Driveway Alarms Wireless Outside Weatherproof - Motion Sensor Alarms System Motion Detector Plug-in Receiver Loud Chimes Security Alert Monitor System 500FT Long Range Outdoor Detection

I upgraded to these waterproof outdoor sensors + alarm unit + I am happy I did. My last system did not survive 2 winter's rains. These are really well-made + they seal up nicely once u put the batteries in. You'll need a Phillips head screwdriver to install the batteries in the sensors. Sensors can angle up or down + left + right to suit your needs. They come with strips of "de-sensitizing" tape that u can place on top of the sensor area to reduce sensitivity to motion to reduce unwanted triggering. For instance, I have 1 facing a covered fence that people walk by but I only want the sensor to trigger when someone walks right in front of it so I put a strip of this tape on it. Now it only triggers close-by motion + doesn't pick up the far away motion. Avoid putting it behind branches + leaves that move around! Plug-in alarm unit simply plugs in + it pairs up instantly with the sensors without having to do anything. Nice + easy. Volume starts at medium out of the box + can be adjusted from there. Lots of alarm tones to pick from. Works great so far. Has withstood the rains thus far + triggers reliably. Has already paid off alerting me to an intruder on my patio! And with that, it has paid for itself as I live alone in the city. You just can't be too safe. Recommended!Water

Works as expected. Tons of options for chimes / alarms (almost too many), Sounds are loud but a bit shrill but they are noticeable, easy instructions, distance worked for me, came with batteries, has good visibility / detection without too many notifications, price was just right - looks fairly durable for all weathers.

These sensors do what they are supposed to do and do it quite well. There are about 4 sound settings so if it's far from your living room, etc. you can have it on "high" in order to hear best. They're great at letting you know that someone (Amazon truck?) is coming down your driveway. Only caveat is that if the power goes out they reset at the highest volume and you need to press the volume button three times to get it back down to "low". Also, during some times of year blowing tree branches and leaves trick it into thinking that a vehicle is passing by. I'm thinking about relocating that one sensor. [The occasional deer can set it off too - but what are ya gonna do?]

Even on low setting, this device is sensitive enough to be triggered by birds or vegetation. When properly positioned, it reliably announces movement with user-selected tunes. It is designed to be water resistant but tucking it into a sheltered area might be wise. Batteries should be installed according to the markings on the battery compartment, not the user manual. The manufacturer responded quickly and politely to customer advice.

Does exactly what's advertised. Easy to set up. Only had a couple weeks not sure about battery life.

I purchased a different one before I got this one because I thought this one looked like it wouldn't hold up outside but it's great! So glad I decided to try it. It's sound emitter "ringer" that you plug in inside is smaller than I thought it would be but I love that too, it's so cute! It's barely noticeable and looks nice. It has a ton of chimes so that's fun if you're into that. I have had it for +/- a week or so now and maybe twice a bird has set it off but overall I'm so happy with the "no false alarms" and functionality of this thing. We use it in our driveway in the country. It worked right out of the box too and was easy to set up. You can add other "eyes" but it would be the same ring/sound so I thought that would just be confusing. It would be perfect for a porch or similar. I do have other areas I would like to have this so I plan on purchasing more so they will have different tones. I'm sorry I don't know the range. I have the "eye" on the driveway at the street of a normal size front yard and the "ringer" is in plugged in the entryway. Oh and you can plug in the "eye" and if that's an option for you. It comes with the batteries and the USB cable. (you will need a cube). It also has little sticky strips you can use to narrow the "eye" if you need that. Hope this helps. It's worth it. The first one I got cost more and just plain didn't work and was very difficult to set up. This is worth it.

Great when it works, doesn’t always work. This is the second one of this brand I’ve purchased when the first one stopped working. Cheap enough to get , but does not always alert when vehicles cross. Then sometimes it will ring for bunnies or birds . For the price it’s ok. But I wish I could depend on it.

This alarm monitor is one of the best I've purchased. It has a wide range of motion detection, is easy to install, and easy to set up. The detectors run on batteries and/or usb charge and have an on/off switch on the bottom alarm with the usb port. It's small and attractive, too. I like that the receiver actually plugs into my wall -- it doesn't run out of "juice" and start an annoying notice tone like some others. Also, I like that there are many alarm tones to choose from, some musical and some not. You can pair multiple units to the receiver and have different types of tones for each, which for me makes it easier to remember which tone goes to which location of detector.
