I bought 5 Dahua Starlight Bullets IPC-HFW5231E-Z5 and the zoom is way to tight for my needs. 3 are unopened and 2 were opened long enough to put them up and see that the view is completely unusable before being taken down. They even still have the plastic cover over the lens. I'm hoping for $180-190 shipped as they're Brand new or nearly brand new. Contact me with questions.
