Analysis of CCTV footage
All of us know CCTV is commonly used for a variety of purposes like maintaining perimeter security in medium- to high-secure areas and defense installations, observing behavior of incarcerated inmates and potentially dangerous patients in medical facilities, traffic monitoring etc. The amount of digital data generated by a single camera after compression is about 20 gigabytes per day. The number of camera increases with the increase of premises and its surroundings. If we are planning to store those data or video for longer duration (for example 6 months), the size of data would exceeds more than hundreds of petabytes which can be termed as Big Data. If any specific incident happens during that period, analysis of CCTV footage is only option to evaluate the actual truth. Hadoop is the only technology or paradigm who can address this effectively within a short span of time using commodity computers.
