Hi there, please can you be of assistance? I am currently using a Swann DVR-4-Pro-Netâ„¢ 4-Channel Networking DVR to record footage abroad. The footage is recorded from 4 cameras and the image is split onto the screen in quadrants with each quadrant showing a different image. I have now taken the hard drive with these recordings back to my office in the UK and when I come to replay the footage in another Swann DVR-4-Pro-Netâ„¢ (exactly the same model), I can only replay the recording from one of the cameras. The quadrants just split the image from camera 1, rather than showing the images of cameras 1, 2, 3 and 4 in each. Please can anyone offer some advice on how I can set the system up so when I replay the footage, it plays out with all 4 cameras as opposed to just one? Kind regards
