Does it work through glass (windows or doors)?

Sorry, I'm not sure. I've not had to try. I only use mine inside with a clear line of sight.

You can run it through a window with a screen but you have to adjust the screen to the new smaller opening size. I have my unit vented out a screen door and had to purchase a window extension to make that work.

You install it onto glass by double sided square stick one. It is powered by your security control system. It does not work by itself.

I used the product on a garage door and it does help. It might work better on glass but won't look very good.

I just figured out I did not answer your question. I have not tried it from inside a building while my camera is outside? I figure it would work through a window? Sorry for the useless response.

Interesting. I never tried one inside glass. Cannot see any reason it would not work since it views optical. I have some outside but under a roof. I have a wireless one taped to a tree in front of the house. It tells me when the mail goes.

Yes, if your doors are glass and not plastic. The company specifically recommends it on their website.

Yes...it will not work through walls. Anything will impede that range such as being in a pocketbook, in a drawer, etc.

The transmitter does work thru windows. My transmitter is mounted on a tree next to my driveway, about 100 feet from the house. The receiver is on a table in my living room. See my review for solving false alarms.

It should work on any type of smooth glass used in any kind of Windows. It relies on surface tension so it might not work on glass with a rough texture texture privacy glass like you might find in a bathroom or on a shower door. It goes on the inside window pane so single or double pane makes no difference.

It works fine for us through a car window. We also use one at home through old thick glass and it works fine. We live in a VERY rural area and need it. I'd buy it again.

It will work through walls and ceilings. But it does not perform at a long range, despite its claim. It may have something to do with interference from what is behind the walls or ceilings. Mine works perfectly to turn on electric from approx. 25 ft to 40 ft. But, it will not turn off unless it is within 15 ft. Why? I cannot explain.

It will not go through glass. It detects movement and body heat to activate.

No way can this go through a glass door.The frame of the pet door is only thin enough to hold on screen.Going through screen was easy -required cutters.

I have used this while my dog was outside and I was inside with the front door closed and she stopped what she was doing and turned to look at me so I do believe it works through a wall/door (possibly through 2 layers of wall/door).

It is a glassbreak sensor and not a vibration sensor so it works by detecting sound and compares it to a digital representation of what breaking glass should sound like. Some glass break sensors do not work for saftey glass (like the glass in sliding doors) and some do. The manufacturer or maybe this reseller would know.

It may reflect a glare from the glass or light entering window. Easiest way to do is mount it and check on it throughout day. One thing, it goes through the batteries and delay misses some action.
