eMACROS 1/2 Mile Solar Wireless Driveway Alarm, 1 Receiver & 1 Sensor

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.

I purchased two different driveway alarms with the idea of doing some comparative testing. This is my initial impression of the Guardline GL2000 and eMacros HS-002 Solar Driveway alarm and I will add to this after the units are in service for several months. Sensor Appearance: both have a similar appearance and seem to be made from the same brown hard plastic; both are made in China; both "eyes" are opaque white plastic and flash red when they sense moving heat. The Guardline settings are controlled by dip switches inside the unit, whereas the eMacros has a panel on the bottom covered by a silicone flap with switches for sensitivity (including off) and channel selection along with a microUSB charge port for initial setup. Sensor power: The eMacros has a solar panel (obviously) and an internal 18650 lithium battery and the Guardline requires 4 AA batteries. The batteries on the Guardline can only be changed by removing 4 small screws through the front (they supply a screwdriver for this) and changing in the field might be difficult without losing one. Depending on how often the batteries need to be replaced, I may just take the unit off it's post and change them on a bench. The need to change batteries was my main motivation for buying the eMacros unit, since it should be more maintenance free. Detectors: Both have volume controls, offer different tones, can pair with different sensors if you have more than one and have a place for optional back-up AA battery power. The Guardline receiver is larger and square and sits on a flat surface at an angle. The eMacros receiver is disk shaped and sits flat on a table or can be hung from a wall. The Guardline is powered by a DC adapter with a round jack and the eMacros with a microUSB type charger. Documentation: Both come with quick-start guides and instruction manuals that are well written. The Guardline owners manual is much more extensive and detailed which describes features that Guardline has that eMacros does not. For example the ability to control external devices when the sensor detects movement and the ability to pause detection for a preset period of time, which would be useful when there is a lot of activity around the sensor, like mowing the lawn. Initial impressions: Both units were up and running in minutes once I had charged or put batteries into them. They came factory paired to their receivers and did not interfere with each other. I found the default Guardline tone more pleasant that that on the eMacro, but both are sufficiently loud to be heard throughout our 3 story house. Initial Performance: I placed both sensor units on a post 12 feet from the centerline of our driveway and 375 feet from the living room where the receivers are placed. Before long, a delivery truck came down the drive and both alarms went off. Note that this is well within the reported range of the Guardline (500 feet) and the eMacro (1/2 mile). The installation of both of these units was a breeze and both worked as stated right out of the box. Stay tuned for my long term update to this posting...

Works as advertised. Could not be easier to set up, nothing to think about. The receiver is inside the house, in heavy woods, with no direct line of sight, approximately 400+ feet distant from the sending unit AND the receiver is located 12' BELOW the sending unit on the down side of a bluff. No issues. We tested it approximately 800+ feet away (other conditions the same) for 2 days so we knew whether or not to purchase another sending unit... worked flawlessly at that distance also! Senses deer, people and cars at 10' away mounted 42" off the ground (set to high sensitivity). Does not seem to detect people walking at more than 10' from the sending unit. Leaves of trees, bushes and tall grass moving in the wind does not set off an alert. Charged the remote sending unit once (<5 minutes) when we initially set it up and have not had to charge it since despite 2 rainy days and it being partly shaded from direct sun most of the day. In use night and day for 2 weeks now - I'll update this review if something significant changes. Additional thoughts; 1) Would prefer the receiver unit to be smaller, more portable shaped and weather proof so we could more easily carry it with us when we're walking or working on the back part of the 40 acre property. 2) Would prefer the receiver did not have such a large, bright and constantly on indicator light (under the "3" button-just indicates the unit is on). A tiny red LED near the on/off switch would work just fine. 3) Really needs an indicator LED to let a person know at a glance the sending unit is being received by the receiving unit. There is no way to know without 2 people, 1 of them having to walk out to the mounting location. Would prefer the reassurance at a glance, day or night, that the two devices were still connected. 4) Would prefer more attention-grabbing alert-like tones rather than the musical tones the receiver plays to announce. 5) A phone app would be great. 6) Would prefer the driveway alert not include the small screwdriver in the package. Most everyone that will install this themselves already has a screwdriver and if you're paying someone to install it for you the installer should bring their own tools. Deleting the screwdriver would save the earth from one more throw away and lower manufacturing cost that could be passed on to the consumer. Conclusion; This wireless driveway alert does what it says and does it well. My wife and I are very pleased by its functioning, would buy it again and recommend it. We have tried another driveway alert in the past and returned it after a few days - it failed to function at even 40' and was very troublesome to set up. 7/16/2021 Felt compelled to add this footnote. My original review is accurate. I have had the devices for several years now, they still work flawlessly! I will soon be purchasing another sending/sensing unit for a total of 3. Here's the addendum; This company shamelessly courted my positive review and promised me $25.00 for it. I provided an honest, and I feel, positive review. No compensation necessary. ... And the company never paid me as personally promised by the people who answer the phone when you call the company. Just so everyone on Amazon knows who they are dealing with on this product.

This works perfectly. Im several hundred feet away from sensor. Love this thing

I did not know how this was going to work out after reading how it was supposed to work. However it has been a couple of years since I have owned the driveway alarm, and it is still working after going through a few seasons of harsh rains and snows and freezing temps. Now you have to keep in mind that the sensor is going to pick up flying insects, birds, squirrels climbing the tree that I have it mounted on, and the occasional falling leaf or blowing debree in the wind. The sensor is sensitive picks up almost anything that goes i front of it. I always know when wildlife is around and it always picks up any vehicle that comes up my road. Of course this is what you are wanting it to do, and it does it very well. You just have to be willing to deal with all the other items it can detect. For instance , I have had a lot of flying insect or blowing debree false alarms, but better that it alerts you than not be working correctly. You can't program it to only pick up automobiles and ignore animals, its going to detect it all, even unwanted humans invading your property. The reciever does have a the ability to adjust the volume of the alarm and you can add a couple of more sensor/transmitters to it with different sounds so you will know which sensor is going off around your property. It would come in handy to place one in the back yard to detect intruders. I am just now doing this review and mine is still working very well. At least it is doing well so far. I'm going to be honest and say that I anticipated it to stop working because of harsh weather after a while, but this little alarm system has been doing great. I am thinking of adding another sensor to it.

We live in the country and have a very long driveway. We have wanted a driveway alarm for years to alert us if someone is coming, or if packages have been delivered, etc. I had purchased one a number of years ago for my parents, and although it works great, it cost more that $200 and required digging a trench near their driveway for the underground cable which detects the vibration of a vehicle. It also didn't have the long range we needed and the receiver had to be in line of sight with the sensor unit in the driveway for it to work. When I saw this eMacros alarm was solar powered, had a half mile range, cost only $50 and was simple to set up, it seemed too good to be true. I went ahead and risked it based on the reviews, and I am so glad I did! This driveway alarm works GREAT! I zip-tied the sensor to a south facing tree about 2/3 of the way down our roughly quarter mile long driveway. The driveway is curved and sloping, so you can't see the sensor from the house, but that doesn't matter as the reciever activates and the alarm sounds inside the house just fine. The alarm sounds for any vehicle traffic, but also people on foot, like my son walking home after the bus lets him off after school. We've only gotten a couple false alarms which have come after dark and we assume are deer. It is nice to have something so inexpensive and so simple to set up work so well. I love having this alarm! The only thing I wish is that I could purchase another receiver to put on the lower level of the house so I can hear it if I'm downstairs sewing.

We are loving our new motion sensors from Emacros! This was so easy to set up. It didn't take 5 minutes to figure it out. And it was pretty easy to go out with the screws that they gave us to set it up, to just screw it into some of the wooden posts along the fence line. The whole sensor is on a swivel. So you can move it to the side so you can get to all four screw holes. But it also helps on moving the swivel to aim the motion sensor in the direction you want in at the height that you want. We live on a home with some acreage and we have a long gravel driveway that is more than a quarter mile long. When it goes off, we know an individual is driving up our driveway. The only problem is, when that motion sensor goes off, we are looking to see who this individual is driving up our driveway and being a gravel driveway it takes a while for them to come down and get to my house. And sometimes, we never see a vehicle because it was possibly a deer or something else like that walking in front of it. Only one out of 10 times is it not a vehicle. But we already knew that by having deers, it would set this motion sensor off from time to time. But, to solve both of these problems, we purchased a second motion sensor. And we set it up further down the driveway. This way we know if it's a vehicle, it would set off both motion sensors. Because I don't think a deer is going to walk down my driveway and set off all my sensors. Lol. For people with long driveways, I recommend purchasing at least two sensors. This does an incredible job! Update.... I have 2 in my driveway. 3 years later, neither is working.

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).

This driveway alarm was perfect for us with the front gate over 100m away from the house and works perfectly and so easy to install ... great product

Very pleased with our purchase, we bought a two pack. This sensor gives us peace of mind that we know when someone pulls into our drive way. Great sensitivity and range. Very easy to set up and being able to change the alert makes it easy to know which sensor is being activated. I cannot comment on the battery life as these were recently purchased. We also purchased more of these sensors for family and friends.

Easy installation. Good service. After sales support. Works like they say it does. Really pleased with my choice.

We got this for the driveway. It is easily enough hidden by the garden fence. It required a week or two of adjustments. A few butterfly's kept flying in front of it. The Robin's also enjoy it. Now it picks up vehicles. There is a receiver plugged inside the house with 4 options for chimes. Does not work in power outage.

I was doubtful if it would be able to transmit thru a steel building, but it does with no problem. I have it mounted to detect cars coming up the lane towards my building and the receiver plugged into an outlet in side. It has to transmit thru a steel sided building and into an office and does that with no problem. It has given a few false alerts or possibly birds that have triggered it. It has 2 settings, a 20 ft and 30 ft, that I assume might be sensitivity settings so I will try to set it at a lower setting to see what happens. I only can confirm it works fine for cars, but since I do not have people coming down that lane I can't confirm how it would work for persons.
