  • Page 137: Smart Features And The Smart Features Framework

    Features Framework 6.1 What are Smart Features Smart features are features unique to Basler cameras. Test Images, the Cycle Time Stamp, and the CRC (Cyclic Redundancy Check) Checksum are examples of Basler smart features. In some cases, enabling a smart feature will simply change the behavior of the camera. The Test Image feature is a good example of this type of smart feature.

  • Page 138: What Do I Need To Use Smart Features
