Access Control Systems
Eliminate keys, increase your level of security and convenience simultaneously
If your just looking for convenience with additional security at home or want to restrict and monitor access at work, we can help.
We also cater for high security installations that require such features as population count, muster lists, anti-passback, dual card entry or interlocking doors.
We can install standalone or integrated access control systems using latest technologies available. We also have a range of card and ID printers available.
Combination Keycode / Proximity Access Control
The Ness Combination access control system is a neat little unit. It can be used in a stand alone mode or integrated into your security / access control system.
For access, you can either enter a PIN or present a card or fob. Suitable for low to medium security applications. Ideal for front gates, to complement your intercom system.
Proximity Card Access Control
Proximity is the most widely used these days. Providing a cost effective medium level of security. By presenting an access card or fob to a reader, the card energises and presents a set of credentials to the reader, which the system can evaluate and determine whether access should be authorised or not. If so, then the system will unlock the door.
This system is given a medium security rating for a couple of reasons. Any given card is not guaranteed to be dedicated to one particular site. There could be a site somewhere, where when this same card is presented, could permit access. This is obviously a rare occurrence and unlikely, however possible.
The second reason is the proximity card will automatically transmit its credentials when it comes within range of a reader, so hypothetically, this card can be skimmed.
Skimming can occur if a perpetrator has a small reader in his pocket connected to a mini controller. They could brush past you and read your card without you even knowing. Once this card has been read, it can be reproduced, to allow access, posing as the original card holder.
Smart Card Access Control
Smart cards are very similar in operation to proximity cards with one unique difference in its operation. Unlike a proximity card, when it comes into range with a reader, before it releases its credentials, it will seek to match a high-level security code that is stored in the card and the reader. Once this security code is matched, will only then the card release it credentials to the reader for evaluation.
This eliminates the risk of skimming as the unique code is programmed in the card and reader at the time of programming the card and gives thus rates smart cards for a high security solution. Consequently the cost of this system is higher, as the cards and readers are more expensive, and a smart card programmer is required to programme cards
Biometric Access Control
Biometric or fingerprint readers are starting to become more widely used. They have always been considered expensive and suited very high security applications, where in some cases dual verification is required by entering a PIN and presenting your finger.
The cost of these units has come down considerably and are being considered for a higher number of new installations.
The only downside of biometric is if you cut your finger, you may not be able to get into work that day, if that’s a problem…..
