A closed-circuit television is a surveillance system that uses security cameras and that we can find more and more frequently, even in domestic environments.
Elements of a CCTV system
The simplest implementation of this type of system consists of a camera connected to a monitor or recording unit. From this starting point, the installation can be expanded by adding additional cameras. If desired, the installation can be supplemented with other elements such as motion sensors.
Surveillance is not the only use we can give to this type of installation. In summary, CCTV can be grouped into three main blocks:
- Video surveillance
In this way they can be used to identify individuals, monitor people or processes or identify all kinds of elements.
These uses imply their integration into passive security systems, both in companies and homes and even on public roads.
The advantages of having security cameras are very diverse, the most noteworthy being the following:
Deterrence of criminal activity
Security cameras have a great power of deterrence against all types of behaviors or activities that may constitute a crime. Here we can include from theft to assaults or reckless driving.
Reduces the cost of insurance policies.
Closely linked to the previous one, if we have a closed-circuit television in our business or home, the risks of burglary decrease and the cost of insurance is usually lower.
In addition, the images taken can serve as evidence in the event of any incident.
Sense of tranquility
Many times it is not enough to be protected, it is necessary to feel protected. Having a camera system gives us extra peace of mind because we have the confidence that our property is being watched.
Disadvantages of video cameras
Like any other security system, this type of installation has its drawbacks.
They do not stop the thief
Despite being key in any process of identifying thieves or aggressors, they cannot prevent the crime from being committed and, by themselves, they are not capable of alerting neighbors or the police.
In some cases, these systems may jeopardize people’s right to privacy.
In workplaces, the installation of these cameras may not be welcome as it generates distrust and tensions in employer-employee relations.
