The Client
Macchina Security DOO is one of Serbia's leading security and systems integrators, founded in 1994 and headquartered in Novi Beograd — Belgrade's modern commercial district. With 46+ employees, the company designs and deploys integrated security solutions across video surveillance, fire protection, alarm systems, and access control. Macchina Security has also developed a Safe City portfolio — an integrated suite of urban security and mobility solutions that now includes smart parking — aligning the company with Serbia's broader smart-city modernisation priorities. It serves both domestic Serbian clients and regional markets across the Western Balkans, positioning itself as a natural channel partner for international IoT vendors entering the Serbian market.
Fleximodo's relationship with Macchina Security is, in miniature, a case study in how a single well-positioned integrator can take a vendor from zero presence in a country to an active, multi-city, multi-category commercial relationship in under three months. What began as a single full-stack hardware order for one Belgrade district grew, within 75 days, into a five-order relationship spanning hardware, a multi-city software platform, professional configuration services, and bespoke software development.
November 2024: The First Serbian Deployment — LoRaWAN Sensors and Digital Parking Signage in Novi Beograd
On 14 November 2024, Macchina Security placed Fleximodo's first-ever Serbian order: a full-stack deployment for Novi Beograd combining an in-ground LoRaWAN parking sensor fleet, 3-digit digital parking guidance signage, a one-year IoT Hub licence, and installation equipment. This was Macchina Security's first parking-specific IoT procurement and, simultaneously, Fleximodo's first deployment anywhere in Serbia — opening the country as a new national market.
Novi Beograd is Belgrade's primary commercial district, home to corporate headquarters, government agencies, a convention centre, and shopping centres that attract heavy daily vehicle traffic. Parking demand regularly exceeds supply there, producing the kind of congestion and curb-side chaos that frustrates drivers and municipal authorities alike. Any deployment in this district needed to deliver visible value immediately: drivers needed clear guidance to open spaces, and operators needed reliable, real-time occupancy data from the underlying in-ground parking sensors.
The order's full-stack composition was commercially decisive for Macchina Security. Rather than buying isolated sensors, the company acquired a complete parking guidance system: smart parking sensors detect occupancy using Fleximodo's dual detection technology (a 3-axis magnetometer combined with nanoradar), the 3-digit outdoor digital parking signage displays live space counts to approaching drivers, and the IoT Hub handles backend data processing, API delivery, and monitoring. Every component was visible and operational from day one — giving Macchina Security a reference installation it could use to sell similar deployments to other Serbian municipalities and commercial operators. The 3-digit display specification (100–999 total spaces) matched the scale of a Novi Beograd commercial car park, shopping centre, or office-tower basement, and its traffic-sign frame was built to comply with Serbian and EU road signage standards for legal public-facing operation.
This first order also mattered strategically for Fleximodo. Serbia's smart-city segment had historically lagged behind Central European neighbours due to budget constraints and procurement complexity, but recent years brought acceleration driven by EU accession processes, international development funding, and corporate real-estate investment in Belgrade's modern districts. Entering that market through a 46-employee integrator with an existing Safe City portfolio — rather than through a small distributor — gave Fleximodo a partner able to cross-sell parking guidance into every existing client relationship: a bank whose branches already used Macchina Security's access control could now also buy parking signage; a shopping centre already using its fire-alarm monitoring could now add outdoor beacons and occupancy sensors, all under one procurement contract.
January 2025: Multi-City CityPortal Expansion — Zaječar and Užice
What followed surprised even seasoned Fleximodo partner-watchers. Just 62 days after the first order, on 15 January 2025, Macchina Security placed two further orders on the same day — its second and third — activating CityPortal, Fleximodo's driver-facing navigation and municipal reporting platform, in two entirely different Serbian cities: Zaječar and Užice.
Order 2 — Zaječar. Zaječar is a regional administrative centre of roughly 45,000 residents in eastern Serbia, near the Bulgarian border, with a university, a hospital, and historically significant Roman archaeological sites. It shares the smart-city modernisation pressures of larger cities but with much smaller municipal budgets — exactly the profile where a centralised SaaS platform like CityPortal delivers disproportionate value, giving the city enterprise-grade smart parking capability without having to build local infrastructure or hire specialist operators. The order activated a city-specific CityPortal instance under an annual OPEX per sensor billing model, prepaid a year in advance — a scale appropriate to a modest initial sensor fleet, likely a pilot around a high-demand location such as the hospital, city centre, or main commercial street.
Order 3 — Užice. Placed the same day, this order activated CityPortal in Užice, a city of roughly 60,000 residents in western Serbia, seated in the Đetinja river valley and serving as the administrative centre of the Zlatibor District. Užice's parking demand swings sharply between weekdays and weekends and across tourist seasons (the Zlatibor mountain resort lies just south of the city), which is exactly the kind of variable-demand scenario where data-driven parking occupancy detection outperforms static approaches. The Užice order was noticeably larger than the paired Zaječar order, suggesting a bigger underlying sensor fleet targeting multiple high-demand locations — the main shopping district, municipal buildings, hospital parking, and commuter lots near industrial zones.
Together, these two same-day orders reveal a company operating well ahead of a typical integrator rollout cadence. Most Fleximodo partners pilot in one city, validate for six to twelve months, and then expand; Macchina Security compressed that cycle to weeks, closing deals in Zaječar and Užice before the Novi Beograd reference installation had even had time to accumulate a long operating history. This was made possible by CityPortal's architecture: each city runs as an independent instance with its own data isolation, branding, municipal dashboard (accessed through a dedicated CityPortal login), and OPEX billing, so cities can be activated in parallel without entangling one another. It also demonstrated that CityPortal functions as a standalone commercial product — the platform does not require Fleximodo sensors underneath it, and can process data from other compatible sensor hardware, which matters for cities that already have infrastructure in place.
Within 62 days of its first order, Macchina Security had gone from a single-city pilot to an active three-city rollout — Novi Beograd, Zaječar, and Užice — spanning three distinct Serbian regions.
January 2025: From Rollout to Real Operations — Service and Software Follow-Through
Twelve days later, on 28 January 2025, Macchina Security placed its fourth and fifth orders — again on the same day — and this time the story shifted from expansion to operational maturity.
Order 4 — Signage and carpark reconfiguration (4 man-days). The order description was unusually specific: Macchina Security needed to dismount most of 8 old carparks and create approximately 26 new carparks across 2 cities, with fresh sensor allocation and new connections running from the sensors and carparks through every system level up to the displays — over 20 displays, some showing 3-5 carparks each, involving what the order itself called "many mathematical variations." All of it totalled roughly 4 man-days of dedicated Fleximodo configuration work.
This is the clearest window yet into the real scale of Macchina Security's Serbian footprint. Smart parking deployments rarely match their original specification once they have been running for a few months: real-world usage reveals which carparks sit in the wrong place, which displays show the wrong information, and which sensor-to-display mappings need adjusting to keep driver guidance accurate. Reconfiguring at this scale — more carparks than existed originally, spread across two cities, feeding more than 20 outdoor beacons and digital signage units — only happens when a deployment is genuinely live and being used by drivers every day. Businesses do not commission four days of expert reconfiguration work for infrastructure sitting idle.
Order 5 — CityPortal software change request. Placed the same day, this order funded something more fundamental than configuration: a change to CityPortal's own logic. The platform's default model aggregates sensor availability at the carpark level — a display shows availability for the carpark it belongs to. That works for simple, single-carpark-per-display topologies, but Macchina Security's infrastructure, with 20+ displays and sometimes 3-5 carparks connected to a single display, needed finer control: the ability to assign individual sensors, or arbitrary sensor groups, to individual displays, cutting across carpark boundaries where necessary. Real scenarios driving this need include shared driveways serving two adjacent carparks where a display should only reflect the sensors nearest the entrance, priority-parking displays near a hospital that should show only accessible spaces, directional guidance where a display should reflect only the sensors reachable from one side of a street, and temporary event configurations that require dynamic sensor grouping.
The two orders are companions in the truest sense: the software change request delivered the new sensor-to-display assignment capability, and the reconfiguration service then rebuilt the live deployment to use it — identify the limitation, fund the platform change, then re-point the infrastructure at the new capability. That is the workflow of a mature, ongoing customer-vendor partnership, not a first-time pilot evaluation. It also means the new logic became a permanent CityPortal capability, benefiting every future Fleximodo customer who logs in through CityPortal, not just Macchina Security.
Why Macchina Security Kept Ordering
Across five orders and four distinct procurement categories — hardware, platform subscription, professional services, and bespoke software — in just 75 days, a consistent pattern emerges. Macchina Security did not treat its first Fleximodo order as a one-off pilot to be evaluated cautiously over a year; it pre-sold CityPortal into two additional cities before the reference Novi Beograd installation had a long track record, then funded real operational support and platform customisation the moment its live deployment outgrew the platform's defaults. Each step signalled increasing commitment rather than caution: more cities, more carparks, more displays, and eventually direct investment in shaping the CityPortal product itself. A customer planning to switch vendors does not fund improvements to the vendor's core platform — Macchina Security did, which is as clear a signal of long-term partnership as a repeat order itself.

Novi Beograd's climate swings from sub-zero winters to hot summers, and this is exactly where automatic temperature compensation matters for a magnetometer parking sensor. Heat and cold alter a magnetometer's baseline magnetic-field readings, and without correction that drift can produce false occupancy readings. Fleximodo's in-ground sensors continuously recalibrate for temperature, which is how the 99.96% detection accuracy figure holds across the full -40 to +85 °C operating range rather than only under lab conditions — a detail that matters just as much in Zaječar's continental winters and Užice's mountain-adjacent climate as it does in Belgrade.

Frequently Asked Questions
Is this Fleximodo's first deployment in Serbia? Yes. Macchina Security's 14 November 2024 order was the first Fleximodo smart parking deployment in Serbia, opening a new national market. The country's smart-city segment has accelerated in recent years, driven by EU accession processes, international development funding, and corporate real-estate investment in Belgrade's modern districts.
What is Macchina Security's Safe City portfolio? Safe City is Macchina Security's integrated urban security and mobility solution suite, combining video surveillance, access control, fire protection, alarm systems, and now IoT parking guidance. The portfolio approach lets banks, shopping centres, corporate campuses, and government facilities buy multiple solutions through a single integrator, with unified support and procurement.
Why is a 3-digit guidance display specified for Novi Beograd? The 3-digit format indicates a facility with 100–999 total parking spaces — appropriate for a Novi Beograd commercial car park, shopping centre, or office tower. The traffic-sign frame ensures compliance with Serbian and EU road signage standards, which is critical for legal operation in public-facing digital parking signage installations.
Why did Macchina Security expand into Zaječar and Užice so quickly after the first order? Just 62 days after its first Serbian order, Macchina Security placed CityPortal OPEX orders for two additional cities on the same day. This indicates the company was pre-selling deployments before the Novi Beograd reference installation had accumulated a long operating history — an aggressive cadence reflecting the urgency of Serbian smart-city procurement, where EU accession milestones and development funding create time-bound windows that reward fast-moving integrators.
What does CityPortal OPEX cover, and does it require Fleximodo sensors? CityPortal OPEX is an annual per-sensor subscription for Fleximodo's driver-facing navigation and municipal-reporting platform. Drivers see available spaces through a web/mobile interface; municipal operators see occupancy trends, enforcement statistics, and revenue reporting through a dedicated CityPortal login. Each city instance is independent — separate data, branding, and billing — and CityPortal can operate as a standalone product, integrating sensor data from Fleximodo hardware or from other compatible sources.
Why does a smart parking deployment need reconfiguration a couple of months after launch? Real-world operation reveals which carparks sit in the wrong location, which displays show the wrong information, and which sensor-to-display mappings need adjustment. Macchina Security's first 75 days of operation required dismounting 8 original carparks and creating roughly 26 new ones across 2 cities, with full sensor-to-display reconnection across 20+ displays — standard operational evolution for an actively used deployment at growing scale.
Why did Macchina Security fund a CityPortal software change request instead of working around the limitation? CityPortal's default logic aggregates sensor availability at the carpark level, which is not granular enough when 20+ displays sometimes show 3-5 carparks each. Macchina Security needed the ability to assign individual sensors or sensor groups to individual displays — for shared driveways, priority parking near sensitive locations, directional guidance, and temporary event configurations. Funding a platform-level change was commercially cleaner than carrying the limitation forward as permanent technical debt, and the resulting capability became a standard CityPortal feature available to future customers as well.
What is automatic temperature compensation in a parking sensor? Automatic temperature compensation is a calibration process that continuously adjusts a magnetometer parking sensor's readings to offset the effect of temperature on its magnetic-field baseline. Without it, heat and cold can cause the baseline to drift, producing false vacant/occupied readings. Fleximodo's in-ground LoRaWAN parking sensors apply this compensation automatically, which is how they maintain 99.96% detection accuracy across a -40 to +85 °C operating range — relevant across Novi Beograd, Zaječar, and Užice's varied climates.
Why did Macchina Security Serbia keep ordering from Fleximodo? Across five orders in 75 days, Macchina Security moved through every major Fleximodo procurement category: hardware, platform subscription, professional services, and bespoke software development. Rather than waiting to validate one city before expanding, it pre-sold CityPortal into two additional cities within 62 days of its first order, then funded real operational support and platform customisation the moment its live, growing deployment outgrew the platform's defaults. Investing directly in shaping CityPortal's product logic — rather than working around its limits or switching vendors — is a strong signal that Macchina Security views Fleximodo as its long-term smart-parking platform partner for the Serbian market.
