I ordered two of these in the 6mm variety on August 12th and they were delivered today: http://www.aliexpress.com/item/Dahu...ecurity-cctv-DH-IPC-HDW4421C/32397210988.html
This camera is 3-axis adjustable.
I would have been happier with an 8-10mm lens for this, but 6mm was the narrowest available. These are replacing years-old 5MP cameras from a small-ish Chinese vendor. They had 8mm lenses and were great for capturing fine details, day and night. Honestly, they had the best night vision image quality of any security camera I have yet owned. But they were exhibiting extensive video corruption ever since they were new and this summer it got really bad so it was time to replace them.
As usual, I will jump straight to image and video samples. I have both cameras mounted in their permanent locations. Night images and videos will come later.

Here is a video of a vehicle driving past the camera, captured with Blue Iris using direct to disc. The camera was set to 2560x1440 (maximum resolution), 20 FPS, 10 Mbps, and CBR (constant bit rate) encoding. I learned with my earlier Dahua 4mp that VBR (Variable bit rate) encoding produces much inferior results, so I will only be using CBR with these cameras.
Night pics
These are not lit solely by the cameras. Additional infrared is present from other cameras and a spotlight illuminator.

Night videos
2560x1440, 6 FPS, 12 Iframe interval, H264+, CBR, 8 Mbps
Here are some pictures of the cameras. In their normal orientation, the ambient light sensor is at the bottom of the face, and the lens is on the right. IR LED on the left.
