I had do the same thing… I was quite disappointed when seeing the corrosion considering these are outdoor cameras, but understandably, the connection point isn’t sealed.
I cut both ends, pinned out the wires and then matched them on the new cables and nothing seems to be working. Is there any way to check the camera to validate that something is fried?
I found one camera on eBay as a replacement for $65USD, but I’m reluctant to buy it considering I can buy a whole new kit for $350… So before I buy a new kit of the same brand, I’d rather confirm that the camera is fried by disassembling. But I want to be sure what to look for.
