Estimated Storage:
  • 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
  • At 3 - 5 frames per second recording you will not miss any activity (remember this is per second)
