Are you using it just to alert you, or for evidence? Do you want it to be hidden or obvious?
I have a couple of these solar powered security cams. The one out front is set super sensitive, so I have a 5V supply connected to it too. The one out back gets triggered less frequently, so solar and the built in battery is good enough.
I don't use the alerts, but it is supported. What you may like is that it has a mic and speaker, so when you get alerted, you can press the mic icon and yell
"hey man, pick up your dog sh*t !!!" and embarrass the f out of them too. Or, you can push a button on the app and the camera will make a loud alarm sound, but that may result in the owner crapping himself too.
I think it's also a visual deterrent since I have very few, almost no, issues now, and there are a LOT of dogwalkers on my block.
PS. I just tested the notification and it made a ding on my phone and displayed a link that brought up the camera footage.. I use the free registration which provides a limited amount of online storage, so I have a micro SD in the unit that captures tons of footage before it starts overwriting anything. I got them on an Amazon sale, 2 for $80.
PPS. Check out the review where the neighborhood kids stole the camera, but it was still working off battery. The owner showed the cops, with the kids talking into the camera laughing, so the cop and owner headed over. They denied it until the cop said he just watched them live on camera. LOL.
