Hotels and guesthouses: guest comfort and building security in one system
A small hotel or guesthouse faces the same tasks as a large hotel – room access, energy, kitchen, common areas, staff, night-time operation – just without a technical department or a night porter. A good system fills that gap: guests let themselves in even after midnight, empty rooms aren’t heated, the kitchen fridges are monitored overnight, the cameras cover the common areas lawfully, and in the morning an operator overview shows you what happened during the night.
Sound familiar?
- Someone has to stay up for late arrivals – otherwise the guest ends up phoning from outside the gate.
- The air conditioning runs all day with the balcony door open; by day two, the guest has beaten the key card switch with a business card.
- The programmer for the key card room locks has broken, and the manufacturer no longer supports it.
- The kitchen freezer defrosted over a weekend – and nobody noticed until Monday.
- There are solar panels on the roof, yet the water heaters heat up before dawn, the air conditioning peaks in the afternoon, and the solar output flows into the grid.
- More and more guests arrive by electric car, and booking sites already offer it as a search filter. But a charger would load the supply in the evening, together with the air conditioning and the laundry. And there’s no metering to put the charging on the room bill.
- The common-area cameras are old, the footage is useless, and there is no data protection documentation.
- Guests went up to the roof terrace at night, or to the closed pool – and you only found out afterwards.
- The staff use one key for everything, and the chef who left still has one.
Solutions
Room access: card, mobile key, code – and no more lost keys
The problem Metal keys get lost, there are no longer spare parts or support for the old card system, and the cleaner and the guest use the same key.
How do we solve it? Room locks that work with a card, a mobile key or a code, plus access control for the common areas, which can be linked to your property management software: the guest receives a card, mobile key or code valid for the length of the booking, which expires automatically at check-out; cleaning and maintenance staff get their own time-limited permissions, with every entry logged. Room statuses – occupied, vacant, to be cleaned – appear on the reception screen, connected to your hotel software if it supports this.
What you get No more lost keys or lock changes; guests let themselves in; the log shows you who has been in the room.
Self-service late arrival – with proper guest registration
The problem For an arrival after midnight you either have to keep a receptionist up or use a key box – and every previous guest knows its code.
How do we solve it? A video intercom and code-based access at the entrance: in the booking confirmation, the guest receives their own code, valid for that night, which opens both the entrance and their room. If there’s a problem, the call rings on your phone or the phone of whoever is on duty: you see the guest, can talk to them and then let them in remotely. Every entry is logged. We build the mandatory guest registration required in Hungary into the process, in coordination with your property management software.
What you get Night-time arrivals without staff, safely – and no guest phoning from outside the gate.
Energy: the room knows it’s empty
The problem A key card switch only detects whether there’s a card in the holder – if the guest gets round it, the air conditioning runs all day with the balcony door open. Empty rooms are kept at comfort temperature too.
How do we solve it? Each room gets occupancy and window-opening sensors: when the guest goes out, heating and cooling switch to economy; with a window open they stop; after check-out the room switches to away mode, and back to comfort before the next arrival. On a central screen you see the temperature and consumption of every room. Existing fan coils, air conditioners or radiators can be controlled without replacing them.
What you get Energy savings that can reach double-digit percentages – we estimate the likely amount during the site survey – without a guest ever arriving to a cold room.
Solar panels and battery storage: the building uses its own power
The problem Much of an accommodation’s consumption – hot water, air conditioning, kitchen, laundry, guests’ EV charging – could be scheduled, yet it runs whenever someone happens to think of it. As a result, the solar output goes into the grid, and peak-time electricity comes back at a high price; a battery on its own only partly solves this.
How do we solve it? Our solar partner builds or extends the solar system and the battery – a new system, a switch to a storage-ready inverter or an addition to an existing system – and we add energy management for the building: we measure generation and consumption and schedule the large consumers around generation and the tariff. Hot water cylinders heat up during the day from the solar output; pre-cooling of the rooms falls on the afternoon generation, and checked-out rooms switch to economy; guests’ EV chargers only get the available capacity, plus the surplus during the day; and the kitchen’s large appliances don’t all start at once. Generation, consumption and the status of the large consumers are shown in an easy-to-understand operator overview – with locally running control, independent of the inverter manufacturer.
What you get More of your own generation stays in the building, peak load flattens out, and guest charging doesn’t push up the building’s electricity bill.
Guest chargers in the car park: a booking argument, not a cost centre
The problem On accommodation booking sites, EV charging is now a search filter: anyone setting off in an electric car chooses from properties with a charger, and for longer stays this is decisive. Installing chargers, however, raises more questions than at a holiday home: several cars arrive at once, and they want to charge in the evening, just when everything is at peak; guests want a full battery by morning; staff and company cars park there too; and if someone charges and then leaves the car in the space until morning, the next guest can’t get to a charger. If you offer it free, the electricity bill goes up; if you want to charge for it separately, reception needs something to invoice from.
How do we solve it? We install several charging points on a shared supply, with dynamic load sharing: the chargers share the available capacity among themselves and together with the building’s consumption. For an overnight guest, the goal isn’t to charge in forty minutes – there are seven or eight hours available overnight, so four cars charging more slowly in parallel will typically still be full by morning – and the main fuse won’t trip because of charging. For longer stays, the system schedules charging around solar generation and the night tariff.
Billing follows hotel logic, not public charger logic: the guest starts charging with a code linked to their room number – or, with a compatible card system, their room card – and we add the consumption to the room bill, where it appears as a separate item at check-out. For this we install chargers with a certified (MID) meter, so the kWh figure can’t be disputed. Other options that also work: a free allowance included with a higher room category or package, with charging paid above it; a kWh package bought in advance at check-in; or a bookable charging space, where the system alerts you if someone keeps blocking the space after charging has finished. Staff and company cars charge with separate cards, to a separate cost centre.
If your car park can be reached from the street, the charger can also bring in revenue. Where the car park is open or freely usable during the day – a roadside guesthouse, a hotel that also runs a restaurant, a location on a busy main road or near a popular day-trip destination – the charging point can also be operated as a public one: we connect it to a charge point operator back-end system, and from there, through roaming, it also appears in the apps of e-mobility service providers (eMSPs). So it shows up on charging maps, and passing drivers can start and pay with their own charging app. Bank card payment can also be added to the charger. In this case, the system handles two modes at once: hotel guests charge with an ID linked to their room, from a discounted or free allowance, while outside drivers pay the market price. Public charging is subject to regulatory requirements; we go through these and the technical requirements – certified metering, the option of bank card payment, an outdoor, impact-resistant design, step-free access – during the site survey. We also tell you if, in your particular car park, it makes more sense as a guest-only charger.
What you get A search filter that keeps your property in the results on booking sites; charging that isn’t a problem for reception or for the main fuse; an item on the room bill instead of on the electricity bill – and, if the car park allows it, a charging point that also brings in revenue from non-residents while drawing them into your restaurant or café.
Common-area cameras – with usable images at night and managed access
The problem At night the old camera shows only blotches, the footage can’t be searched, guests haven’t been informed, and staff don’t know who is allowed to view the images. Meanwhile, there are a few places in the building where guests have no business being – the plant room, the boiler room, the roof terrace, the technical part of the underground garage, the kitchen and storeroom, the closed pool area in winter – and today these are protected at best by a sign and the watchful eye of the staff.
How do we solve it? Cameras on the entrance, the corridors, the car park, the storerooms and cash-handling points – never in guest rooms or inside the spa area. Person and vehicle detection, full-colour night images, local recording. We hand the system over with privacy masking and the necessary data protection documentation; we set the retention period on the recorder, and only designated people can access the footage, with every access logged.
Monitoring restricted areas – not following guests, but protecting places. The image analytics running in modern cameras don’t just see movement; they recognise whether a person has entered a marked zone. So an area can be marked out – the few square metres in front of the plant room door, the stairs leading to the roof terrace, the entrance to the kitchen and storeroom, the approach to technical rooms and the closed pool area. If someone walks in there – or appears at the spa entrance at night, after closing – reception is alerted immediately, and a polite voice announcement can play on site before anyone gets into trouble. The system watches zones: it doesn’t identify people or follow anyone around the building – no facial recognition, no guest profiling. An alert is a timestamp and a clip of a few seconds from the marked area, which is also named in the posted notice.
The main reason for this is not distrust, but safety and liability. In the plant room, near the boiler room and on the roof, guests – and especially children running around unsupervised – can be seriously hurt; the accident, however, becomes the property’s responsibility, and its insurer will ask what you did to prevent entry. The same logic helps in cases where nobody is hurt: using the pool after closing, drinks taken from the kitchen on a “just having a look” basis, or the roof terrace being discovered as a late-night party venue all show up in the same alert.
What you get Usable footage if there is damage or a complaint; an alert before a guest goes somewhere they could get hurt – and a system that alerts on zones, not one that identifies people.
Kitchen: fridges, freezers, gas and water monitored overnight too
The problem The cold room defrosts over the weekend, the freezer door is left open, water leaks under the sink – and all this only comes to light when it’s already too late.
How do we solve it? We fit a temperature sensor in every fridge and freezer, with a delayed threshold – a quick door opening doesn’t trigger an alert, a sustained deviation does – and notifications go to the chef and the manager. Water sensors at the sinks and in the plant room, with a motorised shut-off valve if required. The data is logged, so it also supports your HACCP documentation.
What you get Stock doesn’t defrost unnoticed – and you don’t have to throw out the weekend’s goods on Monday.
Smoking and noise in the room – flagged in time
The problem Someone smoked in a non-smoking room, the next guest complains, the room is out of use for a day – and there’s nothing to base a cleaning surcharge on.
How do we solve it? We fit air quality sensors in the rooms that detect the jump in particle and VOC levels typical of cigarette smoke and e-cigarette vapour (hairspray, deodorant or shower steam can also cause a false alert), along with a noise level meter that gives a decibel reading and does not record sound. The event is logged with a timestamp, and reception can respond immediately.
What you get A documented event that helps you enforce the house rules – not an argument after the fact at check-out.
Staff and suppliers: who, where, when
The problem One key opens everything, departing staff keep one, the supplier rings at six in the morning, the storeroom and the office are left open.
How do we solve it? Role-based access control: reception, kitchen, housekeeping, maintenance, management – everyone gets in where and when their work requires; suppliers get time-limited access to the service entrance. A departing employee’s permissions are removed with one click. The storeroom, the office and cash handling get a separate alarm zone that is armed outside working hours.
What you get No more “everyone’s key”; the log shows who opened the storeroom; and the protection of cash handling is documented.
Morning summary: what happened overnight
The problem In the morning nobody knows who arrived during the night, whether the back door was left open, whether anyone armed the alarm, or whether everything is fine in the kitchen.
How do we solve it? At handover we put together an operator overview that brings in the statuses and alerts from all the systems: entries and room statuses, alarm events, camera events, room temperatures, kitchen fridges, water, energy and chargers – plus a to-do list. The receptionist and the manager each get their own view and their own permissions, and important alerts also go to their phones. This view is built for your building, and we keep it up to date under the maintenance contract.
Two things deliberately stay in their own dedicated systems: the live camera view and recording management, and the certified billing of charging. For these, a dedicated, auditable interface is the right solution – because of logged access for video, and the billable metering chain for charging – so the overview links to them; it only shows the fact that an event occurred, not the image or the invoice itself.
What you get In three minutes each morning you know what happened overnight and what needs doing – without logging into four systems.
Guest Wi-Fi and the building network – kept separate
The problem Guests are on the same network as the reception computer, the cameras and the room locks – one infected laptop can reach the whole building.
How do we solve it? Guest Wi-Fi, the operator network, the cameras and access control each get their own network segment; guests only see the internet, and the systems aren’t visible from outside. We measure coverage and position the access points accordingly.
What you get Fast guest Wi-Fi – and a building whose security systems a guest’s laptop can’t reach.
Why MindzenSmart?
- We think as a system integrator. Access control, alarm, cameras, energy, network – built on one another and connected, not from five separate suppliers.
- A police-registered security systems company. MindzenSmart (Mindzen Direct Kft.) is a security systems company registered with the Hungarian police. We hand over alarm systems, cameras and access control with full documentation, and cameras with privacy masking and the necessary data protection documentation.
- A system sized to the building. From five rooms to sixty, the same principle, scaled to size and in phases if you like: we can start with access control, the cameras or whatever is most urgent.
Frequently asked questions
Is it worth it for a small guesthouse, or only for a large hotel?
With five to ten rooms, self-service late check-in and energy bring the most: you don’t need a receptionist overnight – we build the mandatory guest registration into the process – and rooms aren’t heated when empty. The system can be expanded room by room; there’s no need to fit out the whole building at once.
Can it be connected to booking or hotel software?
If a common interface exists, yes – we check this model by model: the guest code or mobile key is created from the booking, and check-out ends the permission. Where there’s no ready-made connection, we set up a simple reception procedure.
Can I get an alert if a guest heads into the plant room or onto the roof?
Yes: the camera sends an alert for a marked zone – plant room door, roof stairs, kitchen, storeroom, spa entrance after closing – when a person enters it. It watches zones: it doesn’t identify people and doesn’t follow anyone around the building. We hand it over with privacy masking and the necessary data protection documentation; we set the retention period on the recorder, only designated people can access the footage, with every access logged, and the monitored areas are marked with pictograms.
Will there be cameras or sensors in guest rooms too?
Cameras and sound recording, never. A room may have occupancy, window, temperature and air quality sensors, as well as a noise level meter that gives decibel readings – these measure conditions, they don’t watch people. This needs to be stated in one sentence in the house rules.
What do the insurer and inspectors get?
We build the alarm system from devices with a MABISZ recommendation (MABISZ is the Association of Hungarian Insurance Companies), matched to your insurance terms – with insurer compliance documented: during the site survey we go through the terms of your policy and put the system together to match. Cameras are handed over with privacy masking and the necessary data protection documentation; fridge monitoring supports your HACCP records. It doesn’t replace mandatory, certified measurement systems – it complements them.
Do you also install the solar panels and battery?
The solar system and the battery are installed by our solar partner, including the grid connection paperwork; we add energy management and the scheduling of the large consumers – hot water, air conditioning, kitchen, EV chargers – in the same system that also monitors the rooms and the kitchen. It can also be added to an existing solar system later, even without replacing the inverter.
How is a guest’s EV charging billed?
Following hotel logic: the guest starts charging with a code linked to their room number – or, with a compatible card system, their room card – and we add the consumption to the room bill, where it appears as a separate item at check-out. For this we use chargers with a certified (MID) meter, so the kWh figure can’t be disputed. A free allowance with paid charging above it, a kWh package bought in advance and bookable charging spaces also work; staff and company cars charge with separate cards, to a separate cost centre.
Can a public charging point be operated in the car park?
If the car park can be reached from the street, yes: the charging point can be connected to a charge point operator back-end system, and from there, through roaming, it also appears in the apps of e-mobility service providers. So it shows up on charging maps, and non-resident drivers can start and pay with the app they already use. Hotel guests, meanwhile, can charge from a discounted or free allowance. We go through the regulatory requirements for public charging during the site survey, and also tell you whether it’s realistic at your location, or whether it’s better run as a guest-only charger.
Will everything be in one app?
Not in one app, but in one overview: the statuses and alerts from the systems – access, alarm, temperatures, water, energy, chargers – come together in one place, with role-based views for reception and the manager. The live camera view and recording management, and the certified billing of charging, stay on their own auditable interfaces, because that’s where logged video access and billable metering belong – the overview links to them. We put this view together for your building at handover.
Can existing key card room locks be kept?
If they use a standard reader and controller, often yes; if the manufacturer no longer supports them, we replace them in stages, room by room, while you stay open.
Can it be installed while we’re operating?
Yes: room by room, corridor by corridor, around your occupancy; we schedule kitchen and plant room work for after closing.
