Real-Time Notifications
-
Simple Setup and Simple App Connection
-
Uses three replaceable AA Batteries

Next, separate the top with a iFixit Opening Tool to get access to the electronics inside.
-
There are number of catches around the outside of the device. These catches popped loose fairly easily with the iFixit Opening Tool.
-
Once the top is removed, we get our first look at the internal PCB

-
Close up view of the back side of the battery compartment that also supports the internal PCB
-
Power from the batteries is passed to the PCB via metal tabs
-
Tab on the enclosure interfaces to the slide switch on the PCB to cut power when the bottom of the enclosure is rotated to access the batteries
-
Battery Mating Connectors for the battery compartment metal tabs . The non-forced connectors allow for easy removal of the PCB from the enclosure

Switch/button operation is not documented
-
Power Shutoff Switch. When the bottom is rotated to access the batteries - this switch slides as the enclosure bottom is rotated to shutoff battery power to the PCB

Neat! Given that it uses a microphone, I wonder if playing the sound of breaking glass over a pair of speakers would accidentally set it off.
Yes it would. That is probably how it is tested.
No, it doesn't. Many people have tried but it's now a well-known fact in the Ring Community that the sensor can't be tested using this method. The agreed method is to carefully break a glass or a bottle in its vicinity which does set the alarm off.
My basement windows are on the ground level, where an intruder could easily kick them in, so I decided to install the Glass Break Sensor there. Just in case, I installed a Ring Z-Wave Range Extender. I brought a couple of empty bottles, slope game a medium-sized pickle jar (also empty), and a large rock from my yard down into the basement because I didn't want to sacrifice any of my actual windows.
Sometimes tossing a keyring full of keys in the air and catching them in your hand is enough to set of a glass break sensor for a test.
