What is a CCTV system?
Closed circuit television is a technology based on the monitoring of environments through analog or digital cameras that has been widely used in recent years in homes, companies, commercial establishments and condominiums. This involves placing cameras at strategic points in the environment to be monitored. The captured images are transmitted to one or more viewing points, contributing to the reduction of crimes in these places.
Closed circuit television functions
- Prevention and repression of crimes, inhibiting the action of offenders
- Identification of offenders, being an ally in the fight against crime
- Increased sense of security in the environments in which they are installed
How the CCTV System Works
Security cameras send the video signal or captured images to the capture card, where the information is recorded and stored. For the camera to work in perfect harmony with the capture card, it is necessary to install a converter to match the impedance between the equipment. In this way, the camera is also free from interference with the video signal.
For the proper functioning of a security camera system, it is also necessary to install a power supply of good quality and adequate dimensioning for the cameras. It is also necessary to have quality in the connector and video cable to not have loss in the signal. In addition, there must be a power supply on the break.
To start evaluating the quality of a security camera, we have to take into account a few factors:
- Resolution in number of lines: The resolution of the camera is based on the number of lines, that is, the greater the number of lines the better the quality of the security camera will be
- Image Sensor: The image sensor is responsible for image sensitivity, sharpness, color and brightness
- Lens Quality: The Lens needs to be of good quality, because without it the image sensor and the resolution usually do not work properly, leaving the image bad.
The installation of the CCTV system is done by studying the environment with the choice of the points where the cameras will be placed. This mapping is important because it identifies the vulnerable points in the environment. The next step is to choose the equipment, and that is where it is necessary to hire a specialist in the subject, capable of setting up an efficient and safe system that meets your expectations and meets the needs of each type of environment.
Now that you know a little more about the security camera systems in Chicago, you can see how the use of electronic monitoring is relevant when it comes to security and peace of mind.
