Current generation CPUs with energy saving technologies can cause bandwidth problems on the USB
bus. See section on PCs With Energy Saving CPU Technology.
Large multi-camera systems
Connecting a large number of cameras to a single PC may require a large working memory (RAM). This
is especially the case when many cameras with high sensor resolution are used.
If you want to set up such a system we recommend to use PCs with 64 bit operating systems and more
than 4 GB of RAM.
Note on color cameras with high frame rates
For uc480 color cameras, the color conversion is done by software in the PC. When you use a color
camera with a high frame rate, the conversion might lead to a high CPU load. Depending on the PC
hardware used you might not be able to reach the camera's maximum frame rate.
Direct3D graphics functions
The uc480 driver can use Direct3D to display the camera image with overlay information (Microsoft
DirectX Runtime had to be installed). On Windows systems, you can use the supplied "DXDiag"
diagnostic tool to check whether your graphics card supports Direct3D functions. To start the diagnostic
tool, click "Run…" on the Windows start menu (shortcut: Windows+R) and enter "DXDiag" in the input
box.
On the "Display" page of the diagnostic tool, click the button for testing the Direct3D functions.
OpenGL graphics functions
For OpenGL version 1.4 or higher must be installed. The OpenGL graphics functions do not work with QT
under Linux.
1.4 DCx Camera Family
DCx cameras stand for a range of compact and cost-effective cameras for professional use in
industrial, security and non-industrial applications. Equipped with the widely used USB 2.0 and
particularly USB 3.0 ports, they can easily be interfaced with a vast variety of systems. The images
are digitized in the camera and transmitted digitally to the PC. An additional frame grabber is not
required.
DCU cameras have state-of-the-art CCD sensors while the DCC models are CMOS based. The
CMOS models use either the global or the rolling shutter method; the CCD models use only the
global shutter method.
The DCx cameras are available as monochrome and color versions, DC3240 series has a NIR
version as well. The Model Comparison chapter shows the most important features of every series
at a glance.
