Lens PLEN-0202 Performance with KCM-5111
Introduction
KCM-5111 is an attractive indoor box camera
because of its excellent 4-Megapixel video quality.
Although KCM-5111 comes with the bundled fix
lens (2.8mm/F2.0, 82.59 ° ) and although it
supports a powerful P-Iris vari-focal lens, we have
still received so many requests for one more lens
option – a vari-focal lens with manual iris with
the range of focal length that would perfectly fit for
indoor applications.
Manual iris would be attractive for two reasons:
1. since the indoor lighting conditions are usually very stable and sufficient, there iris does
not need to be controlled automatically, which leaves the option of having either cost
efficient manual or fixed iris
2. by having the manual iris it is possible to take a good use of proper lighting conditions
and reduce the size of the iris as much as possible in order to gain the longest possible
depth of field (the area in the field of view where every object is in clear focus). As the
ideal concept of security surveillance requires everything in the field of view to be in
focus, therefore it is much easier to reach the ideal depth of field by using a manual iris
lens.
