Manage Visitors Before They Enter
Door entry allows a visitor to request access without leaving an external door open or giving out a shared code. It is useful where reception is set back from an entrance or where a commercial building has several occupiers. The system needs to fit how visitors are actually received.
An audio system provides a conversation with the caller. A video system adds a view of the entrance, which can help staff confirm who is there before operating a release. The camera position needs to capture the caller rather than a bright sky or the side of a doorway.
We consider delivery drivers, contractors, unfamiliar visitors and staff working away from the main desk. Agree who can accept calls and who has authority to admit someone. Technology cannot replace a clear visitor procedure, especially in schools or buildings with restricted working areas.
Select A Suitable Call Arrangement
A single commercial entrance may only need one internal answering point. A shared office building may need a directory or separate call buttons for each tenant. The specification should state which device rings, what happens when nobody answers and whether calls can be redirected.
IP intercoms can use an existing network where that network is suitable and its administrator agrees. Some systems call an app or telephone service, with ongoing subscriptions or call charges. Others use dedicated internal handsets or displays that keep the arrangement more self-contained.
Check the location of the external panel, available light, background noise and the reach needed to press a button. A sheltered office doorway and an exposed delivery entrance need different housings. The system should also support the needs of people who cannot use an audio-only conversation.
Door Release And Safe Escape
The intercom and the lock form one entrance arrangement. The door must close properly and the release must work with the door construction and existing furniture. A worn closer or misaligned strike can make a new intercom appear unreliable even when its electronics work correctly.
For escape doors, entry control must be coordinated with the fire risk assessment. The Regulatory Reform (Fire Safety) Order 2005 is relevant to commercial premises in England. The government offices and shops guide explains that security devices must retain a suitable means of immediate escape.
We review the need for emergency release, interfaces and alternative ways to leave the building with the appropriate people. Do not rely solely on a reception button or an internet connection for escape. Any proposed changes to a fire door also need careful assessment before drilling or replacing hardware.
Survey, Installation And Handover
At survey stage, record the panel position, lock type, internal answering locations and cable routes. Existing intercom wiring may be reusable, but its type, length and condition need checking. Photographs can help prepare a visit, though a photograph cannot confirm the state of hidden cabling.
Installation should include protected wiring, correctly sealed external connections and an agreed method of maintaining controlled entry while work proceeds. At a multi-tenant building, notify affected occupiers and identify who controls the common entrance. Changes to call routing should be tested with the actual recipients.
Commissioning checks conversation quality, the visitor image, release timing and reliable door closure. Where a system uses a network or app, test the agreed fallback and access permissions. Handover should include equipment details and instructions for updating tenant names, managing users and reporting a fault.
Cost And Ongoing Responsibilities
The number of entrances, internal stations and tenants affects the budget. New cable routes, network equipment, replacement locks and power supplies can be significant parts of the work. A quotation should distinguish the intercom equipment from repairs to the door itself.
For app-based systems, check subscriptions, user limits and what happens if a service is discontinued. Ask whether the business owns the account and can change administrators. A system that depends on one member of staff keeping a personal phone available can be difficult to manage.
If visitor images or calls are recorded, consider the purpose, access permissions and retention arrangements for that personal data. Recording is not essential to every intercom. Tell us whether you need a new entrance system, a replacement panel or integration with access control when you enquire.
The Work, Step By Step
- Map The Visitor Route. Identify the entrance, answering points and the people authorised to admit callers.
- Check The Door And Wiring. Assess panel positioning, cable condition, power, lock compatibility and escape arrangements.
- Install And Route Calls. Fit the equipment and configure the agreed recipients and unanswered-call behaviour.
- Demonstrate The Entrance. Test sound, video, door release and closure with the people using the system.

Door Entry Questions
Can Door Entry Call More Than One Reception Point?
Door entry can call more than one reception point if the selected equipment supports the required routing. Options may include multiple internal stations, sequential ringing or approved mobile devices. Describe who should receive calls during different working hours and what should happen when the first person cannot answer before the system is specified.
Can An Existing Door Entry System Be Replaced?
An existing door entry system can be replaced after the panel, cabling, lock and power supplies have been assessed. Keeping old wiring can reduce disruption when it is compatible and sound. The quotation should identify retained parts and any restrictions, especially where several tenants depend on the same entrance and call system.
