I currently have the Samsung SmartCam HD Pro - which works with ST, but doesn’t really do much. But it works fine.
I also have the Samsung SmartCam HD Plus - which doesn’t work with ST and is honestly not any different than the Pro, other than it’s smaller and black.
I also have 2 Samsung SmartCam HD Outdoor - these are terrible. Given me nothing but problems, constantly disconnecting from my network. I’m actually getting rid of both as soon as possible.
Also, the Samsung SmartCam app is terrible. Crappy interface and not easy to work with. One slow-loading stream at a time.
Right now, I’m probably going to get rid of all of them and chooser a Blink setup (love that it integrates with ST) or Netgear Arlo (love that it’s got nightvision and outdoor rated).
Ultimately though, I’d pick the camera that works best for you, regardless of ST. None of the integration with ST is all that valuable. All ST can do is tell most cameras to grab a clip when SHM is triggered, from my experience.
Do you need nightvision? Do you need 2-way audio? Out of your other considerations, you’re going to use the camera’s native app for almost all of those features. And any decent indoor cam from Nest to Samsung or Foscam, etc - will provide the same service.
