Identify visitors before granting access

A door entry system lets you decide who enters without immediately opening the door. We install telephone access controls and video entry equipment for homes, commercial premises and industrial sites. Video systems allow an occupant to see a visitor, while audio equipment provides voice confirmation before access is released. We assess the main entrance, staff doors and any controlled internal areas that need separate permission. The design also considers user numbers, visitor routines and the most practical positions for internal handsets, screens and release controls.

Entry equipment planned as one working system

We begin by examining the entrance, door hardware and route for power and communication. After agreeing audio or video verification, we position the external unit and internal controls, install the cabling and connect the access-release equipment. We then test calls, images and door operation before showing authorised users how to admit or refuse visitors. Our team has more than 50 years of combined entry-system experience, giving us depth across different property types and access arrangements. Maintenance and fault diagnosis are available after installation.

Frequently asked questions

Should we choose audio or video door entry?

Audio entry allows voice confirmation, while video lets an authorised user see the visitor as well. The right choice depends on the entrance, lighting, user needs and desired level of verification. We compare both options during the survey.

Can one entry system serve several users?

Yes. We can design suitable systems with several handsets, screens or authorised users. We need to understand the number of occupants, entry points and visitor process first. The final design also depends on door hardware and the required access permissions.

What happens during door entry commissioning?

We test communication, images where fitted, release controls and door operation. We then demonstrate how authorised users answer calls and grant or refuse access. Any user-specific settings are confirmed before the system is handed over.
