The keypad has 12 backlit buttons on the left-hand side and three in a circle on the right. You create a four-digit PIN during setup, which you’ll tap into the keypad when you arm and disarm the system (you can also do this from the Ring app, which is available for Android and iOS devices. It’s the same app used for Ring’s video doorbell and security cameras, although there’s currently little integration between the cameras and the security system.)
I installed a motion sensor inside a shed in my backyard (shed has a tin metal roof) and I kept getting a false alarm daily usually around 1 or 2pm; Ring informed me that their motion sensors use infrared technology and that excessive heat could cause a false trigger. They told me a contact sensor at the shed’s door should do the job and that’s what I will be doing next.
3 - If you do not answer the alert fast enough, you are locked out-- even though someone is standing at your front door. You cannot "turn on" the camera from your phone or tablet. If someone is there and you do not have an "ACCEPT" button on the screen, there is just no way to see or talk to them. This is obviously a software flaw. You should always be able to "wake" a camera remotely and talk to a person at your front door. Or maybe you just want to see the view outside your front door. You should be able to access the camera / microphone and enjoy your front yard.
