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

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.

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

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.

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.

Very satisfied with the available tones,there is many.Works wonderfully.

Works great We Use it so that we know when our pet are waiting at the door.
