cctv surveillance for system security

CCTV Cameras, The Best Solution for Surveillance!

This is exactly the thing you need for your company, home and stores. We offer quality and long lasting products for complete surveillance with free installation by technicians.

CCTV (Closed Circuit TV) uses one or more video cameras to transmit video and sometimes audio images to a monitor, set of monitors, or video recorder. The difference between CCTV and standard TV is that standard TV openly broadcasts signals to the public. CCTV is not openly transmitted to the public. CCTV uses either wireless or wired transmission to send the broadcast from the video cameras to the monitor(s) or recording device. Most CCTV systems are used for surveillance, which can include security monitoring, spying, or safety monitoring

Security Camera

Security camera captures the video of the source. An opened aperture at the front of the camera captures light stream through the camera lens. The light stream is captured by a digital chip that is fitted inside the camera and is converted into the continuous stream of images. The camera records the signal to be transmitted either through cables or wirelessly. The distance between the camera and the object is determined by the camera lens specifications.

Infrared Light Emitting Diodes (IR LEDs) are used as sensing devices in CCTV cameras. The light sensor is used to detect the ambient light level i.e. it detects the brightness of light it receives and transforms it into a numeric value that tells the percentage of brightness.

Due to the digital technology employed in data recording and processing, it is possible to receive sharp images, clear audio and fewer signal interferences from the wireless cameras. This type of camera is often referred as “IP Camera” (we will talk in more details later)

Typical uses of CCTV cameras

Crime detection or prevention

The chief use of CCTV cameras is for surveying an area with the aim of detecting and preventing crime. Most car parks, supermarkets, major stores and other public places fit surveillance cameras for this reason.

Industrial use

Monitoring of critical industrial processes mainly employs CCTV cameras and not human beings. This is very true in the case of chemical based or nuclear-based industries. For example, thermo-graphic CCTV cameras find unique application in nuclear fuel plant.

Traffic use

The main cities do experience huge traffic congestion or accidents. Closed circuit cameras can then be fitted along the streets so as to automatically record any accident or indicate the roads with more traffic jam.

Used in schools

In many developed countries, CCTV camera system is used to keep a check on students who are prone to vandalizing school properties or those who find pleasure in bullying their colleagues.

Transport industry

Surveillance cameras are also used in the transportation services. For example in an underground train, through the utilization of a surveillance camera, an operator can trace the passengers’ movements so as to know when to open or close the doors.

Monitoring employees

Major organizations and companies use CCTV cameras to keep track of employees in different sections. The cameras would send video signals for each process. Through that, it is possible to pinpoint for a delayed stage of production.

CCTV cameras are sometimes prone to vandalism hence rendering them ineffective. To overcome this problem, manufacturers, have come up with cameras which are resistive to different things like:

  • An explosion proof casing
  • Dust resistive housings
  • Bullet resistive casings
