CCTV | Varifocal Lenses

For optimizing angular fields right on site, varifocal lenses

are the most versatile and practical solution available.

These lenses allow for setting virtually any angle of field,

which maximizes surveillance effects. Installers do not need

to carry several different focal length lenses – and

installation is more efficient because they can find the right

angles of field without moving the camera set-up. If the

field-of-view requirements change after installation,

modification is simple by just altering the lens’ focal length

settings.

Functions

This series includes both manual and DC-iris varifocal

lenses. They are compact, rugged, and available in 1/3-inch

and 1/2- inch image formats. The series is organized by

sensitivity, optical resolution, and range to match the wide

range of Dinion camera applications.

These varifocal lenses come with a standard C or CS mount

for use with a variety of cameras. The DC-iris control

connection is a four-pin standard plug that fits directly into

the camera’s iris output. And the lenses deliver impressive

optical quality due to their high standards for resolution,

contrast reproduction, and coating.

The mechanical construction is designed to withstand both

frequent DC-iris control operations and the environmental

stress of security installations. For flexible, high-quality,

reliable lenses that match a camera’s performance, this

varifocal series is the ideal solution.
