Number of CCTV Cameras in XLRI
Case Statement:
Guess the number of CCTV cameras that are installed in the campus of XLRI.
I: Let’s consider all CCTVs cameras in the XLRI Jamshedpur campus.
C: I would like to segment the usage of cameras into indoor and outdoor. Indoor would include all buildings that have cameras and outdoors would include the roads, eateries, courts etc.
I: How would you like to segment the indoor usage of cameras?
C: I would like to segment the indoor buildings based on the primary users. People residing on campus can be segmented into three groups – students, faculty & admin. The students primarily use hostels, learning centers, library and the auditorium. The faculty use their offices and their residences. The administration uses their offices.
I: That seems like a fair approach. What kind of numbers are we looking at?
C: I would like to estimate the number with the following data and assumptions. We would thus have around 464 CCTV cameras in the Jamshedpur campus.
Background Information
Area of XLRI : 2,00,000 m2
Area covered/camera: 150 m2
Case Tips
Clearly drawing the structure and mentioning the segmentations makes it easy to visualize.
This approach can be extrapolated to malls/other campuses/townships etc.
