TIMENET is a low-cost solution for
accurately synchronising computer
system clocks
TIMENET offers a solution to the problem of providing accurate, reference
time signals for any Ethernet network, especially closed networks.
Time Synchronisation
Many network installations require a
reference time signal for synchronising
system clocks to ensure they are always
set precisely to the correct time. For
example, it is crucial that all CCTV
recordings are accurately time-stamped,
especially for evidential purposes.
Most Digital Video Recorder (DVR)
products - especially those which are
PC-based - have inaccurate internal
clocks which can drift by many seconds
per week. Considering that DVR and
NVR systems should run unattended for
months or years, the time settings can
end up being in error by many minutes.
Further, multiple recorders and devices
will drift apart time-wise, reducing the
veracity of evidential data.
Compact Solution
Whilst traditional solutions involve
atomic clock radio receivers or GPS
sensors linked to an expensive rackmounted master clock server, TIMENET
integrates the GPS receiver and master
NTP clock server into a compact device
for direct connection to the network.
TIMENET can be wall-mounted, uses very
little power and is less than half the cost
of competing solutions. TIMENET can be
powered over the network by POE, or
locally by a low-voltage power supply.
Browser Interface
TIMENET provides a simple browser
interface for setting up the IP address
and configuration password.
The status tab displays information
such as system up-time, GPS lock, UTC
and local time, plus an extremely useful
satellite signal meter. This meter shows
satellites in view, signal strength and
highlights in green all those with a strong
signal level.
Example 1. A simple browser interface shows the status of the system, with
separate tabs for settings and administration.

What countries can I use TIMENET in ?
As TIMENET is GPS based, it can be used anywhere on the earths surface.
Installer Friendly
Simply connect the antenna to the
TIMENET and the TIMENET to your
POE network switch. Configure the IP
address via the easy-to-use browser
interface and the TIMENET installation
is complete.
The supplied antenna includes a 5 metre
cable which can be further extended by
optional 10 metre cables (VTN-EXTEND)
and is provided with a self-adhesive
surface which can be affixed to any
window which has a view of the sky.
The standard antenna is also rated for
external use and so can be externally
mounted on a roof, window sill or wall etc.
for a wide range of applications and
environments.
Security
related
applications include time synchronisation
of DVR and NVR servers, access
control servers, operators workstations,
and even IP cameras. More general
applications include time-synchronisation
of Windows, Mac & Linux PCs and servers.
The availability of full GPS data to
third party applications also makes
TIMENET ideal for mobile or vehicle
based systems.
About GPS
As an alternative to POE, TIMENET
can be powered by an optional 12V DC
supply (VPSU-12V-U) or a users existing
24V AC supply.
GPS is a global satellite system used
primarily for position location, using very
accurate atomic clock references. GPS
signals are far less prone to interference
than traditional national radio clock
signals. Thus TIMENET is a universal
solution which can be used anywhere in
the world.
TIMENET Applications
About Time Zones
With its compact rugged enclosure,
extended operating temperature range
and flexible mounting options (including
DIN rail mount), TIMENET is suitable
UTC is effectively a GMT reference time
and TIMENET provides this via NTP as a
universal reference. It is the task of the
network client (i.e. DVR or other client
device) to look after the local time zone
setting for the country or zone location,
including any local or national variations
to daylight savings time or equivalent.
About UTC Time
Universal co-ordinated time is an official
world-wide atomic clock reference for
time, agreed by national standards
around the world. UTC time copes with
variations in the earths rotation by
the introduction of leap-seconds at
pre-defined intervals. GPS time
references incorporate this automatically.
Therefore TIMENET will continuously and
automatically provide an accurate UTC
clock reference.
About NTP
NTP stands for Network Time Protocol
and is a universal standard for time
synchronisation of computers or other
devices on a network. TIMENET is NTP
compatible and acts as a time server for
any NTP-enabled client. All Windows,
Linux and Mac OS operating systems
are NTP compatible.
