eMACROS Non-APP Wireless Driveway Alarm — 1/2 Mile Solar Motion Sensor with Plug-in Receiver for Driveways, Homes, Large Properties, Weatherproof Outdoor Security System

I had another brand that lasted about 3 years or so out in the weather. I like the "disc" design. The other unit had a single unit that plugged into the wall taking up the entire outlet. It was easy to set up and install. I use it at the end of my 100 yard driveway and it is very reliable. The only issue I have found with these types of sensors is if there is no sun for several days they might not work. We don't get a lot of traffic so I rarely have this problem. The sensor can be plugged in using a USB-C connector if power is available.

Works very well and lets me know if someone is entering my property. But it will pick up birds, cows, and brush. So check where you put it.

This may not be the least expensive driveway alert system, but it does work well (so far). I installed it about a month ago. In the woods, where my driveway winds through. The leaves are gone, now that it is winter, so there is sunlight. I charged it up via the USB charger before installing it. That is something that is not clear in the description: You can (and probably should) fully charge it before installing outside. It can be charged like any other electrical device that charges via a USB port. Supposedly, even if there is no sunlight available to charge the battery, it will stay operational for many months if you first charge it via USB. The car detection works fine. A few other things get detected -- such as deer (I assume, since I really can't see what is being detected). But the non-car detections have been few. Set-up is easy. You have about 30 alert sounds to choose from, and you have to pick one. You can scroll through them to hear each one before picking. You can change it to use another sound at any time later. The sounds that are provided are a bit limited, and some people will be dissatisfied with the options. I do not like the "ding-dong" doorbell sound -- because it is too confusing to have to distinguish it from my normal doorbell. So, this option is sort of ridiculous in my opinion, when most doorbells have the "ding-dong" sound. There is no simple "buzzer" sound -- which my previous alert had used. I have no need for the "back door", "side yard", etc. pronouncements (which are only useful if you set up multiple detectors.) I just wanted a sound that I could definitely identify as "car driving up my driveway". There are only a few options available, once the stupid ones are eliminated. I picked the "Adams Family" theme song -- which just plays a few bars. It's fine for my purposes. So, this alert system works well, and I can't yet say how well the solar charging works. My down-grading to 4 stars is only because of the limited number of good sound-alert options available. The ability to send signal through the forest is perfectly good at 700 ft (or, it may be more ft).

We live on 20 acres and have a long, curving driveway. For privacy’s sake, you can’t see our house from the road, which means we also can’t see when someone is here until they’re at the top of our driveway. We can’t always hear if someone drives onto our property and got tired of getting up to check every time one of our dogs barked at a passing bird. I had high hopes but was concerned these wouldn’t work well since we live in the jungle and it rains like 300 days a year. Heavy rains sometimes and I thought for sure the rain, wind, leaves blowing around in the trees would all set these alarms off. Nope, they work like a charm! It took us a couple weeks to get the adjustment for the sensor just right, my husband says they need to be angled just slightly upward to prevent going off for the random animal that passes by...we have wild pigs, mongoose, rats, cats, etc. that would set it off sometimes. Once we got the sensors to stop “seeing” the ground, they only go off when someone walks or drives passed them. Occasionally a bird will fly passed the sensor and set them off, but otherwise we don’t get false alarms from leaves blowing in the wind and they work even in heavy rain. Our neighbor’s black car can get passed the sensor that is farther away when it’s super dark out, but the other sensor always picks up his car. We set up two sensors, one closer to the road and one closer to our house, and we set them to have different “ring tones”. This way we know if the alarms go off in the right order, someone is coming up our driveway. We did this so a random passing animal setting off one sensor wouldn’t have us jumping up to see who was here all the time. Turns out it wasn’t necessary as the animals don’t set them off very often. But it is nice to know if only one alarms sounds, it’s probably nothing. We used the included cord for the alarm speaker to charge the sensors fully before installing them outside. Even on cloudy days they’ve collected enough charge to work through the night. At least we think so since animals kept setting them off at night until we adjusted the sensors correctly. They are super easy to install. The speakers also use batteries so they work if the power goes out. I love this feature as I can carry a speaker out to the greenhouse or elsewhere on the property and still know if someone has come by to visit. It’s also good to know that if someone tries to sneak onto our property in the middle of the night, we would be alerted.

5 Stars; no big problems since 2019 when I bought 2. I observed any problems with water penetration of units. The plastic did crack eventually at one screw hole. I think that the plastic is slowly deteriorating by UV from the sun; so I suppose ideally one would paint the plastic w/ UV stopper paint. But this is an unusually good consumer product, as it is faithful, the sensor is powered by solar, & the receiver can be powered either with 4 AA batteries or a supplied power supply (5 volt USB type). The same supplied power supply which gives intitial charge to the sensor unit, also will power the alarm units. After initially charging the sensor unit, the built in solar panel provides the rest of the powering for the sensor unit. When I bought this the separate receivers cost about $50, I decided to go ahead & by a 2nd transmitter/receiver combo; they don't list a sensor-transmitter with 2 receivers as a package unfortunately. I bought 2 morerecently & found that the sensor + alarm package was not that much more than buying a separate sensor. At first, I wanted one receiver for inside & one outside to scare off intruders. It would have been more convenient for me if they had included self-tapping sheet metal screws for installation, as what they provided proved not of high enough quality to penetrate easily a pre-drilled hole in a steel fence hollow rod. The first night I installed the sensor at about 2 feet off the ground , it went off apparently for sensing a cat. Then I changed location of the sensor-transmitter, putting it about 5 feet off the ground, and thus far (2 days) have had no known cat activations. The ability to set the transmitter for 4 different chimes lets you use multiple transmitters in different locations with only 1 receiver; the receiver playing the selected chime for the transmitter activated. I set one chime for Lone Ranger Theme (Wm Tell Overture, & the other for 1812 Overture, as they seemed louded & most attention getting). I set a sensor receiver about 4 feet insider my yard gate on the side fence to which the gate is attached, which is about 40 feet from my front door. I put it back a bit since I did not want passing cars to set off the alarm. Then I put the receiver inside my house, on the cross bar of a window, which window has a metal screen (which I did not remove). The alarm faithfully went off inside the house & I can hear it even in a back room of my house. It even reaches attic (like 2nd floor) towards the back of my house (about 36 feet from front of house, maybe 70-80 feet from the driveway sensor, which is down hill to street. So the range of the RF from sensor to alarm is really good for my purpose. I can now hear the alarms when I am in my study on 2nd floor at rear of my home. At the entrance of my driveway, 1812 overture is set off. As person walks up my driveway, Lone Ranger goes off. When they reach the gate of my inner perimeter fence, I get both alarms. So I get an idea as to where the visitor is. Now nobody needs to ring any door bell. Now it is hard for a delivery person to falsely say he came on Sunday with an Amazon delivery & nobody was home (when we were home). These great units remove the need for a door bell. Maybe I will set up an ooga horn to go off at night if somebody enters my castle grounds, but I don't think they make an ooga variety.

These things work great! I just got them about two hours ago and they are already up and running. We have a walking path and a large park right behind our backyard. There has been an uptick in graffiti on neighbors fences and along the path. There are some homeless people that have moved into the park and we thought it might be a good idea to increase our security. We bought some solar motion lights and mounted them on the outside of our fence. They worked great for a few weeks until someone ripped them off our fence. We decided a more discrete approach might be better. We ordered Two sensors and an extra speaker so we have one downstairs and one in our bedroom. After delivery, it took about 30 minutes to unpack them, familiarize myself with how they work, top off the charge of the sensor and attach them to the fence. They work great! So far they’ve worked almost perfectly and have been triggered every time someone has walked/biked by. Each sensor triggers a different chime so you can easily tell Which zone has activity. So far few false alarms. The only drawback for me is that the sensor itself lights up when it is triggered, which brings attention to itself and clues in someone that may be doing wrong, that they are being watched. I prefer for them to be oblivious. You can avoid this feature with two sensors but if you use more than two sensors, the third and fourth sensor lights can’t Be turned off. Another concern is that they automatically pair to each other and all the equipment is on the same frequency, even though I bought them separately. This makes setup a breeze but I’m worried that if anyone within a half mile has this same product, it will set off my system too. Update: A day after I bought these, one sensor triggered in the middle of the night. I looked out my window and sure enough, two meth addicts were walking by. They saw the sensors and panicked. I think they thought they were cameras and scattered like mice. Edit: it’s been a couple of months now and two out of three sensors we bought are now less sensitive and have less range than they originally did. Now people can walk by on the path without setting them off. We also bought a fourth sensor for our front door but it gives continuous false alarms to the point that it is worthless. Because if this, we remounted it ( drilled more holes in our house *cringe) to face a very small area with no movement what so ever. It still gives false alarms all day long. We aren’t happy with this product anymore.

I have used several different brands and types of driveway alert systems. Most of them failed in some way. Either the range of operation, weatherproofing, missed alerts,etc. I was a little skeptical about the claims for this product. It says half a mile, but I only needed it to work about 400 ft. So far, it has been flawless. I waited several months before writing a review because I wanted to have it perform in various weather conditions. So far, so good. No issue with the solar charging. Have yet to get a low battery alert even though we did have several days of cloudy weather and rain. The only downside using this, and I say it is not a fault of the product, I get alerts at odd times. 3am or 4 am, Midnight, and so on. I thought they were false alearts, but turns out because I had the sensor installed too low to the ground, it was picking up small animals and sometime birds. Also, in the night hours, it was picking up a family deer that frequent my yard. Again, can't complain about the product. It works well, especially for the main reason I bought it. Mail deliveries and Amazon delivery alerts. You can use up to four sensors with each reciever . I leave my reciever pluged into a USB power source, so I don't depend on the batteries, but the instructions say the batteries will last about 2 weeks if you only use battery power. The batteries are intended for backup use in case of power failures.

You have to be careful with the install location because it will false a lot. It would not pick up people and even sometimes cars at night on low sensitivity. In daytime on Low worked well. Had to leave it on high sensitivity to catch night time movement bigger than a cat. But it would false sometimes.
