The use of surveillance cameras on one's own property is generally permitted, as long as no public areas or neighboring properties are filmed. The cameras may only view one's own property, and persons entering the property must be informed of the surveillance. In apartment buildings, the surveillance of common areas or other people's apartments is prohibited.
Dummy cameras are only permitted if they don't appear deceptively real and don't monitor unfamiliar areas. Doorbells with camera functionality are permitted if they only transmit images after the doorbell is pressed and if they are not permanently stored.
Recordings may not be stored for longer than 72 hours, and the storage technology used must comply with data protection requirements. Following these rules can help avoid legal problems and fines.
