The
CSL-550A can be used to provide a dynamic field of view control
between 5.3mm and 46.9mm focal lengths. And because its focal length
is always higher than 5.0mm, there is no curvature distortion in
the video image as seen with very wide angle lenses.
This is a varifocal
zoom lens, and all lens adjustments must be made manually by hand.
Once the desired focal length is acheived, the lens has thumb screws
which tighten to maintain that specific focal length. We also carry
fixed focus C-mount lenses for those applications where desired.
The CSL-550A
employs voltage from the camera's auto-iris port to automatically
adjust the amount of light which passes through the lens optical
glass and reaches the imager. This feature allows for brilliant
lighting in many diverse and changing lighting conditions. However,
its extra light gain sensitivity can make the video image too bright
under certain direct forward lighting circumstances. When room illumination
is likely to remain constant, a manual iris lens in fact offers
better overall image quality in many situations. For these types
of camera installations, we also carry the CSL-550M.
This lens has
a security-industry standard CS-mount lens thread, making it compatible
with the following Eyespyvideo.com models: TV-CSHRL,
TV-CSHR,
TV-CSHDN,
and TV-BCSHR.
The auto-iris port on these cameras provides seamlessly compatibilty
with the CSL-312A. However, this lens is NOT compatible with the
special auto-iris port built into the TV-HDCS
model camera. We offer a variation of the CSL-312A for this camera,
our CSL-550X.
