Video surveillance

Data protection glossary · 1 minute read

Video surveillance is the monitoring of rooms or areas using optical-electronic equipment, and it is permitted under data protection law if it is necessary and proportionate.

Private companies generally base video surveillance on their legitimate interest, for example protection against theft or vandalism. This must be balanced against the interests of the people filmed. Areas such as changing rooms, toilets or break rooms are off limits.

Video surveillance must be made apparent by clearly visible signs that contain the key information and refer to the full privacy information.

Retention period and employees

Recordings must be deleted as soon as they are no longer needed. The supervisory authorities regularly consider a retention period of up to 72 hours appropriate; longer periods must be justified.

Where employees are recorded, the works council has a right of co-determination. Systematic large-scale monitoring of publicly accessible areas requires a data protection impact assessment.
