Ragmin 0 Posted August 21, 2018 I just purchased three of these cameras and cannot get them to power up, I 'm giving them 24 volt a/c and have tried two of them but with no results. It's states the following: power supply : 12 vdc±15% 24 vac±15% power consumption. I'm thinking about just trying 12vdc to see if this would work, any thoughts on this option before I try this. I also contacted an spoke with Hikvision technical support yesterday and they said that it should work and I should try another camera. I did with no success. When I put my volt meter on my source I was reading a little higher then 24 volts but with in the 15% of the manufacturing requirement, does this matter? Any help would be greatly appreciated Thank you Share this post Link to post Share on other sites
