Hand Held Trigger Switch
The Known Problem
In general, when a recording is made using 2 digital systems, it can be very difficult to synchronize the systems due to:
- communication delays which are inherent using all PC operating platforms, including Microsoft Windows, and
- differences between the 2 quartz system clocks. For example, two quartz crystal controlled watches accurate to say 1 second per day, perfectly synchronized at time zero will be out by over 40mS after 1 hour.
The Biometrics Ltd Solution
Recordings made using DataLITE along with another recording system can be very accurately synchronized using the DataLITE Trigger Switch.
This provides timing signals that can be used to correct for small variations in start times and internal clocks between the different units used.
