PL-X Cameras


Description:


FEATURE_PTP allows 2 or more cameras on the same network, to synchronize their clocks to a ‘Master’ clock using the IEEE1588 / PTPv2 protocol. Pixelink cameras are capable if becoming the master clock on the network, as negotiated via the PTP protocol. An application gets timestamps from a cameras clock via the function PxLGetCurrentTimestamp. What more, a camera timestamp is also returned in the descriptor of each frame received, and with certain other operations, such as event callbacks.
