4. READER SECURITY TYPE
Depending on the level of security required, the readers comprise two
types: WITH integrated controller and WITHOUT integrated controller.
- Readers with integrated controller. Models: MDS/CAC.
Installation is easier but the level of security is lower by leaving the
control circuit on the exterior (of the reader). All devices connect directly
to the reader: lock-release, door sensor (if required) and exit button.
- Readers without integrated controller. Models: Wiegand-26/
Data Clock.
A door controller is required. This is installed in the interior area (secure
area) and the reader on the exterior. All devices are connected to the
door controller: the lock-release, door sensor (if required), exit button,
etc. and therefore are not subject to interference.
Readers are recommended for more secure applications.
KEYPAD. The user should enter a code on the keypad. It is the most
economical model as it does not use identifiers. The same code can
be used by various users.
PROXIMITY. The identifier is a card (similar to a credit card) or a
proximity fob. The identifier is swiped by the reader at a distance
of several centimetres. The reading is facilitated by means of radio
frequency data transmission. This is the easiest and most secure
method.
BLUETOOTH. Access control functions are provided by way of mobile
phones with Bluetooth technology. The telephone system itself identifies
the user. The advantage of this system is the reader's operating distance,
which makes it very useful for vehicle and pedestrian accesses.
BIOMETRIC FINGERPRINT. Biometric fingerprint access reader with
capacitive sensor. Identifies the user by its fingerprint (feature which
is unrepeatable and unique to each person), offering a greater level of
security than any other system using another type of identifier.
RADIO FREQUENCY. This technology is mainly used in
garage accesses given the flexibility allowed by the large
distance between the identifier (control) and the receiver.
3. READER TECHNOLOGY
There are several types of technologies depending on the
interaction between the identifier and the reader.
