CCTV, an acronym used for Closed Circuit TV, is a technology based on monitoring environments through analog or digital cameras, and can be used in homes, commercial establishments, rural areas and condominiums.
CCTV (Closed Circuit Television), it ensures internal monitoring, carried out through security cameras distributed in a certain area and connected to a central system. In it, the images are recorded and made available on monitors.
Usually used for monitoring and CCTV installation in Chicago, CCTV aims to capture and record security incidents, as well as cases of vandalism, improper behavior, and robberies, among others.
Thus, the security team is able to monitor, in real time and remotely, what is happening in each environment, 24 hours a day, seven days a week. This, consequently, allows actions to be taken in cases of need.
In addition, the presence of a CCTV system acts to inhibit criminal actions, since it makes it clear that all movements carried out in the area are monitored and recorded.
How does the CCTV installation work?
With an increasing adhesion of customers, CCTV demands a study of environments, so that it is possible to choose the points where the cameras will be installed. The mapping, carried out by a qualified professional, is extremely important, since it identifies the vulnerable spaces in the environment.
Subsequently, the model (DVR / NVR / HVR) is defined, which will be responsible for managing the cameras. This, of course, also takes into account how many and what equipment will be needed in each situation.
It is also important to define where the DVR will be installed. The space must be safe, to prevent the equipment from being damaged or stolen.
In addition, the camera models chosen must meet the needs of each environment. An outdoor environment, for example, needs equipment with protection from rain and vandalism.
Then, the appropriate cabling is defined, whether coaxial or UTP, and the power points that will be used.
The management and storage equipment has the function of centralizing the images collected by the different cameras. From this, they make these images available on monitors and other access devices. They can also record the scenes stored for possible future reference.
In analog systems, DVR (Digital Video Recorder), which only works with images generated and sent by analog cameras. The NVR (Network Video Recorder), in turn, is used by digital systems, with images via IP. HVRs (Hybrid Video Recorders) are able to work in a hybrid way with both types of equipment.
What are the benefits?
The use of CCTV allows the security team to monitor, 24 hours a day and in real time, what happens in each of the filmed environments. In this way, it is possible to take the necessary actions when detecting any abnormality.
In addition, it facilitates the administration of environments, even remotely, allowing managers to have greater control, even when working from home or traveling. And all this with easy and fast access, since the videos can be accessed live and on any device, whether notebook, cell phone or tablet, as long as you have access to the Internet.
In addition, it allows recorded images to be recorded for possible subsequent analysis, which helps to identify suspects. In specific cases, they can be used as evidence in legal proceedings.
