The phrase refers to the acquisition of digital video files recorded by surveillance or security systems. This process typically involves transferring the footage from the recording device (e.g., a digital video recorder or network video recorder) to a computer or other storage medium for review, analysis, or archival purposes. For instance, a business owner might need to obtain video evidence of a shoplifting incident for submission to law enforcement.
The ability to retrieve such recordings is critical for various reasons, including security, law enforcement, and insurance claims. It provides verifiable documentation of events, aiding in investigations, deterring criminal activity, and resolving disputes. Historically, accessing this data required physical access to the recording device. Modern systems often offer remote access capabilities, allowing authorized users to retrieve footage from anywhere with an internet connection.
