In Switzerland, video surveillance is strictly regulated by data protection legislation. Anyone filmed must be clearly and visibly informed of the presence of cameras. This applies to both employees and visitors, customers or external service providers.
Information can be provided via a sign or signage placed at the entrance to the monitored areas. This sign must state that the area is under video surveillance and, ideally, indicate who is responsible for the system as well as the purpose of the surveillance (e.g., security of goods and people).
The installation of cameras must always respect proportionality and privacy. It is forbidden to film areas where people expect privacy, such as changing rooms, toilets or rest rooms. For employees, surveillance should not be used for the purpose of permanent monitoring of activity.
Before any installation, it is recommended to assess the necessity of the system and document the data protection measures implemented. Transparent information strengthens trust and ensures compliance with Swiss legal requirements.
