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.
