Note
:
Use Infra-Red Pass filter to cover the lens during focusing to
simulate low light conditions on scene for correct 24-hour focusing.
For camera with manual iris lens, the camera should be focused with
the lens iris fully opened to simulate the worst possible depth of field.
Using a Infra-Red Pass filter will ensure the iris is fully open for cor-
rect setup and adjustment.
Note that statement above is applicable only for Day/Night or IR
version cameras.
