Video Surveillance

A camera that fails to deliver a usable image at the decisive moment is worthless. This is exactly where many systems fail: too little light, the wrong focal length, unfavorable angles or a compression that swallows the decisive detail. We plan video surveillance systems (VSS) in line with the DIN EN 50132 standard series — with a clear focus on purpose, image quality and usability.

The starting point is defining the task per camera: is it about detection, observation, recognition or identification? These operational requirements determine the necessary pixel density, illumination, detection zones and frame rate. Only from this do the camera type, lens and location follow — not the other way around. This avoids expensive systems that fail to deliver court-usable images in the event of damage.

Data protection is not an afterthought but an integral part of the planning. Video surveillance interferes with the rights of employees, customers and passers-by and is only permissible under the conditions of the GDPR and German data protection law. We address the legal basis and purpose limitation, necessity and proportionality, detection zones and masking, retention periods, data-subject rights and the required documentation — including the record of processing activities and, where necessary, a data protection impact assessment.

Technically, we do not consider video surveillance in isolation. On request we integrate it with intrusion detection and access control into a unified system and connect it to a security control room. Video verification can help there to distinguish genuine events from false alarms and thus speed up intervention — a concrete, measurable benefit over a pure recording solution.

The result is a system that meets two requirements at once: it protects effectively and delivers usable images — and it does so in a legally sound way, without exposing the operator to data protection risk.
