Mobile access to multiple locations

The company integrates systems and designs bespoke solutions to meet each customer’s needs.

Darke & Taylor wanted an access control system that would only require one credential for six sites across the south of the U.K. Mobile credentials were a great solution, eliminating card and key replacement costs; and Suprema had the answer.

A central security network links multiple sites across VPN connections, allowing the Suprema CoreStations to talk to the remote server. CoreStations were used as controllers to keep RS485 connections and chains to a minimum, enabling extensive expansion capability in each location.

Mobile credentials were used to prevent employees from losing their credentials and creating a security risk. People do not generally lose their mobile phones, so this keeps the system a lot safer. Credentials can be issued to visitors before they access the location, eliminating the need to visit security to receive physical cards or fobs.

Access through the cloud

Security is installed in multiple locations with access to the BioStar 2 software through the cloud so that they can open and close doors remotely, allowing the client to move freely between rooms and properties. An Airfob patch was attached to the existing card reader to enable mobile credentials to be transferred into a Wiegand signal. This allowed a small reader to be housed inside the video entry panels to the property, keeping the equipment to a minimum, while keeping the entrance looking neat.

Remote Gate needed to be added to the access control system, which had minimal space inside the enclosure housing the panel. As a CoreStation would not fit, a door module was used to connect back to RS485, allowing a smaller power supply unit to be installed.

Two XPass D2 Rev 2 readers were installed for ‘in’ and ‘out’ to allow security to monitor if anyone is left on the premises. For example, in the event of a fire, they can check that everyone is safe using the roll call feature.

Key benefits of the solution

• Centralised system for all sites, so employees do not have to carry multiple credentials for different locations.

• Easy way for security to know where staff are in the client’s portfolio of properties.

• Easy enrolment and which can also be organised before new staff enter the site or visitors arrive.

• Confined 4-door solution in one box, minimising the space required for control panels.
