Surprisingly silence. Well, I will share my own resolution. Here what I found and I guess also lost: Cameras from Vatilon, aka Huishi, super popular on Ali-express-baba, all suffering from the same problem: Most of the time some cameras serving still/JPEG of zero size. Unless your setup uses...

I have number of Vatilon's PB4 and H42 cameras deployed. Generally I'm happy with performance but there appeared to be some bugs: Loosing NTP settings, regularly drops to manual time settings and then displayed time will drift. When NTP set - it does sync as expected but usually after a few...
