Itsadubthing Posted June 3, 2017 Posted June 3, 2017 Hi All, Just looking for a bit of advice. We have been using the Hik-Vision stuff for a while, but due to the current issues with the new Hik we decided to try out the Dahua HDCVI stuff. I installed a DHI-XVR5104HS with some DH-HAC-HDW2401EMP cameras. The problem I am having is when I plug them into the HDCVI BNC the camera is not stable and only comes on crackling and black& white. im sure this is just a setting but I cant seem to find anything about it anywhere. Please can you help Thanks C Quote

james.wilson Posted June 3, 2017 Posted June 3, 2017 my first check would be connection or psu. Did u have connection issues with hik too? Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
Itsadubthing Posted June 4, 2017 Author Posted June 4, 2017 (edited) no never, and when i swap the bnc to the analogue end the picture is fine (low quality but fine) my first though was my BNC's. Its a brand new 2Ah psu but again I have tried another one also. 11 hours ago, Lwillis said: How are they wired? Cat5 with balauns or shotgun? shot gun cable Edited June 4, 2017 by Itsadubthing Quote

Lwillis Posted June 4, 2017 Posted June 4, 2017 Could be a few things as above check the psu,bnc ends is it copper cable or the chepo stuff? Quote
ElecTech Posted June 4, 2017 Posted June 4, 2017 (edited) Seen something similar before. The camera has two outputs... HD-CVI and CVBS, looks like your in the opposite one to what the input is set as. Switch it and see what you get. *just saw the above post and you already have done. Check the input is set to HD-CVI and not analogue within the DVR settings. Can't remember where in the menu but can check one later if your struggling. Edited June 4, 2017 by ElecTech Quote

ElecTech Posted June 4, 2017 Posted June 4, 2017 Try to set all inputs as CVI and see if anything changes. Quote
