Rock 0 Posted February 24, 2022 Hi, Our Jooan 4 cam NVR HD 3MP just stopped working. It has been fine but not now. I have opened it up and the little green light on the mobo works when I plug it in, so the power is getting to it. The battery should be okay as it is only 8 months new. Any ideas please? Is there a way to test ? Thanks oz Share this post Link to post Share on other sites
