ST things integrations is limited. The Samsung smartthing pro is what I use.
- 4 outdoor cameras continuously recording to a base station
With Blue Iris installed on a machine you can record to the computer. I have found n NVR option for these cameras
- If any of the cameras detects motion then a phone notification is raised
The Samsung app will notify of any Alerts
- Can see video streams for the cameras from phone
Yes , same app allows streaming and recording of events to a SD card
- Integrates with ST, so can turn off alerts if we’re home for certain cameras (optional)
Nativity integrates to ST
Alternatively , Foscam has a few options with some Custom DTH code for ST integration. They offer a NVR but BI works the same. Foscam App does alerts and live streaming. Cloud storage as well. I tested an R4 camera but found the App slow to connect. No app SD card access.
