Master NTP Time Server

TIMENET Pro - Master NTP Time Server

TIMENET Pro is a Master NTP reference clock for Ethernet networks


TIMENET Pro is an accurate, low cost, extremely compact universal atomic clock reference for network time synchronisation.

CCTV and digital video recorder (DVR) installations require accurate reference time signals for synchronisation of system clocks to ensure that they are always set at the precisely correct time. It is crucial that all recordings are accurately time-stamped, especially for evidential purposes. Many DVR products, especially those which are PC-based, have inaccurate internal clocks which drift by many seconds per week. Considering that DVR systems may be left unattended for months on end, it is easy to see that the time settings can end up being in error by many minutes.

TIMENET Pro Master NTP Server

 

TIMENET Pro is a low-cost solution for accurately synchronising computer system clocks Time Synchronisation Most network installations require a reference time signal for synchronising system clocks to ensure they are always set precisely to the correct time. 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, or even hours. Further, multiple recorders and devices will drift apart time-wise, reducing the veracity of evidential data.

TIMENET Pro can be wall-mounted, uses very little power and is less than half the cost of competing solutions. TIMENET Pro can be powered over the network by POE, or locally by a low voltage power supply.

Browser Interface TIMENET Pro provides a clean and 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, and their signal strength.

Installer Friendly Simply connect the antenna to the TIMENET Pro and the TIMENET Pro to your POE network switch. Configure the IP address via the easy-to-use browser interface and the TIMENET Pro installation is complete. The antenna that is supplied with the unit includes a 5 metre cable. This can be extended further by adding an optional 10 metre long cable (VTN-EXTEND). The antenna has a self-adhesive surface which can be fixed to any window which has a view of the sky.

About UTC Time

 

Universal co-ordinated time is an official world-wide atomic clock standard 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. Therefore TIMENET Pro will continuously provide an accurate UTC clock reference automatically.

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 Pro is NTP-compatible and acts as a time server for any NTP compatible device.

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 Pro is a universal solution which can be used anywhere in the world.

About Time Zone

 

UTC is effectively a GMT reference time and TIMENET Pro 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

The traditional solution to providing an accurate reference time has been to use an atomic clock radio receiver or GPS sensor linked to an expensive rack-mounted master clock server, typically with serial-only output. Network output versions tend to be even more expensive. For this reason, master reference clocks are normally only used in very high-end installations such as city centres, airports and prisons. TIMENET Pro integrates the GPS receiver and master NTP clock server into a single device which can be directly connected to the network.
