Discrimination Level

Definition
Specifies a capacity to recognize a target of interest according to a given level of discrimination.

You can use video for identifying a wide range of detail, from motion detection to positive identification of a person for forensic evidence. Not every video system needs to be capable of performing positive identification. Select a video system that conforms to the requirements the application needs, without over- or under- specifying the system.

Use Characteristics
Consider:  What level of discrimination do you need to recognize a target of interest?
