I have several 942l cameras on my local network running. Image quality was great using the app on an iPad at 480 resolution. Since a few days ago, the image quality has been bad and pixelated for 480. When switching to 240, the pixelation disappears, even though the resolution is lower. Has anybody noticed any differences recently? Information on the iPad shows that the 480 is in MJPG, while the 240 is in H264.
