Door entry and entry phones

Entry phone installation in London for offices and commercial buildings of any size.

ACCL installs audio, video, telephone, keyless and IP door entry systems that let you see or speak to visitors before you let them in, and keep a record of who enters. We fit new systems, upgrade old ones and move systems when you relocate or downsize, across London, Kent, Surrey and the South East. Every project starts with a free on-site consultation.

Types of entry phone systems

Door entry systems we install.

We recommend the system from your building type, the number of entrances and tenants, and how you want to identify visitors.

Buzzer door entry

Panels with an employee directory, camera, microphone and keypad for full control over who comes in.

Video door entry

Live video of visitors, so access is given only to people you recognise.

Telephone entry

Visitors and staff call in before access is granted, an extra layer of security.

Keyless entry phones

Unique entry codes or a smartphone open the door, with no keys to lose.

IP and SIP intercoms

Entry phones that route calls to VoIP desk phones or a smartphone app for remote door release.

Multi-tenant directory panels

Visitors select and call individual tenants, with access codes, fob readers and central tenant management.

Door entry or keys?

How door entry systems compare with traditional keys.

Keys have served for centuries, but a door entry system gives far more control.

Planning your system

Things to consider before you choose.

These shape the design, and we cover each at the free consultation.

  • Size of the propertyLarger premises may need several systems to cover every entrance and exit.
  • Visual identificationIf visitors must be seen before entry, you need video or camera components.
  • Number of officesBuildings with several offices or companies may need a tailored multi-tenant system.
  • Traffic flowThe right system changes with the number of visitors and users each day.
  • Access points and cablingPanel positions can be limited by cabling or access; extra points and cables may be needed for the right protection.

New, upgraded or moved

New entry phones, upgrades and relocations.

Whether you need a new door entry system, an upgrade to an old one, or help moving or downsizing, we tailor the plan to what you need now and make sure the system can grow with your organisation.

An older audio entry phone can often be upgraded to video, or to an IP system that rings desk phones and smartphones. Door entry can also be linked to access control, so fobs, codes and the intercom work together at the same door.

  • Upgrade pathsAudio to video, or analogue to IP and smartphone entry.
  • Relocation and downsizingSystems moved or reconfigured when your premises change.
  • Planned for growthSpare capacity for new doors, tenants and users.

Door entry explained

Entry phone installation, in depth.

Entry phone systems for businesses of any size

A phone door entry system controls who can get into your premises, and can also record staff movements. ACCL installs door entry phones for businesses of any size, whether you need a new system, an upgrade, or help with a relocation or downsizing. Each installation plan suits your current needs and leaves room for growth.

Door entry versus traditional key access

Door entry systems usually give higher security than keys. Biometric scanning, keypads and RFID cards are much harder to copy than a key, which reduces the risk of unauthorised access.

They are also more convenient. A lost fob or code can be reprogrammed instead of changing locks, and users can let others in remotely. Monitoring shows who entered and when, which helps manage visitors and staff attendance. The upfront cost is higher than cutting a key, but fewer lock changes and less unauthorised access save money over time.

Video door entry for offices

Video entry lets reception or staff see visitors before releasing the door, so access is given only to people you recognise. Panels can include a directory, camera, microphone and keypad. For offices without a permanent reception, video calls can go to desk phones or a smartphone app. Babylon Health’s London headquarters and clinics are an example of video entry installed alongside access control on a network we cabled.

IP entry phones and smartphone door release

IP and SIP-enabled intercoms connect to your network rather than a separate intercom wire. They can integrate with VoIP phone systems, route calls to a smartphone app with two-way audio and video, and release the door remotely wherever there is an internet connection. They need suitable network cabling at each panel, which we install.

Linking door entry to access control

Modern IP entry phones integrate with access control for central door management, and with cameras for recorded visitor footage, so all systems work from one management platform. See IP security system installation for integrated systems, and our guide to visitor management and access control integration.

What affects door entry installation cost

Cost depends on the type of system (audio, video, IP or smartphone), the number of doors and tenants, cabling and access to panel positions, integration with access control and other systems, and whether an old system is being replaced.

After the free on-site consultation you receive a report and an itemised quote before any work starts.

Why choose ACCL for door entry

ACCL is a data cabling and security installer, so the cabling, network and door entry are delivered by one team. Our wider office work includes the Wi-Fi-first network for Tidraw’s Old Street office and almost ten years of structured cabling for Grant Thornton at 30 Finsbury Square. These are network projects rather than door entry installations.

Entry phone installation FAQs

What is a door entry phone system?

A door entry phone system lets visitors speak to staff inside a building before they are let in. Systems range from simple audio intercoms to video entry phones with a camera, and IP systems that route calls to desk phones or smartphones for remote door release. Entry phone and door entry usually mean the same thing for a business.

What types of entry phone system do you install?

ACCL installs audio entry phones, video entry phones with a camera, IP and SIP-enabled intercoms that integrate with VoIP phone systems, smartphone-controlled door entry, keyless code entry and multi-tenant directory systems. We recommend the most suitable system for your building type, number of entrances and tenants, and how visitors need to be identified.

Can entry phones integrate with access control and CCTV?

Yes. Modern IP entry phone systems integrate with access control for central door management, and with cameras for recorded visitor footage. ACCL designs integrated security so all the systems work together from a single management platform, and fobs, codes and the intercom can all open the same door.

Can I answer the door entry from my mobile phone?

Yes. IP-based entry phone systems can route calls to a smartphone app, so you can see the visitor on video, talk to them with two-way audio and release the door remotely from anywhere with an internet connection. It suits offices without a full-time reception and staff who are often away from their desk.

Do you install entry phones for multi-tenanted buildings?

Yes. ACCL installs directory-style entry panels for multi-tenanted commercial buildings, so visitors can select and call individual tenants. Systems can be set up with individual access codes, fob readers and central tenant management, which makes adding or removing a tenant a change in software rather than new wiring.

Can you upgrade an old entry phone system?

Yes. We fit new systems and upgrade existing ones, for example from audio to video, or to an IP system that rings desk phones and smartphones. At the free consultation we look at the existing panel, handsets and cabling, then recommend whether to upgrade or replace, and plan the work to keep disruption low.

How long does entry phone installation take?

A single-door entry phone can usually be installed in half a day to one day. Larger multi-door or multi-tenant installations may take several days, depending on cabling and integration. ACCL provides a programme of works after the free consultation and schedules the installation at a time that suits your business.

How much does door entry installation cost?

It depends on the type of system, the number of doors and tenants, cabling and panel positions, integration with access control, and whether an old system is being replaced. We do not quote a fixed price without that detail. After a free on-site consultation, we send a report and an itemised quote before any work starts.
