Different cameras designed for different purposes. It all comes down to what you are trying to achieve and why. To give you an idea, we recently deployed a whole range of MV32's and MV22's within a hospital. Hospitals obviously have dining areas and hallways. We used the MV22s at each end of the hallways (one at each end facing each other) which enables us to cover the entire hallway and capture events. The MV32's are good for open / dining areas for example, as you can place them directly in the middle of the room and gain 360 view. A MV32 would not be suitable for a hallways, especially if you were mounting them at the door way entry for example, because you would see a wall on the rear and the image at the front, but the zoom wouldn't be there to identify individuals. The MV22's, we zoom them in slightly to create cross-over at each end. The MV12W and N are also excellent options for door entries (especially if there are multiple entries), we actually usually deploy more of these then any other camera.
