Reality: In addition to people perceiving digital video
recorders to be latest and best technology, many people also believe
that the DVR is an all-digital networked technology—it is not.
A DVR does have a lot of advantages compared to a VCR (video
cassette recorder): no need to change tapes, consistent image
quality, and quicker search capabilities. But you still have all
those analog cables, which first of all can distort image quality,
but are also very expensive to run throughout a facility. IP-Surveillance
has all the advantages of a DVR and many more:
•
Scalability. IP-Surveillance scales from one to thousands of cameras
in increments of a single camera. There are no 16-channel jumps like
in the DVR world. IP-Surveillance offers any frame rate for any
camera at any time—no limitations.
• More cost efficient infrastructure. Most facilities are already
wired with twisted pair infrastructure, so with IP-Surveillance no
additional wiring (a major expense of a CCTV install) is required.
Only one type of network (IP) connects and manages the enterprise
for data, video, voice, and others—making management more effective
and cost efficient.
• Remote accessibility. Any video stream, live or recorded, can be
securely accessed and controlled from any location in the world over
wired or wireless networks.
• Intelligence at camera level. Motion detection, event handling,
sensor input, relay output, time and date, and other built-in
capabilities allow the camera to make intelligent decisions on when
to send alarms and to whom, when to send video, and even at what
frame rate or resolution to send the video.
• Lower system cost. For many installations, the IP-Surveillance
system has proven to be a lower cost alternative. Open and standard
network, server and storage equipment enables market competition
between choices versus the single vendor locked-in approach of a DVR.
And that’s just hardware—add lower installation and maintenance
costs and all the performance benefits, and it’s clear IP-Surveillance
saves substantial sums.
Contrary to some popular opinion, the DVR is not an end-point
solution, but rather one milestone in the continuing development of
CCTV technology. As the marketplace assesses DVRs more carefully, it
is emerging that the DVR represents outdated, solution-in-a-box
thinking. IP-Surveillance technology has quickly proven to be
superior to DVR technology. There is an enormous difference between
the two technologies and the marketplace is only just beginning to
understand this critical point.
