We are using 2 of these cameras 6MP WDR 2.8mm in production under a parcel sorting machine and we are very happy with them.
Considering Arecont previous issues with multi images which we also experienced these cameras work just fine, no resets and no color filters block.
We experimented a lot with the blind spot and found out that if you rotate them in 90 and 270 degrees angles so that horizontal pixels become vertical and vice-versa the cameras will overlap a little bit and there will be no blind spot underneath. The cameras are mounted at approx 2m height.The colors quality depends on the setting indoor/outdoor/mixed mode.
For us this type of camera brings cost saving in terms of Milestone licenses and is a little bit cheaper than 2 Hikvision 3MP cameras + 2 licenses + 2 x cabling + 2 x switch ports + 2x installation cost. In the long run saving is increasing with Milestone annual support for only 1 license.
Hope this helps.
