Will this unit allow sensing through window glass i.e. I want to mount this inside to detect motion in area outside window..

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.

There is a sensitivity sitting...when we 1st installed ours it would flip the light on when a car would turn the corner in front of our house because the headlights would shine in. The window is a privacy window..distorted not like a clear window. If your window is clear and the motion sensor/switch is pointed at the window I would think it would work but if it's dark out which is probably why you want it then it may not "see" the movement to flip on. I use it in my front entry (with privacy glass beside the door)and it doesn't come on until I open the door.

No. Glass will mask the motion as much as a wall. I tried it through my French door.

This product works using a sonar principle to detect motion. It will not work through 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.

Hey Ben, i put this unit in my hallway and i gotto say its pretty sensitive. I actually had to put a matte scotch tape over it because the light would turn on every time i would get up off my couch. I can't really say that it would work behind glass but i dont see why it wouldnt. Cheers

If your only goal is to get a better signal by placing this in the window as opposed to next to you, that should work. This product is not an upgrade over internal GPS chips in most of the high end devices.

It mounts flat to the SIDE of something like a wall or the exterior side of an eave. It is not meant to be hung either upside down or from a celing. I am sure it would still work, but my concern would be the sensor would be pointing straight down. You would have to be underneath it for the sensor to kick on.

The camera is powered by a standard outlet. I am not sure if the camera can be triggered on by motion detection. We use it for a continuous live feed. It should work installed behind a glass window. You just might need to make sure to keep the glass clean for a clear image.

I don't think the motion detector would have much reception at that angle. You could fasten a board across the angle and mount it level. It would probably be worth the trouble to get it level and working right.

I don't see any screw holes on either the Motion Sensor or the Entry Sensor, and regardless, they won't do any good for a metal window frame. I had to rig the latter to ensure that it would stay in place. No tape is dependable on a cold metal window frame.

I previously answered yes by mistake. The outside motion detector flashes but not the inside monitor.

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.

You might have motion detection issues if the lamp is behind a white-frosted glass cover, but I have no way of testing. I mounted mine in a recessed can-style porch fixture though, by using an adapter - the kind that adds two outlets to a light socket, with a chain pull switch (which I leave on for this application).

Camera Based Motion detection has always been problematic. the best ones let you set specific areas to monitor (like your desk rather that your whole office, or the gate and doorway rather that the whole back yard, etc). I haven't bought this one yet so I don't know if that feature is offered, but it is pretty standard.

Possible. This motion sensor can only see about 30 feet if you point it down. Point it up and the wind will set it off. This means the sensor is close and receiver has a short radio wire on it which could possibly receive a sensor signal from a long distance.

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.

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

I'm not sure what you are asking. I have an old hard-wired alarm system and I replaced some windows in my house and used these glassbreak detectors on them. From what I understand wireless systems are now the norm and these detectors won't work for them.

No. This unit is designed for outside. It would be too sensitive for indoor use

This device would not work through a lamp shade if the shade is between the motion to be detected and the sensor lens. The sensor reacts to changes in heat in the sectors of the area it is sensing. I cannot envision what material a lamp shade would have to be made of for a heat signature to penetrate it. So, if you cannot see the black band around this device from where the motion would occur it won't work; and the motion has to involve something emitting heat, which lots of clothing does not do - so check for a large area of bare skin to be where the band can "see" it. I can, for example, "hide" from my sensors by wearing a hoodie or winter jacket with the hood up and turning my face away from the sensor. By the way, some such sensors can "see" through a single layer of a black plastic garbage bag, but I do not think this sensor would reliably do that.

Not sure...but as a suggestion your wasting your money if using it as a door sensor...
