What does no record file mean?

Question:

I am trying to access my playback but it says no record file found. What does that mean?

Answer:

This means that the footage is no longer there. Either because it has been recorded over or because it was not saved to the correct date. To verify this, check your recorder's date and time. If the date is incorrect then you will need to search for the playback on the date the recorder would have saved it to.
