How Intercoms Fit Into a Commercial Door Entry Installation
Intercom systems are a core element of modern commercial door entry system installations. While door entry controls who can access your property, intercoms enable secure, two-way communication between visitors and authorised personnel before access is granted.
Intercoms as Part of a Broader Installation
During a commercial door entry installation, we assess your site to determine the best intercom configuration, whether audio-only, video, or IP-based systems, and integrate it seamlessly into your access control setup. This means:
Intercom hardware is installed alongside entry panels and access control units
Wiring and networking are coordinated for reliability and compliance
Communication functions link with remote management tools and smartphone apps
Benefits of Integrated Intercom & Door Entry Systems
By combining intercom communication with your door entry controls, you get:
Clear visitor verification before granting access
Remote control via apps or wall panels
Enhanced security for staff, visitors, and assets

Common Door Entry System Misconceptions
“They’re only for large apartment blocks.”
Door entry systems are widely used in small offices, converted buildings, and shared commercial spaces.
“Audio-only systems are outdated.”
In many cases, audio systems are still reliable, cost-effective, and perfectly suitable.
“They’re difficult to use.”
Modern systems are designed to be simple and intuitive for both visitors and occupants.
FAQs
-
In practical terms, a door entry system allows occupants to see, hear, or speak to visitors before granting access remotely.
A door access system controls who can enter a building or room. It can use intercoms, keypads, fobs, or smartphone apps to verify and allow access. These systems are commonly used in homes, flats, offices, and commercial buildings to enhance security.
-
Door entry systems typically include an intercom, a camera or speaker at the entrance, and a control unit inside the building. When a visitor presses the call button, the occupant can see or speak to them and remotely unlock the door if required - either through a handset, wall panel, or smartphone.
-
Some older or GSM-based intercom systems can be programmed to call a landline or mobile number when a visitor arrives. Modern systems often use smartphone apps instead of traditional phones, offering more control and features such as video and remote unlocking.
-
To secure an entry door, combine strong physical security (like a solid core door and quality deadlocks) with a door entry system or intercom. Systems with video, remote lock release, and smartphone alerts can deter intruders and prevent unauthorised access.
-
Yes! Many modern door intercom systems, such as Hikvision or Telguard GSM, allow you to manage entry through a mobile app. You can speak to visitors, view live video feeds, and unlock the door from your smartphone, even when you're not at home.
-
For offices and commercial premises, a multi-door intercom system with coded or proximity access is ideal. Business intercom systems often integrate with CCTV and fire safety systems, and support features like visitor logs and staff access control.
-
Yes! Wireless and GSM intercom systems are perfect for properties where cabling is difficult or undesirable, such as listed buildings. They use mobile networks and can often be installed with minimal disruption.
-
Absolutely. Many systems — including Hikvision and Paxton — are modular and scalable. That means you can add more doors, users, or access methods (like proximity fobs or fingerprint readers) as your needs change.
