Equipment sensor: I have an expensive four-wheeler and zero-turn mower in my backyard, and would like to see some kind of sensor (other than motion, too many plants and wind won’t make it practical) to protect these expensive items as well. This would be a great selling point; maybe like a magnetic plug stuck to a metal part of the bike’s body, that if it’s removed from that metal body it alerts the brain.
It catches us leaving for work every day and coming home. It catches me when I go to fill the bird feeders. I’ve not had it miss any movement that I’m aware of. If you have motion sensors on, expect more notifications than you think you will get. As said, you’ll get the two from nightfall and sunrise. Plus I get two from me departing for work and my husband departing plus 2 more for each of us coming home. Add on more for checking the mail and anything you may do in the yard. This is where not being limited on storage size is handy. The cloud storage is $30 per year and it keeps videos for 6 months. It doesn’t say anything about size so having these extra videos doesn’t bother me. I find the video quality to be great and I can easily identify who is at the door night and day.
Update 1/24/16 - I have found a fantastic use for the Ring Doorbell and Chime. My mother-in-law, now in her 90s, lives by herself. She has become hard-of-hearing and often does not hear the doorbell. By installing the Ring on her door, she now is bothered much less (solicitors tend to recognize it and don't seem to like it) and when someone rings the bell, the Chime, placed by her favorite chair, gives her a better chance of hearing someone at the door.
