I have a few Hikvision DS-2CD2042WD-I bullet cameras which have always given me trouble, and I was hoping to replace them with Dahuas. I ordered an IPC-B5442E-ZE and was shocked at how huge it was when I opened the box. This would be way too conspicuous to have by my front door. Are there any good performing Dahua bullet cameras that are smaller? I noticed the 5442-ASE is a little smaller, but still quite a bit larger than my current Hikvisions.
