2k Battery Doorbell playback

Hi all, I have just added the 2k battery doorbell to my system which already has 2 eufycam 2 cameras on it. The cameras are working absolutely spot on but I am having issues with the doorbell being really stop start when playing back the footage of the motion detection. Everything else works fine. I have searched on here for an answer but didn’t see anything. Any help would be appreciated, many thanks, Rob.
