There should be no GDPR or privacy issues when installing time lapse cameras. This even applies if an individual can be readily identified, providing of course there is a legitimate reason for installing the cameras e.g. for marketing purposes.
We will always set our time lapse cameras to focus on the client’s project. There may be instances however where properties, or individuals, could be captured that are outside the site. This is allowable, as the capture of this data is inadvertent, and as a consequence of the client needing the camera to be in that position to capture their project.
While it is not a requirement, some companies may wish to erect a sign to make neighbours aware that time lapse cameras have been installed. This would also alert those who are working on the site.
It is worth pointing out if you install CCTV then different rules apply.
Please be aware that this is our view based on our understanding of the GDPR and should not be taken as legal advice. It is up to the respective individual or companies to ensure that they are fully compliant with all laws and regulations.
