Access Controls Overview

Durell Controls are specialists in engineering and installing modern distributed-hardware access control systems. These systems use common industry standards including Power-over-Ethernet (PoE), BACnet, and SQL databases to provide the customer with flexibility and scalability that is not practical with centrally-wired or proprietary-protocol systems.

Showcase: St Thomas-Elgin General Hospital

Durell implemented a multi-year rollout of a Delta Controls access control system at a London-area hospital. This system controls nearly 100 doors and is integrated directly with the hospital’s BACnet HVAC control system. Features and services provided by Durell include:

  • 24-hour emergency service
  • Global building emergency lockdown
  • Fire alarm interlocks (hardware and software) for life safety
  • Common operator interface with HVAC system
  • Normal/after hours locking schedules
  • Battery backup
  • Distributed controllers located at each door
  • Standard 26-bit Wiegand proximity cards
  • Shared cards with parking and drug access systems

Showcase: Parts Canada

A London-area warehouse contacted Durell to replace a failing centrally-wired access control system. Durell responded same-day to identify existing faults and provide options for replacement. The customer selected Durell to install an Infinias Intelli-M distributed access control system. Features and services provided by Durell include:

  • Merging existing card user database with new server
  • PoE-powered distributed controllers
  • Ethernet cabling and terminations
  • Zero interruption of service via incremental replacement
  • Configuration of software on virtual machine
  • Enabled customer-administered SQL database backups

Once the new system had proven itself, the customer tasked Durell with migrating an existing Infinias system in Calgary, Alberta to the same server. Durell was responsible for

  • Merging existing card user database with new server
  • Migration of controllers to new IP subnet
  • Decommissioning of old software

Although all tasks had to be performed remotely from London in co-ordination with customer staff in Calgary, the migration was successful.

Showcase: Trinity United Church

A London-area church contacted Durell to address some installation issues with an existing Infinias Intelli-M access control system. Durell responded same-day to identify existing faults, and consult with the customer about desired additional features. Durell was able to repair the faults immediately and quickly provide a solution for the extra desired features.

Durell Controls designs, installs, and maintains state-of-the-art digital power-over-Ethernet security surveillance camera systems. PoE camera systems allow utilization of existing cable and switch infrastructure, and simplification of any required new cabling. Digital HD cameras offer image clarity and colour depth impossible to achieve with analog camera technology, even at equivalent resolutions.

2N PoE Intercom units with built in keypad, card reader, and camera is another layer you can add to your security system. 2N intercom units also integrate with Milestone’s software.

Milestone’s Xprotect family allow seamless integration with Delta Controls’ access control system, adding yet more options for integration with lighting, access, and HVAC management systems.

AXIS Camera Station VMS is also used based on installation requirements and where only AXIS cameras are used.

Whether it is AXIS cameras or others that you need, Durell can supply your facility with the required hardware and software to meet your design requirements. Upgrading existing systems and utilizing existing cable is Durell’s way to reduce cost and provide you with the latest state of the art CCTV system.
