Modern industrial vision systems often require higher performance, whether it’s through increased speed or greater detail. A multi-camera based system can offer multiple benefits: a broader field of view (FOV), faster throughput, more detailed inspection capabilities, and richer measurement data—often all at once.

Depending on the application requirements, these advantages can be achieved in different ways. For high-speed imaging tasks, a single ultra-high-resolution camera with 25 megapixels might suffice for large FOV needs, while a high-speed camera could meet throughput demands alone. However, combining multiple cameras through a multi-camera system often provides the most efficient path to achieving complex performance goals.

CoaXPress: The Ideal Interface for Multi-Camera Systems

The CoaXPress (CXP) interface standard stands out as an excellent solution for connecting data from multiple cameras. This digital protocol can transmit up to 6.25Gbps over a single coaxial cable, carrying numerous channels of image data and metadata—making it highly scalable.

This capability enables several key advantages:

  • Simplified System Design: Multiple cameras (e.g., four 8-megapixel units) can be synchronized through just one frame grabber interface with dedicated power over the same cables.
  • Enhanced Flexibility: Different camera types, even those operating at varying speeds or using different sensor technologies (CCD/CMOS), can connect to the same system without cable length constraints.
  • Cost Efficiency: The use of long coaxial cables reduces installation complexity and costs.

When Should You Consider CoaXPress?

If you’ve determined that a multi-camera vision system would benefit your application, consider CoaXPress if you face any of these situations:

  1. Need maximum camera bandwidth utilization
  2. Limited cable routing space
  3. Requirement for extended cable lengths
  4. Desire to integrate cameras with different speeds
  5. Plan to mix sensor technologies (CCD/CMOS)
  6. Strict synchronization requirements exist
  7. Planning an upgrade from analog systems
  8. Need a system that avoids overwhelming your PC
