Short answer, yes, you will be frustrated, but not because of the blink cameras. Because anybody trying to use SmartThings for security is going to be frustrated to some degree.
When smart things works well, it is absolutely my favorite home automation system. But it has ongoing issues with reliability, so that something that has worked well for months will suddenly stop working even though you didn’t change anything at your house. This happens every few weeks. It’s not that every customer is affected every time, but rather that many customers are affected several times a year. And that just doesn’t meet most customers expectations of a security system.
Here’s a current thread, but there are many others:
As far as the blink cameras, if you’re willing to pay an extra $10, there’s a nice custom app that you can add that has many features. It’s quite popular. But it’s still not going to work quite the way you expect. ( The “official” in the following description means that blink has blessed this integration, it’s not actually official from the SmartThings side.)
I’m tired now, so I will leave it to others to discuss.
