Safety

at all times has been one of the main components of almost any aspect of human activity. Security system connection is a guarantee of confident, quiet and controlled protection of the protected object, regardless of whether it is a large enterprise or a small office. The structure of any security system includes a number of basic elements, including video surveillance systems.

The main task of the CCTV system is the continuous monitoring of the protected area. At this stage of the development of video surveillance systems, the system, correctly designed and worked through all nuances, allows you to move away from constant visual control by the operator. The system itself attracts the attention of the operator with audio signals and graphic "hints" on the image, thereby reducing the importance of the human factor (for example, when the operator is distracted by a phone call and may not notice illegal violations of the protected object / territory). In addition, in modern video surveillance systems it is possible to realize many auxiliary functions, such as: recognition of license plates of cars, control over left objects, counting the number of people caught in the field of view of the video camera for the necessary period of time, searching objects in video recordings in form and color, recognition Persons. The CCTV system will help prevent illegal penetration, will allow to receive an alarm signal in time to the security room and, if necessary, to recognize the car number. At present, ordering video surveillance means to receive reliable and comprehensive protection. Nevertheless, all equipment that includes video surveillance must be installed and connected only by qualified specialists. It is this factor that guarantees that security will really be at the highest level.

To install a CCTV and CCTV system, you must choose the company that provides a full range of related services. They usually include design work, the use of quality equipment and its installation, as well as the introduction of the system into operation.

Today, video surveillance systems are very popular, they operate on the basis of IP cameras. Modern technologies of IP security systems successfully supersede analog systems from the market due to wider functionality, greater flexibility, better operability, better image quality. Here is a simple example: for an analog system, installation of coaxial cables and power cables from scratch is required, which means longer lead times, large amounts of materials, etc., and if the work is carried out in an already used building, this entails certain Complexities, such as, for example, laying cable routes through working offices and offices, which can not be said about IP-systems. The IP-Surveillance system can be connected to an existing LAN of the building, and the switching centers of the system can be several in different parts of the building (depending on the capabilities of the LAN of the building), which reduces the number of materials and the timing of work, in contrast to the analog system in which All cameras are reduced to a single DVR. So, with the help of a switch with POE function, video cameras and a small amount of cable and mounting materials, it is possible to organize a modern video surveillance system in a short time, which can be easily scaled in the future.

For IP-system (including security television) it is enough to have a local computer network, which is usually always available and buy a switch with the function of the POE. Another advantage of digital video surveillance systems is the ease of their scaling and improvement. To effectively manage them, special programs are used that have the necessary functions.

 For small objects, where a small number of cameras (from 4 to 8 pieces) are enough, the sale of analogue video surveillance with a budget cost is optimal.

Services for installing video surveillance systems (analog and IP) in Atlanta and other cities are successfully implemented by JNL Systems. Depending on the requirements and wishes of the customer, we not only sell video surveillance systems, but also perform a full range of related activities:

All the works performed - research, recommendations on the selection and sale of video surveillance systems, calculation of the required amount of equipment and consumables, design of the project and installation of the system are performed by the specialists of JNL Systems company in a qualitative and strict manner within the agreed time.

In recent years, a large number of systems of different manufacturers, both domestic and foreign, have appeared on the Russian market of access control systems (ACS). These systems are able to satisfy the most demanding customer. To choose a system suitable for your tasks and requirements, you need to approach the problem of choice comprehensively: you can not be guided only by the price of equipment, you also need to consider other features of the ACS system, warranty service life, the ability to create employee reports, expand the system in the future. And many other parameters.

In this article I would like to give useful information, at the choice of the access control system - ACS.

The access control system is beginning to become an integral part of everyday life. If your office is located in a business center with a large number of neighbors, or on a crowded street, naturally there is a desire to limit access to unauthorized persons. Agree, do not feel comfortable when the door to your office is open to all comers. "At the dawn" of access control systems, you would simply install an audio or video intercom with a lock and ask the secretary to open the door, but this solution is possible with a small number of employees and visitors. If the number of employees is more than a dozen it already makes sense to think about installing an access control system.

The main points of the construction of ACS

Before discussing the construction of the system as a whole, and the features that you may need in your particular case, consider the most common components of any of them.

Any ACS system consists of the following functional elements, we begin their enumeration in terms of the significance and interchangeability, starting with simpler elements.

All access systems have an access key - an identifier, which is necessary to determine the rights of the user who owns them. Currently, non-contact plastic cards in the main EM-marine format are widely used. Compared to the RFID-identifiers of Proximity, Mifare or iClass standards, Em-Marine cards have the lowest cost with the same functionality.

The reader is a device necessary for transferring information from the identifier to the controller. Depending on the place of installation, the readers are street and internal, there are readers in the vandal-proof design.

Actuators are locks, latches, turnstiles, wickets, barriers and other devices that are controlled by the controller and block access. The choice of a specific type of device must be made in accordance with the tasks that need to be protected or blocked.

The main link in the operation of any access system is the controller, the capabilities of the entire system depend on its capabilities in the first place. All controllers can be divided into two groups: stand-alone and network.

Offline controllers do not have the ability to connect to a personal computer and configure the access parameters of the controller using a PC. With the use of such controllers, it is impossible to take into account the working time, set the time of passage (since the controller in this version either opens the door or not). Basically, they are configured with the help of a master card, through which the keys of access cards of employees granting the right of passage are added to or deleted from the controller's database.

Network controllers, devices, united by their own network and connected to the computer through the means of a network interface. They are configured using software, they also betray all information in real time to the computer, and can be controlled from the workplace. Network controllers are necessary for the organization of work time recording, recording of events occurring in the system and integration with other security features, such as security and / or fire alarms, video surveillance. It is also worth noting that nowadays more and more network access systems have the ability to connect to a PC not through a network interface, but by connecting controllers directly to an existing Ethernet network. On practice, the following situation often arises that the customer believes that the concept of a network controller means the ability to connect controllers to an Ethernet network, although this is not correct, and only means having a network and connecting to the computer through a network interface.

When choosing an access system, it is necessary to take into account the functionality of the system, which mainly depends on the Software. The software should be user-friendly and understandable in handling. You should also take into account the maximum number of controllers in the system, if you need to further expand the system, the flexibility to configure the system for your specific tasks, the ability to build various reports, the ability to connect additional workstations to configure and administer the ACS.
