For those who have tried this and succeeded in going to get some help:
Does the camera need an SD card to work like this?
What are the setting you have "capture parameter" screen (next one over from the above screenshot)
What do you have set up for the linkage on the line crossing alert on the camera and on the NVR?
I gather the NVR does the email sending and not the camera itself. Is this definitely the case and do you have your cameras plugged directly into the NVR or can they access the internet independently?
