Swapped some lenses out

[Hoog23]

So I purchased a couple of lenses online from M12 Lenses and decided to swap them out on a 1.3 bullet I had laying around.

This is what I purchased:F1.8 Mega Pixel CCTV Board Lens 6mm and 12mm

Ebay would have been a lot cheaper but these arrived 2 day shipping and over all I was pretty happy with the outcome of my bench testing.

Here is a pic of them compared to the original 3.6 lens (which is on the left).

Here is the diss-assembly and pic of the 12mm installed.

Here are a couple of shots in my office looking about 10 feet away.

6mm

12mm

I bought a Hikvision DS-2CD2632F-I to try out the zoom in the back of my house once the weather warms up but I think I may just stick the 12mm on another Dahua and not try to mix brands (I have a Eyesurv NVR).

Cool, thanks for the comparison shots...

The images look vary barrel distorted (but clean) - even on the original camera lens - is that normal for the Dahuas?

I've got 5 cameras outside and only notice it on the one in the driveway that is the closest to what I am viewing (for lack of the technical term). It is also the only 1.3mb cam that I still have in use.
