IEEE1588 Simplifies Camera Synchronization

Traditionally clocks built into cameras are reset when the power is switched on, and the time stamps asynchronously commence a count-up. For networked cameras, these time stamps gradually go out of synchronization as time passes owing to discrepancies in the clocks’ frequencies.

IEEE1588 is a protocol stipulated by the Precision Time Protocol (PTP) and is in effect for equipment connected together by Ethernet. It synchronizes the time with extremely high levels of precision in cameras that are connected via an Ethernet cable to a “Grand Master” standard time clock.
