Abstract: A real-time damper visual verification device and system for use in combination with a HVAC duct structure includes a camera being structured and disposed for generating image signals in response to an optical image and the camera being in connection with a computer processor for generating the optical image and a real-time clock display; the camera being positioned for viewing the damper blades of the HVAC duct structure; wherein a verification procedure includes operating of the plurality of damper blades between first and second movements, the first movement defining the damper blades moving from an open position to a closed position and the second movement defining the damper blades moving from a closed position and an open position; and in which the camera records the optical images of the first and second movements to provide a true visual verification of operation of the damper blades between the first and second movements.
