CCTV

What is CCTV

CCTV stands for Closed Circuit Television, and is a system of security cameras all linked to one monitoring system. It is different from broadcast television in that the signal is not openly transmitted. Though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that may need monitoring.

CCTV Brief History:

The history of CCTV in the United States varies from that of the United Kingdom. One of its first appearances was in 1973 in Times Square in New York City. The NYPD installed it in order to deter crime that was occurring. During the 1980s video surveillance began to spread across the country specifically targeting public areas. Some businesses as well, especially those that were prone to theft, began to use video surveillance.

CCTV later became very common in banks and stores to discourage theft, by recording evidence of criminal activity. Their use further popularized the concept.

In recent decades, especially with general crime fears growing in the 1990s and 2000s, public space use of surveillance cameras has taken off.

What are some types of CCTV Systems?

CCTV are divided into two types

  • 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.

CCTV Components

CCTV systems are composed of a variety of components for viewing, recording, and archiving video footage that offer a wide range of surveillance benefits.

  • Cameras
  • Digital Video Recorders (DVRs)
  • Coaxial Cable
  • Monitors

Where is a CCTV Camera?

A security camera is used in surveillance to monitor public or private areas that need to be monitored for security reasons. Modern security cameras used closed-circuit television (CCTV) technology, which employs video cameras that transmit signals to a specific set of monitors.

How do CCTV Cameras Work?

CCTV camera systems includes one or more cameras which are used to send video images and audio data to a monitor. Basically, these camera systems use cameras to transmit the signals to a main digital recording system or hub which then records that date for a later viewing or live remote viewing.

What are types of CCTV Security Cameras?

  • Bullet Camera: Bullet Cameras are placed inside Bullet shaped housing, and they are used in residential places as well as commercial places. they are small in size, have an integrated design and water-proof also.

  • Vandal Proof Camera: Vandal Proof cameras are used as outdoor security cameras. These cameras are sheltered within solid material and covered by a “hub” of break-proof glass which doesn’t affect the quality of the video. It is difficult to break these cameras and this makes them perfect for high security.

  • Hidden Camera: Hidden cameras are compact in size and are used for secret monitoring. They are usually installed in public places like department stores, theatres, clubs, etc. Hidden cameras have a built-in recorder that records and broadcasts simultaneously.

  • Pan Tilt Zoom Camera: Pan-tilt-zoom camera offers the ability to view and zoom in all directions. We can even set the camera to automatically rotate to different fields of vision.
