Which of the following is not considered a data protection consideration when collecting personal data via CCTV?

The duration of the video footage may not be considered a specific data protection consideration in the same direct way as the other options listed. While it is important to manage how long video footage is stored to comply with data minimization principles, it's not typically labeled as a “consideration” in the same manner as proportionality, lawfulness, and information provision.

Proportionality refers to ensuring that the use of CCTV is necessary and that the benefits outweigh any potential infringements on privacy. Lawfulness pertains to the requirement that personal data must be collected and processed in compliance with applicable laws, meaning there must be a legal basis for using CCTV. Information provision involves ensuring that individuals are informed about the presence of CCTV, the purpose of its use, and potential implications for their privacy.

While duration is relevant to data retention policies, it is a more operational detail rather than a core principle of data protection considerations compared to the other options mentioned. Thus, it is the least aligned with the framework of data protection considerations in the context of CCTV usage.
