The Client

GAZZETA Group s.r.o. is a Prague-based event marketing and exhibition services company founded in 1995, headquartered at Libčanská 938 in Prague 9. With 6–9 employees, GAZZETA specialises in trade fair booth design, exhibition builds, and event marketing solutions integrating traditional build techniques with emerging technologies including 3D immersive displays and light shows. The company is a member of the Czech Exhibition Firms Association (AVFCR), placing it within the professional community of Czech trade fair and exhibition specialists.

This first Fleximodo order is intriguing precisely because GAZZETA is not a typical parking sensor client. The company's core business is event marketing, not traffic infrastructure — meaning this deployment serves a specialist application rather than a standard municipal or commercial parking installation. The choice of Sensor Standard XL with E-Permit Card suggests a specific use case: vehicle detection and identification at an event venue, exhibition ground, or VIP parking zone where standard permit enforcement alone would be insufficient.

The Challenge: Vehicle Identification at Specialist Event Venues

Event marketing companies face unique parking challenges that conventional municipal sensors do not address. Trade fair venues host rotating exhibitors, sponsors, and VIPs who require dedicated parking with automatic identification. Exhibition grounds need temporary but reliable parking occupancy detection that can be installed without permanent road modifications. Sponsor activation zones require permit-based access control that enforces both occupancy and identity — the kind of parking enforcement software layer that pure sensor detection alone cannot deliver.

A specialist deployment combining Sensor XL (the larger outdoor variant designed for open-area detection, and an NB-IoT parking sensor at its core) with E-Permit Cards (BLE-based vehicle identification) addresses all three challenges simultaneously. Sensors detect whether spaces are occupied; Permit Cards identify which vehicles belong in which spaces. Combined with flexible monthly OPEX billing per sensor/card, the deployment provides flexible, scalable coverage suited to temporary or rotating event configurations.

The Solution: Sensor XL with Surface Adaptor, E-Permit Card, and Monthly OPEX

The deployment included:

• IoT Parking Sensor Standard XL (Outdoor) with Surface Adaptor (NB-IoT) — The larger Sensor XL variant for outdoor detection, mounted on a surface adaptor rather than cored into the ground (likely reflecting the temporary or heritage-surface nature of the installation)
• E-Permit Card (OPTIONAL) for vehicle identification — BLE-based permit enforcement linking specific vehicles to specific spaces, feeding occupancy and identity data back into Fleximodo's CityPortal management platform
• Monthly SW/App & connectivity OPEX per sensor and per e-permit card — Pay-as-you-go backend and connectivity, suited for deployments where upfront lifetime OPEX commitments are impractical

The choice of surface adaptor instead of core-drilled installation is particularly telling. Unlike in-ground parking sensors that require permanent core-drilling into the pavement, GAZZETA's deployment is likely on a surface where road cutting is not possible or not desired — an exhibition hall forecourt, a heritage venue, a leased event space, or a surface that must return to its original state after the installation period. The surface adaptor provides full Sensor XL functionality without structural modification to the underlying pavement, while still relying on the same magnetometer parking sensor and radar dual detection technology used in Fleximodo's core-mounted units.

The monthly OPEX model is a deliberate departure from Fleximodo's typical lifetime or annual billing structures. Monthly billing lowers the entry barrier for clients who cannot commit to 1-year or lifetime OPEX upfront — particularly specialist applications where the deployment's duration is uncertain, where budget must be charged to specific events rather than capitalised, or where the total sensor count is too small to justify enterprise commercial negotiations.

Why This Order Matters: The Small-Scale Specialist Segment

GAZZETA's deployment represents a commercial segment that is often overlooked in enterprise IoT case studies: the small-scale specialist client. With an estimated 3–5 sensors plus permit cards, this is not a strategically significant order by revenue — but it demonstrates that Fleximodo's product architecture supports deployments at any scale, from single-digit sensor counts to thousand-unit fleets.

The importance is operational, not commercial. Each small-scale deployment teaches something about sensor flexibility:

• Sensor XL with surface adaptor works outside of core municipal parking contexts — validating the hardware for event-marketing, exhibition, and temporary venue applications
• Monthly OPEX enables specialist deployments — removing the commercial barrier for clients whose budget cycles do not align with annual commitments
• E-Permit Card integration works at tiny scale — not just at enterprise deployments like Cacttus's 500-unit order

For Fleximodo's broader market position, these small orders validate that the technology scales downward as well as upward. A product architecture that supports large enterprise rollouts like Project Automation just as readily as a handful of sensors for GAZZETA is a product with genuine flexibility.

Fleximodo IoT Parking Sensor Standard XL (Outdoor): Technical Profile of a Dual-Detection NB-IoT Parking Sensor

Specification	Detail
Detection method	3-axis magnetic field (magnetometer parking sensor) + nanoradar — dual detection technology for reliable parking occupancy detection
Variant	XL outdoor (larger form factor for open-area detection)
Mounting	Surface adaptor (non-invasive)
Connectivity	NB-IoT
Vehicle identification	IoT Permit Card 2.1 (BLE)
OPEX model	Monthly billing per sensor and per permit card
Ingress protection	IP68
Operating temperature	-40 to +85 °C

Operating across a -40 to +85 °C range raises a natural question: what is automatic temperature compensation, and why does it matter for a magnetometer parking sensor like the Sensor XL? Heat and cold both cause subtle drift in a magnetic field reading, which — left uncorrected — can produce false occupied/vacant readings as the seasons or even the time of day change. Fleximodo's sensors apply automatic temperature compensation in firmware, continuously adjusting the magnetometer's baseline against ambient temperature swings so that detection accuracy stays at around 99.96% whether the sensor is baking under summer sun on an exhibition forecourt or exposed to a Prague winter.

Frequently Asked Questions

Why would an event marketing company order parking sensors? Event marketing companies manage specialist parking challenges at exhibition grounds, trade fair venues, and sponsor activation zones — rotating exhibitors, VIP zones, and permit-based access control. The Sensor XL with E-Permit Card combination detects whether spaces are occupied and identifies which vehicles belong in which spaces — ideal for event venues where standard permit enforcement software alone is insufficient.

What is the monthly OPEX model? Monthly billing per sensor and per permit card, covering software, app, and connectivity. This pay-as-you-go model lowers the entry barrier for specialist deployments where upfront lifetime OPEX is impractical — clients whose deployment duration is uncertain, whose budget must be charged to specific events, or whose sensor counts are too small to justify enterprise commercial terms.

Why use a surface adaptor instead of core-drilled installation? The surface adaptor enables full Sensor XL functionality without structural modification to the underlying pavement — critical for temporary deployments, heritage surfaces, leased event spaces, or any location that must return to its original state after the installation period. GAZZETA's deployment likely serves an exhibition forecourt or event venue where permanent road cutting is not feasible, unlike in-ground parking sensors that require it.

What is automatic temperature compensation in a parking sensor? Automatic temperature compensation is a firmware-level correction that continuously adjusts a magnetometer parking sensor's readings as ambient temperature changes. Without it, heat and cold can cause magnetic-field drift that triggers false occupied or vacant readings. Fleximodo's sensors, including the Sensor XL used in this deployment, use automatic temperature compensation to hold detection accuracy at around 99.96% across extreme temperature swings, from -40 to +85 °C.
