ACCESS CONTROL SYSTEMS
DATABASE / SERVER / WORKSTATION
The access control database is a large quantity of indexed digital information. It can be searched, referenced, compared, changed or otherwise manipulated with optimal speed and minimal processing expense. This is a logical organization of the information which have all the access control information of hardware, functioning, and records, the software use this information to control and provide information to the user in a natural language the way the user can interact with the system and configure it to a desired behavior.
Every access control system needs a server where the permissions are stored in an access database. As such it acts as the center or “brain” of the access control system. It is really the server which makes the decision if the doors should unlock or not by matching the presented credential to the credentials authorized for this door. The server tracks and records activity and events regarding access and allows to pull reports of past data events for a given period of time. If a local hosted access control server computer is used, it is typically a dedicated machine that runs the access software on it. The access control server is the master device which send the database to all controller board and program it for a desire functioning.
The access control server will help you to migrate you premises information as user, door, schedules, etc. in case you want to change the controller’s system to another system, also the server can revert any inappropriate change to de information by a restoring process from a previous backup. The server is the device also how send/receive data to access control workstation and interact with them for real-time monitoring, access point controls, and schedule control. Newer access control system will allows workstation to interact directly to the controller over IP/Ethernet, before the regular communication was RS-232 which does allow concurrent connection to the main controller.
TYPES OF ACCESS CONTROL SERVERS SOFTWARE
Operative System-Software Base:
This Server model consist on a desktop application which run in the operative system and for the user to interact with the system need to be locally in front of the computer or by a remote desktop application which allows you to control the computer as locally.
Web Server Base:
As part of the unified process of migration of software and services to cloud, the access control systems will begin to transform the model of installation and in the future the software will move to a cloud system and the controllers will have encrypted communication with the servers and theworkstation will be able to communicate from anywhere at any time with the appropriate credential and configuration.
INTRODUCTION TO ACCESS CONTROL
In the fields of physical security, Access control is any mechanism or system that is used to control access into or out of any area through the authorization or revocation of rights to physical or logical assets within a business or home.
ACCESS CONTROL TESTING READERS
Access control card readers are one of the major component of an Access Control System. These are used to read the encrypted data on an access card and allow or deny access based on the card information with the feedback from the control panel.
ACCESS CONTROL: CREDENTIALS
The standard form of today’s access control is an “access card” instead of the standard metal key and lock system to grant access to the secured area. There are different types of access cards and each require an access control system card reader.
ACCESS CONTROL: RFID
RFID stands for Radio-Frequency IDentification. The RFID device serves the same purpose as a bar code or a magnetic stripe; it provides a unique identifier for that object. RFID is fast, reliable, and can be read from up to several feet away.
ACCESS CONTROL: SENSOR
Motion sensors are found everywhere today and function by detecting a vehicle or person approaching an exit and unlock the door. Due to their motion sensor they can trigger motion and thus unlock the door right when you walk up to the door to exit the space.
ACCESS CONTROL: CONTROLLERS
Access controllers are split through many types of control models an features, all of them providing the essential services of authorization, identification and authentication.
ACCESS CONTROL: DATABASE-SERVER
Every access control system needs a server where the permissions are stored in an access database. It is really the server which makes the decision if the doors should unlock or not by matching the presented credential to the credentials authorized for this door.
KEYLESS DOORS: MAGLOCKS/STRIKES
Magnetic locks and electric strikes are electrical hardware devices used to maintain the security of a door opening. Both of these devices can be activated by a range of tools, including passcodes, biometric readers, keycards or buzzers.
