@Wildcat_1 might have some insight on if any parts of SMD can be used outside of with Dahua NVRs. The feature that lets you quickly search through recordings seems like it would have to require a Dahua NVR, but I'm not sure if SMD can trigger recordings on VMS like
Blue Iris.
None of my cameras have SMD, but my 5442s have SmartAI which adds filters for humans/vehicles that can be enabled in IVS rules. That's been working great for me on Blue Iris.
