Pelco Manual C1925M (3/99) 7
LENS INSTALLATION
GENERAL LENS INFORMATION
CCC4000 Series cameras are factory adjusted to the CS-mount standard. Fixed iris,
manual iris, or passive (DC controlled) auto-iris lenses may be used. Passive (DC
controlled) auto-iris lenses require a standard 4-pin square connector (type D4-152N, not
supplied) that is standard on all Pelco lenses.
C-mount lenses are also compatible by using a Pelco PCMA40 C/CS-mount adapter. Refer
to Figure 4.
Important Lens Notes:
Passive (DC controlled) auto-iris lenses are recommended in outdoor applications to
control lighting changes and prevent picture smear.
This camera will not support active (video controlled) auto-iris lenses (having a built-in
electronic circuit for driving the iris).
