C20-CH SERIES
The C20-CH Series is Pelco’s general purpose digital color CCD
camera. It is designed for installations with fixed lighting conditions.
Its full features insure that images are clear and crisp at all times
under consistent light. The camera’s size, combined with its
numerous features, makes it the ideal camera for most applications.
The C20-CH Series is an ultra high resolution digital camera with
650 TVL of resolution and 0.25 lux minimum illumination. Camera
features include autosensing power (24 VAC or 12 VDC with internal
synchronization), and automatic gain control (AGC).
The C20-CH Series includes automatic white balance (AWB) for
difficult lighting situations, digital noise reduction for clearer image
quality, and backlight compensation (BLC) that adjusts the picture to
prevent objects from appearing dark due to a strong backlight.
The C20-CH Series also features built-in analytical capabilities
including privacy zones, motion detection, and camera titles. These
features are easily set using the on-screen menus.
The convenient on-screen menu contains features that are not
typically found in a general purpose camera including area masking,
titling, pixel correction, and preset lighting profiles.
The C20-CH Series is quick and easy to install. The camera is also
featured in Pelco’s DomePak
enclosure packages. The optional C10-UM wall/ceiling/rail mount kit
offers easy installation in many nonenclosure applications, for all
models.
The C20-CH Series has a standard CS lens mount and can be used
with fixed, manual, or auto iris (DC drive) lenses. The iris is controlled
through a standard 4-pin square connector that is included on all
Pelco auto iris lenses.
