1/2 Mile Long Range Solar Wireless Driveway Alarm System IP65 Weatherproof Outdoor Motion Detectors&Sensor 120dB Siren Sound Light Security Alert System Monitor&Protect Outdoor/Indoor Property(1R1S)

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.

I was very pleased with the easy setup and performance of this driveway alarm. I doubted the signal would reach 600 feet downhill through tree cover, but it works great. After 4 plus months of use, the solar panels are keeping the sensors charged even in partial shade and the base station needs charging about once a month. This system was a good value and I will likely expand it with additional sensors soon.

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.

Showed up in good condition and on time. Gives a notable tone when an object trips the covered zone. Works good for cars and people and will also trip on animals and larger birds so be careful how you setup and you can minimize false alarms.

The alarm system came pre-configured. There was nothing to set up or connect. Just turn on the receiver and sensors and it works great. I love that it is solar and USB so there are no batteries to ever go dead or replace. I have the sensors positioned on an off-grid property and they work fantastic. I haven't tested their full range to see if it's 1/2 mile as advertised, but I can say from experience they work well at around 1/8 mile with clear line of sight. There have been no false alarms even with the sensitivity turned all the way up. If you don't want small animals to trigger the alarm, mount the sensors higher and tilt them more up off the ground. The alarm sound and lights annoy the heck out of the coyotes who have since sought other, more tranquil accommodations elsewhere. You can also configure the sensors to lights only, alarm sound only or silent alarm with base station ring only.

Works great use it on my long driveway. Works perfectly every time! Solar keeps it charged with ease. Distance not a problem with this unit. Definitely the best driveway alarm on the market.

Après 3 mois d'utilisation, c'est parfait. Installé en quelques minutes, pas de pile à acheter, ne se déclenche pas pour rien, ou c'est qu'un oiseau passe devant (un pigeon chez moi !) Le choix de sonnerie, et de volume et simple, et une très bonne distance entre les boîtiers émetteurs récepteurs, tout est bien fait. Reste à voir dans le temps, si tous tombe en ruine dans un an, mais soyeux optimiste.

I live in a heavily wooded area. I put the transmitter at the entrance of my driveway about 400 feet from my receiver. There is no problem with it transmitting through the thick forest at that distance. I like the fact that it’s expandable with other transmitters and able to pick different tones for the different transmitters. The only annoying thing for me is the green light that flashes constantly on the receiver. I had to put tape on it to dim it down for night time. I highly recommend this unit
