InstaView is a feature commonly found in smart refrigerators that allows users to see the contents of their fridge without opening the door. It typically uses an internal camera to capture images of the items inside and displays them on a touchscreen panel on the outside. This helps users quickly check for ingredients or leftovers, reducing energy consumption and food waste. The technology behind InstaView often includes a user-friendly interface that can be accessed via a smartphone app. Some models also integrate with other smart home devices, allowing for seamless management of grocery lists and meal planning.
