Hi. I have a cctv system with 4 cameras. A switching adaptor input 100 240 50/60 hz
output 12v 1000ma powers the 4 cameras through a 1 to 4 splitter cable reads 13.1v at the adaptor side.
The cctv unit has the same 2nd adaptor but has 2000ma instead. it reads 12.5v output (multimeter dc)
The problem is the cameras using the 1000ma adaptor has no inferred at night. But if I start to unplug 1 camera at a time from the splitter, the inferred returns gradually with every camera I unplug.
Again this adaptor via a multimeter is outputting 13.1 v. Is the adapter knackered or is it OK?
The splitter is OK as I bought another and its the same.
Can I swap around the adapters to test is the 1000ma 1 is no good. Will the 2000ma damage the camers or will the 1000ma not be good enough to power the ccvt unit.
Why would unplugging a camera from the splitter start to light up the inferred bulbs in the other cameras. And why is it gradual until 1 camera is left plugged in. (Doesn't matter what order I remove or which camera I remove from the splitter first.
