Depending on the scenario, I would look at the MV93 (new and 3rd Generation) as it has much better resolution than the MV32 (2nd Generation). Check the datasheet out here. The other big thing in my eyes is that the MV93 has IR illuminators so it can go monochrome (night mode) and be able to see in very low light areas and at night. The MV32 doesn't have this capability for nightmode. The MV93 also is IP67 and IK10+ rated so you could use it outdoors as well.
