Calculate your recording time.

Enter the number of hours (1 to 24) per day that motion or AI detection will detect events on your system per 24 hour period.

As a guide we would expect a house on a quiet road to have movement or AI detection trigger recording for 8 to 12 hours a day. A business open 9am to 5pm, 5 days a week and on a busy high street would trigger recording 16 to 20 hours a day.
