Importance of CCTV

The full form of CCTV is Closed Circuit Television Cameras. These cameras can be fitted just about anywhere with the help of a simple process. Once set up, they help to record all the activities that are taking place in a specific area unless switched off or disabled. They are quite compact in size and are not really instantly visible to everyone. CCTV’s vary greatly in terms of the picture and sound quality that they can provide to their users. They may be colored or black and white. Some of them may show very clear pictures while others may showcase slightly hazy or disturbed videos. Thus, it is vital to choose carefully while buying CCTV cameras. CCTV cameras come with the following benefits and their importance cannot be undermined.

1.CCTV cameras are very useful in combating terrorism. This is because it is simply not practically possible to deploy police forces in every conceivable public area to look out for strange behavior from people or the placement of strange, unclaimed objects. CCTV cameras can look out for such things and prevent acts of terrorism before they have a chance to take place. The images captured on these cameras are transmitted to a central location where they are observed by the concerned person.

2.CCTV cameras are of unprecedented importance in the field of sporting. Some of them come equipped with high technology that helps to make crucial and difficult decisions in a game or match. Every single moment of play is recorded to be used later on too for making improvements.

3.CCTV cameras, if installed in a house or building, can help combat burglaries and thefts to a large extent. Just the knowledge about the existence of such cameras is enough to deter the possible intruders who may try to do away with your things at an available opportunity. CCTV’s can record footage and send it to another system over the internet. This can be done live or later on after the day has passed. So, it can help prevent burglaries and locate criminals whose faces may have been captured.

4.CCTV cameras are of great importance in places of work. They help establish a means of control and a system of keeping checks on the employees. If the employees are found to be wanting in a certain area, the requisite steps to correct this are taken by the management.

5.CCTV cameras in public places discourage vandalism and destruction of public property as the people involved in doing so know that they are being observed. Merely the existence of these cameras greatly improves the law and order situation of a city.

6.These cameras help keep a check on your babysitter’s method of working in case you have children and are worried about leaving them all alone with a stranger. You can be assured that your child is in safe hands and make changes if you find the nanny hired by you as incompetent in any way.

What is the difference between "biometric identification" and "biometric verification"?

What is the difference between "biometric identification" and "biometric verification"?

Biometrics are used for different purposes, but they are generally part of either a verification system or an identification system. The differences between these two types of systems can make a difference in how quickly the system operates and how accurate it is as the size of a biometric database increases.

Verification Systems
Verification systems seek to answer the question “Is this person who they say they are?” Under a verification system, an individual presents himself or herself as a specific person. The system checks his or her biometric against a biometric profile that already exists in the database linked to that person’s file in order to find a match.
Verification systems are generally described as a 1-to-1 matching system because the system tries to match the biometric presented by the individual against a specific biometric already on file.
Because verification systems only need to compare the presented biometric to a biometric reference stored in the system, they can generate results more quickly and are more accurate than identification systems, even when the size of the database increases.

Identification Systems
Identification systems are different from verification systems because an identification system seeks to identify an unknown person, or unknown biometric. The system tries to answer the questions “Who is this person?” or “Who generated this biometric?” and must check the biometric presented against all others already in the database. Identification systems are described as a 1-to-n matching system, where n is the total number of biometrics in the database. Forensic databases, where a government tries to identify a latent print or DNA discarded at a crime scene, often operate as identification systems.


one-to-one comparison, biometric verification systems are generally much faster than biometric identification systems. Most commercial applications of biometrics for time and attendance or access control use biometric verification.
