It is pivotal to consider security important these days. It is not simply large scale organizations and business properties that need great security but small scale stores and offices as well. With crime increasing and thefts becoming frequent, it is essential to consider the accessible security alternatives and pick one that is the best fit for you and there no other option is better than CCTV Surveillance.

Common usage of CCTV:

• Maintaining perimeter security in medium- to high-secure areas and installations.
• Observing behaviour 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.
• Building and grounds security.
• Obtaining a visual record of activities in situations where it is necessary to maintain proper security or access controls (for example, in a diamond cutting or sorting operation; in banks, casinos, or airports).

Impact of CCTV on Smart Cities of India

No modern society in the world today operates without some level of it, and no modern society is free of the debates that surround it. Few can deny that CCTV cameras play a significant role in crime prevention and detection, and in maintaining law and order. Yet, the same people are likely to rail against the loss of privacy and unwanted invasion into our personal lives that comes with our movements being monitored every hour of every day.

In various cities of India, it is mandatory to install CCTV cameras in many commercial establishments, such as banks, ATMs, pubs, restaurants and cyber cafes. In addition, the kind of public places that have been coming under the ambit of cameras has been going up every month: it is now compulsory for public buses, schools, school buses, residential apartments with over 100 residents, hotels, jewellery stores, and places of worship to have CCTV cameras installed. In addition to this, most traffic signals in metro cities are now monitored by network surveillance, as are major bus-terminals and railway stations.

Do CCTV Cameras Make Cities Really Safe?

Safety and security have never been discussed in India as they are now. Threats are from everywhere, and at all places. Security checking at offices and shopping mall entrances has become a ritual.

CCTV systems have an objective of reducing crimes. However, same key questions remain unanswered – like do CCTVs really prevent crimes from happening? Or do they merely help catching a criminal once the crime has happened? How many of them really work and how strong a mechanism they are in ensuring public safety. Manual inspection of video cameras – one frame (per second ) of CCTV can generate up to dozens of meaningful events of interest .This means that a security person watching a CCTV has a potential of tens of thousands of events to observe in an hour. This is huge volume for any human eye and mind. A typical human mind can pay attention for only few hours and few thousand events which make it practically impossible to catch all the events that CCTV footage is capturing by manual inspection of CCTV cameras. However, this does not imply that manual inspection of CCTV is not valuable. CCTV and manual inspection of CCTV plays a huge role in providing safety to an extent human eye and human mind can pay attention. However, human factor (mind and eye) also comes with a limitation in manual inspection and hence the effectiveness of CCTV cameras at times is adversely impacted.
