High-Resolution, High-Speed Imaging: The Latest in Machine Vision Cameras
Modern machine vision cameras offer enhanced resolution and frame speed, enabling greater accuracy and advanced capabilities through 3D measurements. However, a significant challenge lies in efficiently transferring high data rates to frame grabbers and processing systems.

Camera Link has made strides in boosting data rates, but at the cost of expensive cables with limited reach (typically under 10–15 meters).

CoaXPress: A Cost-Effective Solution

The latest interfaces like CoaXPress address these issues by drastically cutting cable costs—up to 98% for high-data-rate scenarios. This technology supports data rates exceeding 4 Megapixels at up to 180 fps, making it ideal for complex machine vision tasks.

Real-World Examples

A customer using more than 15 cameras (each with a resolution of over 4 Megapixels) saw CoaXPress eliminate the need for multiple cables. Instead of requiring 60 Camera Link cables at maximum speeds and lengths, they now use simple coaxial cables—a huge cost and space-saving improvement.

Versatility Across Applications

CoaXPress is particularly appealing in outdoor applications—defense, surveillance, security, and traffic monitoring (e.g., license plate recognition)—where long-distance signal transmission is critical. It seamlessly integrates with existing coax cable infrastructure for upgraded systems.

USB3 Vision: An Emerging Option

Another promising interface is USB3 Vision, based on the USB 3.0 standard. Although it aims to become a machine vision standard, feedback suggests it’s not yet fully mature enough for high-end applications like inspection and metrology equipment.

Cost Efficiency Matters

Both CoaXPress and USB3 Vision tackle cost problems in high-speed systems. The choice depends on your specific needs—each offers compelling benefits tailored to different scenarios.
