Clock Synchronization Interface and synchronize all servers and CAD
workstations work in Co-Hurst with the Master Time Clock (Net clock). This
ensures that each workstation and server provide an accurate time stamp.
Time Protocol (NTP): -
A Network Time Protocol (NTP) server is a reference time server used in a
network for the management of precise time to various system devices. The
server recognizes all Ethernet devices that request a time source and ensures that
the time is distributed properly from machine to machine. In this way every piece
of equipment over the network infrastructure with a time display and Ethernet
connection will remain uniform and match each other. These servers are internal
to a facility and require no breach of a firewall to receive time. When used alone
without a master clock, an NTP server solely conveys time to Ethernet devices.
A Master Clock: -
A master clock, on the other hand, does more than convey time to Ethernet
devices. It also has the ability to distribute time to multiple different clock
systems or retrofit with existing clocks systems through its programmable relays.
In addition, a master clock is capable of scheduling various incorporated systems
to shut on and off at desired times automatically. All settings of the master clock
can easily be configured through an easy-to-use web interface via an internet
capable device. Additional functions do not present in an NTP server include
Daylight Saving Time changes, 12 or 24-hour formats, and the possibility of
adding a countdown feature.
When you put them together?
Aside from their differences, a master clock and NTP server actually have the
ability to work with each other to provide an even better timing solution for a
given facility. When the two are paired together, the master clock will receive
accurate time from the NTP server to distribute to all clocks in its system, while
the NTP server will sync all networked devices to the same time it provides for
the master clock. Combining both the capabilities of a master clock and an NTP
server ensures that every clock, computer, printer, and any other device with an
Ethernet connection will display the exact same time, all while having the added
features of a master clock.
Real-Time Mapping: -
All aspects of a CAD system must be optimized for rapid response time and
system reliability. Since time is of the essence, the CAD system must accurately
provide a data and time stamp for every activity. CAD systems collect the initial
information for an incident and then provide the information to one or more RMS
systems.
Logging: -
CAD will log all actions including security violations and attempted breeches,
errors, changes, and updates. Logs should be viewable and searchable by the
system administrator.
