Greetings all! I have an older 12" Lorex B&W 4 cam system with audio & PIR sensors on each camera. My monitor just died & I haven't found a replacement yet, in the meantime I have a 14" color system with built in time lapse VCR that I have hooked B&W camera's to. The B&W monitor had a built in alarm feature that utilized one of the pins in the 6 pin din cable, but it looks like color monitor only has external (screw panel) connections for alarm/pir? My question is, which pin/what color wire runs from the pir's on top of the cameras so I can pull them out & connect to screw terminals to get alarm notification on the color monitor? Thanks
