What is CCTV?

Closed Circuit Television (CCTV) is an installation of directly connected components creating a circuit which cannot be viewed by anybody outside of the circuit.

 

This is different to a terrestrial television broadcast system which anybody with an antenna and reception equipment can view.

 

Who needs a CCTV system?

IP Cameras systems can be found virtually everywhere in these days. They are no longer considered an expensive luxury item, especially when you consider your increased level of security.

 

Samsung CCTV systems can be found in both the private and commercial sector and are used for security/ crime prevention purposes and providing Health and Safety protection to the members of the general public.

 

You will have seen CCTV systems operating in town centers, high street shops, football stadiums, sports centers, on public transport, petrol stations  - the list is endless.

 

A CCTV system is a proven method of increasing the level of security of your premises. Its visual appearance alone will deter a criminal from approaching or entering your property for fear of being captured and identified on the system.

CCTV solutions can be tailor made to suit individual requirements. They can be as simple as one camera and a monitor, but it is quite common to have multiple cameras/monitors and recording devices in one installation.

 

The Elements of a CCTV System

There are three basic elements to a CCTV system namely the camera, lens and monitoring unit. The camera is the element which captures the image and transmits the picture back to a monitor. The camera needs a lens to be able to focus on the subject. There are a wide variety of lenses to suit different applications.

 

The monitor is the receiver unit which converts the captured image into a picture, allowing you to see it.

 

Color or Monochrome?

This is a very common question, but ultimately only you can decide.

 

A CCTV system should be designed to suit your needs, to fit into the environment on your property. The installing company should provide guidance on the suitability of different options, features and benefits - including colour and monochrome units. It may be that you need a camera that will work in colour during the day and automatically switch to monochrome at night!

 

Recording

 

As circumstances don't normally permit the luxury of having a dedicated person to sit and watch a monitor 24 hours a day, the image captured by the camera needs to be recorded so that it can be viewed later, if necessary.
