Standardized Field Sobriety Testing (SFST) and Drug Recognition Expert (DRE) evaluations depend on an officer’s handwritten descriptions, which can limit the effectiveness of advanced impairment detection. Without evidentiary recording of eye movements, critical evidence regarding horizontal/vertical gaze nystagmus or pupil sizes may struggle during trial cross-examination in law enforcement.
The DAX Evidence Recorder provides an objective digital capture of the entire eye exam, making it a vital tool for law enforcement in advanced impairment detection. Operating in darkness with targeted infrared illumination, the system documents eye movement, records the officer's vocal commands, and logs subject comments, thereby creating a permanent, verifiable chain of evidentiary recording.
