I just installed this today, so it's possible I could be disappointed later.I had a Skybell HD for years, but it was problematic from the beginning. Sometimes it didn't detect motion at all. It never detected motion until the person was already at the door, ringing the doorbell. It was frequently out of service, recently much more frequently. The biggest problem with Skybell is a serious design flaw. Power is connected to the baseplate, NOT to the camera. The camera gets its connection from contacts that are made when the housing is installed. So, it would often lose power when bumped (like when someone rang the doorbell!)So, I researched and settled on the Arlo. Basically, it was down to the Arlo and the Eufy, but the Eufy dropped out when I discovered that you have to install a doorbell chime (that comes with it) by plugging it into an outlet. There's nothing wrong with my existing doorbell, and the last thing I want is a bulky chime box taking up an outlet.Pros: Excellent video, alerts you to motion by calling your phone and then displays the video automatically (great feature), sound quality is more than adequate both at the doorbell and on the phone, has the ability to call 911, can detect animals, humans, vehicles, etc, the camera is wired directly to the system which (hopefully) means it will never lose power, motion detection is noticeably better than the Skybell. Objects are picked up about halfway up the sidewalk rather than when they step onto the porch.Cons: You have to pay a monthly fee ($2,99) to enable the most useful features. I don't like monthly fees, but $2.99/month isn't a huge amount to pay.Right now, I'm very satisfied. Installation was easy. We'll see if it holds up.
