Our Commercial Door Entry Solutions

Survey, Design & Installation

We start with a site survey to confirm:

  • how visitors arrive (gated entrance, shared entrance, rear door)
  • who needs to answer calls (homeowner, multiple tenants, mobile users)
  • what you need to control (main door, side door, gates, barriers)

Then we design a door entry system that’s secure, reliable and easy to use.

Video door entry (see and speak to visitors)

Ideal for front doors, side entrances and gates. We can specify systems that support:

  • clear video at the entrance
  • two-way audio
  • night vision/low-light performance
  • multiple indoor monitors (if required)
  • secure door release (maglock/strike) where appropriate

App-based door entry (answer from your phone)

For many homes and blocks, app-enabled systems allow authorised users to:

  • receive calls to a smartphone
  • speak to visitors remotely
  • manage access (where supported)

Audio intercom (simple, reliable entry control)

A great option when you want straightforward visitor screening and door release without video.

Multi-occupancy systems for flats and apartment blocks

We install and support door entry for blocks, including:

  • multiple apartments/handsets
  • trade buttons and timed access (where appropriate)
  • fob/keypad access integration (if required)
  • visitor management options depending on system

Door Release, Maglocks, and Secure Hardware

We can supply and install the correct locking hardware for controlled entry, including:

  • electric releases / electric strikes
  • magnetic locks (where appropriate)
  • push-to-exit and request-to-exit devices
  • compliant egress solutions (confirmed at survey)

Upgrades and Replacments

If you already have an intercom/entry system, we can often:

  • repair faults (audio issues, door release problems, power faults)
  • upgrade older panels/handsets for better reliability
  • improve video quality and night performance
  • take over maintenance for existing systems

Maintenance and Fault Support

Door entry systems are used constantly — so reliability matters. We offer maintenance and responsive support to keep:

  • call quality clear
  • entry panels working
  • door release functioning correctly
  • permissions and user lists up to date
