Sandersfeld Security Technology

What Sandersfeld Security Technology does

Sandersfeld Sicherheitstechnik GmbH is a family-owned German security and IT services group headquartered in Leer, East Frisia, founded on May 3, 1984 by Helmuth Sandersfeld. The company installs, maintains, and monitors electronic security systems — intrusion detection, fire alarm, video surveillance, access control and time tracking, and smoke/heat extraction systems — for residential, commercial, and industrial clients. Its core differentiator is the proprietary Europa-Leitstelle, a 24/7 alarm receiving center certified to the European norm DIN EN 50518, making it one of few such certified centers in Germany; the group also holds VdS recognition for fire and intrusion installations, BHE certification, DIN 14675 certification, and listing with the Lower Saxony State Criminal Investigation Office (LKA).

The group operates three legal entities: the parent company plus two wholly-owned subsidiaries — Certech Sicherheitssysteme GmbH (video technology, est. 1994) and Projekt Sicherheit GmbH (VdS-certified security guard and patrol services, est. 2004) — providing 'security from a single source'. A parallel Hausnotruf (personal emergency response) product line, including mobile GPS tracking and dementia tracking, serves the elderly care segment. On the IT side, the group delivers managed IT security, business telephone systems (innovaphone, Avaya), network and infrastructure (terra, Cambium, Brother), and media/conference technology (Promethean, Relens). Headcount is approximately 180+, with regional sales coverage across Weser-Ems-Elbe-Gebiet, Ruhrgebiet, and Bremerland, supplemented by nationwide reach through the seseNET35 network of 21 partner companies. Revenue is generated through a mix of professional services (installation, maintenance), recurring subscriptions (24/7 monitoring, Hausnotruf), and hardware sales (IT infrastructure), with pricing not publicly disclosed.
