alquizard 0 Posted July 12, 2016 Hi good morning, i need help on my DVR. I attached the screenshot. When i open my DVR even without camera connected this is the result, when i connect the camera, the display of channel becomes wavy and turns the color to black and white display. What should be the problem? Thanks a lot. Share this post Link to post Share on other sites
karenbigbro2 0 Posted July 19, 2016 Have you checked your Power Supply. Looks like you have very little power getting to the DVR. Check to see if the light on the power pack is flashing - if so purchase another. YOu will need 5A 12V at least for the number of cameras that you have.
