Being fairly new to the CCTV field, I don't yet have the experience to go to a customers site and say, "You should get a camera with a x lens here and a camera with a x lens over there"
I don't know what lens type/size would look like from any given point.
It would be great if there was a camera or device that would show you what would be seen from a mounted point.
Any www links or general rules of thumb would be appreciated.
Thank you in advance.
