ДИСС

The access control systems (ACS) is a hardware-software complex intended for control / limit of access to facilities, on the territory, zone, etc. of an object, in accordance with its internal regulations. ACS is one of the systems that directly determine the security level at the facility. In addition, ACS can perform tasks of gathering statistics and monitoring such as: determination of the total number of people on the facility; accounting staff work time, keeping track of the certain individuals’ location, usage of capacity in halls, platforms, etc.

In general, the ACS has a centralized structure: server part, controllers, and execution unit. (Large-scale ACS is based on several interacting subsystems, which have the structure described above). Actuators are the turnstiles, automatic gates, barriers, motorized gates, electronic locks, etc. Each actuator works in tandem with the ID reader. Ids are the codes that can be marked as bar code, recorded on a smart card (bracelets), are based on biometric data. In normal operating conditions, the decision to permit or ban the passage of a given identifier makes server. This allows system management and monitoring in real time. Controllers are required to optimize the readers’ communication process with the server.

The composition and number of ACS elements depends on the specificity and scale of the object on which the system is installed. For example, in the capacity of controllers can act a purely hardware as well as server computers; in the capacity of a transport network can be used a LAN as well as individual, as a rule, specific data networks. Also, object specificity determines a list of systems that require integration with (video surveillance, fire alarm systems, ticketing systems, etc.).
