If you've signed up for Cam Plus Lite and assigned your cameras then you shouldn't have to do anything further to receive Event videos (12-second video clips).
However, if you do not have Cam Plus Lite (or Cam Plus, or Cam Protect) you will only receive thumbnail images when you have Event Detection enabled.
