Eufy Cam 2C and Surveillence Station Not Recording all Motion

So I set up my Eufy cam cameras to send recorded video to my Synology DS418 NAS box, but for whatever reason, it’s not recording all of the video that is being recorded. On the Eufy app, there is like 15 seconds of video that was recorded, but when I look on my NAS server there is only 3 seconds. Why?

Any help would be much appreciated.
