4) Recovered File (blue):
Recovered File is generated once the NVR server resumes working once the
power electric back. This is special unique and advanced feature of NVR.
For an example, when the premises was broken into and the main power
switch was cut, there was a period of critical time of recording files were
captured by IP camera but it was not insufficient time to be converted the
temp video files to be wrote into hard disk drive. Once the NVR server gets
power resume, the NVR is able to generate a so-called Recovered File and
save on hard disk drive. User can then find out the critical evidence clips if the
camera successful captured the scenario.
5) Time Overlap (green):
Time Overlap file is generated once NVR server’s time is changed during
recording task. For examples, using NVR’s built-in NTP server to synchronize a
required time, or alter the NVR server time manually, or change the time zone
and enable daylight saving time.
