Cropped video image?

fafaforza · Post by **fafaforza** » Mon Apr 15, 2013 5:03 pm

Does ZM do any video cropping by default? One of my cameras is not showing people's heads in one shot where I believe it did with whatever standalone DVR my building was using. Any way to check if it is being cropped somehow?
