To use a camera on a computer, you typically need to install camera software or drivers that are compatible with the specific make and model of the camera. This software is designed to allow the computer to recognize and communicate with the camera, enabling you to capture, view, and edit images or videos. Some cameras may also require additional software for advanced features such as editing, organizing, or sharing files. It is important to check the manufacturer's website or user manual for the specific software requirements for your camera model.
