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 rack-

mounted 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 earth’s 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.

As an alternative to POE, TIMENET

can be powered by an optional 12V DC

supply (VPSU-12V-U) or a user’s existing

24V AC supply.

TIMENET Applications

With its compact rugged enclosure,

extended operating temperature r ange

and flexible mounting options (including

DIN rail mount), TIMENET is suitable

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

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.

About Time Zones

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 earth’s rotation by

the introduction of leap-seconds at

pre-defined intervals. GPS time

references incorporate this automatically.

Therefor e 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.
