A rear camera is a type of camera that is mounted on the back of an electronic device, such as a smartphone or tablet. The primary purpose of this camera is to capture photos and videos from behind the device. This can be useful for taking selfies, recording video footage while facing away from the camera, or capturing images in situations where it may not be possible to use the front-facing camera. Rear cameras typically have higher resolutions than front-facing cameras, allowing for better quality photos and videos.
