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
