Walk around any town or city, or even most supermarkets and shopping centres, and you will notice strategically-placed CCTV cameras beaming down at you. The primary objective of these is to monitor a certain area to watch for criminal activity and it can often be the case that a piece of CCTV footage proves vital in the prosecution of criminals. But how exactly is this technology used by police and investigators in attempting to catch the culprits?
This excellent infographic by JMC Technologies outlines the different types of surveillance that CCTV cameras cover – some capture a wide area, others hone in on specific detail – and it also explains the process of retrieving CCTV footage, plus the steps taken in disseminating the footage to other parties. There is also a list of guidelines that police and investigators should follow in using CCTV footage as evidence in a criminal case.
We’ve almost all seen these cameras gazing down at us as we go through our day-to-day lives, but had you really thought about how these are used in order to fulfill their ultimate goal of catching criminals cold?
