HD-SDI Technology
Safe and secure
HD-SDI products are based on existing television and
broadcast standards. All products that meet these standards
are compatible with Grundig HD-SDI systems, without
needing further integration.
As part of the HD CCTV Alliance, Grundig is contributing to
the development of the HD-SDI standard within the vid-
eo surveillance industry. Further developments include
increasing transmission distances, increasing transmission
resolutions and implementing features such as serial
communication and power over coaxial cable – all of which
will be included in the standard.
Unlike ONVIF, which has been developed specically for IP
security applications, the SDI standard already exists.
It is simply evolving and adapting to suit video surveillance
applications.
Compatibility
HD-SDI systems are connected point-to-point, not over a
network. Firewalls and other network protection
hardware are not necessary to ensure the safe running and
operation of the system, as it is intrinsically safe.
Stored data is also secure. If you use a HD-SDI DVR without
network access, the only way to see the
video is by getting physical access to the device.
IP cameras in public areas might be a security risk
for your network. An HD-SDI camera is not!
Coaxial cabling is used to transmit HD-SDI signals, just like
in analogue systems.
No network conguration or IT knowledge are necessary to
set up a system. The DVR will detect the video signals from
the cameras automatically and will record the data
immediately.
Existing analogue coaxial cabling can be re-used for HD-SDI
systems, saving on installation and cabling costs.
Plug & play
HD-SDI signals can be transmitted over standard coaxial
cable.
The HD-CCTV alliance makes sure
all products work together.
