Abstract
A chemical impairment detection system and method of use comprising a video surveillance system adapted to record a facial image of a tester, the video surveillance system having a camera with a lens having a field of view from which the camera views images and distinguishes whether those images have appropriate construction or contrast of light intensity. The invention further comprises a control and relay module having a proper view and position determiner adapted to determine whether the facial image of the tester is properly positioned within the field of view during a chemical impairment detection test, and a test prompter to alert the tester when to begin the chemical impairment detection test. The present invention further comprises a chemical impairment detection sampling device in operable communication with and responsive to the video surveillance system, the sampling device adapted to receive a chemical impairment detection test sample from the tester.
