1/2 Mile Hosmart Driveway Alarm Wireless Sensor System & Driveway Sensor Alert System Weatherproof Security Outdoor Motion Sensor & Detector

Honest review: I have the previous version with the rechargeable battery bought in May 2021. That being said, I think all of the features and quality will be the same. This alarm system absolutely works as described. My house is in the woods, so I wanted to know when someone approaches. My driveway is 800 ft long, however the sensor is located on the front of my detached garage nearer to my home about 150ft - 200ft from the alarm. In the almost 4 years of owning it, I have charged the sensor maybe 4 times. I estimate that the alarm is triggered around 10 - 12 times a day. I keep the alarm in my home plugged in so I cannot speak on battery life with that.The alarm in the house has options that I have never explored as I only use it as it came programmed i.e. various tones and zones, I think for multiple sensors.Pros:1. The sensor has withstood our New Hampshire weather, freezing cold, snow, and freezing rain without breaking.2. Battery life is very good with charge lasting well over 6 months (cannot speak to replaceable batteries).3. The adjustable alarm is loud enough to hear throughout the house.4. Never an issue with quality.Cons:I do not have any cons to list but here are some things I've dealt with primarily due to my placement of the sensor.1. Wildlife will trigger it as should be expected, birds, rabbits, squirrels, and once a pair of coyotes passing through in the middle of the night.2. Falling leaves in the fall triggers it.Tips:1. Don't place the sensor where you do a lot of activity like I did. I don't typically work out of my garage but on the occasion that I do, the alarm will continue to chime every time I enter or exit the door (drives my wife and dogs nuts). She simple unplugs the alarm until I am done.2. The alarm will chime if you place the sensor where delivery trucks i.e. UPS and Fedex need to turn around. My driveway requires them to do multiple point turns and it happens to be right in front of the sensor.I will probably be moving the sensor down the driveway a bit to avoid these unnecessary chimes.All in all, this alarm does everything it says it will do. It alerts you when triggered and quality has never been an issue. When the time comes and I need to replace it, I will not hesitate to stick with this system.

Well worth the money

easy to install driveway detector. Very long range, easy to set up. Very sensitive to movement will detect squirrels on most sensitive setting. The ball joint adjustment mechanism is plastic for weather resistance, but very difficult to tighten with fingers, I needed a set of channel locks to tighten this wimpy plastic nut so the sensor head was tight. Would be nice if there were other optional announcement voices instead of "driveway" driveway" Would glady give 5 stars for a nicer plastic ball joint nut and optional detector announcements.

Have been using now for four months. Purchased two transmitter units and one receiver. Screwed one transmitter to the back of a plastic mailbox (did not work in metal mailbox) approximately 1100 ft from the in house receiver and the second transmitter at entrance to driveway at about 1000 ft from receiver. Set receiver for two different channels. The signal has to travel through mostly heavily wooded area and gradually down 100 ft slope to the receiver. We were impressed as to how well these worked. The mailbox transmitter has had No false alarms as to date (black mailbox) and the driveway transmitter has had only about 10 false alarms. The false alarm on the driveway transmitter was due mostly to the late afternoon sun hitting the transmitter. Changed the angle of transmitter a little (away from sun) and this reduced the false driveway alarms. Have Not had to charge the batteries so far after four months of use. There are four sensitivity settings and four different channels (for four transmitters) on the the receiver if needed. The driveway transmitter has only been tested on the heat from vehicles and works well. The mailbox transmitter has been triggered by heat from our rural mail carrier and has worked flawlessly. Have had no problems with system since initial setup. No problem during rain. Set up was easy but had to make minor adjustments the first few days, angle up-down and side to side using the swivel mount. Sensitivity is set on two for both transmitters. Would highly recommend.

Work well for awhile then batteries stared not lasting but a couple of weeks then started giving false alarms bought in March 2025 stopped working in June

I own a campground and live on the premises. We figured out early that we needed a way to monitor when someone comes on the property. I first purchased these sensors in Jan 2019. I put one receiver in the house and one in the office, with one sensor on the front gate and the second on the back driveway. They have worked really well for the last 5 years. I take the sensors down and charge them once a year. Last month one sensor stopped working. Figured out the battery was no longer holding a charge. I ordered another sensor to replace the failed one and another receiver so I could monitor from a 3rd location. Long story short, the newer units would not work with the older units. Contacted Hosmart customer service and they responded the next day. They informed me that the new systems would not work with the old one, but, offered a really nice discount to upgrade my whole system. I feel like my rep, "Bella" went above and beyond to make things right for me. I highly recommend this system if you need to know when someone's coming on your property.

It took a lot of work to get the sensor aim just right because I live on a busy corner. But now it works wonderfully. I love that I know when someone is here and I don't have to stand at the door and look out. It does catch birds that fly right in front of it. But it doesn't happen that much. It will be interesting in winter when snow falls. I'm imagining it will change the aim and I will have to play it all over again. I really like it. I am very pleased with it. My friends are very impressed with it. I never hear the lie from people how they sat in my driveway waiting for me for 10 minutes. They can't do that. I know when they pull up now. I am so happy.
