Access Control Systems
Biometric Systems
Biometric
systems are undoubtedly the future of access control systems and are being used
more and more as the technology becomes more available.
Systems include retina (eye) scanners, fingerprint readers, palm scanners, voice
recognition and face recognition systems, fingerprint and palm readers in
particular are becoming highly favourable to offer a strong security solution.
Biometric systems cancel out security issues from stolen or lost cards and fobs
or shared pin numbers, as well as cancel out future recurring costs due to wear
and tear. Biometric systems are now surprisingly affordable due to recent
developments allowing for mass production of the products and are common place
in retail stores and public environments such as nurseries and schools.
Whether
it be to make announcements in a retail unit, ward-off intruders from a
construction site or to broadcast messages throughout a school
Crism can
tailor a system to match your requirements.

Key Fob and Swipe Cards
Key fob and swipe card systems are the most common form of access control in
commercial sites and previous situations when Crism have installed these
systems range from offices to colleges to construction sites to stock rooms.
As with biometric systems, key fob and swipe card systems can be used as a
stand-alone system or can be connected to work together through a centralised
system on a dedicated or multiple computers. Using specialised software
different functions can be utilised to enable access to certain areas with
specific cards/fobs or to allow certain cards/fobs to operate at specific times
for example.

Pin Entry Systems
Pin entry systems are perfect for operation on single door systems protecting
less secure areas and are the most cost effective means of enabling access
control.
The assigned manager of the system will have the ability to change the pin whenever they feel it is necessary.
Protection from fire is crucial for any business and Crism can provide a
comprehensive system to ensure that minimal disruption and accurate detection.
P4 Control Systems
Access control can be fitted to existing doors or Crism can install new
custom methods of entry.
For example, using an existing door it may be appropriate for the access control
to trigger an electro-magnetic lock or it you may require for a more custom
approach incorporating a turnstile.
