Preserving your privacy or property has become quite an issue nowadays. Do you feel your home is no longer a safe place, or that your trade secrets could become compromised? Do you want to keep unauthorised personnel out of some areas? Perhaps you already have some sort of access control system, but it isn’t suitable? Maybe you just want to know who’s ringing your door bell. We can help you deal with any of these situations, and more.
In physical security, the term access control refers to the practice of restricting entrance to a property, a building, or a room to authorised persons. Physical access control can be achieved by a human (a guard, bouncer, or receptionist), through mechanical means such as locks and keys, or through technological means such as access control systems, which control electronic or mechanical locks.
The most commonly used access control devices are:
Typing in the correct code will allow the lock to open. A keypad works in conjunction with an electronic door release or an electronically operated lock. This solution usually looks nice and is suitable for heavy traffic.
In this category, one also finds the widely sold digital mechanical latch locks. Three locks dominate the market:
The Lockey-type medium duty latch lock:
The Unican 7000 series medium duty latch lock:
The Unican 1000 series heavy duty latch lock, suitable for heavy traffic:
Holding a small fob or token up against the fob-reader plate will send an electric impulse to the door lock to release. The fob readers can be tailored so that the door would release simply by sensing the presence of the fob your pocket or handbag. A fob-reader works in conjunction with an electronic door release or an electronically operated lock. This solution usually looks nice and is suitable for heavy traffic.
Swipe card systems
Swiping the card through the swipe card reader will send an electric impulse to the door lock to release. A swipe card reader works in conjunction with an electronic door release or an electronically operated lock. This solution usually looks nice and is suitable for heavy traffic.
The only commercially widely available form is the fingerprint reader. Upon installation the prints of 1 or 2 fingers per user are programmed into the reader. Presenting the correct fingertip to the biometric reader plate will send an electric impulse to the door lock to open up. A biometric reader works in conjunction with an electronic door release or an electronically operated lock. This solution usually looks nice and is suitable for heavy traffic.
The headway this product makes is slow, mainly because solutions 1, 2 and 3 work quite satisfactorily.
Access control with computer feedback
If within your organisation you control more than just a few fob-readers or card-readers, then it may be suitable to have them administered centrally by wiring all readers to feed back to a central computer. This will make it very easy to add or delete fobs/cards or, for example, to set them up to work at certain times on certain readers only. While the installation and cabling tend to be involved, the end-result is usually incredibly well received.
Solution:An accountants’ office manager noticed an inexplicably quick depletion of some of their office supplies. These were kept in a separate room, which was never locked.
Metrolocks installed a medium duty digital mechanical latchlock. Only a few people were entitled to know the code. After the installation of the access control system thefts stopped forthwith.
A gym found that the moisture in the air near the changing rooms repeatedly wreaked havoc onto their existing heavy duty mechanical digital latchlock: It had to be replaced nearly every year.
Solution:Metrolocks installed a moisture resistant keypad with a latchlock and an electronic door release. This access control system has now been in place for 5 years with no repairs whatsoever.
The management of a large block of flats felt that over the years their key-security was compromised by numerous tenants not returning their keys, when they moved out. The cost of changing all main entrance and back door locks every few years was considered prohibitive in view of the great number of keys required.
Solution: Metrolocks installed a fob-reader onto every entrance door and wired all of them back to a central computer. The porter can now manage with ease and immediate effect all the fobs, which need to be added for new tenants and deleted for departed tenants. As a result of this access control system installation, the tenants’ confidence in the building’s security improved greatly.
A busy pub kitchen had a simple fob-reader installed, to avoid guests erring into the kitchen. Having to hold a fob up against the reader proved impractical for staff carrying dirty dishes back into the kitchen.
Metrolocks installed a proximity reader near the door, which was able to read the employees’ fobs from a distance of up to 1 meter. When staff now approaches the door, the lock buzzes open on its own.
A hospital needed a vital area secured by means of a keypad. Even though power-cuts are an infrequent occurrence, the management was very keen to avoid any problems resulting from electricity supply issues.
Metrolocks installed a heavy duty Unican digital mechanical latch lock. This type of access control system is suitable for hospital use due to sturdy build of the lock that needs no electricity.
Problem: A swanky model agency lost their bouncer and was left with a rimless armour-plate glass door and no easy way to add locks to it. In addition, the area leading from the door to the receptionist could not be cluttered up by a cable-run for any access control.
Solution: Metrolocks installed a magnetic lock to the top of the door. It was made to hold to the glass by a specialist bonding agent and by a springy steel pressure-plate. A little wireless receiver was added to the magnet and a transmitter installed to the receptionist’s desk. Pressing the button on the wire-free transmitter sent a signal to the receiver, which then released the door. This elegant installation has so far chalked up four years of trouble-free operation.
