I need another varifocal camera for one side of our home. I have a IPC-B5442E-Z4E on the other side and it works reasonably well. For that camera I have Day & Night on Auto for both Day and Night and it never goes into B&W. The other side (the one I need a camera for) has less light so I suspect it will go into B&W. I am looking for something at least as good as the 5442E-Z4E with varifocal lens (it will probably be around 16-24mm, I think). I did see a 8MP version but with the same sensor size so I don't think I will gain much from that. It's just for motion detection and recording faces. Are there any other recommended cams besides the IPC-B5442E-Z4E for this kind of situation?
