Can anyone tell me if I can add an external webcam to smarthings?
Yes, I use the Samsung Smartcam. Works great, however, we use the Samsung app…more features. There are several compatible webcams that stream right through ST.
You can find officially supported cameras here: http://www.smartthings.com/compatible-products
There are a number of other cams that are not yet officially supported but will work. My thought behind it all was get a camera that was supported in case features grew…but use the official app for camera functions.
I will say that whule I use the smartcam app primarily, I did build a routine where ST will record 2 min of video in our nursery if the smoke alarm goes off…it works well.
