CCTV SYSTEM

• There is a phrase commonly used among internet
  users i.e. Nothing is Safe. Adhering to this
  phrase industries have been trying from years to
  come up with security systems that are completely
  safe. But this task has been almost impossible as
  always there is some or the other bugs found.
  Nevertheless there are certain products which
  have been very efficient in their working such as
  CCTV Cameras, spy pens, etc. The main focus here
  is over CCTV Cameras, its usage and future
  advancement in the latter.

How Do CCTV Cameras Work?

• CCTV camera systems has one or more cameras which
  are used to send video, images and audio data to
  a monitor. Essentially, these camera systems use
  cameras to transmit the signals to a main hub
  which then records that data for later viewing or
  live viewing if you have full time security
  personnel on your premises.

Types Of CCTV Cameras

• CCTV cameras are being installed every where for
  purpose of security and crime prevention and
  detection. There are many types if CCTV cameras
  are available for this purpose. These are

• Indoor Camera
• Outdoor Camera
• IR Day/Night Camera
• Dome Camera
• Bullet Camera
• Vandal Proof Camera
• Hidden Camera
• Pan Tilt Zoom Camera

Types Of CCTV Systems

• CCTV Systems are broadly divided into two types.
  These are
• Wired CCTV System Wired CCTV systems connect
  the camera to the recording device and monitor
  with the help of standard coaxial cables or
  Unshielded Twisted Pair(UTP) cables or fiber
  optic cables. The image data is usually
  transmitted over a coaxial cable. The signal
  transmitted over these cables is then fed into a
  monitor or set of monitors if the image needs to
  be visible indifferent locations.
• Wireless CCTV System Basically, Wireless CCTV
  systems are similar to wired CCTV systems. The
  difference is that a radio transmitter is
  attached to the camera. A radio receiver then
  attached to the input on the monitor system or
  computer. Wireless systems are useful when the
  distance between the camera and the monitor is
  too far to be practical for a cable run.

Applications Of CCTV

• CCTV is commonly used for a variety of purposes,
  including
• Maintaining perimeter security
• Observing behavior potentially dangerous
  patients in medical facilities.
• Traffic Monitoring
• Building and ground security.
• Overseeing locations that would be hazardous to
  a human. for example, highly radioactive
  environment.
• Obtaining a visual record of activities where
  it is necessary to maintain proper security. for
  example, in banks, casinos, or airports.

The Future Of CCTV Cameras

• The future of CCTV is IP CCTV. IP CCTV stands
  for Internet Protocol Close Circuit Television.
  With IP CCTV the video management has become so
  simple. You can store and retrieve both analog
  and digitally recorded video footage and access
  it via an internet connection anywhere in the
  world. Especially with the growth of Cloud
  Computing, the IP CCTV has seen a massive boom.

Conclusion

• When used in moderation, under the correct
  guidance, Surveillance cameras can be invaluable
  in aiding the police in their investigations.
  CCTV can also act as a twenty-four hour police
  presence, helping to make the public feel safer.
  If used excessively however, the massive increase
  in the number of CCTV cameras can lead to an
  invasion of privacy and violation of human
  rights. The cost of the cameras has also been an
  issue that has caused many debates as to whether
  the cost is worth the results. There needs to be
  reform into how the authorities use the existing
  surveillance cameras to enhance their
  effectiveness to their impact on crime.
