Have you considered using other cameras? Samsung has it’s own brand which I believe also works with SmartThings.
You can look at Foscam. It’s not going to work directly with SHM but it can armed/disarmed through SmartThings, you’ll get a motion detected notification through SmartThings and video recordings can be stored locally on the camera, on a personal server or uploaded to the Foscam cloud (not on ST).
You can use Blink cameras through IFTTT to get motion notifications/arm/disarm them and use the Blink app to view the recordings.
