§ 13 SächsDSG
Video surveillance of publicly accessible spaces
(1)The collection of personal data by means of optical-electronic devices (video surveillance), their storage and other processing shall only be lawful insofar as this is necessary for the performance of a task in the public interest or in the exercise of the right of domiciliary authority and there are no indications that the legitimate interests of the data subjects outweigh the interest in processing.
(2)Further processing for other purposes shall only be lawful insofar as this is necessary for the prevention of threats to public security, for the prosecution of criminal offences, for the assertion of legal claims, or for the protection of the legitimate interests of data subjects, in particular for remedying an existing lack of evidence.
(3)The fact of the video surveillance, the name and contact details of the controller, and the possibility of obtaining further information pursuant to Article 13 of Regulation (EU) 2016/679 from the controller shall be made recognisable by appropriate measures.
(4)Data stored pursuant to paragraph 1 shall be erased without undue delay, and no later than one month after collection, insofar as they are no longer necessary for the purposes referred to in paragraphs 1 and 2.
