What are CCTV systems?

The very name CCTV comes from English and is an abbreviation for "Closed Circuit TeleVision". In free translation into Polish, this means closed-circuit television, but it has become accepted to be called CCTV. What exactly does a CCTV system consist of and how is it used?

Basic features of functioning of CCTV systems

To put it simply, CCTV systems are teams/systems of cooperating devices whose purpose is to monitor and record images from cameras (sometimes also sound). It is then processed and transmitted to a designated system of monitors or video recorders in a limited area. The transmitted video and audio is then archived and can be played back at any time in the reception centre.

This is one of the best ways to increase safety in your area. It may concern both the monitoring and protection of a detached house and its property, as well as the entire building complex. It works very well, for example, in public places where large groups of people constantly move, such as shopping centres, schools, banks, factories and production halls, and even airports.

What are the individual components of a CCTV system?

The CCTV system consists of

  • monitors and video cables,
  • CCTV cameras and lenses,
  • recording equipment,
  • Wireless cables or kits for audio and video transmission,
  • power supplies and power cables,
  • housings, handles and other accessories,
  • motion detectors..,
  • Optional routers for Internet connection,
  • network cards and micro servers.


Purpose of a CCTV system

As mentioned before, the main task and purpose of CCTV systems is to increase security in the area they monitor. From small households to whole cities. The recognition of someone's face when a crime is committed becomes possible in a very short time. In public places where the flow of people is difficult to control, advanced monitoring makes it very easy to act effectively if needed.

With more people involved in an incident or incident, the CCTV system helps to track the route taken by the suspect(s). It also makes it easier to predict future objectives. When this type of monitoring is in use, it is much easier to inform the relevant services in order to react quickly e.g. in case of breaking the law or an accident. Besides all this, it can also act as a deterrent, as many people will not commit a crime knowing that everything will be recorded with cameras.

Various CCTV systems

The categories of CCTV are divided into, among others:
- analog monitoring - sends data in the analog domain,
- HD-CVI monitoring - enables transmission of high resolution (megapixel) signals in analog domain,
- IP monitoring - uses Internet protocol for data transmission.

What to remember when choosing a CCTV system?

The key to success, i.e. maximising the level of safety, is the following. From the very beginning, it is necessary to design CCTV network in an appropriate way. Make sure the eye of the camera reaches in sensitive areas. For this you will need appropriate equipment, i.e. industrial cameras, adapted to the conditions in which they will be installed. Then you should pay attention to the installation process itself and, above all, the system configuration. Once this task is completed, you can proceed to a test run of the system. If everything works well, all that remains is to remember about regular maintenance during use.
