What Accellence Technologies does

Accellence Technologies GmbH is an independent German software house founded in 1999 and headquartered in Hanover, specializing in video security and SCADA/process automation. The company develops and owns two core proprietary products: vimacc, a scalable, platform-independent video management system with a formal data privacy certificate that integrates as a component of Siemens Simatic WinCC Open Architecture; and EBÜS (Einheitliches BildübertragungsSystem), an integrative video management platform that unifies video streams from 100+ heterogeneous systems (Axis, Milestone, Genetec, Bosch, Hikvision, Avigilon, Honeywell, and others) under a single operator interface by transcoding all inputs to open JPEG format. EBÜS is formally recommended by the KA-Bild committee (German police, BHE, BDWS, ZVEI) and is recognized as a police-approved Bildempfangszentrale under the ÜEA-Richtlinie, anchoring the company's position in the German alarm receiving centre and police image transmission market.

The business model is predominantly professional services-driven: Accellence delivers bespoke software engineering, consulting, hardware qualification in its own video test lab, integration, commissioning, documentation, and training under service contracts, contracts for work and labour, and personnel leasing arrangements. Recurring revenue streams include vimacc and EBÜS software licensing (subscription/support), training services (vimacc, EBÜS, WinCC OA video courses, and IT security awareness training), and marketplace commissions via SCADA apps on the SloopTools digital platform for WinCC OA users. Customer segments are organized vertically around traffic and transport infrastructure (tunnels, airports, AGT systems, locks, rail), building and industrial site security, pharmaceutical sites (Merck), biotechnology, and alarm receiving and security Leitstellen (Protection One, KÖTTER, Securitas, ADT), with notable project deployments including 830+ cameras for Merck, 3,600 cameras across Lower Saxony's seven tunnels, and the APM Oakland cable-drawn automated people mover.

Accellence sells primarily through direct enterprise field sales targeting large infrastructure operators, augmented by channel partners: the Siemens/ETM WinCC OA ecosystem, Axis Communications, the SloopTools marketplace, and industry associations (KA-Bild, BHE, BDWS, ZVEI). Marketing demand generation runs through industry events (SWB-Tagung, WinCC OA Neuheiten-Schulung), webinars (BHE cyber security for VSS), and news/blog content. The company is DIN EN ISO 9001:2000 certified, employs ISTQB-certified testers, and operates with C++-centric development across Windows and Linux under V-model, agile (SCRUM), and waterfall methodologies. Managing Directors Frank Christ and Dr. Heinz Stephanblome lead a team of 11-50 employees, with no disclosed external funding or parent company.

• Axis CommunicationscoreTechnology or Integration · 31 March 2026Accellence and Axis Communications have deepened their long-standing successful partnership. Through the ACS Pro integration, EBÜS can now be connected to numerous alarm receiving centres. Axis provides IP-based video hardware (cameras, encoders) while EBÜS provides the integrative video management layer, enabling heterogeneous alarm receiving centre deployments.
• Siemens / ETM professional controlcoreTechnology or IntegrationAccellence is a certified integration partner for Simatic WinCC Open Architecture (WinCC OA), a SCADA platform developed by Siemens affiliate ETM (Eisenstadt, Austria). vimacc functions as a product component of WinCC OA, and Accellence participates in WinCC OA training events and develops software solutions on the WinCC OA platform. The company also provides WinCC OA video/SCADA training jointly with Siemens.
• SloopToolsminorChannel Partner/ Reseller/ DistributorSloopTools is a digital marketplace (app store) for WinCC OA add-on software. Accellence publishes six SCADA applications on the platform: BurningTools Extension, Captcha Control, DateTime Control, Joystick Control, ONVIF Discovery Extension, and Timeline Control. This enables Accellence to reach an international WinCC OA user community.
• KA-Bild (Koordinierungsausschuss Bildübertragung) – Police, BHE, BDWS, ZVEIcoreStrategic or Co-development PartnerSince 2000, representatives of German police (Polizei Führungs-Akademie), BDSW (Bundesverband der Sicherheitswirtschaft), BHE (Bundesverband der Hersteller und Errichter von Sicherheitssystemen), and ZVEI (Zentralverband Elektrotechnik- und Elektronikindustrie) have collaborated in the KA-Bild committee to address video system incompatibility. This collaboration produced EBÜS as the recommended standard for alarm receiving centres and police image transmission (ÜEA-Richtlinie). EBÜS was explicitly endorsed after comprehensive testing by police.

• Dallmeier: German manufacturer of VMS and video surveillance systems for casinos, logistics, stadiums, and safe-city applications. Comparable as a German-speaking, vertically-integrated VMS vendor targeting regulated, safety-critical installations.
• Genetec: Canadian unified security platform offering Security Center (VMS, access control, ALPR). Closely comparable in serving enterprise and public-safety command centres, including transportation and government customers, and competing head-to-head in integrated operations centre use cases.
• AxxonSoft: International VMS and PSIM vendor serving alarm receiving centres, transportation, and industrial customers. Comparable integrative VMS play; listed among EBÜS's supported video systems.
• SeeTec (by Qognify): European VMS vendor (now part of Qognify) with strong presence in German alarm receiving centres and retail/logistics verticals. Directly comparable to EBÜS in the German NSL/ARC segment and listed among EBÜS's 100+ supported integrations.
