Q1: What is the Warrranty for the lens?

A1: For the lens, we have 1 year warranty. If any quanlity problem on our side in this period, we will take on the shipping cost and replacement.

This position is called the depth value where getting the best use of lens, optical error greatly reduced. The best image quality can be obtained.(In contrast, resolution and depth of the field area) This is the default setting of the IP Camera with P-iris.
