Abstract
A system includes at least two capture devices, each switchable from a respective idle mode to a respective recording mode upon receipt of a trigger signal from a trigger via a network. A controller saves data packets generated by the capture devices during the respective idle modes to a short-term memory, and saves data packets generated during the respective recording modes to a long-term memory such that the data packets form respective saved data streams. The synchronizer sends a sync signal to the capture devices via the network. The compensator determines respective delay periods between sending of the sync signal by the synchronizer and receipt of the sync signal by each of the capture devices, and transfers from the short-term memory to the long-term memory any data packets generated during the respective delay period.
