Will these work through glass? Trying to figure out how to trigger my Blink camera to start taping when there is motion outside the window…
No, PIR Motion sensors detect very small changes in infrared, infrared is blocked by glass, so none of these sensors work through glass.
To detect motion through glass, most people use a camera that does video analysis. ( usually called “pixel change analysis” in a home security context.) This works well, but is much more expensive.
The usual alternative is just to put a zone of motion sensors ( to reduce false alerts) outside.
Lots of detailed discussion in the following thread as people try to find the perfect cheap device, but to be honest there’s a lot of trial and error as different things work for different people.
I am looking for outdoor motion sensors to monitor my yard.
I bought a pair of the Aeon Labs Aeotec Z-Wave Multi-Sensor and am quite unhappy with them. Even on the lowest sensitivity setting it randomly sends alerts, some perhaps due to clouds changing the lighting (even though PIR is not supposed to be susceptible to this) and others I can’t explain at all. With several false alerts a day this thing is just useless. The Smartthings Motion sensor works great, I have some in my house, but it is indoor rated only. The Schlage / Nexia motion sensor is also indoor use only.
I am hoping someone has come across an outdoor rated motion sensor they have been able to pair with the Smartthings hub.
Mike Maxwell’s zone manager is an excellent smart app that lets you define a zone of multiple motion sensors, but then of course things get expensive as you are adding additional devices
I built this to solve a number of motion related issues.
–Reduction of false motion events in exterior applications (False Motion Reduction)
–Represent a group of detectors with a single virtual detector (Motion Aggregation)
–Enable a Motion Aggregation zone from various devices, switches, contacts ect (Triggered Activation)
This is a parent/child application (like Smart Lighting) where the motion zones are created and edited from the parent application.
When a new virtual zone is created, a virtual motion sensor is created for that zone. This virtual motion detector represents the states of the physical motion detectors that you configured for that zone.
You can then use that virtual zone device in any applications that accept motion devices.
BTW, i’m sure there are others, but the Arlo Q series (not the regular Arlo) can do pixel change analysis, so they can detect motion through window. I don’t know if these are part of the SmartThings integration, though.
You are the best for help…thank you!
