Question: Is it only battery powered?  How many and what kind of batteries?  AC-adapter capable?
Document: This little thing is loud and very sensitive to motion. Great purchase for the money. I've been using for three months and still using original batteries.
I bought a single unit to experiment with it. It has a good range and sensitivity. Takes any type of AA batteries, indicates when they are low. The alarm is loud, but not extremely loud, which is exactly what I needed for my application. I will be buying 3-4 more.
If you are using it inside it should last a very long time. So it sounds like wind, rain and too much sun could ruin it. I find it very easy to remove from it's mount on the wall if I need to put new batteries in it. I think this is a wonderful and very useful little alarm and at a very reasonable price. This motion detector works really well for my needs. I am very pleased.
I purchased this passive infrared (IR) detector as a burglar alarm. This is a stand alone portable motion detector, with no need to purchase a separate receiving unit or any other equipment. Simple as pie really---put batteries in it, flip the switch to the on position, and it is ready to go.I have purchased portable motion detectors in the past, and found one of their problems to be false alarms.
I've bought many of these, I found them cheaper here! I care for seniors, I put one on the side of the stairs, so I know when my patient is escaping, I put another in the fridge, because she's a diabetic. I've used them in the bedroom, so I can assist my patient when she gets up, and in the bathroom. You could also use it as a burgular alarm. Great value for the money.
Yes this thing works like mad and it's heart attack city when it goes off. I use it to monitor the dog and other areas on the outside perimeter.
With the outside door open there was no point in running the wall unit either. Needless to say it got HOT out there during the summer time. I was searching for some way to notify me when Butler went to the door. I figured for this little bit of money, it was worth trying. It is amazing what a difference it has made overall. Now the outside door stays shut and the door into the house is also open which circulates air better.
The detector triggered when I walked by dressed in my warmest winter coat and winter pants. I was very impressed with the technology of this detector. Not too sensitive, nor too lacking in sensitivity. Having said that, I should state that I live alone with no pets.When the detector goes off in alarm mode, it makes a very shrill, ear-piercing sound. It hurts the ears.
Since I have it attached low by the door it is easy for me to switch it on or off when I need to be constantly moving in and out of the bathroom. I have the position for the real loud beep taped off so I won't accidentally set it to that as it would scare one because it is horribly loud. If one needed a real loud burglar alarm then the loud beep setting would be ideal for that.
Our 16 year old Sheltie lives in our attached and finished garage rooms. The slab and distance from the A/C unit means we needed an auxiliary unit put in through the back wall of hte house to assist in keeping it cool enough there. Butler's mind is not too good any more as he is near the end of his time. When he needs to go outside, he stands by the door going out back but makes no sound.
Answer: no
