driveway alarm provides a convenient and economic way to alert you the moment when someone is approaching your home

I bought these after I walked up on three large men attempting to rob one of the trailers filled with products that I've been hired to watch on the grave yard shift. As a female security guard working the graves in a very dark truck yard. I frequently make my rounds and after that incident I bought 10 sensors to put around the trailers so that I will be warned ⚠️ ahead of time that someone is walking around the trailers or attempting to rob them and this will allow me plenty of time to call the incident in and thry keep me safe. They work AMAZING and I tried plenty of different sensors, but these ones are by far the best and they keep a great charge, and even after a few got run over by drivers. Thry still worked. I've been using these now for a year and still haven't changed the batteries. They're totally worth it. I only have to replace once that have been run over by drivers.

Had to buy these to put put near our shed. Someone kept breaking in at night. The alarm works really well and we have had no more issues since installing. Great price, easy to set up and the alarm is loud enough to hear with out being annoying

This arrived quickly and in a nice box. Inside were two motion sensors and the receiver.All requiring batteries which is to be expected. The sensors each use a 9V battery, the receiver uses C. batteries.The ONLY real issue I have is: the battery case covers all required small screws to hold the covers in place and the issue for me was; there were NO Little Screws. None in the units, none in the box, no screws to hold the battery covers in place....I solved this with scotch tape.Next is the mounting of the components.Since every application is going to mount them differently, I wasn't too sore that no mounting hardware was included. Instead I covered the back of each sensor with Gorilla double sided tape, then just stuck them where I wanted. One is attached to the decorative rock face between my garage doors, the second is stuck onto the wood mouldings that trims one of the roll up doors.Both are pointed at each other and about 40 ft away.I back my trucks up toward the garage doors with tools and such inside.As the sensors are pointed, if anyone walked onto my driveway one or the other sensor will pick them up.Which brings me to the Receiver.It's also a well built product that when set to LOW you can hear outside! When set to high you get the honor of being yelled at by the hard of hearing wifeBottom line, it WORKS!For my next phase in "Operation stop the Badguys" we move to one of the more amusing phases... driving the wife a little more nuts with super loud alarms for little to no reason... I ordered another set of these to place in the backyard and along the side yard where we regularly walk to take the trash out, access the BBQ, mow the lawn and feed the dogs. This should be a hoot...Who said quarantine was no fun.... When I grow tired of aggravating my darling wife or after the frying pan shaped swelling subsides from the back of my head, whichever comes first, I plan on placing the 3rd sensor at the walkway approach to the front door. And the 4th unit at the back gate which would only be opened to take the trashcan in and out, unless you were one of The Badguys....To repeat,The bottom line on this product, I liked it enough even without the missing cover screws to order another set.

I purchased the 4VWIN Home Security Driveway Alarm for a small office where I work as an assistant manager. As an AM, I frequently have to run meetings and conduct interviews. I can't see the door from my office, and I'm often having meetings later in the evening when the receptionist is off.It's very frustrating when I'm in my office and someone walks in and there's no one to greet them, we may need to hire another Rec. But until then,I needed a reliable and unobtrusive method of being able to tell the exact moment someone enters the office. I set these up on the floor for now, but I intend to hang them up on the wall for anchorage. No one's kick themed so far, so that's good lol.The 4VWIN Home Security Driveway Alarm comes with 2 sensors and a receiver. I placed the two sensors in such a way that they'd always be able to tell when someone is walking through the door. They work perfectly, and so far no one has tripped over them. You can set the alarm to HI or LOW, which I appreciate because I don't want an alarm blaring through my office every time someone walks through the door. The sensors lights blink when they're activated or "read" something. The receiver lights up when the batteries (not included) need replacing. Not waterproof.All in all, it's a neat cute little gadget, I'm thinking about purchasing another set to monitor my pet's activities during the night and make sure he's not getting into trouble -_-

Appareil peu dispendieux ... très efficace ... Je peux amener dans ma poche le récepteur de signal lorsque je vais dans le garage dans l'arrière cour afin de savoir si quelqu'un se présente è la maison ... Le système est totalement autonome en lui-même ... Aucun fil de branchement est nécessaire ... Je suis très satisfait de ce produit ...

take time to secure properly

works great ...hope for a long time

really works good

I bought same brand local in town worked great until hailstorm broke sensor. Bought this one from here. Exact same brand. This one was crap. Turned it on and it never stopped going off. Was way too sensitive in my opinion. Flies would set it off. After the first night I took it down and in corner of garage.
