Would anybody be interested in giving me a quote or just simply telling me the what the going price is currently for Dahua N42B2P2 (X4) and N45EM63..? Please and thank you.
No.
For Dahua, most buy from @EMPIRETECANDY and are getting international models with English firmware. If you do a search here for 'Review' in titles only, you will see numerous cams reviewed by members and not sure if any have been US models.
