The VeriLook SDK enables face identification on Linux or Windows with most cameras, webcams and databases. It processes and identifies up to 80,000 faces every second, including multiple faces simultaneously.

The SDK distribution package includes a VeriLook DLL (with one license), an interface for image input from files and cameras, and Windows source codes for DLL usage sample applications in various programming languages, such as C/C++, C#, Java, Visual Basic 6, and VBA for MS Access. Additionally, the package also includes Linux source codes for library usage sample applications in C/C++, as well as SDK documentation.
Overall, I found the SDK to be a powerful and practical tool for face identification, with robust capabilities and easy-to-use interfaces. If you're interested in learning more, I highly recommend checking out the developer's website or contacting them for additional information.
