The old surveillance systems just won't cut it anymore.
To be fully secure, you need Internet-based protection.
Q:
We've been looking into security systems for our business.
Are there Internet-based, streaming video surveillance
systems that we should explore as well? If so, how do they
work?
A:
You're not alone--many organizations today want to shore up
the safety and security of their employees, visitors and
students as well as their premises and assets. Policing
personnel often are just too expensive an alternative. So
businesses are seeking innovative, affordable alternatives
that deliver a rapid and appropriate response to crimes or
emergencies that may arise.
For
years, organizations installed closed circuit TV (CCTV)
almost exclusively for security monitoring. CCTV, though,
has many shortcomings. First of all, it's expensive and
disruptive to install. Second, once installed, its
capabilities are limited. CCTV records images on
videocassettes, so police and other emergency personnel
can't view the event live. Therefore, they often don't know
an emergency is occurring or how serious it is. If they are
informed of an emergency, these first responders can't
understand its circumstances or context through CCTV. They
see the event only after viewing the video, which is usually
long after it's over.
In
some cases, authorities can't ever view the event. Savvy
criminals often take the tape with them as they leave the
scene. In cases of fire, it's frequently burned. Therefore,
a successor system is needed--one that delivers secure,
real-time images of an emergency as well as the flexibility
to show both full-motion and still images.
More
and more, companies are installing Internet-based IP
surveillance as a far superior alternative to CCTV. This
technology offers real-time delivery of video and still
images from a crime or emergency scene via a LAN or the
Internet.
In a
nutshell, IP surveillance uses a company's existing network
and Internet technology to transmit images from analog
cameras and/or IP cameras over public networks. These
systems allow live streaming video and still image transfer
(both one-way and two-way) at an average of 30 frames per
second into a standard, easy-to-use Web browser, so video
can be viewed in real time
from police cars and other emergency vehicles.
IP-based systems deliver a great deal of additional
functionality. For instance, they provide motion detection,
auto time and date stamps, easy transfer of visuals, and
pre- and post-alarm messaging. Business owners are notified
immediately if an event is occurring; they can then log on
to the system remotely to see what's happening in their
offices and businesses.
An
enormous variety of organizations have already installed
IP-based surveillance systems to help secure both the
interior and exterior of buildings. A few examples include
retail stores, banks, law firms, gas stations, parking
garages, schools and government offices; but these systems
provide greater security to all organizations and
businesses. Users have found that IP surveillance:
-
Enhances and expedites law enforcement and emergency
services to high-risk calls.
-
Contributes to reliable identification of criminals and
reduces the need for eyewitnesses.
-
Can
be used locally and remotely.
-
Integrates easily with CCTV cameras, thus preserving
existing security investments.
Most
users also have discovered that IP surveillance is very
affordable, since companies already have many components of
the system in place (such as an IP
network and broadband connectivity). Other system components
include an 802.11 wireless LAN, an access router, a video
server, an IP camera (existing analog cameras can also be
used) and host PC surveillance software.
IP
technology is the next step forward for surveillance
systems. IP-based streaming video surveillance lets
organizations monitor, prevent and/or respond to emergency
situations more effectively and affordably, via the
Internet. At the same time, the technology allows law
enforcement, security companies and other emergency
personnel to prepare better and respond more fully to
emergencies. Thus, the physical safety of a company's vital
human and business assets is far more secure and protected.
