CCTV: What Is This?

CCTV build

Closed Circuit Television System. It is designed for visual monitoring and control of video image or its automatic analysis (including recognition of state numbers of vehicles and persons) using optical electronic devices and components.

CCTV – what is this system, which includes video cameras, hardware, monitors, recorders, lenses, as well as various elements for signal amplification. The main task of this system is to carry out surveillance on local, local, remote objects. The majority of trading platforms, warehouses and enterprises are equipped with a similar video surveillance system, which allows to observe the actions of employees and visitors, monitor the activities of personnel and generally ensure the normal operation of the enterprise and protection from crime. These are the main functions of the system.

Destination of the CCTV video surveillance system With this system you can:

  • To control the situation at a certain object.
  • Receive information right at your post in real time.
  • Ensure that video and audio are captured using a digital recorder.
  • Get video confirmation of the violation at the object.
  • Implement the alarm function, which will be based on the work of camera motion detectors or sensors.

Perhaps now you understand that this is a CCTV. The system can be considered in more detail.

CCTV cameras

The most popular security cameras on the market are models based on CCD sensors. The largest manufacturers of such cameras are well-known brands: Samsung, LG, Panasonic, Sony. Moreover, they offer both cheap economy class cameras and expensive high-quality equipment with wide functionality and increased reliability.

According to the design characteristics of CCTV cameras can be divided into several types:

  • Modular. These are housingless devices that are installed in hemispheres or housings. They are so called because they do not have their own enclosure.
  • They are miniature. These cameras in small housings are usually square or cylindrical in shape, used for indoor video surveillance, but it is very rare to find models with protective housings for outdoor use.
  • Dome housings. They are used indoors and are usually attached to the ceiling or other horizontal surfaces using a special bracket.
  • Housed. These cameras are designed for video surveillance in all conditions and rooms. They can be used outside or in buildings regardless of their accessories. Note that if they are used outdoors, they must have special thermal housings that protect the devices from frost and water and dust ingress. All this can damage electronic components, so the housings are mandatory. Otherwise, even the enclosure chamber will not last long.
  • Outdoor cameras. If any camera is installed in a thermal cover with a heated lens, it already belongs to this class. It is easy to guess that they are designed for outdoor surveillance.
  • Rotary and speedy. This class includes cameras with a swivel mechanism and zoom lens. It should be noted that the potential of these cameras is greater in comparison with others, so they are often used to implement effective CCTV systems.
  • Hydrostabilized video cameras. These have special video stabilization systems, so they can be used on mobile objects.

In addition, for the organization CCTV system can be used analog or digital (known as IP-camera) models. Similar division can be carried out, considering designs of the device itself. For example, cameras can be wired or wireless. The latter have a high frequency antenna as a transmitting device. It can also be a Wi-Fi interface.

Recording Devices In order to finally understand what CCTV is, you need to consider video recording devices as basic elements of the system along with cameras. These are digital video recorders that record video and audio to a hard drive or other storage device.

They all fall into three categories:

Video servers – devices that are organized on a simple computer running Linux or Windows operating system with the use of video capture card and software for processing and recording video. If we are talking about organizing security of a very large enterprise, for this purpose, specially assembled computer, which later becomes the core of the security system.

Non-computer registrars like non-PC, DVR, Stand-alone.

Specialized registrars. These are systems which may include different components designed to solve specific tasks. For example, there are recorders designed to record and store video received from CCTV cameras in subway cars. In this case, explosion-proof memory can be used.

Image processing devices

No CCTV system can be implemented without this element. The image from the camera must be transferred to one monitor. For this purpose, switchers or video switches are most often used. When it is necessary to transfer several images from different cameras to one monitor, a square is used.

A more complex device is a multiplexer. It allows to organize simultaneous display of images received from different cameras and broadcast on the monitor screen. Also with its help it is possible to form consecutive change of images from all cameras for recording purposes.

Types of lenses

We have already figured out in detail what it is – CCTV. But it is possible to put a final point after consideration of kinds of lenses. At the organisation of this system the following lenses can be used:

  1. Monofocal lenses with constant focal length which does not vary.
  2. Variofocal lenses in which the focal length can be manually adjusted.
  3. Transfocators. Here the focal length can be changed manually or automatically. Changing this setting allows you to zoom in or out of the image, which to some extent provides increased reliability.


Now you know that this is a CCTV, what is the purpose of this system and the basic elements that make it up. If earlier this system was a rarity, today it is implemented even in the largest retail outlets. It is a rather flexible system which can cost millions of rubles or only 5-10 thousand, but its main task is to organize video surveillance of an object. Taking into account the flexibility and variety of its components, there is no specific CCTV instruction, because for each object it will be individual, taking into account the cameras used, image processing and recording devices.

Physical and technical security of the casino

Seciruty CCV

Casino of any level is always a combination of large cash flow and people. In the gaming business, success largely depends on a properly constructed security concept.

In essence, the security of casinos – a broad security structure, which includes units of different specializations.

Casino’s risks are high:

  • thefts
  • customer fraud
  • vandalism
  • staff fraud
  • conflict and disorderliness
  • robberies

All this brings tangible losses to the institution, its image and jeopardizes the profitability of the entire casino business. To prevent this, reduce the risks and damage can only a professional security agency, which has many years of experience in providing services in this area of business and the appropriate professional staff.

Technical security equipment

The casino is offered to be equipped with security systems:

  • intrusion protection
  • fire alarms
  • game-monitoring system
  • parking system
  • access control system

Security and fire alarm system

All rooms of the casino are equipped with a fire alarm system, the draft of which is approved by the state supervisory authorities.

The security alarm system may be equipped with the premises of the institution, safes, vaults, cashiers, etc. It is also possible to install remote buttons of the alarm system (KTS). In case of emergency, security officers can call the State Guard Service detention group, which arrives at the facility within 2-4 minutes.

CCTV system

Perimeter, parking lots, indoor casinos are equipped with video surveillance cameras. The gaming room is equipped with high-resolution video cameras, which allow us to clearly transmit colors (cards, roulette, etc.), as well as get a clear image, which is necessary to control the game processes.

In addition, to stationery, fixed video cameras provide for the installation of robotic, controlled, with which to quickly monitor the entire gaming room of the casino. The characteristics of this equipment allow you to quickly focus the camera on the desired object and if necessary to consider an object of 1X1mm.

The design of the operational surveillance center of the casino. This is a closed operating room, which brings together all the security systems and communications of the institution. A special place is occupied by racks monitoring and management of video surveillance systems. Video systems should be designed in such a way that the operator could with minimum time and effort to obtain video information of the required quality from anywhere in the casino gaming room.

Parking system

The parking system is a part of the casino access control system and consists of automatic barriers, control controllers and readers (if necessary, the system can be complemented by parking payment terminals). The key identifier is a contactless card. Such cards can be issued to regular casino clients or as one-time cards – for one visit.

With the help of the card, the driver of the car can pass to the parking area bringing it to the system reader without leaving the car. In this case, the access control system is recorded information: date, car number, photo, information about the client.

Access control system

The door leaves of входов\выходов are equipped with electromechanical locks in the casino’s service rooms, and full profile turnstiles or airlock cabins can be installed at the entrances of safe rooms or vaults. The equipment is connected to central access control and management system, which performs functions:

  • authorized access by casino staff to their workplaces
  • Recording and accumulating data on staff movements within the institution, indicating their exact location
  • timekeeping and reporting
  • remote control (блокировка\разблокировка) of all turnstiles and locks
  • fleet management

Physical Security

The main task of protecting the casino is to ensure the safety of life, the health of employees and customers, the integrity of the institution, the safety of material values and the financial assets of the casino.

The main emphasis is on the knowledge and control of casino life, orders, principles, and mechanisms of the game processes.

Security groups are divided by :
casino guards

  • casino security
  • security inside the gaming room (knowledge and control of game processes)
  • emergency response teams
  • operational surveillance center (control and coordination of all groups and technical means of security, monitoring of the object as a whole, video control of game processes)
  • cash collection, escort, and control
  • VIP – security, support of wealthy casino clients

For the normal functioning of any casino, an important condition is to ensure complete safety for its visitors. Before opening it will be necessary not only to choose reliable security guards, but also to equip the room with modern technical devices designed to ensure security (motion detectors, alarm sensors, video surveillance systems, etc.).

The entrance to the casino is equipped with metal detectors. Since only the casino gaming room is not limited, it is desirable to equip as many of the available rooms as possible with telephones and alarm buttons connected to the central security console. It is necessary to maximize automation of the entire security system, so you can avoid many unpleasant moments in the future work.

Video surveillance systems will allow you to monitor the situation at any point of the casino. Despite the fact that the video cameras are a security device, it is guarding their purpose in the casino is secondary. After reading the unique review, we can conclude that the honesty of the casino is extremely important for visitors. Therefore, video surveillance systems in gaming rooms should solve problems more complex than usual. They are required to constantly monitor the game in the room, so that with the help of the record can expose the possible dishonesty of all the people near the gaming table, that is, both visitors and staff. Sometimes it also happens that even honest players make mistakes for some reason. For example, they can claim their winnings, in fact, just by mixing up something. In such cases, the loyalty and trust of the client can be maintained by allowing him to verify the integrity of the casino by recording everything that happens.

In all casinos without exception, attempts at deception may be made. Sometimes fraudsters manage to get such amounts, which are many times higher than the possible cost of any security system. It is extremely important to take seriously the choice and installation of security equipment and to select qualified personnel.

It is recommended to install at least two cameras above each table, and fixed cameras are more preferable in this case, as only they can get a clear and continuous record of what is happening on a particular table. Rotary cameras have a greater overview function and require constant attention from the operator.
