User can calculate and estimate record hours by below formula 80G Byte @ 7 frames per second @ Normal quality
1 frame per second is the lowest frame rate recordable and 30 frames per second is the maximum which is real time.
There is no real need to record in real time unless there are regulatory reasons as in case of government facilities or casinos .
Recording at 1 frame per second is what traditional analog systems record .
You can always rewind in high speed so the lower the frame rate the faster it is to playback an entire day.
At 3 - 5 frames per second recording you will not miss any activity (remember this is per second).
