An instrument commonly used to look over walls is a periscope. Periscopes are designed to allow users to see objects that are not directly in their line of sight, typically by using a system of mirrors or lenses to reflect the view. They are often used in submarines and by military personnel. Another example is a telescoping pole with a camera or mirror attached, which can also provide a view over obstacles.
