1 About the Cheetah Camera
1.1 General
The Cheetah Python series of cameras provide a robust imaging platform with the latest digital
technology and industrial grade components. They use CMOS imaging sensors and offer a
broad range of resolutions and frame rates. Cheetah cameras are available in both
monochrome and color.
The cameras in this manual are compatible with the GigE Vision® (GEV) and 10 GigE Vision
(10G) output interfaces, support GigE Vision Standard v1.2 and use a GenICam™ compliant
graphical user interface for programming.
The following table provides information about the C5180, C4181, and C4180 cameras.

Cheetah CMOS line of cameras are ruggedized, for greater durability and performance. They
offer high-resolution, progressive scan technology and are fully programmable and field
upgradeable. Programmable functions include automatic and manual exposure control, frame
rate control, area of interest, subsampling, pixel averaging, automatic and manual gain
control, offset, triggering options, strobes, output control, defective pixel correction, and
user-programmable look-up tables (LUT). The cameras provide support for active Canon EOS
lens with Iris and focus controls. The cameras use ON Semiconductor area scan Python CMOS
image sensors and feature a built-in image processing engine, low noise characteristics, and
optimized thermal distribution.
The cameras use global shutter operation for superior motion capture with exceptionally high
frame rates for high throughput applications. You can synchronize the cameras to an external
trigger source and vary exposure times using internal controls or an external pulse width. The
cameras support exposure times up to 1 second with 1 µs increments. An Area of Interest (AOI)
can be programmed for each acquisition frame, and subsampling or pixel averaging capabilities
are also available. They also support analog gains up to 10 dB (3.17x) and allow further
expansion of the low-end signal with 24 dB (16x) of additional digital gain available.
Built-in gamma correction and user-defined look-up table (LUT) capabilities optimize the
camera’s dynamic range features. Defective pixel correction (DPC) and hot pixel correction
(HPC) correct for pixels that are over-responding or under-responding. Auto White Balance
(AWB) is available in color cameras to correct for color temperature. The cameras have a
compatible interface that includes 8- and 10-bit data transmission, as well as camera control
functionality in one cable.
The camera’s ruggedized design and flexibility enable its use in a diverse range of applications
including machine vision, metrology high-definition imaging and surveillance, medical and
scientific imaging, intelligent transportation systems, aerial imaging, character recognition,
document processing and many more.
1.1.1 GigE Vision Interface
The GigE Vision and 10 GigE Vision interfaces operate on standards designed to enable high-
speed video transmission and control over Ethernet networks. The standard enables
compatibility with Ethernet CAT 5 and 6 cables and components installed on many PCs. In
many cases, GigE and 10 GigE Vision provides a drop-in solution for existing networked
cameras with its GenICam compliant user interface (GUI) for programming the camera.

1.4 Technical Support
Imperx fully tests each camera before shipping. If the camera is not operational after power
up, check the following:
1. Check the power supply and all I/O cables. Make sure all connectors are firmly
attached.
2. Check the status LED and verify it is steady ON. If it is not, refer to the section
2.6 LED Status Indicators.
3. Enable the test mode and verify that the communication between the computer and
the camera is established. If the test pattern is not present, power off the camera
and check cabling, IpxPlayer settings, and computer status.
4. If you still have problems with camera operation, contact technical support at:

2 Hardware
2.1 GEV Camera Back Panel
The back panel of the camera provides connectors needed to operate and control the camera.
The panel also provides a status LED indicator. The panel includes:
1. A standard RJ-45 connector provides data, sync, control, and serial interface.
2. Two mounting holes to use with an Ethernet cable with horizontal locking screws for
a secure connection.
3. A male Hirose type miniature locking receptacle #HR10A-10R-12PB (71) provides
power and I/O interface.
4. A USB type B programming/SPI connector for factory use only.
5. A camera status LED indicator.
6. The camera’s model / serial number.
Figure 1: GEV-C5180, GEV-C4181, and GEV-C4180 camera back panel
The camera transmits serialized video data output and communications over the Gigabit
Ethernet interface with consistently low, predictable latencies. The network interface is
compatible with IP/Ethernet networks operating at 1000 megabits per second using LAN
CAT-5 (CAT-5e) or CAT-6 cables. Shielded cables are recommended. The cable length can
reach up to 100 m. For longer distances or harsh environments with high electromagnetic
interference (EMI), CAT7 (or higher) cable is required.
