The Genetec video archive is a proprietary multimedia container format developed by Genetec Inc. for use within its unified security platform. This format is primarily employed for storing and exporting video surveillance footage from Genetec Security Center systems to ensure chain of custody. Playback typically requires the specialized Genetec Video Player, as the file structure often incorporates watermarking and encryption features designed to prevent tampering during forensic analysis.
