By 2024, SSG’s technical team was managing five manufacturer relationships, three integration layers, and panels with lead times past 16 weeks. Every new installation began with a compatibility audit — and too often, at least one question came back negative. This Roombanker case study examines how Romania’s established security provider replaced that fragmented approach with a single wireless platform, and the measurable impact across 16 sites in 90 days.
The Challenge: Fragmentation at Scale
SSG has served the Romanian security market for over a decade, providing intrusion detection, video surveillance, and access control to residential and commercial clients. Like many integrators who grew through aggregation, their model relied on assembling solutions from multiple manufacturers. By late 2024, the costs of fragmentation had become structural.
Compliance overhead. Romania follows the EN 50131 alarm system standard, and recent enforcement made certification documentation a requirement for insurance approvals. SSG tracked compliance paperwork across multiple manufacturers, each with different grade classifications and renewal timelines.
Supply chain instability. Lead times for critical panel components stretched to 12-16 weeks through 2023-2024. SSG overstocked to maintain availability, tying up capital and warehouse space.
Integration instability. The custom middleware unifying SSG’s multi-vendor deployments required ongoing maintenance. Every firmware update risked breaking the integration. One SSG engineer described it as “building on rented land.”
The Search for a Unified Platform
In late 2024, SSG evaluated four single-ecosystem platforms against specific criteria: EN 50131 compliance out of the box, 868 MHz band support for the Romanian alarm frequency allocation, and sufficient device density to cover medium-to-large sites without repeaters.
SSG selected Roombanker on two factors that distinguished it from alternatives.
RBF Protocol range. RBF is Roombanker’s proprietary wireless communication protocol, achieving 3500 meters (2.17 miles) in open air with stable penetration through reinforced concrete and brick — the standard construction materials across Romanian buildings. For SSG, this meant fewer repeaters and lower hardware costs per site.
Vertical integration. Roombanker designs its own RBF SIP Chip — a self-developed low-power system-in-package — rather than integrating off-the-shelf radio modules. For SSG’s technical team, this meant consistent radio performance across every device in the ecosystem.
Roombanker Romania Case Study: Full RBF Ecosystem Deployment
SSG deployed the Roombanker Hub (R2) as the central controller for each site, paired with Roombanker PIR motion sensors, door/window sensors, indoor and outdoor sirens, keypads, keyfobs, smoke detectors, water leak detectors, and smart relays. The entire fleet is managed through the RB Link mobile app for on-site configuration and the Roombanker Portal for centralized fleet management.
Deployment Metrics: 16 Sites, 90 Days
The pilot launched in Q2 2025 across 12 residential properties and 4 small commercial offices in Bucharest. Sites ranged from an 80 m² apartment to a 450 m² villa with detached garage and garden.
| Metric | Result |
|---|---|
| Sites covered | 12 residential + 4 commercial |
| Maximum devices per hub | 128 |
| Hubs per 450 m² site | 1 |
| Repeaters required | 0 across all 16 sites |
| Frequency band | 868 MHz (Romania pre-configured) |
| Average pairing time | 8 seconds per device |
For more detail, see the RBF Protocol technical breakdown.
The 868 MHz band was pre-configured at the factory, eliminating radio configuration during installation. One SSG lead installer: “It took longer to open the box than to pair the sensor.”
Measurable Results After 90 Days
After 90 days, SSG documented three measurable outcomes.
Installation time reduced by 35%. A residential installation that previously required two engineers for 4-5 hours was completed by a single engineer in under 3 hours. The elimination of compatibility checks and multi-brand pairing was the primary driver.
Wireless stability improved by 50%. Signal drop incidents — measured as loss-of-communication events per site per month — decreased by half compared to SSG’s multi-vendor baseline. In RF-dense Bucharest neighborhoods, the RBF Protocol’s adaptive frequency management maintained links where the previous setup had experienced intermittent disconnects.
128 devices per single hub. Commercial sites that previously required two panels to cover all zones now operate from a single Roombanker Hub. Equipment costs per site decreased by approximately 30%.
The EN 50131 enforcement framework continues to evolve across European markets, making single-platform compliance documentation an operational advantage for integrators.
What SSG’s Installers Found Different
Previous multi-brand installations required navigating three configuration interfaces and manually setting radio channels. With Roombanker, device pairing averaged 8 seconds — the Hub automatically managed channel allocation. For a team managing 20+ installations per month, that saved roughly two engineer-days per week across the crew.
The Partner’s Perspective
“We went into the pilot expecting to prove a concept. What we found was a platform that solved problems we had accepted as normal. The 35% reduction in installation time was measurable from the first month — our engineers reported it without being asked. What mattered more to us strategically was the supply stability. Knowing that every device in our inventory works with every hub, that we’re not juggling five supplier relationships, that the certification package is one document — that changes how we plan our growth.”

How many devices can a single Roombanker Hub support?
A single R2 Hub supports up to 128 wireless sensors and detectors — enough to cover a 16-site deployment like SSG’s pilot without additional hardware.
What frequency band does Roombanker use in Romania?
868 MHz, the EU-standard sub-GHz band. Every device SSG received was pre-configured for Romanian frequency compliance, eliminating per-device setup. The RBF Protocol continuously scans for interference and switches channels dynamically.
How long does it take to pair a new sensor?
Under 8 seconds per device, using the RB Link mobile app. SSG installers reported spending less time on pairing than on physical mounting.
How far can a single Hub cover?
SSG’s Bucharest pilot tested sites from 80 m² apartments to 450 m² villas — the R2 Hub covered every site without a single repeater. Roombanker’s product specifications rate the RBF Protocol at up to 2,500 m² in open-air conditions. Across all 16 pilot sites, zero repeaters were required, and packet delivery exceeded 95% through Romanian reinforced concrete and brick construction.
A single Roombanker Hub reliably covered 350 m² residential floors and up to 500 m² open-plan commercial spaces without repeaters in internal testing across Romanian building types, with 95%+ packet delivery through reinforced concrete floors and brick walls.
For the installer: fewer devices to mount, fewer pairing steps, one less variable to troubleshoot.
Nationwide Deployment
Following the pilot, SSG expanded to Cluj-Napoca and Timișoara, targeting 200+ sites by end of 2026. Warehousing is simplified — one device family instead of five — and new-engineer training dropped from weeks to days.
