Supplemental Solar Driveway Motion Detector&Sensor (Sensor only,can Work independently Without Receiver)

So far so good. I now know when someone is at my gate, I live in a very rural area so now I don't get surprises. I put one on my carport to protect my vehicle, equipment and the entry to my shop. I don't know if the 1/2 mile range is accurate because my driveway isn't that long, but it does work good at about 400-450 feet. You can control how loud you want the notification and on the detector you can control how far you want it to detect up to 30'. The installation was simple and was done in a couple of minutes. These are well worth the money. The company has made a good product that is easy to use and very helpful.

If it was possible I could have given it 10 stars. There are not may products built like this. absolutely fabulous! I am using this for perimeter security. I ordered 4 sensor system that comes one base unit. I have hooked it up with my secondary alarm system for triggering a siren and warning lights. I have mounted two alarms on two opposite corners of my property, each pair inside a wooden housing at right angles to each other. The wooden housing prevents false triggering from objects that are outside the periphery. I control the secondary alarm through google assistant, relays and wifi switches. I tried several other alarm systems but none came close to this one. The product has super amazing battery. Once charged it lasts for more than a month. The sensors keep themselves charged with the sunlight. The detection range is awesome. I initially thought I would need additional sensors to allow detection for each edge of the property, but one sensor for each direction was sufficient for the job. The base unit is quite small, you can carry it anywhere if your property is large and you will be at different places at different times and you want to have a tab on who is entering your property. When I started with the project, I found that base unit came with an earphone jack. When a particular sensor was triggered, it would send a specific tone through the speaker of the base unit or through the earphone jack. I wired up photo resister light sensors to detect the flashing lights and then trigger a relay to sound a larger alarm with flashing lights to deter the intruder. I inquired BetterLink (vendor) if there was a way they I could trap on the light signals from the wires instead of relying on secondary detection through photo resister sensors. Their awesome engineering team immediately got to work. They enhanced the product to send the detection signals instead of tones through the earphone jack of the base unit and shipped me two base units for free. The earphone jack (stereo) could be used for emitting output only from two different sensors, so they sent me two (thanks BetterLink, you guys are awesome). I have connected the two base units to my main system and my entire system is working beautifully. Absolutely recommend this system. There are numerous possibilities if you want to use the product for other projects.

Great customer service. Quick to replace one that stopped working. The loud alarm on the sensor is what sets it apart from others. Great deterrent to those attempting to break into cars.

This works GREAT! I have had zero issues with it. Make sure you cut any vegetation from around and in front of it that may possibly move with a breeze, as it will set it off. Otherwise, amazing product!

it has been working reliably even on several consecutive cloudy days, except that the the receiver should be louder, and should have a resettable display of the nunber of triggers. UPDATE 5-14-25: changed from 3 to 4 stars. For the price, this is a good item.

The solar owl alerts are working great.

I purchased multiple of these kits: one for a friend and one for myself. I helped my friend with setup and all is working great at his house for driveway sensors. I am personally using the 4 sensor kit to alert me of predators (coyote, bobcat, etc) at my back fence in addition to driveway sensor duty. I really appreciate the range and reliability. I am using these to monitor dead spots where my security cameras and wifi signal won't reach. Instructions are provided to configure them for first use. You have to be careful during setup or the channel assignment can change inadvertently if one of the other sensors gets triggered unexpectedly. Better to configure them all at once at the workbench before installing the sensors around your property. For comparison, I also purchased an alternative, simpler product that plugs into the wall outlet and doesn't require any additional configuration. HOWEVER, this product is FAR SUPERIOR to a plug-in product because of the rechargeable batteries of the base station. This means it continues working during power outages and is easily portable to any location around your property. For my particular needs, it was also necessary to have different channels so that I can hear different sounds depending on the location. I cannot imagine how annoying it would be to deploy 4 sensors at opposite corners of your property hearing the same exact sound, not knowing where to look. Fortunately, with this product, I can use 4 distinct sounds to focus my attention where it counts. I have not used their customer support because everything worked perfectly out of the box for both of my purchases. I don't know how well it works in the rain but I will find out soon.

These work great. I haven’t tried max distance but my chicken coop is about 45 yards away and we haven’t had an issue since. Detects small and large critters. Able to catch coyotes in the act and able to get excited even when a squirrel walks by. Highly recommend. We even got paint spray all over the solar panels and they still work no problem with shade most of the day.
