How many days of detection-based recordings fit on an SD card or a hard drive (if detection occurs 50% of the time)?

If you use the recordings based on the work of a detector, then you can store a lot more recordings on your card or drive.

On average, if there is a periodical movement triggers during the day and no movement during the night, the amount of recording usually rounds up to around 50% of all time passed.
