I have some experience with a few
We had an alarm.com system in Colorado that included one camera, it was an HD 720p camera. The picture quality was terrible, slow frame rate and very grainy. The alarm system was good, but if you're after good video, this doesn't have it. I should add that we had it installed in about 2014, so the quality may have improved since then. Alarm.com's phone app was solid, their control panel was good, it included two-way voice communications which is excellent for us with the kids. One positive for the camera system is that the motion detection worked well, and you can adjust the sensitivity.
I have ring doorbell, nothing fancy, but the picture quality is very good. The motion detection is good, and the app/web interface is good. I don't have experience with their other cameras, but I would imagine the technology is the same as in the door bells
I have an Arlo camera from their F&F program, several of us on the Nerdery have been able to participate in that. The camera quality is excellent, the one I have is a 4k model. The app and web interfaces aren't great, but they work. The motion detection isn't good IMO. I have it watching my driveway across to the front walk, when I adjust the sensitivity to capture people motion for the sidewalk, it's very sensitive up close, and will trigger too often. When I adjust the sensitivity down to avoid over captures up close, it can't detect people on the front walk. The nice thing about this model, is that it's completely wireless. Connects over wifi, and is battery powered. The battery looks to last about 60-80 days on a charge so far. That said, the price tag is too high IMO
I've been looking at redoing my home network using Ubiquiti products, which includes POE cameras. I don't have experience with these but I've heard good things.
