Precautions on changing system time

•

The SuperDVR system provides the retrieving mechanism for video files, which must take 
the system time as a retrieving reference. To change the computer time after installation 
will create a high risk of wrong time reference. 

•

Before SuperDVR is used, it must be confirmed whether the current computer time is 
correct.

•

Deactivate computer auto time updating function of system.

•

Make sure the motherboard of the computer is in normal state.

If system time must be changed, please do following preparations first
If new time is later than current computer time (for example, change 2006/01/01 0:0:0 
(current system time) to 2007/01/01 0:0:0 (target time)), the change can be made directly.
If new time is before the current computer time (for example, change 2007/01/01 0:0:0 
(current system time) to 2006/01/01 0:0:0 (target time)), first stop the video recording, backup 
all video data. Turn off SuperDVR, change computer time, and re-start SuperDVR.
