1
What are the Types and Function of the CCTV
Devices?
2
  • CCTV is the short form of Closed Circuit
    Television. It is a system that includes cameras
    and used as the key device to monitor the people
    present in some events or a public area. The main
    places where these cameras are used is the
    government offices, banks, shopping malls,
    terminals and subways and sometimes in the
    houses.

  • It is mainly placed in the public areas for
    proper safety and surveillance of the citizens.
    The CCTV devices contain equipment such as a
    lens, cameras, cable wires, controllers, and
    monitors. There are several types of CCTV
    gadgets, such as the digital system, analog
    system, wireless system and wired connection
    facility.

The Difference Between the Unit Types

  • The analog security system is the basic type
    of other units. It is very easy to install this
    device. It is installed with a camera which
    captures the moment, a VCR to record the event
    and a television for monitoring the people. An
    analog system comes with a most reasonable price,
    compared to other devices. It has the basic
    system that has the ability to capture specific
    events. Another form of a dependable security
    procedure is the digital system.

  • A digital system unit works with a
    stand-alone hard drive or a computer hard drive
    and stores the data that it captures. This gadget
    is made in such a way that it has the ability to
    convert the signals of video to digital signals
    so that the hard drives will have more space to
    save the information. If we compare it with the
    analog devices, youll see that it has more
    capacity to store information. This kind of
    security facility is famous all around the world
    and used by almost all public places including
    the streets and road.

  • So, if you wish to install these devices in a
    place to check on the daily activity of the
    outsiders, install these devices with an expert
    professional help. The type of wired connection
    system is the third form of CCTV footage system.
    A wired CCTV connection includes a recorder, a
    monitor, a coaxial cable and mainly the camera.
    The coaxial cable has the ability to ignore the
    interruptions in the signals caused by the
    adverse climatic situation such as heavy rains
    and other sources.
