Interval between Motion Alert email images

Hi,

Is there anywhere to set the timeout interval between the motion detection images sent via email?

I currently have a few Hiks connected to a Hik 7608NVR and 1 of the cameras specifically watches the electric gate on the front of my premesis.

Say im coming into my gate i open the gate and the gate sets off the motion alert and emails me 3 images of the gate opening.

Then i drive through it and the gate closes.

Well the next email i get is of 3 images of the gate closing.

i dont get...
