Access Control
In physical security, the term
access control refers to the practice of restricting entrance to a property, a building, or a room to authorized
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
1) Keypads:

Meadows
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:

lock, suitable for heavy traffic
2) Fob-reader
systems:

Meadows
Holding a small fob or token up
against the 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.
3) Swipe card
systems

Swiping the card through the
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.
4) Biometric
readers:
Locksmith Fresh
Meadows
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 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.
Intercom Systems
Locksmith Fresh
Meadows
Intercom systems are a ubiquitous
feature of both residential and commercial premises. If you need to know who is knocking on your door, then an
intercom system is a must.
Depending on the end-user's
requirements, intercom systems can be large versions for many users:
Locksmith Fresh
Meadows
This is a flush-mounted intercom
system, where the main part of the equipment is sunk into the wall.
Or they can be small, single-user
units:
Locksmith Fresh
Meadows
In this case, the entire unit
would be fitted onto the wall - this is a surface-mounted intercom system.

Intercom systems are audio-only
most of the time. Audio systems outnumber video systems by a factor of 20.
For commercial installations,
intercom systems are frequently combined with other means of access control, such as a keypad or a
fob-reader:
The intercom is for visitors,
whereas staff will be able to easily get in via the keypad.
As a rule of thumb, intercom
systems can have a trouble-free life-expectancy of between 5 and 10 years. As there aren't any moving parts,
they don't usually need a service contract.
