The Hardware Up to 16 digital cameras with integrated image chips from Sony’s Pregius series deliver high-resolution images with 1.6 or 5 MP in color or monochrome – even in dynamic applications. Thanks to the compact housing (29 x 29.1 x 29 mm), they’re ideal for installation in systems with limited space. Any desired C-mount lenses can be attached to the digital cameras, in order to implement applications in both close-up and distant ranges. Three different types of illumination can be selected for homogenous, constant lighting within the application. Ring lights, spotlights and backlights are available in different sizes and colors: red and infrared light in flash or continuous mode are offered in addition to white light. And last but not least, all of the image data generated by the system come together in the control unit: all processing is conducted and results are evaluated in the fanless housing (passive cooling). Equipped as desired with either an i3 or an i7 processor, up to 16 devices can be connected. uniVision Software, which is preinstalled on the control unit, is used for image evaluation. Interfaces and Visualization Whether digital IOs, Gigabit Ethernet over TCP/IP and UDP or the LIMA protocol based on XML is required – communication can be implemented with the most up-to-date technologies. Being able to individually configure visualization regardless of the platform is also advantageous for the user. Thanks to the integrated web server, the results can be displayed in the browser of any desired device – regardless of whether a Windows, Mac or Android operating system is used! In this way, for example, users can display camera images, scanned codes and the statuses of inputs and outputs at a graphic user interface. The software is easy to use thanks to free tutorials and templates. It covers a great variety of standard applications with just a few clicks. Thanks to scalable hardware and software, any conceivable settings can be implemented for expert users. Easy Changeover: A Single Software Package, Three Hardware Families uniVision all-in-one software isn’t just compatible with the new VisionSystem2D, but rather with the weQube smart camera and weCat3D 2D/3D profile sensors as well.
