Tips About CCTV Lens Features

CCTV lenses have a lot of
different features and it is a
good idea to know some of
the different ones available and
how they affect your
surveillance system or your security cameras. So before
purchasing a cctv lens for your
camera, take the time to read
through this and gain some
insight to some of the more
popular features and what they do.

There are few different types
of CCTV lenses out there
including C/CS, M12, & M9; we
will be going over features and
styles indicative of the C/CS
mount style however, as they are the most common and
applicable.

The main difference between
these types of lenses that you
should know about is that M9
and M12 are board type lenses
used with board, miniature,
and bullet style security cameras; whereas C/CS mount
lenses are used on C/CS mount
cameras.

Additionally M9 and M12 lenses
are usually set focal length
lenses, and they will have to be
replaced with a new lens to
have a different focal length.
We will talk more about varifocal vs. fixed focal length
later on.
