How does an access
control system work?
case you own a
business, which requires a strict goods/personnel check on certain
pre-established ways, we suggest you should introduce a transparent and
effective access control system.
Usage of proximity/magnetic cards, access coded keypads as well as implementation of software suitable for goods and/or personnel flow check is the most frequently met solution worldwide.
The tendency of software integration of access control, first fire bursts, burglary protection and video surveillance as well transfer complex applications from the abstract range to the real one.
in the first phase in our country, access control carded systems have
proved as being useful and efficient within several branches such as:
- Several industrial units for employee
time and attendance purposes
- Surveillance of car access inside car
- Warning unauthorized access into
- Access into hotel rooms
to their thinness and reduced dimensions, cards have been already
worldwide used as identity cards, driving licenses, office personal
papers, etc. Card usage within access control systems remove key usage in
some situations and provide a stronger security due to the extended number
The same extended code number can be obtained by key combinations on the keypad or by linking a numerical code to a card.
order to process data from a network of doors controlled in such a way, a
computer should be used in most cases. Software versatility allows keypad
complex system operations, report producing referring to any of the fields
of the created databases.
Latest solutions allow integration within a complex burglary/fire security system of access control and closed circuit television systems. So, in fire situations not only employee evacuation control becomes possible, but also video surveillance and recording people inside a certain room, at a certain time.
Access control systems can be used both for preventing unauthorized access into certain quarters and recording people access into certain quarters as well. The picture below shows the way an access control system can be used:

access control system can function locally or in network.
When functioning locally, several users are allowed access through one door, respecting a certain program without the number of controlled doors being limited.
functioning allows information correlation by the access control main
units for the users to access pre-established ways according to
pre-established access programs. The system also allows monitoring the
access-controlled spaces by means of adequate software. If a PC is
connected to the network, then the next operations can be executed by
means of the computer software:
- System configuration;
- Real time door state
- Real time acknowledgment
of events produced;
- Previewing events
produced during one day, one week or even years;
- Event arrangement according to certain criteria, event displaying on screen or their sending to the printer.
An access control system can function by:
If the card or the user code is recognized, then the access control system will trigger the door-locking device and allow access.
case the door stays open for a longer time than it was programmed to,
after an authorized entry, the system will activate a warning device.
case of braking in, the system will trigger an existent alarm system or a
The installed access control system may be interconnected to an existent burglary/fire alarm system. It may also command various automation devices (turning light on, ventilators, air conditioning, etc.)
