A set of PTZ values associated with a video and a set of timestamps associated with the video are received. The set of PTZ values is generated (1) after a first command from a user to start recording PTZ changes, (2) before a second command from the user to stop recording the PTZ changes, and (3) based on sampling PTZ actions taken by the user, relative to the video, after the first command, and before the second command. Each PTZ value from the set of PTZ values has an associated timestamp from the set of timestamps that indicates a portion of the video from which that PTZ value was sampled. A modified video is generated based on the set of PTZ values and the set of timestamps.

A method for hybrid video encoding includes receiving, via a browser, a signal representing a requested media, and determining whether the browser is compatible with high efficiency video encoding (H.265). When the browser is compatible with H.265, the requested media is transmitted, via a first video encoder, in a non-transcoded, H.265 format. When the browser is incompatible with H.265, one of: (1) a H.265 version of the requested media is transcoded to a transcoded H.264 version when the requested media includes recorded video footage, (2) the H.265 version of the requested media is transcoded to the transcoded H.264 version when the requested media does not include recorded video footage and includes full resolution video footage, or (3) the requested media is transmitted via a second video encoder in a non-transcoded, H.264 format when the requested media does not include recorded video footage and does not include full resolution video footage.

Introduced here are surveillance systems and associated approaches for obfuscating biometric identifiers generated by, or available to, those surveillance systems for privacy reasons. In the event that a surveillance system generates a biometric identifier (e.g., by imaging a face of a person entering the premises of an organization), caution must be taken to only share the biometric identifier with individuals as necessary for security reasons. The approaches introduced here allow the privacy of persons being surveilled to be protected. Specifically, a computer program may selectively apply blurring as an impermanent mask to obfuscate each face in a digital image. This approach limits 'reidentification' of a given person to those scenarios where her identity must be determined.
