Fulmoni Behera, a student studying Political Science in a private university in Baripada, Orissa failed to figure out why the university authorities had suddenly become so keen on installing surveillance cameras in the campus. Since Fulmoni’s familiarity with cameras was limited to her father’s grand old Brownie Box camera which she had handled in her childhood days, she failed to fathom the utility of surveillance cameras, nor knew anything about their function and purpose. However, in her case, curiosity hadn’t killed the cat, while information about surveillance camera, also known as CCTV camera reached her via cousin brother Subhas, who reportedly was an expert in the working of surveillance cameras and the related systems.
Working of CCTV system, as explained by Subhas
A CCTV system, which stands for Closed Circuit Television system consist of four major components: camera, lens, monitor and video tape/recorder. Out of these, the camera is the most important item, since this is the one that catches the images. The CCTV camera incidentally functions the same way that an ordinary camera does, save and except that it can be left to operate on its own.
However, the basic difference between a still camera and a CCTV camera is that the latter comes with a motor that helps it to move the zoom parts. The moment an image is picked by the camera, it is relayed to the monitor (often through wireless transmission) and then automatically recorded on video tape or DVR . The ability of the camera to zoom in and zoom out is controlled by the type of lens it has been provided with. Since these systems are allowed to run 7 x 24 x 365, whatever happens before the camera/cameras get recorded automatically, one can view such incidents merely by checking ‘the footage’.
Why it is essential to install CCTV camera in educational institutes?
With ever increasing political influence on student communities all over the country, student unrest is a common feature in most educational institutes, often resulting in aggression and violence. What’s more, outsiders often take part in these issues. Even though the consequences could be felt by physical injury or death, the aggressor could not be identified and/or criminally charged with in the absence of truthful evidence. However, with the installation of CCTV cameras at strategic places, this task can be easily performed.
In a recent case where a student was murdered in the toilet of a school in New Delhi and the school bus driver was deemed by the police as the culprit, the accusation was diverted to a fellow student of the school who finally admitted to have committed the crime. This was possible through analysis of CCTV footage that recorded the incident. In the absence of such surveillance camera in the school, a wrong person would have been charged with murdering a boy and sentenced to life imprisonment or death by hanging.
Most educational institutes are currently provided with expensive tools and tackles such as computers, monitors, printers, microscopes, audio-visual equipment, etc that become targets of pilferage by deceitful persons. CCTV installed at strategic places could prevent/minimize such incidents, as also help identify the offenders.
Sexual assaults on girl students in schools, colleges and universities are now common occurrences everywhere. Installation of CCTV will go a long way towards preventing such incidents for fear of being trapped on part of the perpetrator.
Students like Fulmoni and others who seek more information about surveillance cameras and their use may find it most rewarding by visiting WeFe Technology P. Ltd in Bhubaneswar where the technicians attached to the Company that also serves as the premiere ISP in Orissa would be only too happy to explain the working of CCTV systems.
