This seamless integration and matrix functionality is achieved
thanks to the SeMSy technology developed by Dallmeier electronic and
used by the DIS-1 devices. SeMSy supports the easy handling and
switching of different data streams (e.g. audio, video, control)
with the result that you can display and record live pictures
anywhere in the networked system; you can record locally and/or
centrally on a server; and you can watch live video pictures at
different places (for example in different control centres) at the
same time. In contrast to traditional analogue matrices which are
only accessible at a particular location and have a limited number
of inputs and outputs, the virtual matrix generated through the co-operation
of SeMSy and the network, can have any number of extra components
added anywhere on the network. Hence this kind of digital network
offers significantly greater flexibility and expandability for
future requirements.
In addition to live displays, the system has ring buffers recording
full picture quality pre-alarm histories. Video sequences can be
permanently archived onto DVD to remain available for future
processing, and, for ease of analysis, video sequences can be
replayed in many different modes: forwards, backwards, in slow
motion, speeded up and freeze-frame are all possible. The camera
pictures can be selected by mouse click from a site plan which is
based on a standard graphic format so that it can be produced direct
from design office CAD drawings. Security-relevant conditions such
as a camera failure are indicated on the plan with a flashing symbol.
The system allows you to pre-define procedures for camera switching
which it automatically actions as a virtual guard tour at the click
of a mouse. Thanks to the open, freely scaleable system architecture,
the use of standard interfaces and the systems flexibility and
adaptability, new expansions and developments can be integrated
easily and seamlessly into the solution at any time. This ensures
that the system is ideally positioned to meet all future
requirements and constitutes a perfect basis for professional, easy
to use systems for complex security projects. Dallmeier electronic
provides support for the planning phase to ensure all the sub-systems
co-operate well with each other.
