Video Surveillance 101
|

| Video Surveillance
is a collection of composite video cameras
used for monitoring and surveying in areas for
reasons of security. It differs from broadcast
television in that all components are connected
directly to a monitoring station and/or recording
device. Most Common means of communications for
systems are: Coaxial Cable, UTP (Unshielded Twisted
Pair), RF Wireless, and Fiber Optics. Replacing
the time lapse video recorder, it is standard
practice to use Digital Video Recorder Technology
as a means to archive camera area views. Using
improved data storage compression and built-in
motion recording, DVR's are affordable and capable
of providing long term storage. Cameras may come
in a wide variety of options, including but not
limited to: Pan/Tilt/Zoom, Infra Red, Low-light
Sensitive, High Definition, Miniature (Covert),
Ruggedized (Vandal, Weather, Ballistic, Intrinsic,
etc.) |

Video Surveillance
is often used in areas where there is an increased need
for security, such as banks, casinos, hospitals, shopping
malls, airports, and the government/military. Video
Surveillance has developed to the point where it is
not only used in commercial, industrial, and military
applications but home security systems as well. |

High Definition
Cameras that can take 1280x720 pixel
resolution images of the camera scene and record
using a network video recording solution. The
uses of high definition color cameras provide
extremely fine detail in observation and playback
through software. |

|
License Plate Capture
Cameras, linked to an OCR (Object Character
Recognition) produces a potential source of information
on the location of persons or groups. This may
provide identification of an undesirable immediately
upon entrance to a premise. |

 Facial
Recognition technology has been tried
as a form of mass surveillance. This type of system
has generally been proposed to compare faces at
airports and seaports with those of suspected
terrorists or other undesirable entrants. This
technology makes it possible to determine a person's
identity without the need to stop and ask them
in the street, or even alert them that their identity
is being checked and logged. |

Object Tracking
being developed is computerized monitoring so
that a guard or operator does not have to endlessly
look at all the screens. This also means that
an operator can run many more video cameras. These
systems do not observe people directly. Instead
they track their behavior by looking for particular
types of movement, or particular types of clothing
or baggage. The computer can identify their movements
or behaviors, and alert the operator that they
are acting out of the ordinary. For example, they
can track movement across a scene where there
should be no movement, or they can lock onto a
single object in a busy environment and follow
it. Being computerized, this tracking process
can also work between cameras. |
