Full disclosure, the seller offers a small gift in return for an Amazon review, but I review most of the Amazon things that I buy and would have given the same grade regardless. The bottom line for function and picture quality it's amazingly good! The tech has come a long way in the past few years. It can't compare with the resolution seen on a big screen desktop monitor from my my wired POE security 4k cam system, but looking at the the feed from your phone screen it's pretty incredible and the 2 way audio is actually better than my wired system- been surprisingly good too. I have mine set up to keep an eye on a turtle in a 125 gallon backyard pond which is about a 100' from my google mesh router, only takes a second or two to connect; The default settings for daylight are excellent; have not tested the reach at night but in the 10-15' range for my use, the PIR view for brightness-contrast and sharpness is super. I was already was a user of the cloud edge app for a door camera, so setting that up was a snap and easy sharing the feed with my wife's phone too. For the first four days I didn't install the solar panel let it run on battery and I don't think I lost any bars. When I did install the solar panel it charged it in about 20 minutes to 100% and it's been on full ever since. Not really a con but a bit wider view would have been nice. Maybe my next one will be a PTZ version. So far I'm very very happy - this has been a great buy, outside in the rain and Hawaiian sun for close to a month without a glitch.
