To get a wider view, it should be convex lens, but if a person can look outside through that hole than the outside person also can see the inside person, but we all know it's not happen, and if happened then why we put that hole.
Actually that is special arrangement of convex lens which is also called fisheye lens.

In a door, a peephole allows people inside the security of seeing outside without opening the door. Glass peepholes are often fitted with a fisheye lens to allow a wider field of view from the inside and little to no visibility from the outside.[1]
its from Wikipedia not from me sir
The door lens is concave lens.
