How far will I see ?
Depending on the Field of View (FoV) of your camera and the resolution you chose for the camera feed to VidiReports, you will be able to detect faces at a certain distance.
VidiReports needs a minimal number of pixels to detect a face, and a bit more to detect “Expert” features like smiles or glasses.
Use this tool to calculate how far you will see with your hardware :
What lens do I need ?
What angles should I plan ?
