The term CCTV, also known as Closed-Circuit Television, refers to a technology that, through the interconnection of various devices, allows for the capture, display, and video recording of different situations that occur in a specific location. This system, whose main objective is to reduce the risks associated with security issues, is essential in the management and supervision of a wide variety of spaces.
In addition to security, CCTV systems are also used in several other applications. For example, they can be employed to monitor and supervise industrial and logistical processes, manage traffic, and in the fields of healthcare and commerce. They also have educational applications, opening up new avenues for learning and collaboration.
The aspect that sets CCTV apart from regular television broadcasts is that, while the latter can be tuned in by anyone with a receiving device, CCTV signals are restricted to a specific audience and can be configured according to the project’s needs and user requirements.
In general terms, the applications of CCTV can be divided into two main categories: monitoring and verification.
In the case of monitoring, the CCTV system is used to establish a control center that is monitored in real-time. An example of this would be a shopping mall or a casino, where security personnel use CCTV images to alert about unusual situations and maintain the security of the place.
As for verification, CCTV systems are used to confirm events that have already taken place. This can include extraordinary situations that require post-incident review, whether to implement corrective measures, identify process flaws, or take actions to reduce the risk of a similar incident happening again.
In terms of utility, CCTV systems have a wide range of applications in different sectors. They can be used in residential contexts as well as in large-scale community surveillance projects. In the medical field, for example, CCTV systems are used in intensive care units, psychiatric centers, and remotely-assisted surgeries. In industry, they are employed to monitor production lines and variables such as pressure, temperature, and flow, providing invaluable information to process control engineers. Finally, in the educational field, CCTV allows for the creation of simulation centers and real-time transmission of classes to various groups of students.
