audio video evidence

Audio video evidence is most always an intentional recording of a past event. A sample of an audio video recording is a CCTV surveillance recording. Some of the time people create audio video recordings intentionally, other times they are created by accident. Either way they are very useful as evidence in court.
It has been said that audio video evidence is better than eye witness evidence. This is because people tend to forget details that are permanent in the recorded version. These recordings are very effective in communicating a series of events as they originally and naturally occurred.
Analogue audio recordings have an expected shelf life of 25 years when stored properly. They can be transferred to digital form and last indefinitely.
