We have a strange guy walking back-and-forth in front of our house. When I take a screenshot of the video of the guy and try to zoom in the face is very grainy. You can’t tell any facial features enough to put on the Internet to a local community blog for people to try and recognize the person. Is there a better quality camera? It doesn’t have to be wise. It could be any other manufacturer.
First thing to check is make sure your Cam v3 is set to HD (the highest v3 quality) and not SD or 360p. I am using an older Wyze App so your App may look different.
Also, try to zoom in on the strange guy if he pauses for a moment. I get lots of v3 blur when zooming in on a moving subject.
You need a camera with Optical Zoom not Digital Zoom. I’m sure the #1 Reolink fan @bryonhu can tell you which cam is best suited for your use. Get your wallet out. 
Or an OG-Tele.
25 feet is pushing it considering the extremely high compression ratio these cams use. If the person was standing still it would probably be a usable picture, but if they’re moving it will be blurry. If it is night/low light, even worse.
