Time synchronization and other time related issues

Time synchronization and other time related issues

If a network video recorder and attached network IP cameras date/time settings are out of sync, this can cause a number of issues such as not being able to select the proper time for Search playback and backup.  To correct time synchronization issues, try the following:

  • Many times the network video recorder does not sync time properly with attached network IP cameras because the firmware is out of date.  Update to the newest firmware available for both the recorder and the cameras.
  • If firmware does not resolve the issue, turning off NTP on both the video recorder and cameras and using the sync to PC option is suggested.  NTP can be either found in the Network or Date/Time settings on the devices.  Sync PC setting can be found in the Date/Time settings on the devices and is also accomplished by using the Config Tool.  If NTP is preferred, make sure that NTP is enabled on ALL devices.
  • Check to make sure the daylight savings time (DST) settings are correct on all devices (located in Date/Time settings).

If the unit or camera is gradually losing time, try updating the firmware.  Regardless of the refresh time set, NTP will only mask the issue if the unit is defective.  Contact technical support if firmware doesn’t correct the issue.
