Yes! That is exactly why we don't use MD/SMD. IVS has been found to be more reliable.
@bigredfish so I mirrored the settings you have on the storage/record (see attached). Although on the record schedule after I click on intelligent and save it, it always reverts back to the general box but not sure if that matters.
Also I managed to get the notification working on my phone, I realised that the motion detection had a schedule set as "custom" so I changed to full time which may have solved the issue.
So the way I understand it is that SMD will pick up the whole camera view and MD will base it off the selected area, is that correct?
I turned off SMD and just used MD with a set area but realised it gives a lot of false negatives picking up car headlights, shadows, birds flying pass. Is this where I need to switch to IVS to get better results?
