Shooting Image
A single camera captures a wide range of images
One of the advantages of ultra-wide-angle fisheye lenses is that a single camera can capture a wide area.
For example, if you want to record images of an intersection, you would need to use multiple cameras with a standard lens, but with a 250-degree lens, you can record all four directions of the intersection with a single camera. Reducing the number of cameras provides advantages in terms of cost reduction and maintenance.
