Apartment Intercom Systems: Planning Entrances, Apartments and Mobile Answering

Planning an apartment intercom system involves considerably more than choosing a door station. A multi-unit building may have a main lobby, secondary entrances, a car park, deliveries, individual apartment monitors and residents who expect to answer visitors from their smartphones. The equipment must work together, but so must the cabling, access permissions and ongoing building management.

For New Zealand installers, developers and body corporates, BPT and Akuvox offer different approaches. BPT offers modular entrance stations and compatible residential monitors, while Akuvox provides SIP-based and two-wire options alongside its SmartPlus mobile-answering platform. This guide explains how to plan entrances, apartments and mobile answering before committing to a system.

1. Map every entrance before choosing equipment

Start with a door schedule that identifies every location where residents, visitors or contractors need access. A typical development may have a main pedestrian entrance, secondary lobby, underground car park and delivery entrance. Some locations require a video intercom, while others may need only an authorised credential reader or keypad.

Record which apartments each entrance must call, whether visitors need a searchable directory, which door or gate must be released and who will manage credentials. Confirm whether the building has a reception desk or caretaker who needs to receive unanswered calls.

For example, a 24-apartment building might use a video entrance panel in the main lobby, credential-only access at the car park and a separate service-door arrangement for deliveries. Residents may have an indoor monitor, mobile answering or both. The best equipment schedule follows these requirements rather than treating every entrance identically.

2. BPT: Modular apartment entrances and indoor answering

BPT MTM entrance panels

The BPT MTM range offers a modular approach to entrance stations. Installers can select suitable modules and calling arrangements for the building, subject to the specific system architecture and supported combinations. This is useful where a development needs a tailored entrance panel rather than a fixed-format station.

For smaller buildings, dedicated call buttons can provide familiar visitor operation. Larger apartment blocks may benefit from a digital directory, depending on compatible modules and the selected BPT platform. Confirm the available panel space, mounting method, weather exposure, vandal-resistance requirements and lighting before finalising the entrance design.

BPT XTS WiFi indoor monitor

The BPT XTS 7-inch WiFi monitor gives residents a dedicated indoor answering point. In supported configurations, its WiFi functionality also supports mobile-connected use. Check the exact entrance system, network requirements and manufacturer-supported app functions before promising smartphone answering across all BPT installations.

A fixed indoor monitor can be especially useful in apartments shared by multiple residents, in buildings where occupants may not own compatible smartphones, or where a property manager wants a conventional answering method. It also reduces reliance on residents keeping a mobile app configured, although the entire system must still be tested for its actual failure behaviour.

3. Akuvox: Two-wire retrofits, SIP intercoms and mobile access

Akuvox R20K-2 for suitable two-wire installations

The Akuvox R20K-2 combines video intercom functions with a keypad and RF card reader in a compact, two-wire SIP door station. It can suit retrofit planning where existing cabling may be reusable with the appropriate Akuvox two-wire network equipment. A legacy cable pair is not automatically suitable: assess conductor condition, distance, layout and manufacturer specifications first.

For a new development with structured cabling, compare Akuvox's compatible Ethernet-based SIP range as well. Make the architecture decision early because the selected platform affects switching, power, addressing, call routing and potential cloud-service requirements.

Akuvox S562 indoor monitors

The Akuvox S562 is a 7-inch Linux-based SIP indoor monitor for compatible Akuvox installations. Wired and WiFi-capable variants are separate products, so specify the exact model rather than assuming every S562 supports wireless connectivity. Plan each apartment's monitor location, network route and power arrangement at the design stage.

4. Plan mobile answering as a building service

Mobile answering allows an authorised resident to receive supported intercom calls when away from home, see visitors where video is enabled and release an appropriate entrance remotely. It is valuable for deliveries and households with varied schedules, but the experience depends on internet connectivity, correct account setup, device permissions and ongoing service availability.

Akuvox SmartPlus

A compatible Akuvox SmartPlus installation can provide smartphone visitor answering and supported resident-management features. Confirm the number of users required per apartment, the precise device and feature compatibility, any applicable subscriptions and who will administer the property. Do not assume every Akuvox door station offers identical cloud functions. Refer to the official Akuvox SmartPlus community installer guide when planning buildings, apartment assignments, resident accounts and relay permissions.

BPT mobile answering

For BPT, select a supported mobile-enabled configuration, such as the appropriate XTS WiFi installation, and confirm its required services and network arrangements. BPT's mobile ecosystem and Akuvox SmartPlus are separate solutions, not interchangeable applications.

During commissioning, test a call from each entrance to the correct apartment, including the indoor station and every authorised smartphone intended to ring. Check how unanswered calls behave, whether multiple residents can answer and whether the release function is restricted to the correct entrance.

5. Compare BPT and Akuvox against the building requirements

Planning area	BPT	Akuvox
Entrance design	Modular MTM configurations and other compatible door stations	Compact SIP and selected two-wire stations, including R20K-2
Indoor answering	Compatible monitors including XTS WiFi	Compatible SIP monitors including S562
Mobile answering	Selected supported BPT monitor and service configurations	Compatible SmartPlus-enabled installations
Retrofit considerations	Existing BPT infrastructure and platform compatibility	Dedicated two-wire solutions, subject to cable assessment
Management	Depends on the installed BPT architecture	Depends on Akuvox hardware and configured SmartPlus services

Neither brand should be specified solely on the strength of a mobile-app demonstration. The practical decision depends on apartment count, wiring, entrance layout, access requirements, resident expectations and the availability of ongoing technical administration.

6. Design cabling, power and network capacity

Prepare a cable schedule for every door station, indoor monitor, interface, controller and power supply. On an existing site, test the cabling before committing to a two-wire upgrade. On a new IP installation, budget for switching capacity, network segregation, power requirements and appropriate connectivity between buildings and risers.

Determine which equipment relies on building internet and which functions remain available locally. A mobile app generally needs external connectivity, but behaviour during an outage varies by platform and configuration. Consider suitable backup power for building-critical equipment and confirm the expected operation of door release, resident calling and access credentials during power or network failures.

Document who owns the intercom network, who can change its settings and which contractor is responsible for firmware updates. A technically capable installation can become difficult to maintain if network and administrator credentials are not handed over correctly.

Network and resilience checklist

• Confirm the supported network topology, power supplies, switch capacity and any platform-specific gateways before ordering equipment.
• Allocate addressing and network access for each panel, apartment monitor and management device; document any necessary outbound cloud connectivity.
• Agree on the expected behaviour when building internet, mobile data, a network switch or mains power fails, and test recovery after service returns.
• Separate resident administration from installer-level system configuration and record the authorised handover procedure.

7. Integrate door release and access control safely

Intercom communication and door hardware are related but separate parts of the design. For each opening, confirm the type and voltage of electric locking hardware, release interfaces, exit hardware and any separate access-control controller. Establish how residents access the building without calling their own apartments and how contractors receive temporary or managed access.

Door release must comply with the applicable building and emergency-egress design. Coordinate with the project's fire and electrical specialists where required. Do not assume an intercom relay by itself addresses emergency-release, life-safety or credential-management requirements.

8. Plan privacy and resident turnover

A building manager needs a straightforward way to change apartment assignments when residents move. Establish who can add or remove mobile accounts, update a calling directory and revoke credentials. An outgoing resident's smartphone access should be removed promptly rather than relying on the resident to uninstall an app.

Agree on access to any retained video, images or call logs, and document retention settings where supported. Limit administrator privileges, change default passwords and establish an equipment-maintenance schedule. Where cloud services are involved, understand the provider's service terms and the building's responsibilities under applicable New Zealand privacy requirements. Where an intercom installation captures or stores identifiable visitor footage, assess the collection purpose, appropriate notice, authorised access, security and retention. The New Zealand Privacy Commissioner's CCTV guidance provides useful principles for installations that record personal information; determine how they apply to the proposed intercom system.

9. Commission every entrance and apartment

Commission the entire building, not only the demonstration apartment. Test directory entries, monitor ringing, audio and video quality, mobile answering, release permissions and resident credentials at every entrance. Test multiple simultaneous users where the equipment and project requirements call for it.

• Confirm every apartment receives calls from its authorised entrances.
• Test the correct indoor monitor and configured mobile devices.
• Verify release operates only the intended door or gate.
• Check access credentials, keypad permissions and administration roles.
• Document behaviour during internet or power loss and restoration.
• Provide the building manager with support contacts, configuration records and account-handover procedures.

Make the final handover part of the specification. Resident account administration and practical troubleshooting will matter long after the installer has left the site.

Frequently asked questions

Can apartment residents answer an intercom when away from home?

Yes, with a compatible mobile-enabled installation and correctly configured smartphone accounts. Functions depend on the exact hardware, connectivity and any applicable service plan.

Can old apartment intercom cables be reused?

Potentially, with a suitable two-wire platform such as the relevant Akuvox equipment. Existing cable condition, routing, distances and manufacturer requirements must be assessed first.

Does every apartment need an indoor monitor?

Not necessarily. Some compatible systems support mobile-first use, but a fixed monitor gives residents a dedicated answering point and should be considered against the building's reliability and usability requirements.

Can one system cover several entrances?

Compatible multi-entrance configurations can, provided the platform supports the required devices, routing and release permissions. Include every entrance in the initial equipment schedule.

What happens when a tenant moves out?

The authorised administrator should revoke their mobile account and credentials, update apartment records and provision the incoming resident. The handover process should be documented before occupancy.
