The Smart Detection Events AND the Smart Events Notifications toggles features you noted are available on multiple different cams. These features were added through a Production Firmware Update. The Pan V1 and V2 were the first to get this a long time ago.
It is being added to each cam as it is being programmed into the firmware release for each.
The V3 cam DID get this feature upgrade in a Production Release Firmware Update on October 14th. It was released in both 4.36.10.2700 and again in 4.36.10.2864. However, BOTH of those releases were halted soon after released because of unrelated bugs that needed to be fixed.
This feature is also available in the current Beta Release Candidate build 4.36.10.3346 that is undergoing final testing now for any Beta Tester who wishes to install it. I have 6 cams running .3346 and 8 cams running .2864. All have the features.
These features will be in the next V3 Firmware Production Release.
