eMACROS 1/2 Mile Long Range Solar Wireless Driveway Alarm Outdoor Weather Resistant Motion Sensor & Detector-Security Alert System-Monitor & Protect Outside Property

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.

We love this! Super easy to install! We have ours on our gate post about 4 ft high and pointed it down toward the driveway. Works great. Now we know when our Amazon packages arrive!

I used this on my driveway as it is quite long and I can not see the gate from the house. Everything works exactly how it should, I can not recommend enough. It was easy to set up and easy to maintain.

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.

Works exactly as advertised. Bought it to let us know when someone steps up onto the deck. Did not want a video doorbell as it would capture every single neighbour's comings & goings. No more missed deliveries now because the doorbell can't be heard over the TV or other competing machine noises. It comes with 4 pre-drilled holes on the rotatable sensor plate. Attached it with zip ties to the deck railing. Live in a condo and did not want to have to apply for approval and sign a waiver form to drill holes. Four new Energizer batteries were inserted into the base. They are already running low after less than 2 weeks of use and always being on. Have switched to AC power instead losing the portability to put the base wherever needed. The solar charging functionality on the sensor is nice. It was the main reason we chose it over another highly rated and lower priced outdoor sensor available on Amazon. Did not want to have to replace batteries regularly. Winter has yet to arrive. The sensor is rated to function in extreme temperatures. Hope it continues to work as advertised through the wind chills & deep freezes of the winter months as this sensor was not cheap. The sensor appears to be sturdy and well made though. Will update this review if it does not work as intended over the winter months. If no update posted, it is still working.
