowing the Webcam
If you're looking to use a webcam with your computer, you can use the iPad's camera for the job with the assistance of a third-party app. Apps like iCam, Instant Webcam and EpocCam create and broadcast a video stream from the iPad's camera on the local Wi-Fi network, which the computer can pick up and use like a video feed from an attached webcam. The webcam apps require installing a program on the computer to bridge the video stream.
