This guide will help you fix the issue that can arise for customers with the 4 and 8 camera 4 megapixel NVRs from Xvision where the cameras are set up and connected but the image is blank.
This is caused by the 4 and 8 camera NVR being programmed the same way as the 16 and 32 camera versions of the NVR. The 16 and 32 camera versions use H265 video compression whereas the 4 and 8 channel NVR use H264.
So all you need to do is change the setting from H265 to H264 on both Mainstream and Substream and its done…
Go to the main menu then select RECORD
Now select MAINSTREAM and select the camera number that has a black screen and change the BITRATE CONTROL setting to H264 and then SAVE.
Next select SUBSTREAM and do the same again, and SAVE
After a few moments the camera picture should appear.
Now do the same with any other cameras with the same issue.
I hope that helps, please give the office a call if you have any questions about this article.
