🕒 NTP Server Configuration

Accurate time synchronization is critical for security. It ensures that event logs, video playback, and alarm triggers are perfectly aligned across your devices and the cloud.

Why Time Matters

If your device time is out of sync, your video evidence may be inadmissible, and alarms might appear in the wrong order in the Talos CMS.

📱 Manufacturer Specifics

Hikvision / Dahua

• Port: 123 UDP.
• Tip: Stop recording temporarily before making manual time changes to prevent timeline corruption.

Teltonika Routers

• DNS Rebind Protection: Must be Disabled in the router's DNS settings to allow the resolution of the nxgen.cloud domains.
• Interval: Set to 60 minutes for optimal balance between accuracy and network load.

🛠️ Troubleshooting

• Sync Failed: Verify your firewall allows outbound traffic on Port 123 (UDP).
• Off by 1 Hour: Ensure Daylight Saving Time is enabled on BOTH the hardware and the GCXONE dashboard.
• Manual Drift: If the clock drifts significantly, reduce the sync interval to 1800 seconds.
