I want this to repel human night visitors who intrude--would it work for that?

Didn't work for me at all. Squirrels loved it. The sound annoyed me more than them.

I don't think it would work for human intruders since they are unable to hear the high pitch sounds emitted by this device nor would they be scared off with the strobe lights.

I doubt this would be good for keeping strangers out. It might be a BIT of a deterrent, but would probably be broken through easily if they really wanted to get in. It's much better for keeping your kids from opening doors they shouldn't. Hope this helps!

I think that might work. It would stop the sound once closed. A motion detector might also work. This brand works great.

Yes & yes. We had a problem with new neighbors and they kept letting their dogs bark between our houses when they tether them outside. After asking nicely, and it turning into a battle, I bought these to deter them from putting their dogs on our side of their yard. No more barking dogs! (They rent and they know I have complained to their landlord, so if they think we have something on tape, & it stops the barking, all the better)! The blinking light light can be seen easily at night to deter anyone from your home/office.

There are motion sensitive kids' toys which attach to doorknobs which might work better. Sometimes billed as "spy" toys, I think they hang. It would probably go off every time you brush against the shade, though that may not be an issue for you. Check out the Spy Net: Motion Activated Micro Alarm.

Absolutely. We used it to monitor my Mom's hospital bed. Dad's was right next to hers and it only alarmed when she got up. My Mom is deceased do now we use it for exactly the application you asked about. We keep it on a bar by the front door. It alarms if Dad crosses it to the door, but not while the rest of us walk around the room. Just direct the beam to the area you need as though there is a string from the device to a point across the room. This thing is very much worth the money!

Yes! The noise this Sentinel makes will scare off animals! Place it where the plants are, pointing it forward to detect any animals.

I believe so. We have it mounted on a jail transport van, and it is loud enough to warn pedestrians, but not so loud to wake up the neighborhood at night.

Check the laws in your state. Now if you are asking if it would be effective against intruders in your home, in my humble opinion, it would doubtlessly be effective against intruders. It'll flat mess them up while you run and call for help.

I'm not sure because i've online used it at night! But I don't believe it works well for that.

I think it'd work pretty well - it's pretty opaque. They may be able to see your silhouette but that's all.

I never would have thought of that use!! I guess you could, it is loud enough to scare them away! It would have to be enclosed I would think so it does not get any moisture in it. I am interested to know if it works!!

I am not sure that would work. I think this device uses temperature changes to detect movement. For example, I have this right next to my front door. If I open the door (and it opens into the sensor) nothing happens, as soon as my body is clear from the door then the device detects something. Perhaps something using the contact closure module will be more effective.

No, it won't illuminate the room itself, but it would probably make anything that is backlight reactive glow a bit--and the closer those things are to the light fixture, the brighter and more intense they will be. It will provide some room light, but not enough to keep guests from tripping over one another.

Yes absolutely! Just make sure you keep it away from their face and bottoms per the directions.

Probably not. I got it to try and keep skunks raccoons, possums, and cats away, they are still coming around. Wish I could find something to keep them away

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".
