Considering that DVR and NVR systems should run unattended for months, or years, to allow this to happen in an environment where the veracity of evidential data requires accurate time-stamping is not appropriate.

Many clocks which support network devices, IT servers or workstations are rarely checked after an initial manual setup, and backed-up by a battery-based, clock-calendar programme that has no capacity for negating time drift which can sometimes amount to 1 second per day and perhaps minutes, or hours, over longer periods.

If you were to assume that the little clock on the bottom right hand corner of your screen was inherently accurate you would be sadly disappointed. Network Time Synchronization is important: every aspect of maintaining an IT or security surveillance network requires accurate knowledge of when events have happened. It is the task of the network client (i.e.A Master NTP Server that saves time and money. UTC is effectively a GMT reference time and TIMENET provides this via NTP as a universal reference. Thus TIMENET is a universal solution which can be used anywhere in the world. GPS signals are far less prone to interference than traditional national radio clock signals. GPS is a global satellite system used primarily for position location, using very accurate atomic clock references. TIMENET is NTP-compatible and acts as a time server for any NTP-enabled client. NTP stands for Network Time Protocol and is a universal standard for time synchronisation of computers or other devices on a network. Therefore TIMENET will continuously provide an accurate UTC clock reference automatically. GPS time references incorporate this automatically. UTC time copes with variations in the earth's rotation by the introduction of leap-seconds at pre-defined intervals. Universal co-ordinated time is an official world-wide atomic clock standard for time, agreed by national standards around the world. The TIMENET unit can be positioned anywhere within the 3m reach of the antenna lead, and may be conveniently wall-mounted with the integral brackets supplied. The antenna itself is provided with a self-adhesive surface which can be affixed to any window which has a view of some sky (to pick up the GPS satellite transmissions). The GPS antenna is included with the TIMENET product.

The time server unit is very simple to install and set up. This completes the time server installation.Īny DVR or other NTP-compatible network devices can now be programmed to get their NTP time signals from the IP address of the TIMENET server.

The TIMENET setup program is run on any Windows PC, and the only parameter to set is the desired IP address of the TIMENET device. TIMENET is then connected to the network through its RJ45 connector directly to the CCTV/DVR network using a standard CAT5 cable (up to 100m long). Integral watchdog for long-term reliable operation.Direct network interface for remote siting.Accurate universal atomic clock reference.TIMENET is extremely compact, can be wall-mounted, uses very little power and is less than half the cost of competing solutions. TIMENET integrates the GPS receiver and master NTP clock server into a single device which can be directly connected to the network. For this reason, master reference clocks are normally only used in very high-end installations such as city centres, airports and prisons. Network output versions tend to be even more expensive. 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. 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.

Many DVR products, especially those which are PC-based, have inaccurate internal clocks which drift by many seconds per week. It is crucial that all recordings are accurately time-stamped, especially for evidential purposes. TIMENET provides a low-cost solution to the problem of providing accurate reference time signals for CCTV recording equipment.ĬCTV 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.
