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

Also dahua are very helpful , do you not have access to there tech?

my first check would be connection or psu. Did u have connection issues with hik too?

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.

I was just looking for a quick reply over the weekend 

Could be a few things as above check the psu,bnc ends 

is it copper cable or the chepo stuff?

 

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.

thanks for your suggestions ElecTech, im sure its just an input set wrong but searching through all the menus i cant seem to find anything.

 

 

Try to set all inputs as CVI and see if anything changes.
