Multi-Camera Time Synchronisation

Short answer

Multi-camera analysis depends on a documented common time basis so interval outputs and cross-site observations can be compared or matched accurately.

Before the project starts

• Confirm time zone and clock source for every camera.
• Check start/end coverage and any recording gaps.
• Define the accepted alignment tolerance for the project.

Practical approach

Create a coverage record before processing. Where clocks drift or timestamps are uncertain, record the limitation and apply only an approved correction method.

Checks and limitations

Compare identifiable common events or approved reference points where they are available, then test interval continuity across sources.

Uncertain clock alignment can weaken movement matching and should not be hidden in final tables.
