the first part of image is ok, and the second part seems like strips.
Can someone suggest me how to improve the image quality or how to solve this problem?
Oooookkk, so the raspberry is not enought strong.
I’am building a new house all domotic with all light with sonoff relay, alarm, cameras and automation. So I thing the raspberry is not enought, or is not safe stable for all this device. Maybe I have to use a old pc or old server to run HA. With ubuntu or maybe virtual enviroment in FreeNAS. It’s possible?
Look at passmark score for CPU >2000 is enough
Same spec as Plex server recommendation. You may get the tearing image due to poor networkperformane of camera also so consider that
Also, your cameras may provide camera jpeg through direct link. You can use that and avoid performance issue on RasPi
