Hello AJ, Good question! Ring battery products “see” the world through a network of three linked passive infrared (PIR) sensors. These are heat sensors that detect motion by monitoring heat within the detection area. Since people are hotter than the surrounding areas, as a person enters the detection area, the heat measurements change. The motion sensors register this change as movement and send out an alert. Windows generally block heat sources. Since the Ring device uses PIR (Passive Infrared) to detect motion, the Ring device will not be able to detect the motion very well through a window. For more information about motion detection please review this helpful article: https://support.ring.com/hc/en-us/articles/360022650691-Motion-Detection-in-Ring-Battery-Devices. For any additional questions or concerns, please feel free to reach out on our community forum at https://community.ring.com/. We look forward to hearing from you soon! Thank you, Alexis with Ring
Sorry, there was a problem. Please try again later.I actually tried using it though glass and it did not work for me. This was through a house window though. I’ve also read the the infrared night vision will not work through glass.
Sorry, there was a problem. Please try again later.It should work during the day, but if placed too close to the window it will reflect its image onto itself and it will look as if the camera was placed in front of a mirror. The foto provided shows the reflection of the camera facing out a window.
