Hi! I'm new at this so please help me get going! I'm posting what I bought, then asking questions, o.k.? here goes, GVI Multiplexer QUAD PROCESSOR 4Ch Color CCTV POWER SECURITY CAMERA SURVEILLANCE @ Ebay I paid $40.00 . I bought that and 4 SECURITY CAMERAs . POWER SUPPLY SURVEILLANCE BOARD CCTV CO...The cameras have a place to plug in small 4 pin somethings? 12v DC and 24 v A/C power supply. The Quad processon has a 9 pin receptacle for an alarm, but I don't know what type? It's a used unit but it works! I plugged in my 4 cameras and all work great! Cameras have 2 BNC outlets and One is for a camera and one for loop. What is the loop for? It also has a 4 pin receptacle and 2 small on off switches. It has no instructions but maybe you all can help me understand it? I boughht a bunch of cables.How would I know if it has a motion detectable? thanks,,Ray.
