I bought a 16-port 8-camera 3TB Ezviz system "open box" (at a significant discount.) Upon arrival it looked like the box had never been opened. Cameras were sealed, NVR was sealed, cables were sealed. I tested indoors to make sure everything worked before installing the cameras. Once the cameras were installed it worked flawlessly, for a couple of days. Then I got a notification in the app that a camera was down, followed by another, and another, and another until they were all offline. The NVR ports were all unlit. I unplugged the power and plugged it back in -- still no lights on the switch ports. I called Ezviz tech support, who had me factory reset, then upgrade firmware on the NVR, then factory reset again. After that didn't help, Ezviz started RMA and then informed me that I had purchased from an unauthorized reseller so there was no warranty. I could return the entire system, but since I got it at a discounted price, and having spent many hours running cables to 8 cameras, I would rather try to resolve this... even if that means a camera is bad, the NVR is bad, or cable is bad.
So anyway, later that day I tried powering up the NVR with no cameras connected. Then I plugged in one camera, and VOILA, the port lit up! I connected another, and that port lit up. I found it would work if I plugged in the cables one at a time until all were working. Since then it's went down a couple more times, randomly, and plugging the cables in one at a time has fixed it. Until today... they all went down, and when I started plugging them back in again, they were working until I plugged in one particular camera, then ALL switch port lights went off immediately. I tried plugging that camera into a different port, and also tried a different ethernet cable to that camera, same thing each time -- plugging that camera in shuts down all the ports immediately.
I'm baffled as to whether this is a camera problem or an NVR problem. Any ideas?
