Note to members: This test includes two Hikvision models, but not others, because the DS-2CD2383G0-I was recommended by multiple members as their best performing 8MP model. However, it is not available in North America. The latest generation 8MP model currently shipping in North America is the DS-2CD2385FWD-I. We've included both in the test for completeness.

From my humble experience, TVT NVR's are as reliable as a ripped condom.

Hi,
I'm quite surprised of bandwidth on HIKVision compare to others, they were using VBR with no limit same as others ? Such low bitrate is common with HIKVision cameras ?
Also, concerning the low lux effect, the setting was the same concerning DNR and slow shutter ? We noticed these settings can improve the quality on fixed image, but the image get so bad once there is motion (tested on IPC3618 from Uniview).

Hi IPVM Team,
Thanks for your dedicated work to this shootout testing.
As stated in page 9-10, Uniview 3618's IR Evenness performance is best, 'notably stronger than others', while on the 'Centre VS. edge illumination comparison' at page 11, Uniview’s camera was ranked 4th out of 5 cameras.
Compare these two images in the article, we found that this is a wrong Uniview image in the comparison table, we believe that we are higher than 4th ranking if correct Uniview IR performance image is used in this comparison table.
Again, thanks for your valuable testing and we'll put efforts on improving our products as always.

i would suggest to start doing moving video night time tests for the IR shots for real world use purposes. I do like the tests with the rez charts but i think you should add an additional moving test because rarely will subjects stand still in the real world. Some of these that rank so high on the stand still rez chart probably wouldn't perform as well as some of the others than ranked lower if we did a moving test.
They put the shutter speed so low that for a still image, the image looks great, but when someone moves, the image is blurred and nearly useless.

Uniview was 2.8mm, TVT 3.6mm, Dahua 4.0 Hikvision not mentioned.
Would a test using the same Lens yield different results?
