Me, Hans-David Alkenius, the author of this component, created the TCamRemote component in 2005. The idea, at that time, was to create a component for Delphi to create an application for Canon cameras remote handing. The application was shortlived, but the component remained and has been developed and improved since then.
I live in Linköping in Sweden and use my spare time to maintain TCamRemote. Do not hesitate to drop me an email if you want help with Canon camera integration. I have more than 15 years of experience.
More details about TCamRemote can be found in the opnline PDF manual that can be downloaded from this page.
