Great item and good distance range
Delivered quickly well packaged and its Working extremely well ive used it now for 3 days in several different distance areas to my home i purchased this item as i have to leave my vehicle on street parking or surroundings roads near to my home depending on availability to parking spaces why i needed a long distance coverage and this item is working very good to my requirements I also have purchased rechargeable batteries to maintain top power for the signal distance I haven’t had to change them so far but im very impressed with this product but bare in mind other environmental signals and other cctv can effect the signal range i have a camera in my home and it did effect the signal as i tested it to see by unplugging the camera then signal worked perfectly from another street 500/600yards away i would definitely recommend to anyone and the volume / sound options features are great.

Great Product, well worth doing the mods shown
Works a treat, sets off quite a ROW and has extraordinary range. It covers the whole front of the house and drive so picks up movement anywhere. And contrary to another report it always goes off when my electric car arrives, its MOVEMENT that sets, doesn't matter what it is that's moving. The outside receiver unit is made to run on 2xAA 1.5v batteries, which didn't last long; so for £8 I bought a 240v - 5v adapter (on Amazon). Just needed to remove the rear battery cover and drill 2 holes, then cut off the plug on the 5v end of the adapter, solder the ends to the tabs in the back of the unit then seal so to keep water out. Now it will run forever that its got the mains power. I bought two of the sounder units which are for mains electricity - one inside the house and the other outside, via a timer to work mainly in the dark hours. I made sure to waterproof the outside unit as well. Does it work? YES - has woke me up a couple of times. It's inspired me to now add an outside camera.

Excellent communication by seller!
The sensor became over sensitive and triggered falsely +++ after six weeks of good performance. The Seller has immediately sent me a replacement sensor. It works very well on the whole and can recommend.

3 AA Batteries dead in less than 4 days!
Receiver is 15m away. Works fine. Very simple to setup but in the last 6 days, I've had to replace the 3 AA batteries every 3 days. I thought I'd maybe had a bad set of batteries but nope, a new set of leading branded and expensive batteries, voltage checked before I put them in last Thursday and today the following Monday, it's not working. The batteries are dead. After checking daily with another 3 batteries, it's not 4 days , they last 3 days and I've missed the return window. Maybe mine is faulty but it's definitely junk. Can you make a version with a separate cable connected solar panel please.

I need this product for protecting animals literally for dogs, mine is a open space roof type of parking space and this street dogs come and play at night and damage the car cover if I have put them on else scratches the car bonnet and do lot of damages looking for something I have no idea, I have spent more than 3 covers because all of them damaged, costed me more than 7k, I tried to get the motion detection sensor added to the car to scare the dogs but now it’s not available in markets as it is banned by the government, I tried to build something using PNR sensors those litterly gives sounds for any motions at night, after a long sleepless nights I found this product at Amazon this does not work like PNR how ever it works based on hear signals so only a living or a hear source will trigger the signals not the motions, it is so precise for what I need and signals and sounds and really great even the reactive time is excellent, you will see the quality of the product when you touch them good quality of plastics. I liked it works really well, if ordering from India make sure you have suitable adopter it’s in US type plug the receiver. It is a not a PNR that has wide focus it’s like a mono focus where the eye is pointed it will only sense from there, but it is easy to point the eye, since it comes with the ball type of rotation adjustment. I am happy with the product no issues found as of now. Working great Overseas purchase but got the package safe without any damages like regular deliveries.

This alerts us to couriers entering our 9 acre complex through the main gate so a member can greet them and sign documents. Simple to install and works like a champ in our cold winter weather with non rechargeable 1.5 volt lithium batteries installed. This is a quality product with rubber seals on the battery compartment and brass inserts for the stainless machine screws. Just put the batteries in the transmitter and mount it with the provided hardware, plug in the receiver wherever you like in your building and your in business. No programming or anything else. Edit: There is nothing that drives my decision to purchase like reviews which identify vendors which stand behind their product. The driveway alarm comes with a letter from the owner of the company indicating if there is ever a problem just contact them. In my case my alarm was victimized by a torrential rain that lasted for hours. It just pounded down like a fire hose from the sky. The next day my driveway alarm was not working. The system of seals normally capable of keeping rain out had been defeated. To be frank, I was not surprised. I contacted the support email and 3 days later a new outdoor sensor was delivered to me. This time I simply put a small plastic bag over the outdoor sensor unit and snapped it into the bracket. This remains a capable, well built, well supported unit. That rain that came down was like having the unit endure a pressure washer and the vendor still stood behind their product......immediately!!!!
