What is CCTV ?

hi

CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes.

CCTV relies on strategic placement of cameras, and observation of the camera's input on monitors somewhere.

Because the cameras communicate with monitors and/or video recorders across private coaxial cable runs or wireless communication links, they gain the designation "closed-circuit" to indicate that access to their content is limited by design only to those able to see it.

Older CCTV systems used small, low-resolution black and white monitors with no interactive capabilities.

Modern CCTV displays can be color, high-resolution displays and can include the ability to zoom in on an image or track something (or someone) among their features. Talk CCTV allows an overseer to speak to people within range of the camera's associated speakers.

Maintaining perimeter security in medium- to high-secure areas and installations.

CCTV is commonly used for a variety of purposes, including:

Maintaining perimeter security in medium- to high-secure areas and installations.
Observing behavior of incarcerated inmates and potentially dangerous patients in medical facilities.
Traffic monitoring.
Overseeing locations that would be hazardous to a human, for example, highly radioactive or toxic industrial environments.

CCTV is finding increasing use in law-enforcement, for everything from traffic observation (and automated ticketing) to observation of high-crime areas or neighborhoods. Such use of CCTV technology has fueled privacy concerns in many parts of the world, particularly in those areas in the UK and Europe where it has become a routine part of police procedure.

The term closed-circuit television (CCTV) describes video surveillance that is not openly transmitted, otherwise known as surveillance systems used for security purposes in airports, stores, banks, hotels, hospitals military installations and elsewhere. Early CCTV systems required continuous human monitoring.

Later, CCTV evolved to include motion detection – which required less monitoring – and recording capability, which began in the form of analog tape before transitioning to digital storage. More recently, CCTV systems have evolved to include face recognition technology, and is often referred to as biometric surveillance.

Modern technology helps to secure places with the use of access control and modern security cameras. Perhaps you already saw the term "CCTV" while researching around but you really don't know what it means.

CCTV stands for Closed-Circuit Television. It's a video surveillance system used for security purposes. The first CCTV system with analog cameras was used in 1942 in Germany to monitor rocket launch and later evolved to a more sophisticated system that uses digital surveillance cameras with video analytics capabilities.

What many people don’t know, however, is that there are a variety of different types of CCTV camera which suit different situations or premises, and that selecting the proper camera for the right application really is vital.

CCTV plays a huge part in today’s society, and with cameras all around us, our day-to-day lives are experiencing higher levels of security each day.

CCTV is a technology widely used around the world for decades. There are many modern CCTV cameras that can be used for different applications, even for monitoring your home.

The cameras are installed on different places to monitor people, cars and everything else that can compromise the security of the area.

What many people don’t know, however, is that there are a variety of different types of CCTV camera which suit different situations or premises, and that selecting the proper camera for the right application really is vital. Here, we run through these types of camera and what makes them unique and more suitable for some venues over others.

In this article, you will learn about analog and digital CCTV systems and what the key features and advantages of each of them are.
