pression.
Besides a comprehensive set of automatic and manual image optimization
functions and many other setting options, it features automatic Day/Night op-
eration supported by integrated ambient light sensing, a removable IR cut filter
(ICR) and an integrated homogeneous IR illumination provided by semi-covert
850 nm high power LEDs in order to meet even the most demanding of surveil-
lance conditions.
In addition, the camera is equipped with a fast (large maximum aperture) and
motor-driven P-Iris megapixel varifocal lens which allows for the convenient
adjustment/configuration of the focal length (zoom), focus and iris (aperture)
via the web browser.
The novel P-Iris control technology, designed for a precise and automatic ad-

cantly improved image quality (compared to conventional DC auto iris lenses)
with excellent contrast, brilliant clarity and enhanced detail resolution combined
with a greater depth of field under almost all lighting conditions.
In conjunction with the Digital Image Shift function, which provides for a subse-
quent digital fine alignment of the image section, a convenient and straightfor

ward installation process of the camera is guaranteed.
Built into an IP66-rated weather-proof enclosure, the camera is designed for
both indoor and for outdoor applications.
The camera is operated via Power over Ethernet which allows for an easy,
quick and cost-effective cabling and commissioning.
