Problem after installing Firmware 2.0.4 on the C340-W 2.20
After the notification on my NVR VIGI 1004h-4P, I updated the firmware of my C340-W 2.20 camera to the new version 2.0.4 Build 241216 Rel.43399n (before I was using 2.0.3 Build 240914). Everything went well, but soon after I started noticing some graininess and strange artifacts in a certain area of the image when the camera is in Infrared mode. In color mode, it seems to be normal, or at least I can't notice any difference.
Should I reinstall the previous firmware? Won't doing so affect the product warranty?
I also have a C540-W 2.0 and I did the same update to version 2.0.3 Build 241216 Rel.51462n, however, I did not have the problem mentioned above, but rather a noticeable improvement in the ability to detect humans.
Since it is difficult to show this problem through an image, I recorded a section in which this occurs (it becomes evident around 15 sec in):
