The security industry
goes digital!
Digital Video Recording is now well accepted as the
recording method of choice, offering much more than
just the well known benefits of improved constant
recording quality, lower maintenance, such as valuable
time and cost savings through the added efficiency
offered by digital systems.
Advances in compression and storage devices means
that compact units are available for storing and archiving
the recordings in much less space than was needed with
conventional tape based systems.
Remote access over public or private data or telephone
networks, or even the internet means that you can access
live video and recordings from wherever you want and
whenever the need arises.
