NTP, Time Zones, and Why Recording Timestamps Matter

Before blaming VMS gaps, verify Stratum sources, firewall rules, and DST policies—time drift breaks investigations.

Accurate timestamps tie card access, ANPR, and video together. If cameras sync to different sources, incident reconstruction becomes a nightmare. Configure NTP to redundant internal stratum servers or vendor-approved pools, not a single consumer router.

Firewall paths

Allow UDP 123 (and any modern alternatives your standard uses) from the CCTV VLAN to the time source. Blocked NTP often fails silently for days.

Documentation

Record the configured timezone versus UTC expectations for SOC teams. DST jumps should be tested annually.
