RING 4 — reduce issues

This sounds weird ..Ok so right now I live in an apt with lighting and sometimes I get weird lines; when I adjust the HDR it helps but it’s like have to do it once a day ,So my questions here is what I am talking about (pictures of it looking crappy and not )So my question is do they maybe make protective film to go over to prevent this or what does someone suggest ??! I can’t put it on the wall (using screws) and afraid of using adhesive tape because u never know someone might steal it..My rssi has been between 30-60 (have a eero router with one of the routers near the doorbell on top of my pantry —- and having it changed doesn’t effect this issue?In general is there ever away to make it 100% perfect or does everyone have some issues ??
