Evidence files are always created in an Evidence Manager-proprietary format. This means that if an evidence file is meant for legal matters, you can only open it from Evidence Manager. Evidence Files can be available as a folder, or a single file. In either case, when you attempt to view the video evidence, an instance of Evidence Player is first created, and the video in question starts playing inside this instance.
Evidence Player is an application that can play evidence files. It is created every time you create an evidence file, along with the video that you exported. If you selected to create a single evidence file, Evidence Player is embedded inside the video, else, it is created in the same folder as the evidence file.
To open an evidence file:
Evidence files might be distributed in a removable media such as a USB, a CD, or a DVD.
Inside the evidence folder, you will see a file with a .avr, .avs, or a .video extension. This is the video that is rendered, and played inside the Evidence Player instance.
