A likely power surge that disabled the cameras because the technician did not connect the power cables individually to the correct part of the power supply instead connected all cameras together at the power pack output terminals. Can the cameras be saved?
Hi @nedtech, Have you measured the output voltage of the power pack? A power surge may have only affected the power pack and not the cameras. Does the power pack have separate outputs or only the one? If the cameras were all connected together at the one output i.e. all +ve together and all -ve together, they are connected in parallel, so the voltage level would be correct for each of the cameras and it would then depend if the power pack could provide enough current to run each of the cameras simultaneously, which presumably it did OK before. What is the make and model number of the power pack?
