Wie SSG Rumänien die Installation von Sicherheitssystemen um 35 % reduzierte

By early 2025, SSG’s technical team was managing five separate manufacturer relationships to deliver what should have been a single security system. Every new installation required a compatibility check across three integration layers. Panel lead times stretched past 16 weeks. The middleware that tied together multi-vendor components broke on average once every two firmware updates. This case study documents how one of Romania’s established security providers replaced that fragmented model with a single wireless ecosystem — and what the measured data showed after 90 days across 16 sites.

Customer Profile: SSG Romania

SSG is a Romanian security solutions provider serving residential and commercial markets. Founded in 2012, the company provides intrusion detection, video surveillance, and access control systems to property owners, property managers, and small-to-medium businesses. Their technical team of 12 installers covers the Bucharest metropolitan area, with regional operations expanding to Cluj-Napoca, Timișoara, and Constanța since 2020.

Like many integrators who grew through technology aggregation, SSG’s product lineup had been assembled piece by piece — PIR motion sensors from one manufacturer, control panels from another, cameras from a third, all connected through custom middleware. Each component addition solved an immediate deployment need but compounded the system’s long-term complexity.

The Problem: Fragmentation Costs Were No Longer Sustainable

SSG’s technical director identified four structural costs that had grown with the company’s multi-vendor approach.

Supply chain risk. Critical panel components carried 12-to-16-week lead times through 2023 and 2024, according to SSG’s procurement records. The company overstocked to maintain availability, tying up an estimated EUR 45,000 in excess inventory across five supplier lines.

Mehraufwand durch die Einhaltung der Vorschriften. Romania follows the EN 50131 alarm system standard. With devices sourced from five manufacturers, SSG tracked certification documentation across multiple grade classifications and renewal timelines. Each new product required individual verification against Romanian regulatory requirements, adding approximately 4-6 hours of administrative work per product introduction (SSG internal compliance workflow audit, Q4 2024).

Integration maintenance. The custom middleware layer that unified SSG’s multi-vendor deployments required ongoing patching. Every firmware update from any manufacturer risked breaking the integration. SSG estimated 8-10 engineer-hours per month were spent on cross-brand compatibility testing — hours that could have been spent on revenue-generating installations (SSG engineering time allocation report, FY 2024).

Installer inefficiency. Field technicians carried three configuration interfaces to each job site. Pairing sequences, app workflows, and troubleshooting procedures differed by manufacturer. A standard residential installation that should have taken one visit sometimes required a follow-up when cross-brand pairing failed on site.

“The fragmentation cost was not just in money — it was in the time of our best engineers. We were spending more effort keeping the system working than growing the business.”

The Search for a Single-Platform Alternative

In late 2024, SSG evaluated four single-ecosystem platforms. The evaluation criteria were specific to the Romanian market.

868 MHz band support. Romania, like the rest of the EU, allocates sub-GHz frequencies for alarm system communication. Any platform operating primarily on 2.4 GHz (Wi-Fi or Zigbee) would face penetration issues through the reinforced concrete and brick construction standard in Romanian residential buildings.

EN 50131 compliance across the full product line. Not just the hub — every sensor, siren, and detector needed to carry the same certification documentation.

Device density per hub. Medium-to-large sites (300-500 m²) and properties with outbuildings required sufficient device capacity without adding secondary panels.

Supply stability. SSG needed a manufacturer with direct production control, not a brand that assembled third-party components.

SSG ausgewählt Roombanker on two factors that distinguished it from the alternatives.

Anwendungsbereich des RBF-Protokolls. RBF is Roombanker’s proprietary wireless communication protocol, achieving 3500 meters (2.17 miles) in open air with tested penetration through reinforced concrete floors and brick walls — the standard construction materials across Romanian buildings. For SSG, this meant fewer repeaters per site. SSG’s RF site survey confirmed that in a three-floor Bucharest apartment building with 20 cm reinforced concrete slabs, the RBF signal at 868 MHz maintained -95 dBm at the hub from the top floor, while the 2.4 GHz sensors they had been using measured -110 dBm at half the distance (SSG internal RF survey, November 2024, n=4 buildings).

Vertical silicon 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 every device in the ecosystem used the same radio implementation, eliminating the RF performance variance they had experienced mixing brands.

Deployment: 16 Sites in 90 Days

The pilot launched in Q2 2025 across 12 residential properties and 4 small commercial offices in the Bucharest metropolitan area. Sites ranged from an 80 m² city-center apartment to a 450 m² villa with detached garage and garden.

Equipment deployed per site (typical configuration): Roombanker Nabe (R2) as central controller, paired with Roombanker PIR Motion Sensors (indoor), Door/Window Magnetic Sensors, Indoor Alarm Siren, Alarm Keypad, Keyfob, and — for sites requiring fire and flood protection — Smoke Detectors and Water Leak Detectors. One commercial office also included Smart Relays for lighting integration.

Every device shipped pre-configured for the 868 MHz band. The RB Link mobile app handled all configuration on site.

Installation workflow after the switch. An SSG installer arrived on site, mounted the hub and sensors, opened RB Link on a smartphone, and paired devices. Average pairing time: 8 seconds per device, measured across 240+ device pairings during the pilot (SSG installer field log, Q2 2025). The hub automatically managed radio channel allocation. No compatibility check was needed between devices — all sensors were from the same ecosystem.

Measurable Results: Before-and-After Comparison

SSG tracked six metrics comparing the last 30 days of multi-vendor installations (baseline, Q1 2025, 10 comparable sites) against the first 90 days using the Roombanker ecosystem (pilot, Q2 2025, 16 sites).

Data provenance (all figures from SSG internal records unless otherwise noted):

• Installation time: SSG time tracking system. Baseline period: March 2025, 10 multi-vendor residential installations. Pilot period: April-June 2025, 16 Roombanker installations. Sites matched by size and complexity.

• Signal drop events: SSG network monitoring platform. Baseline: 30-day continuous monitoring on 10 multi-vendor sites in Q1 2025. Pilot: 90-day monitoring on 16 RBF-equipped sites in Q2 2025. A “drop event” is defined as a loss of bidirectional communication lasting more than 30 seconds.

• Equipment cost: SSG procurement records, comparing bill of materials for a 450 m² villa with 12 sensors, 2 sirens, 1 keypad, 2 keyfobs under both configurations. Multi-vendor pricing includes volume discounts at time of purchase.

• Repeater count: SSG site survey and installation completion reports.

• Device density: Multi-vendor baseline reflects panel capacity limitations documented in SSG equipment inventory records.

What drove the 35% reduction in installation time. The improvement came from three specific changes. First, eliminating compatibility checks saved an average of 30 minutes per installation. Second, using a single configuration app (RB Link) removed the 15-20 minutes previously spent switching between manufacturer tools. Third, the pre-configured 868 MHz band eliminated radio setup — one SSG installer noted: “It took longer to open the box than to pair the sensor.”

What drove the 50% reduction in signal drop events. The improvement was primarily frequency-related. SSG’s previous multi-vendor deployments relied on 2.4 GHz Wi-Fi-based sensors in some zones. In Bucharest’s RF-dense residential neighborhoods, 2.4 GHz band congestion from co-located Wi-Fi networks caused intermittent disconnections. The RBF Protocol operates on 868 MHz (sub-GHz), which is less congested and propagates differently through reinforced concrete. The 2-4 drop events per week that remained in the pilot occurred exclusively at edge-of-range sensor positions, which SSG addressed by repositioning sensors by less than 2 meters in two cases.

Was die Installateure von SSG anders fanden

SSG’s installers reported three operational changes in the first month of the pilot, documented during weekly team stand-ups.

One app, one workflow. Bei bisherigen Installationen mit mehreren Marken war die Navigation durch drei Konfigurationsschnittstellen und die manuelle Einstellung der Funkkanäle erforderlich. Mit Roombanker, all configuration happened in RB Link. The hub automatically managed channel allocation based on the 868 MHz band plan.

Zero device failures out of the box. Across all 240+ devices deployed in the pilot, SSG recorded zero returns due to manufacturing defects or pairing failures. Every device connected on the first attempt. This compared to an average of 2-3 DOA (dead on arrival) or pairing-failed devices per 100 units under their previous multi-vendor supply chain (SSG equipment receiving logs, FY 2024).

Simplified troubleshooting. When a signal issue did arise (2-4 events per week across all 16 sites), diagnostic information was available in a single dashboard instead of requiring logins to multiple manufacturer portals. The average time to identify and resolve a drop event decreased from approximately 45 minutes under the multi-vendor setup to under 15 minutes with Roombanker, according to SSG’s service desk records.

“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. From a procurement perspective, the supply stability was the bigger strategic win: knowing that every device in inventory works with every hub, that certification paperwork is one package, not five — that changes how we forecast growth.”

From Pilot to Nationwide Expansion

Based on the pilot data, SSG moved to national rollout in Q3 2025. The expansion covers Cluj-Napoca, Timișoara, and Constanța, targeting 200+ installations by the end of 2026.

The operational impact of the switch was not limited to installation speed.

Warehouse simplification. SSG reduced its active SKU count from 45+ multi-vendor line items to 15 Roombanker device types (SSG inventory management records, Q3 2025). Spare parts inventory — previously held across five manufacturer minimum order quantities — now covers the entire installed base with one product family.

Kompressionstraining. New engineer onboarding, previously requiring familiarity with five device ecosystems and three configuration tools, now requires one system. SSG reported that new-hire time-to-productivity dropped from approximately 3 weeks to 8 working days (SSG onboarding records, Q3 2025).

Compliance consolidation. All devices carry CE, RoHS, and EN 18031-1 (EU cybersecurity standard for radio equipment, applicable from 2025) compliance documentation as a single package, eliminating the per-product verification process.

Key Takeaways for Security Distributors

SSG’s experience offers a pattern that security distributors in other European markets can evaluate against their own operations.

1. Measure multi-vendor carrying costs before evaluating a switch.

SSG’s decision to consolidate was driven by identifiable, quantified costs: EUR 45,000 in excess inventory, 8-10 engineer-hours per month in compatibility testing, 12-16 week lead times. Distributors considering platform consolidation should document their own fragmentation costs first — the data clarifies the business case.

2. Test wireless performance in your local building stock before committing.

SSG’s RF site survey tested RBF signal penetration through Romanian reinforced concrete and brick construction before the pilot began. The same protocol will perform differently in timber-frame buildings common in Northern Europe, or in steel-frame commercial construction. Run a signal survey on 3-5 representative sites in your market.

3. Verify certification coverage across the full product line.

SSG’s evaluation included compliance documentation for every device, not just the hub. EN 18031-1 enforcement affects all radio equipment sold in the EU from 2025. Confirm that your preferred platform’s sensors, detectors, and accessories carry the same certifications as the hub — gaps in the product line create the same fragmentation problem you are trying to solve.

4. Run a 30-day pilot on 5-10 typical sites before scaling.

SSG’s 16-site pilot provided enough data to confirm the thesis without betting the entire installation pipeline. Measure installation time, device failure rate, signal stability, and installer feedback. Let the data — not supplier marketing — make the decision.

Häufige Fragen zum Großhandel mit Lebensmitteln und Getränken

Welche Funkfrequenz verwendet Roombanker Verwendung in Rumänien?

Roombanker devices operate on the 868 MHz band (EU-standard sub-GHz frequency for alarm systems) when deployed in Romania and across the European market. Every device is pre-configured at the factory for local frequency compliance. The RBF Protocol continuously scans for interference on the 868 MHz band and switches channels dynamically.

Wie viele Geräte kann ein einzelnes Gerät Roombanker Hub-Unterstützung?

Das Roombanker Hub R2 supports up to 128 wireless devices. In SSG’s 16-site pilot, typical deployments used 20-45 devices per hub depending on site size. The 128-device capacity means most residential and small-to-medium commercial sites operate from a single hub without additional panels.

How long does sensor pairing take with the RB Link app?

SSG measured an average pairing time of 8 seconds per device across 240+ pairings during their pilot. The hub manages radio channel allocation automatically — no manual frequency configuration is required.

Beeinflusst die Roombanker work through reinforced concrete?

Yes. The RBF Protocol operates at 868 MHz, which propagates through reinforced concrete and brick masonry more effectively than 2.4 GHz signals. SSG’s RF site survey confirmed -95 dBm signal reception through 20 cm concrete slabs at full building height. The protocol’s 3500-meter (2.17-mile) open-air range means that in-building penetration is limited by construction materials, not protocol capacity.

Welche Zertifizierungen Roombanker devices carry?

Jede Roombanker device carries CE, RoHS, and EN 18031-1 compliance certification at the point of shipment. The full compliance documentation is provided as a single package covering the entire product line.
