Title: Detailed Study of CCTV Cameras

Detailed Study of CCTV Cameras
  • 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,
  • 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
  • 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.

  • 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.
