SECURITY SYSTEMS
They are suitable for timber , metal and glass doors in both swing and sliding door configurations and are available in various sizes , types , finishes and shapes .
Technology such as Bluetooth Low Energy “ BLE ” for operation with mobile phones can now be used thus removing the need for cards or fobs . Near Field Communication “ NFC ” can also be enabled giving a more secure connection between the phone and the lock . Most apps require you to open the app after unlocking the phone thus giving an extra level of authentication to increase security .
Wireless access control can be used at home using apps to assign users and home connection set up can use an existing wi-fi network , Bluetooth or a separate hub and existing wi-fi network plus Z-Wave or Zigbee technology .
Reading Technologies
There are a number of different technologies for authentication that can be used to gain access within an access control system . Each technology has a different level of security from the lowest such as a common PIN code through to medium such as a token or card , right up to the highest such as biometric readers .
As it gives a high level of security and is very user friendly and contactless , biometric technology is being rapidly adapted to make buildings more accessible and still give a high level of access control . From the very first commercial application for a fingerprint reader in 1984 the market has regularly seen the introduction of new products and applications . Biometrics is measurement and analysis of the unique physical or behavioural characteristics used to recognise humans . It works by unobtrusively matching patterns of live individuals ’ data in real time , against enrolled records . Biometric data is initially read with an ‘ enrolment ’ reader and the data is then ‘ encoded ’ into a template which is usually stored in an access control database or on a smartcard for later use . The encoding process ensures that the data cannot be reproduced from the template , only compared against a recently read sample for a pass / fail result . Biometric sensors are either contact ( i . e ., the user needs to touch the sensor ) or contactless ( i . e ., the user does not touch the sensor ) technologies .
In large scale systems fingerprint readers has transferred gradually over to facial recognition using HD camera technology from the CCTV systems linked to the access control . The following features are all relevant in this area :
• “ Digital On-boarding ” - this is the integration of digital information into access control systems which use AI- Powered identity verification . This has become a feature of many different offerings from manufacturers . This can be completed remotely meaning someone can be added to a system in advance .
• Geo-Fencing of areas which is when invisible perimeter lines are set up in a system so an alarm is activated if someone crosses these lines into an area where they should not enter .
• 3D facial recognition has become a part of people ’ s lives from their mobile phone unlocking , and this technology has become common in access control systems as a method of contactless access control .
• Face Recognition Vendor Test ( FRVT ) has a system of testing the speed a system can recognize a face when approaching a reader and allow or
deny access to the user . Most systems can do this in less than 2 seconds .
• Biometric Passports are becoming the norm now so security through airports has increased with verification , in some airports the screening is checked again at the boarding gate to the aircraft .
• 3D Matrix Face recognition software takes multiple spots on a person ’ s face and creates a digital signature which can be stored as a reference in a database , using digital onboarding . It can deal with facial hair changes or the wearing of hats and glasses . The system can have RFID cards or mobile phones linked to the account so a higher level of security can be achieved , and the ID card can ’ t be given to another person for access .
