Setting up motion event settings - NVR or IP Cam? (SOLVED)

Hi,

After updating to 4.00+ FW, and updating cameras, I have noticed there are motion setting options on the cam IP page that there isn't on the NVR e.g "Expert" Motion settings which allows you to customise a box area with sensitivity and percentage.

My questions
1)Do the settings made on the cam IP web portal trump the settings on NVR web portal?
2)Should I be setting up motion /events on each cam IP web portal separately or NVR web portal?
3)If I should be setting up motion/events on...
