Redaction is an add-on feature of Evidence Manager that has the ability to redact what you can see and hear in video recordings. Redaction can auto-detect faces, and can also be configured to detect other sensitive imagery that is ultimately redacted from your video evidence.
The top benefits of the Redaction feature are:

• Simple to use
  The Redaction feature is easy to use, and requires no complicated additional tools. You can access Evidence Manager like you normally do, and with the help of the redaction interface, redact portions of video and audio that must be filtered.
• Speedy redaction
  Redacting objects is speedy; you can either opt for auto redaction of objects, or manually select objects for redaction. In either case, Redaction will redact the chosen objects within a matter of minutes.
• Support for video and audio redaction
  The Redaction feature can redact video objects as well as the audio within videos. You can configure filters for video objects, and also choose to either beep or silence associated audio.
• Multiple types of redaction
  The Redaction feature supports different types of redaction – Automatic Face Detection, Auto Redact Object, and Static Object. By supporting different methods of redaction, you have greater control over the objects in your video file, and ultimately, the evidence.
• Greater control over redaction
  You can choose to redact objects in forward frames, backward frames, or throughout the entire video if you wish. This way, you can have greater control over how far and how long objects within your evidence files are redacted.

Redaction uses a concept called “elements” to identify sensitive imagery, and eventually redact the imagery. In this context, Redaction categorizes sensitive imagery into two types of elements as follows:

• Video element is a face, an object, a label, or any other item in a video that needs to be redacted. Using the Redaction feature, you can redact elements within a video that are sensitive.
• On the other hand, an audio element refers to sounds or speech (often names or explicit language) that needs to be redacted.
