Dear All,
I have got a cctv system installed with 5 cameras. They were working well till recently. But the other day when checking the screen I could see only flashing blue video loss message on all five channels. (sorry if it is not clear, English is not my native language, and I am bad with technical terms anyway)
It happened from one day to the other, checking it around midnight it was ok next morning it was not. Behind the blue screens originally I could see the camera view for milliseconds. But I made the mistake to press the power button, and since than only black image appears for those ticks behind the blue video loss message.
Any advice would be appreciated.
