Email alert pre-event

Topology:

DS-7604NI-K1-4P - v3.4.98
3 x DS-2C2355FWD-1 -v5.5.61
1 x DS-2CD2555FWD-IS v5.5.61

I have successfully set up email notifications directly from the cameras and received the three captures for the intrusion and line cross events. The problem is that the first capture is two seconds after the event, thus the action is generally gone. Is there a way to have the notifications (say) two seconds pre-event, event time, two seconds post event?

Thanks
