System and methods for aligning event data recorded by recording devices. Recording devices create, transmit, and store alignment data. Alignment data created by a recording device is stored in the memory of the recording device with a time that is maintained by the recording device and that is relative to the time of event data recorded by the recording device that creates the alignment data.Recording devices further receive and store transmitted alignment data. Alignment data received by a recording device is stored in the memory of the recording device with a time that is maintained by the receiving recording device and that is relative to the time of event data recorded by the recording device that creates alignment data.Stored alignment data may be used to align the playback of event data of devices that have the same alignment data.
