Access Control System

Access Control System

An access control system (ACS) is intended to secure sanctioned access to an enclosed area and to keep record of working time.   


An Access Control System (ACS) will enable visual control of entrances to and exits from enclosed areas and will even record any attempts by employees or visitors to access restricted areas/premises within a guarded facility. Along with access restriction, an access control system will make it possible to assign an individual working schedule to each employee and to save and eventually examine the information about the events of a day. Such systems may operate autonomously and in connection with a computer. Depending on the size of a facility, the number of premises, and the number of personnel, particular types of equipment and software can be selected.

An access control system as a part of a general security system will make it possible to:  

Preclude access of unauthorized visitors to the company grounds. The system will show a photograph of a visitor on the monitors watched by the security personnel; and will allow the employee access in strict compliance with their working schedules; it will also take record of the working hours;  
Provide automatic access to various premises only for the personnel listed on the access permission list for each of the guarded premises;
Produce event logs. 

An access control system comprises the following components:

  • Core elements (PC, controllers, programming unit, and readout devices); 
  • Actuating elements (electromechanical locks, electric locks, electromagnetic locks, and turnstiles);
  • While selection of the main equipment depends on the complexity of the facility to be guarded and on the number of users within the system, the actuating elements depend on the material of the surface where they will be mounted, with due regard to esthetical details.
The present-day ACS are easily integrated with the 1C-based accounting tools (for the purposes of working time sheets) and with other security systems. ACS are also used in the field of entertainment business in order to provide paid access and to ensure the payment of fees where it is interesting to apply a uniform system of payments (such as a single card with recorded data equivalent to an amount of money); these may be public skating rinks, ski resorts, etc. 

When selecting a security system, it is important to remember that security systems are prone to technological obsolescence and to becoming more vulnerable to illegal intruders. Year after year, more and more advanced access tools and methods become available to deceive a security system and to cause damage through stealing some material values or information. On average, the expected service life of a security system is normally 5 to 10 years, and the system will require modernization or even complete replacement after such period expires (depending on what type of equipment was initially installed). 

The efficiency of access control system increases significantly when integrated with video surveillance and alarm systems.  

For the purposes of servicing a large facility, it is desirable to install an automated security system that consists of:

  • fire alarm system;   
  • voice-based fire alarm system;
  • intrusion alarm system;  
  • security video surveillance system; and
  • access control system 
For the purposes of integration of all those components into a single automated system, the Building Integration System (BIS) software set is designed. 

This system is an integral platform to ensure the linkage between all security systems and some other systems, such as the technical equipment required for regular operation of duty shift services and dispatching departments.
