Hi,
I just bought two identical cameras from an outlet in Shenzhen. They have BNC video output plug and were both tested at point of sale. I saw them working. After I return to Australia and plug them in, there is no output from either camera. I have tried plugging them directly into TV, through my DVR and through a video to VGA converter to a monitor. It states they use 0.5 Amps (12v). I was using a 2 Amp (12v) power supply. The IR's come on when you cover the light sensor.
I have heard of cameras that only work in China, but I believe that to be IP cameras.
I bought two other different style cameras from a different store and they work as intended.
I was wondering if anyone had any ideas what the problem could be. Surely both wouldn't be damaged in transit in the same way as each other.
