Poor image quality of stick-up plug in camera

Just purchased and installed a Ring Stick-up Plug In camera. A little disappointed in image quality along the periphery of the image which is fuzzy and poor color rendition. Is this normal. It’s not a problem with my other 3 cameras. See attached image file.

Does anyone have troubles with getting there indoor camera to work again. I tried deleting the app. Re setting everything and try to connect both my cameras and I cannot get them to work or get the WiFi to work with it as well?
