tuisce

Hi, I have 4 Cameras on an 8 CH DVR, no run further than 100 feet on 5e cable, baluns on both ends, powered on a 9 way 12V - 10A Power Supply. The video feed has just stopped, no intermittent problems, there is no warning message on screen from DVR about video loss, the IR lights are still on at night so I don't think its a power supply issue. Any Ideas, any help greatly appreciated. Thanks
