First, use the borescope to view the front horizontal line.

In this state, placing a cylindrical object like the one in the photo below does not allow the wall surface to be visible.

 

 

 

 

Place a cone mirror and then position the cylindrical object as described above.

 

 

 

 

It enables 360-degree (omnidirectional) capture as depicted in the lower photograph. However, the central area is significantly scaled down, limiting effective use to the outer periphery.。
