Customers say
Customers find the driveway alarm system easy to set up and appreciate its solar power feature, with one customer noting it works at very long range. They like its alerting capabilities, with one mentioning it alerts them when visitors arrive, and consider the use guide excellent. However, the functionality receives mixed feedback, with some reporting it stops working after two months. Additionally, the system is not waterproof, and one customer mentions it makes continuous noise throughout the day.

Works well
Great product. The receiver is probably 100m from the sensor and still works really well to alert us to cars or people on the driveway. Fully adjustable angle/height/sensitivity means we can avoid catching the dog every time she runs past too

Easy set up, and it works. Not tried it at 800 mtrs but it works fine at 300.good bit of kit

Embarrassed
This alarm stopped working within 8 months and there as usual I’m finding it difficult if not impossible to contact seller.And as is always the case amozon wash their hands of any responsibility!!! Ps the seller could not have been more helpful and replaced the faulty item swiftly. I now feel ashamed of my review .I was more frustrated with Amazon.

Rusted through U2 procesor leg
I have installed these sensors, 1 has failed due to water ingress. They are sold as waterproof , which they are obviously not.

A brilliant device
Well made and works well. I use it to warn me when wild goats come into the garden and every time I get the warning. The solar is great as I don’t need batteries. I will definitely buy another one.

Does exactly as advertised.
We use this item to create overlapping fields of monitoring around our rural house. It works at very long range, alerting us to visitors on multiple approaches to the house. It does not seem to respond to deer, and thus distinguishes for arriving vehicles or visitors on foot. Be advised the alert monitor is quite loud, so emplace in your house appropriately!

Randomly goes off
Worked fine for a week or so, then randomly started going off when clearly nothing there, checked for spiders etc none there.Its outside our gate to let know when someone pulls up, but doesnât always pick up cars that are right in front of it, then itâs going off in the night for no reason had to turn it off in the endItâs good because itâs solar and donât have to change batteries but the cheaper one I had last time worked better until water got in battery compartment.

Sensor stopped working after 5 months
Stopped working after 5 months it was great up to a point when it stopped working when motion was detectedBut it would alarm just out of the blue when no motion detectedTried to find details on Amazon to explain canât find any information to ask for repair or replacement

So easy to set up and install. Does exactly as described. Superfast shipping, good quality and right price. I first set up the sensor with double sided tape to be sure to get in the right spot before securely fixing which worked well. The unit occasionally goes off when birds fly in front of the sensor but as I can see my front gate from the house this is not a problem.

3rd set I have purchased.Work good for 6 months then start to fail.Tried recharging with minimal success.Work great when they work but I have basically thrown away $200 .Maybe they will reach out and send me an upgraded set that last longer than 6 months.

Recently after almost 2 years my sensor which I installed to alert someone entering my driveway wasn’t alerting as it always had. I did some trouble shooting & researched Q & A on the product. I felt the solar battery had finally gone bad & one answer did indicate the battery could be replaced. I opened the sensor but the battery was so encased in the unit I was unable to go further. I then found the companies contact info. which was only via email. I reached out to them with my issue & received a very prompt & caring response. After following their suggestion on a possible solution the unit still wasn’t alerting. My communications were with Robin & she had offered that if my problem continued I should request a replacement sensor which would be promply sent to me. Ultimately I did make that request & as promised & without hesitation or delay I was sent a replacement Motion Sensor replacement which I received within days. I was able to activate the new sensor with my existing receiver & it now works perfectly & I have that peace of mind again. I write this because I am pleased with this product but the main take away here is the excellant, prompt, curtious customer service I received from Robin. Customer service is a big priority with me & not all companies understand its significance. Even though the communication is via email it went very quickly & successfully & for that I thank Robin & HTZSafe.

I have three of these down my long wooded lane. No one sneaks up on me now. The only problem is sometimes squirrels like to chew on them, but I found that a plastic snake stops that cold.UPDATE: They lasted one year before they started getting trigger happy. As in they would go off at seemingly nothing. With three of these though I could still tell if someone was coming or not because they would trip in sequence. One year in these harsh Texas conditions is really good in my opinion. We have hail storms, blistering summers, torrential rains, zero degree days. So I replaced them this past week. If they last another year I’ll be super happy.And the customer support is excellent. Originally I had an issue and I contacted them and they had a replacement in the mail that day. No hassles no arguments.
