Access Control

Access Control

Who can open which door, and when — credentials, readers and locks commissioned as one entry system.

Entry control

Controlled doors without treating every opening the same.

Access control is the entry layer: readers, credentials, locks and the permission set behind them. A single door with a keypad is a different job from a multi-door workplace with staff turnover. This page covers that entry layer specifically — alarms sit on their own page, and the broader Security & Access page introduces the category.

Door survey

What we assess before a reader goes on the wall

  1. 01

    Door and frame type

    Timber, metal or glass doors — and whether the frame can take a strike or maglock cleanly.

  2. 02

    Who enters

    Staff, residents, visitors and after-hours access — each affects credential type and schedules.

  3. 03

    Power and cabling

    Reader power, lock release and network paths planned together so the door unlocks reliably.

  4. 04

    Credential approach

    Keypad, card or fob — matched to turnover and whether codes need changing when people leave.

Credentials

Keypad, card and fob options matched to the building

Keypads suit sites where issuing cards is unnecessary or as a backup credential. Cards and fobs work better when permissions need to be issued, revoked and timed. The reader and lock are specified together so unlock behaviour is reliable — not a separate afterthought.

How people enter

Reader types for different entry habits

Keypad access

Codes for sites where issuing cards is unnecessary, or as a backup to a credential. Codes are planned so they can be changed when people leave.

Card and fob access

Credentials that can be issued, revoked and timed — typical for workplaces and multi-tenant entries where permissions need to stay current.

Permissions and locks

A permission set that can survive staff changes

User permissions
Who can open which door, and during which hours — designed around real occupancy, not a default that never gets updated.
Controlled doors
Electric strikes or maglocks specified with the reader so unlock behaviour is reliable every time.
Credential management
Add, remove and time credentials without a site visit every time someone joins or leaves.

System integration

Doors that can sit with alarms, CCTV and intercom

Access control often shares a brief with intrusion alarms, cameras at the same door, or an intercom that needs to release the lock. Those systems have their own pages; the install is cleaner when they are scoped together from the first site walk.

Access control questions

Common questions about controlled entry

  • Often yes. Many timber and metal doors can take a reader and electric lock if the frame and power path allow a clean install.
