1 About the Cheetah Camera
1.1 General
The Cheetah series of cameras are built around a robust imaging platform utilizing the
latest digital technology and components. The Cheetah C4080 and C2280 KAC camera
series is designed around two different CMOS imaging sensors featuring different
resolutions and frame rates. The cameras are available in monochrome and color.
This user manual provides information C4080 and C2880 cameras designed for Camera

Table 1: Cheetah C4080 and C2880 cameras overview.
The Cheetah cameras are advanced, intelligent, high-resolution, progressive scan, fully
programmable and field upgradeable CMOS cameras. They are built around the ON
Semiconductor area scan CMOS imagers and are feature rich with a built-in image
processing engine, low noise, and efficient and optimized internal thermal distribution.
The Cheetah cameras feature a wide range of programmable functions; including, dual
video options, extended dynamic range, exposure control, frame rate control, area of
interest, subsampling, pixel averaging, gain, offset, several triggering options, strobe
output control, transfer function correction, temperature monitoring and user
programmable and up-loadable LUT.
The user can program either a rolling shutter for the widest dynamic range or global
shutter for superior motion capture. The dual video mode allows two independent
acquisition frames (Frame A and Frame B) to be programmed with independent control of
exposure time, area of interest (AOI), subsampling, gain, offset and wide dynamic range
parameters. Additional controls support a variety of ways to seamless switch between
frames.
Exposure time for each frame can be controlled using an internal control or controlled by
an external pulse width. Exposure times up to 1 second with 1µs increments in rolling
shutter mode and 5µs increments in global shutter mode are supported. A custom AOI
can be programmed for each acquisition frame and subsampling or pixel averaging
capabilities are also available. Pixel averaging is a unique feature providing reduced noise
and improved signal to noise ratio by blending adjacent pixel information together.
Analog gains up to 12 dB (4x) in 12-bit digitization mode and 18 dB (8x) in 10-bit mode are
available. Digital gain controls allow further expansion of the low-end signal with 24dB
