1. DESCRIPTION
The EX27 camera is an all-weather system that
includes all of the best features of a “plug and
play” camera without compromise to CCD optics
and lens quality.
Full size vari-focal auto-iris lenses are integrated
as standard equipment for simplified
installations. High resolution extended day/night
CCDs ensure that a picture is received under
extreme outdoor lighting conditions.
The EX27 is rugged, compact, power protected,
weather sealed, easily installed and designed for
use in industrial applications.
A voltage regulator circuit automatically allows
for 12VDC or 24VAC operation without any
wiring changes. Its wider voltage range also
provides protection from voltage surge, transient
spikes, and reverse voltage.
The EX27 is available in several models to meet
individual requirements or specific needs.
