EVHD means EyeVision Virtual Hardware Device. An EVHD represents the link between the hardware and the EyeVision-software.
Such a link is necessary because each hardware manufacturer offers a different interface to its hardware.
VIC is the level of abstraction for image acquisition devices. VIC stands for Video Input Channel.
A running EyeVision system consists of a Basic, Standard, Professional, a VIC and an IO module. e. g. EyeVision Standard + EVHD VIC Sentech GigE + EVHD IO PP.
EVHD VIC Sentech GigE for special hardware integration of GigE cameras by Sentech to the EyeVision software.
