I hope this is the relevant forum to ask this question, but I Googled and found a thread on these cameras back in August '17 by ni_hao which seemed to be resolved by Henrik.
I have 4 of these cameras connected to my wifi network, together with an 8 channel NVR similar to this: NVR
Since the cameras have their own local storage, I only use the NVR to view the cameras on TV via the HDMI output, or on my PC via the VideoMonitorClient.exe application. I also view the cameras on my iPad, Android phone and my wife’s iPhone using the V380 app.
Up until a few days ago, this setup was working well. However about a week ago I noticed red warnings in the iPad app to upgrade each of the camera’s firmware. I did this, initially for one of the cameras and it seemed to be OK, viewing the video on the iPad, although I had to reset the name and password on the camera. I then continued upgrading the firmware in another 2 of the cameras.
After I had updated the firmware in 3 of the 4 cameras I thought I had better check that the NVR was still connecting to the cameras and that’s when I realised that something had gone wrong.
The NVR only showed video from the remaining one camera that had not had the firmware update. The NVR finds all 4 cameras on the network using the Onvif protocol, but it won’t connect to the 3 that have been updated. They just briefly return a message “Connecting” which changes to “Offline”. I’ve checked that the NVR was using the correct login name and password for each camera, but it didn’t make any difference.
Comparing the firmware in the updated camera with the non-updated camera using the V380 app, I can see that the System App version has changed from:
The System Kernel and System Firmware are the same in all four cameras.
Does anyone have any suggestions how to:
a) revert the System App to the earlier version
or b) how to get the NVR to connect with the updated cameras?
