FaceVACS-DBScan LE combines Cognitec’s renowned image database search technology with powerful video inspection tools for a multitude of investigation use cases.

The market-leading technology helps law enforcement staff to increase the speed and accuracy of criminal investigations, allowing them to act upon match results in the critical time period after a crime has been committed.

After importing video material, agents can find known or unknown persons in multiple videos to quickly narrow down suspect investigations. The technology then compares the facial images from video material or from any other source to smaller local or multi-million central image databases, and instantly displays a candidate list of possible matches.

The Investigation toolset includes various filters to enhance image quality and improve match results. It also provides a set of inspection tools to compare images side by side and measure facial features. Operators can develop watch lists of potential matches while recording a full audit trail for each step in the process.
