Hello,
I'ma C/C++ Windows systems engineer who provides systems integration services, including Wrapper DLLs to wrapper around C SDKs such as this Opticon SDK, and expose them to Delphi, VB, C# etc.
I've taken a look at it and it seems relatively straight forward, to create a DLL that your Delphi code can call, to utilise the SDK exposed inthe .LIB static library, provided in the SDK.
Only issue is that you can't expect developers to have these sorts of custom devices in their homes !? :) and I certainly don't have one.
If still interested, do send Me a message.
Cheers
D
