A Better Way to Handle Guests Than the Intercom
Summary: The traditional buzzer and intercom system is inconvenient, insecure and offers no record. This article looks at how app-based visitor management improves how apartment buildings handle guests.
The buzzer and intercom is the traditional way apartment buildings handle visitors, and it is so familiar that most people never question it. A visitor arrives at the entrance, presses the button for the apartment they are visiting, a resident answers and buzzes them in. It seems simple and adequate. But the buzzer system has real weaknesses that become obvious once examined, and for a building that wants to be well run and secure, the humble intercom is a surprisingly poor tool that better technology can now replace.
Consider the inconvenience first. The buzzer requires the resident to be at home and available to answer at the moment the visitor arrives. If the resident is out, expecting a delivery, the delivery cannot get in. If they are in the shower or on a call, the visitor waits. If the resident wants to let in a guest who is arriving before they get home, they cannot. The buzzer ties visitor entry to the resident’s physical presence at the intercom in real time, which is often inconvenient and sometimes impossible. Modern life does not fit neatly around being available to press a button when someone happens to arrive.
Then consider security. The buzzer offers very little. A resident buzzing someone in is taking it on trust that the person at the door is who they say they are, often based on nothing more than a voice through a crackly speaker. There is no record of who was buzzed in, by whom or when. If something goes wrong, the building has no information about who entered. The buzzer grants access but captures nothing, which means it provides entry without providing any of the accountability that real security requires. It is a door opener, not a security system, though it is often treated as the latter.
There is also the problem of shared and tailgated entry, which the buzzer does nothing to address. Once the door is buzzed open, anyone can enter, not just the intended visitor. People hold doors for strangers, and unauthorised individuals follow legitimate visitors in. The buzzer has no way of knowing or recording any of this. It opens the door and is blind to who actually walks through it, which is a fundamental limitation of a system that controls a moment of opening rather than managing access as an ongoing, recorded process.
Aregnum offers apartment buildings a better way to handle visitors through app-based visitor management. Rather than relying on real-time presence at an intercom, a resident can pre-authorise an expected visitor in advance. The visitor is then recognised on arrival and can gain entry without the resident needing to be at the intercom at that exact moment. A resident expecting a delivery while at work can authorise it ahead of time. A guest arriving before their host gets home can be let in. The entry is decoupled from the resident’s real-time availability, which removes the central inconvenience of the buzzer.
Crucially, app-based visitor management captures a record where the buzzer captures nothing. Each pre-authorised visit is tied to the resident who authorised it and recorded, so the building knows who entered, for whom and when. This transforms visitor entry from an unaccountable moment of door-opening into a recorded event with a responsible party behind it. If a question arises about who was in the building, there is an answer, which is something the buzzer can never provide.
The accountability this provides is valuable for the building as a whole, not just for individual residents. A building where visitor entry is recorded is a building where management and the body corporate have visibility of visitor activity, which supports security and helps resolve disputes. A building running on buzzers is blind to its own visitor activity, which means it can neither demonstrate nor improve its security in any evidence-based way. Moving to recorded visitor management gives the building a foundation for actually managing its security rather than just hoping the buzzer is enough.
For residents, the app-based approach is simply more convenient and gives them more control. They manage their own visitors on their own terms, authorising expected guests, deliveries and contractors in advance, rather than being tethered to the intercom. This fits how people actually live, with busy schedules and visitors who do not always arrive at convenient moments. The resident is in control of their visitor flow in a way the buzzer never allowed, which is a meaningful improvement in daily living.
It is worth acknowledging that not every visitor is pre-authorised, and a good system has to handle the unexpected arrival as well. The point is not that pre-authorisation replaces all judgement, but that it handles the large proportion of visits that are expected smoothly and with a record, while unexpected arrivals can still be dealt with appropriately. The buzzer treats every visit as an unexpected real-time event requiring the resident’s immediate presence, which is the wrong default when most visits are actually expected.
The dependence on real-time presence is the buzzer’s most fundamental limitation, because it assumes a model of life that no longer holds. The buzzer was designed for a time when someone was more likely to be home to answer it, but modern residents work, travel, and lead lives that frequently leave them away or unavailable when a visitor or delivery arrives. The buzzer’s requirement that the resident be present at the intercom at the exact moment of arrival is increasingly out of step with how people actually live, which is why deliveries are missed and visitors are left waiting. Pre-authorisation fixes this not by improving the buzzer but by removing its core assumption, decoupling entry from the resident’s real-time presence so that life does not have to revolve around being available to press a button.
The security weakness of the buzzer is more serious than its inconvenience, and it is worth being precise about why. When a resident buzzes someone in, they are making a security decision based on minimal information, often just a voice claiming to be someone, and granting access to the whole building, not just their own apartment, on that basis. The person admitted can then move through common areas and reach other apartments. So one resident’s casual decision to buzz in an unverified caller affects the security of every other resident in the building. This shared exposure, where any resident can compromise the building’s security with a single careless buzz, is a structural weakness of the buzzer that no amount of resident vigilance fully resolves, because it only takes one lapse.
The absence of any record is what makes the buzzer useless for the building as a whole, as opposed to individual residents, and this is the dimension bodies corporate should care about most. A building has a collective interest in knowing who enters it, for security, for resolving disputes, and for demonstrating that access is controlled. The buzzer serves none of this collective interest because it records nothing; each buzz is an unrecorded event that vanishes the moment the door closes. The building is therefore blind to its own visitor activity, unable to investigate incidents, resolve disputes about who was let in, or show that it manages access responsibly. Replacing the buzzer with recorded, app-based visitor management gives the building the collective visibility that the buzzer structurally cannot provide.
It is fair to note that the buzzer’s simplicity has genuine appeal, and a replacement must not sacrifice too much convenience to be accepted, which is why the app-based approach has to be genuinely easy. The buzzer is instantly understood and requires nothing of the visitor beyond pressing a button. An app-based system earns its place by being convenient in a different and ultimately more flexible way: residents authorise expected visitors easily and in advance, on their own schedule, and the large majority of visits are expected. The system handles the predictable visits smoothly while still dealing with the genuinely unexpected arrival appropriately. The aim is not to make visitor entry more complicated than the buzzer but to make it work for the way people actually live, with the added benefit of a record the buzzer never kept.
The buzzer represents a whole category of familiar tools that persist not because they work well but because they are entrenched and unquestioned, and questioning them is how a building improves. Replacing the buzzer with app-based visitor management is a concrete example of choosing a tool that fits how people actually live and what a building actually needs, over one that merely happens to be what was always there. Buildings that are willing to question their entrenched tools, the buzzer among them, are the ones that steadily become better places to live.
The buzzer and intercom served apartment buildings for decades, but it was always a limited tool: inconvenient because it demands real-time presence, insecure because it captures nothing, and blind to who actually enters. Aregnum’s app-based visitor management replaces it with something that fits modern life and modern security expectations, letting residents authorise visitors in advance and giving the building a proper record of who came and went. For apartment buildings still relying on the buzzer, the improvement in both convenience and security is substantial.
Frequently Asked Questions
What is wrong with the traditional buzzer system?
The buzzer requires the resident to be present at the intercom to answer in real time, offers very little security since entry is granted on trust with no verification, and captures no record of who was let in, by whom or when.
How does app-based visitor management work instead?
A resident pre-authorises an expected visitor in advance, so the visitor is recognised on arrival and can gain entry without the resident needing to be at the intercom at that moment. The visit is tied to the authorising resident and recorded.
Can I let in a delivery while I am at work?
Yes. Because entry is decoupled from your real-time presence at the intercom, you can authorise an expected delivery or visitor ahead of time and they can gain entry while you are out, with the entry still recorded.
Does the building get a record of visitors?
Yes. Each pre-authorised visit is recorded and tied to the resident who authorised it, giving the building visibility of visitor activity that the buzzer never provided, which supports security and helps resolve disputes.
