WHAT ARE THE CHOICES? ACCESS CONTROL
Access control systems are used to control and monitor movement around the site through access points. The main types of system are detailed below.
Remote operation:
A hand held or fixed transmitter is used to operate the system remotely.
This can be a fairly basic radio frequency device that is not recorded or
controlled or a more advanced transmitter that can be controlled by time
or date and its movements logged on a software based access control system.
This will allow you to monitor personnel or vehicle movements.
Automatic operation:
The system operates automatically on either entry or exit. This is usually
only used in one direction e.g. visitors who have previously been authorised
can leave without delay.
Keypads:
The system users can be issued with a PIN which when entered, will allow
either entry or exit from the site. This is the lowest form of security
and will not allow you to monitor personnel or vehicles. Codes can also
be shared.
Proximity access - fobs:
The system users can be issued with a fob which when presented to the reader
will allow either entry or exit from the site. On PC-based systems, a record
of the transactions is available for future interrogation. Systems can be
extended to cover internal and external doors.
Proximity readers:
This is the device that the proximity fobs are presented
to. The reader sends data to a terminal which determines if the fob is valid
for that entry point. Day and time restrictions can be placed on that point
and fob to restrict access as required.
