Version:
l           iNVS V100R002C01
l           iNVS V100R002C02
Symptoms:
When you use Special Player to query videos, the video (for example, video from scheduled video recording) that should be continuous is intermittent.
Alarm Information
None.
Handling Process
None.
Root Cause
Cause analysis:
1.         Connect an SSH tool to the NVR.
The default user name is root and default password is 123456.
2.         Run the less /hinvs/common/log/NVS_Daemontools.log command to view the watchdog logs.
3.         The time records of the intermittent video shows that the watchdog restarts the iNVS service due to a system time change.
