Does anyone have pdf of the op manual for the MVR series? They no longer support it on their website.

We are not a "usual" user of CCTV style products but have been experimenting with some for a particular project. One thing I've found is that it appears that it is impossible (by design?) to back focus a "vari-focal" lens. When you do get focus it has limited depth-of-field. Does anyone know of a 1/3" megapixel zoom lens that will back focus? Also, is there a way to increase depth-of-filed using a CCTV style box camera? Thanks so much for your assistance.
