Video recording length not as set

[Byron Cam_714519239041239]

On the App I have set my camera (E1 Pro) to record a duration of 1 minute post trigger event but all the recordings stop within at the most 20 seconds of the recording triggering, sometimes as little as 5 or 6 seconds, sometimes cutting off before the pet subject has moved out of view. I've tried changing whether or not the video will be attached to the email sent to me with no difference. If it helps the recordings all seem to max out at just under 1Mb.
Will this improve if I put an SD Card in so it's not just relying on internal memory (1Mb?) then sending to the (Free) Reolink cloud account or does anyone have any other advice that might help?

Put in an SD Card.
