Digital Forensic Analysis in a contractual dispute and building CCTV data

A case study on work that Notion Digital Forensics have completed.

A group of businesses in a multi-level building were involved in a contractual dispute with their strata manager over a long-term cleaning contract. The businesses claimed that the cleaning services provided by the strata manager were not adequate and sought evidence to support their case for termination of the contract. A digital forensic analysis of the building’s CCTV system was conducted to provide insight into the cleaning activities.


The objective of the digital forensic analysis was to examine the CCTV footage of the building to determine the extent of cleaning performed by the cleaning company.


Notion Digital Forensics worked with the solicitor before the contract cleaning company was served. We acquired the hard drive evidence prior to serving the cleaning company to preserve evidence. We then conducted a motion analysis of the footage, quickly sorting through many days of video. We then produce this into a finished video, so the parties could see what was going on.


The digital forensic analysis provided evidence of inadequate cleaning on the specified dates. This evidence was useful for the businesses in their contractual dispute with the strata manager, supporting their case for termination of the cleaning contract.
