6.20.1 Precision Time Protocol (PTP)
PTP (Precision Time Protocol) is a clock synchronization protocol of IEEE 1588 standard. It allows
to precisely synchronize clocks of multiple GigE cameras on an ethernet network. PTP procedure
establishes that the device with the most accurate clock in the network is elected as grandmaster
clock and other devices becomes slaves. Slaves periodically and automatically synchronize their
clock directly with the master’s clock. The result is that the timestamp values are aligned with the
master over the entire network. This protocol is closely described in the IEEE standard document.
NOTE: Itala cameras can become only slave (master mode is not implemented).
The PTP feature must be enabled if the scheduled action commands are used (6.12.2).
