All iPhone models have a digital camera built into the hardware, allowing you to take photos and record videos. The iPhone’s digital camera can be utilized as a PC webcam by downloading a third-party application, such as WebCamera or iWebcamera from the iTunes App Store, and installing its client software on the computer. The PC can then connect wirelessly to the iPhone and capture images recorded by its digital camera in real-time. These images can then be routed to communications software for use as a webcam broadcast. Writer Bio
