I would love to see a dual sensor/lens/180 version of the IPC-T54IR-AS-S3/IPC-Color4M-T.
The current 180 models require visible LED or enough natural light to work; I don't like visible LED's and don't have enough light.
(Funnily enough; my T54IR camera's switch to B/W much sooner at the end of the day compared to my old 5231R-ZE, both with similar settings and placed on the same location)
