CCTV Object Detection

API change history

CCTV API contains information on object detections taken from approximately 40 CCTV cameras throughout Glasgow. Detection data is available from 2021-10-18. CCTV images are translated into object counts using an algorithm. Objects counted include ‘person’, ‘car’, ‘bicycle’, ‘motorcycle’, ‘bus’ and ‘truck’.

The data is generated and owned by Glasgow City Council in conjunction with Urban Big Data Centre at the University of Glasgow. Copyright © Glasgow City Council 2022. This dataset is available for use under the Open Government Licence.
