Where is Vistacam SD for UI5 and motion detect apps?

I have a Foscam FI8910 and have been using the Vistacam PT&HD 1.1 plugin (3866) very successfully. I want to add motion detect.

Looking at the forums, says it should work, but I don’t have I_VistaCamMS.xml. I figure my version is too old.

Where is the latest. I can’t find it on the App Store?
