Likely causes

  • Continuous recording enabled instead of events
  • High bitrate or high resolution profile
  • Too many false motion events triggering clips
  • Card capacity small for the recording profile
  • Card wearing out and remounting repeatedly

Quick checks

  • Check whether recording mode is continuous or event-based
  • Review resolution and bitrate settings
  • Look at how many events are recorded per day
  • Check card health and capacity

Step-by-step fix

1

Switch to motion or person-event recording

2

Lower the bitrate or resolution if quality allows

3

Tune detection zones to reduce false events

4

Format the card in the camera after changing settings

5

Replace with a high-endurance card sized for the new profile
