How to select 12mm lens size on DS-2CD2T42WD-I5 or DS-2CD2T42WD-I8

[Kent Smith]

(I haven't found this in the forum after searching, but couldn't figure out how to do a logical AND for the search string so maybe that is my problem.)

I am considering adding the DS-2CD2T42WD to my test setup of cameras and I want this one to be 12mm. Looking at the datasheet I see the -I5 has 4/6/12 and the -I8 has 6/12/16, but does that mean you can order one of those lenses in that model, or it comes with all three of those lenses?

If I order a -I8 do I still need to select the lens? And if that is true, what is otherwise different between the -I3, -I5, and -I8?

If it comes with all the lenses listed, I have no problem opening it up and changing it out.

You can order just ONE of these lens per model

If I order a -I8 do I still need to select the lens?

Yes

And if that is true, what is otherwise different between the -I3, -I5, and -I8?

IR range 30meters, 50meters and 80meters as its wrote here in the end: http://overseas.hikvision.com//uploadfile/image/10229_EFTPspec2SeriesR6(2X22FWD2X42FWD)DS2CD2T42WDI3I5I8.pdf

Dont know if its possible to change the lense as its a normal M12 lense mount. You might have a look at this: http://www.m12lenses.com/M12-Mount-Mega-Pixel-Lenses-s/21.htm

Thanks Cruunnerr. I may need to investigate that direction.
