Usually high rise buildings house a combination of business, residential, retail outlets and leisure facilities. Each individual entity is concerned about who has access to its office or space. These mixed use buildings are contributing to the growth of access control systems. Access control is a secure system that monitors objects or people throughout a complex, a building or any confined space effectively providing electronic records of when and where users enter and exit. The basic job of the security personnel remains to regulate and monitor these access control system and ensuring each authorized person carries their access card with them at all times. Visitors can be reported or guided to the reception and given a visitor’s pass, which is pre encoded to only allow them access to certain areas.Access control is not just about technology and systems. These access control technology is only as effective as the person using it. Keeping this in mind, the management need to make sure the person using the equipment has received the right training.One should also consider the possibility of a security breach. If the security personnel is well trained, if an intruder is observed using CCTV, or an alarm is triggered, the security guards may be able to contain the situation, locking down access system and trapping the intruder.These access cards should be issued and used correctly in order to monitor movement within a building. As technology develops and evolves, more intricate and advanced methods of security systems are being implemented in access control domain.Radio Frequency Identification (RFID) uses the radio frequency to identify itself with the RFID reader. It stores and retrieves data using devices called RFID tags, proximity cards or transponders. These tags can be attached to an object, animal or can be carried by a person for identification or tracking purposes.If this RFID technology is coupled with smart cards, multiple information can be stored and also linked to various technologies and applications. High-frequency RFID tags can be used in applications like building access control and hence replacing the previous technology like magnetic strip cards or barcode cards with proxy cards.These proximity cards or intelligent access control cards can automatically detect when authorized personnel are approaching the building and validate their entry or exit.Access control system can also be integrated with various biometric devices. Biometrics analyses unique traits of an individual’s body part like eye iris scan, fingerprint, hand geometry, vein recognition, voice recognition, face recognition etc in order to authorize access.
DOOR ENTRY AUTOMATION SYSTEM: RFID CARD BASED
While installing Door for small businesses or large corporations one of the major factor is how to do Automation of the door entry system. We are the supplier and installer of Door entry automation systems. How the door entry system works is as follows, When an RFID card is shown to a reader, the reader sends the credential’s information, usually a number, to a control panel, a highly reliable processor. The access control panel compares the RFID card credential’s number to an access control list, grants or denies the presented request, and sends a transaction log to a database. When access is denied based on the access control list, the door remains locked. If there is a match between the credential and the access control list, the control panel operates a relay that in turn unlocks the door. The access control panel or door entry system control panel also ignores a door open signal to prevent an alarm. Often the reader provides feedback, such as a flashing red LED for an access denied and a flashing green LED for an access granted.
