Video clip notifications are offered as an optional premium feature

I noticed this comment on page.
What does it mean? I need to pay for this to work?

I think it may be referring to the SHM integration and some of the SHM features are a monthly subscription feature.

I didn’t realize the paid video storage for SHM had been released .

I don’t like it, where it is going. They may force user into subscription model for almost everything, as I don’t see they have much revenue options. I was shocked to read this and backed away from buying there cameras. Now going to go back to cheaper cameras with own app (which is a mess and that’s why both ST), but ST seems to be going to a path of paid service themselves.
