Mayfer,
I have now installed both the DS-2CD2342WD-I turret and the DS-2CD3345-I turret and -- in my opinion -- there is not a great deal of difference between the IR image capabilities of these two cameras.
Yes the DS-2CD2342WD-I does have better night vision quality than the DS-2CD3345-I...but the quality increase is not significant. I use four (4) turret at work for our outside cameras...but the outside areas we surveill are all lit by flood lights. In fact, I turn the IR off on all of these cameras and set them all to "Day" and the subsequent image is quite good IMO.
The recent night testing I am referring to was done in my unlit backyard and -- once again -- the night-time IR lighted image quality between the DS-2CD2342WD-I turret and the DS-2CD3345-I turret was not that great a differential. I apologize for not having video to share with you, but my testing was a subjective judgement split over two weekends. Not very scientific I'm afraid.
This said, the DS-2CD2342WD-I turret is a better quality build simply because of the metal mounting bracket and the fact that the turret locks in place with a set screw whereas the DS-2CD3345-I has no such screw and (as a result) it doesn't take much pressure to twist the DS-2CD3345-I to change the viewing angle of the camera.
I know it has been written that the DS-2CD2342WD-I has much better night vision capabilities because of it's "true WDR" but -- again in my subjective opinion -- while it is "better" it is not "a great deal better." And -- again IMO -- the DS-2CD2342WD-I is not worth two (2) times the cost of the DS-2CD3345-I.
In addition, the DS-2CD2342WD-I Western Region I purchased does have different setting options than my Chinese DS-2CD3345-I. For example, the xxx has ability to choose PAL or NTSC whereas the DS-2CD3345-I appears to be PAL "hard-coded." In addition, in the images below notice how you can sneak the pigtail under the metal bracket of the DS-2CD2342WD-I whereas you must drill a hole to free the DS-2CD3345-I pigtail.
My judgement may well be proved inferior in the future by a person who performs a more thorough scientific analysis, but, for now 'ol Q™ won't be buying any more DS-2CD2342WD-I cameras unless someone shows the that I've failed to consider some value.
