Ring Doorbell Pro Image hazy/blurry

My Ring video Doorbell Pro's image has deteriorated so much that it's impossible to recognize the person outside. Image is blurry. It is about 5 yrs old and had paid over $250 for it when I bought it. I called Ring Support and was told that the best they could do is send me a 35% off coupon! I have been loyal to the Ring product-line and over the last few years added more cameras and even their Alarm system, having spent well over $1000 . But if I have to replace their Cameras every 5 years, I am not so sure that I should be buying Ring products any more. Heck, my previous hardwired Alarm system lasted over 20 years.
