I'm getting more down on the new improved AI detection. I erased all of the IVS setup and started over after a reboot to see if that would help. Occasionally the IL will detect better than the S3, but the odds are definitely in the S3's favor. I caught some obvious IL failures:
This one it never detected:
For these it took about a minute to make up it's mind that there was an animal there:
The camera is running the latest IL/PRO firmware and I'm reluctant to try an older version over fear of bricking.
I tried a while with the large scale models off. I'm suspecting that the switch is a placebo, just like the Object Filter switch is in the 5442s and some other models.
