Issue
When exacqVision Server connects to an IP camera, it normally configures the camera with the IP address of an NTP time server, so that the camera will automatically keep time synchronized. Normally, cameras will then enable sync.
However, some ONVIF cameras, such as Honeywell H3W2GR1 or Tyco Security Products Essential 4, do not automatically enable sync. As a result, video timestamps may inadvertently drift.
<br>
Workaround
Check the camera’s web interface, to verify whether NTP sync has been enabled, and if not, to manually enable it.
<br>
Resolution
Beginning with 20.03.118, exacqVision Server now enables NTP sync as a precaution.
