5 GigE Basics
Broadcast
A
broadcast
is a data packet that is transmitted to all stations on a network. This is done by
sending a data packet to the reserved IP address .255 of a network or subnet (broadcast address).
Heartbeat
Network devices send a
heartbeat
to signal that they are operational and fully functional. If this
heartbeat signal is not detected, the recipient system assumes that the remote device is no longer
available.
Paired
Paired
describes the logical connection of a network camera and a host PC. When a camera and a
host PC are paired, they are exclusively connected. Simultaneous pairing with several host PCs is
not possible.
A request for image data is only possible in paired state.
