1/2 Mile Supplemental Hosmart Driveway Alarm Sensor (1 Coffee Sensor only)

Excellent Motion Alarm System!★★★★★I’ve bought the HOSMART 1/2 Mile Long Range Wireless Driveway Motion Alarm System twice now, and it’s been really reliable. The system comes with a base receiver and three tan sensors, all of which are weatherproof and work perfectly outdoors. The long-range capability is impressive, and I love how it alerts me whenever there’s motion detected on my driveway. It’s easy to set up, and the sensors have a good range and accuracy. Definitely a great investment for anyone needing a reliable motion detection system. Highly recommend!

I wasn't impressed with the colour as I wanted my alarm to be completely invisible. So I repainted the sensors. Easily done. My alarm is set to notify us when someone is at our front gate 100 yards from the house and also the location where the visiters/intruders are on our property.What we found is that this device can protect with 4 sensors or it can protect 4 areas with multiple sensors which is how we use it.After one month of using this alarm it works perfectly in all weathers. We get very little in the way of false alarms and that can be a bird sitting on the sensor or a wild animal in front of it. But that is only because of where we have placed the sensor. The range we did a test and it was somewhere near that distance in line of sight. But what impressed us a lot more is that our first sensor at the gate has it's signal going through trees and bushes in full leaf. Then through a large timber insulated building with 10" thick walls. Then through a twin 12" thick concrete walled house with multiple 4" thick internal concrete walls to the back bedroom. A total distance of 100 yards plus.So far, very impressed. The colour I altered with a bit of green/brown paint.What you get with this product is not just a driveway alarm, but a great security alarm which can be used to track your intruders. It is ok being notified of a triggered alarm, but by careful placing of the sensors this system can alert you to threats and track their whereabouts on your property. If you use this system with live video or game/trail cameras. Intruders can be tracked and filmed and you alerted while seated in your house.The ability for the sensor signal to penetrate multiple dense solid objects/walls makes this system far superior to other similar products on the market that I have tried.UPDATE NEARLY 4 YEARS LATER:Still going strong. Sometimes in rainy weather people slip by, but 99% of the time all good and no faults. Having multiple sensors detects those who slip by. Battery life is at least 3 months between charges.A great product for once.A real improvement would be to upgrade the system. Have 8 or 10 sensors and different alarm tunes for each.UPDATE NEARLY 5 YEARS LATER:Still working great with the sensors detecting daily multiple times and charging needs doing about every 4 months. One of the best products I have ever purchased from Amazon.

I live up a farm track so have set this up at the gateway to let me know when someone arrives. The motion detector is about 25' from the receiver (which I've plugged in but could be run on batteries and is positioned on a windowsill facing the detector) and so far everything seems to be working well and I've had far fewer false alarms than a cheaper model I've previously tried.It was a bit if a faff to set up as the design is really silly. The distance/sensitivity setting switches are inside the main body of the detector and if you decide you want to alter then once you have mounted it on a wall, you have to unscrew 4 screws on the mounting plate plus 4 fiddly screws on the detector housing to get at them. In a tricky set up like mine on an angle, with a slope, with pets and farm animals to avoid and test with, it took multiple tries to get the settings and position right and unscrewing it each time was frustrating and it worried me that eventually the plastic screw holes would break. Another really stupid design feature is the fact that to charge the detector I'll have to take it down again to plug it in inside somewhere or drag out the extension cord to it. Again, a better design would have an easily removable rechargeable battery so the detector could be left in position. Can't comment on the battery life for now but hope it lasts a good long time for this reason.Saying all that, I did eventually get it up and now the frustration of installation is somewhat forgotten, it is working well so on balance it was worth the extra money. The cheaper model (that was about £15) constantly went off when branches moved in the wind, the sun heated up things in front of it or animals passed it but this one has better sensitivity and distance options so has only had one false alarm so far and accurately warns me when a vehicle or person arrives. The brown housing is unobtrusive and blends well on a fence post and the alarm although a bit tinny is loud enough to hear in the next room but is not too annoying.
