DAHUA ptz sd49225T-HN 2MP 25X Starlight IR network dome. Worked well for one year and one month. Just long enough to get out of warranty. Will not talk to software. It will make the 360 turn in attempt to initialize but can not be located on system. Dahua search tool will not find it. PSS will not find it. I will give it to first person who lets me know they want it. YOU PAY shipping to you by whatever shipper you choose. Email me @ firstname.lastname@example.org first come first take.
