1/2 Mile Battery Power Unit

I have bought quite a few products on Amazon through the years, and this one has impressed me the most by far. It not only met my expectations, it exceeded them. I can't say enough, and would give it more then five stars if I could. Even the company very quickly answered any questions I had. The staff at HTZSAFE was professional, and an absolute pleasure to deal with. Understanding how this system works, and your imagination is the key to its success. I bought the package with three sensors and one receiver. My original plan was to put one sensor at the end of my driveway, and the other two at the front and back doors. The receiver was to go in kitchen. I was so impressed with how well this system works, I will be ordering another receiver/receivers and more sensors. Like I said before, understanding how the system works and your imagination is the key. The sensors and receiver are made of plastic, durable, as well as decorative. The sensors have two gaskets that I can see which I pointed to in my pictures. One flat gasket on the battery cover, and what looks like a ring gasket between the two halves of the main sensor body. I read in a review someone had an issue with water getting in the sensor. I used electrical tape to cover the seam on the main body, and silicone gell on the battery cover as added protection against water. The sensors motion sensor is a narrow beam, unlike the typical flood light sensors that have a wide beam. I found that the sensor works best if you mount it at any access points you want to monitor. Aim the sensor between two solid objects if you can. Mine is mounted on the fence, aimed at my hedges 30ft away, set on low. As for false alarms, I get a few. That is because I have sparrows that like to play tag in the hedges and in the driveway now and then. I will also get false alarms when it is very windy. 40mph or greater and/or the leaves on the ground from the trees are blowing around. If it gets annoying I just unplug it until the wind dies down at night. The receiver I have temporarily placed in the kitchen window as you can see in my picture. I am getting a small power strip to mount it more securely. The lights flash when the alarm goes off. My thought was if an intruder saw it, that would let them know they were detected. Possibly be more of a deterrent. You can see this in my short video. I got a second receiver to go in the up stairs hallway outside my bedroom for when I am sleeping at night. It will wake me up if anyone goes where they should not be. I get no false alarms from those sensors. I have this set up so I can tell when I get a false alarm should I get one. My two receivers are more then loud enough to be heard throughout the house. The volume button on the side of the receiver has four settings. They are high, medium, low, and mute. There is a second button on the receiver that controls the selection of which alarm sound you want for a particular sensor. The instruction manual is easy to understand and follow to setup this security system. There are also tutorials, and how to videos online, should you need further help setting this up. In closing I would like to say this. The money I spent on this system and what it can do was well worth it to me. I now have peace of mind and know that my family, house, and belongings are secure. Remember. Understanding how this system works, and your imagination is the key to your success.

I now have several of these and they work great. In my opinion 100% worth it to buy for an option where you don’t have to pay monthly plans for security. Very easy to setup, plenty of alarm sounds to choose from, and the durability seems to hold up great in the rain and cold weather with good battery life. You can set different tones to each separate motion sensor and change the volume on the receiver in case it’s too loud or too quiet which is great. The range on the sensors is actually really good as advertised and with multiple sensors with different ringtones on each one, I can know when someone pulls in the front of my long driveway entrance, when they actually get to my houses driveway, or when motion is detected inside my storage building. If they all were the same sound you wouldn’t know where the motion actually was if you have multiple sensors on one receiver. Would buy again and definitely would recommend to someone else!

We have loved these! Bought them over the summer and have not had to change the batteries, we live in Vermont and the winters are cold but they are holding up nicely in the weather. The sound reach was pleasantly surprising. Easy to figure out and set up, lots of sound options to choose from and works very consistently. We love them.

TO EVERYONE BUYING THESE: BUY LITHIUM BATTERIES IF YOU LIVE WHERE IT GETS COLD OR HOT! If you live in a place where it gets very cold or hot, you MUST buy lithium batteries as alkaline will die right away in the immense cold or hot and lithium AA will be able to withstand the extreme temps. Yes, they are expensive, but this is the difference between your sensor resetting constantly and the receiver resetting to SILENT! The signal strength seems to be ok, but the main problem with it is it seems to reset for no reason, or it could be user error, I do have some electrical issues due to my incompetent landlord hiring incompetent electricians and now my new breaker box is all messed up and not up to code/rooms sharing circuits when they didn't before, when they made a big deal about the old one not being up to code and that was why they felt the need to cut my power without notice to replace it! The bigger problem with that is that when the sensor resets, it resets to SILENT which is about the DUMBEST thing I've ever seen. This is why I think people think theirs aren't working anymore. It's the combination of when alkaline batteries reach a certain extreme temp, the outside sensor will reset, which will reset the inside sensor, and the inside sensor resents to SILENT as a default. That's the most inane thing I've ever heard of! At least default should have been a sound, and not silent. Otherwise, I'm happy with this. I have the sensor set on "low" for what I call the "woo-woo-zone" because I chose the police siren, because I have the sensor to let me know when my landlord is "Creepin' Up Bottoms Up" outside my apartment when he shouldn't be, because he likes to lurk and record things outside on my private porch and whatnot. It's nice, because it will give just "one woo-woo" for delivery persons, and a sustained/repeated "woo-woo" for when someone is lurking, so you know if someone is spending too much time outside on your porch. It's good if you're worried about stalkers, etc. So as a security device, it's working pretty good, but it's not as dependable as I'd want it to be for security so I'm going to go ahead and get a security camera to tie into my existing security system. It was super simple to install, btw. AND I CANNOT REITERATE ENOUGH, BUY LITHIUM BATTERIES FOR IT! DON'T WORRY ABOUT THE COST! YOU ONLY NEED A 4-PACK. Unless you have outdoor weather station sensors, then I would put them in there too, so you get better, more accurate readings for your weather stations.

Working well so far and it's cute too boot! Plenty of chime options - bit shrill on some but helps to hear it. Noise level and options are nice, plus the bonus flashing lights ( but my outlets are low so that might not matter for me ) . It was easy to set up and it does the job alerting me without being too sensitive/ false alarms. Durability looks good ( like it will survive the weathers here but time will tell ).

We have had these a year now and they work great. We live in a rural area and have one a the end of our laneway one at our garage and one at the house. Recommended

Le mie civette sono fantastiche, segnalano i movimenti su ogni lato della casa con un suono diverso, così si sa sempre il percorso di chi cammina in giardino. Molto sensibili, ho dovuto ridurre il raggio a 10 m per quella lato strada, altrimenti segnalava tutti i passanti. Installate circa sei mesi fa, le pile reggono bene. Sono soddisfattissima

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.

Works as described. Recommended.

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!!!!
