will the senser work through black glass?

Black Glass? Most tanks just have a black film on the back that can be scraped off. So to answer your question: No. The sensor has to "see" the sensor on the other side of the glass.

No, both parts need to see each other, they don't need addition light it produces its own. So the device can operate in darkness. But I reitorate both pieces need to see each other. Eben algae can interunp this process

I have no idea but I don't know why not, for I'm not sure if it would even turn on the sensor. Try it and let me know

Hey, you should remember that painting the sensors will interfere with its ability to detect any objects since the sensing waves will have to pass through the paint also. Note I feel certain that there are colored sensors available.

Nope. Any motion sensing would have to be done in the software. Most modern systems do it this way, these days. Keeps the cost down on the camera, anyway.

Have you tried testing it with the sensitivity turned all the way to high? If it still doesn't sense movement with the sensitivity set to high, then it is probably defective. I have two of them and they sense movement through stucco with the sensitivity set to less than 1/3 the way to high. Glass is nothing. We had one that I bought that was doing exactly the same thing as your's as soon as I bought it, wouldn't sense movement through anything, even with the sensitivity set to high, but would sense movement inside the house. It was obviously defective so I replaced it.

I'm not sure if different types of glass affect the sensitivity differently. I put one of these in my laundry room and we have glass doors on our washer & dryer where you can see the laundry tumbling and they do NOT trigger the lights. The laundry inside the drum is also not lit so it's pretty dark on the other side of the glass. I have not tested to see if turning those lights on will trigger the sensor because I was hoping that the light didn't come on because of my washer & dryer.

I don't believe so. But what I did find is if I took the scanner apart, and cleaned the glass, it worked fine.

No I don't believe it will work that way. The light will be dim, and go brighter when motion is detected. I don't believe you can cover up the motion sensor without also covering up the Day/Night sensor as well, as it's all behind the same sensor "window".

Yes but it cannot be behind glass as it is motion sensitive and will not detect movement thru the glass.

I don't know about that situation, however it is very sensitive and should detect sense that unless the sensor is infrared and may be reflected.

I tried that and found it would work as long as the lights in the room were off, the infrared for night vision reflects off the glass so no tru night vision.

Yes. I had no issues connecting these to my Smart Things hub. I simply went to the add device screen, and pulled the plastic tab on the back of the sensor, waited a few seconds, and it appeared under &lt;Other Devices&gt; as a Z-Wave Door/Window Sensor.

It should work, see below and try different application. Some of them require a pro version to connect with the sensor. Other option for you to check youtube.http://www.zephyranywhere.com/apps/

I doubt if any IR sensor will work behind glass, frosted or not. The glass itself will put a consistent temperature right in front of the sensor and anyone moving across the room is not going to change the temperature of that glass cover.

The other answer is just wrong. He only has the illusion of it working some of the time. The fact is motion sensors (of this type) do not function through glass.

No it does not. I installed in a large glass fixture and it could not see through the glass. I moved the sensor outside the glass and kept tweaking the sensitivity, but was never able to get it to work correctly. The whole thing is sitting in my garage and I am now installing insteon switches.

Yes sure. Just put down the sensor a little bit, and it catch it. The sensor es very sensitive.
