1/2 Mile Battery Power Unit

UPDATE : I just did an update a few days ago. It is 4/12/26 and just after midnight. I just caught two intruders and possibly stopped them from doing something. I heard the first two alarms in my driveway go off very quickly one after the other. This has only happened when a bird flies through both sensors during the day. It was late at night so I knew the birds were sleeping. I got up and looked out the window. I saw two dark figures halfway in my driveway. They were just standing there. Shortly after I saw them they walked back out of the driveway. I thought they saw me so wanting to see where they were going, I went out onto the front porch. On the way to the porch my first alarm went off again. When I got on the porch I could see them just standing at the end of the driveway. I could hear then talking to each other but not loud enough to hear what they were saying. One of them walked back into the driveway and stopped when he triggered the second sensor turned around and walked back out. They had seen the eyes flashing in the window so I suspect that is what stopped them the first time. They were testing my system now and I new it. What they didn't know is they saw only what I wanted them to see. A second receiver upstairs alerts me to all alarms on my property. I knew they were there before they knew they were detected. They talked for a few more minutes and then both of them came back into the driveway setting off the first two sensors and kept walking. This is when I spoke up and asked out of the darkness if they had a problem. I heard one of them say no and then both turned around and walked out of the driveway. They just walked off down the sidewalk like nothing happen. I don't know what their true intentions were but I'm very satisfied with how this system worked. In hindsight I truly believe them seeing the light flashing slowed them down long enough for me to react. My only regret is this. I regret forgetting my paintball gun. If I had it on me they would have been in trouble because I was in a perfect spot to let them both have it. Using any chemical agent is against the law in my state for theft. Personal protection only whether from spray or a gun. I am still waiting to hear back on the use of just using paintballs. Check with your state to be sure. Update : I have had this for 5 months now and am just as satisfied as the day I installed them. I wanted to point out some things I think are important. First of all is the batteries. I am using rechargeable batteries and they have lasted through the cold winter here in Maine (sub zero temp) and still working. I have not had to recharge them at all since I installed them. Second thing is the set up. I set up mine in series. If the post man comes to deliver mail to my mail box on the back gate by the garage, I first get a driveway alert. This is followed by a front door alert when he is about half way into the driveway by the walkway that goes to the front door. And when he get to the mailbox on the gate by the garage I get a garage alert. And the reverse as he leaves. This setup let's me know pretty much where they are on my property. Also I can tell if it is a false alert or not. Birds will set off one alert from time to time and two in the series once in a great while but never all three at one time like the mail man. At night the birds are sleeping so I can too. The receiver on this system will work with up to about 30 sensors. More then enough to cover my whole property. Third thing is mounting and placement of your sensors. Mount them between knee and waste high. This will prevent false alerts at night from small animals like cats, skunks, and such. As for where on your property you want to place them, that is up to you. Putting one inside your shed, garage or, other building is a good idea. The only way those will alert you is if someone actually breaks in. 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.

This is an amazing low cost alarm for driveways. We have a longer winding driveway up to our house surrounded by woods in our 14 acre property. Unfortunately the house is situated in such a way that we have no windows looking out to the driveway to see when people/deliveries are coming up to the house. For security purposes and just not being surprised when we have visitors this product fixed these issues for us immediately. We purchases the 2 sensors/one in house notification set. One sensor is set up on the first bend of our driveway - alerting us to a possible visitor and the second one is set up further along the driveway about 20 yards up to give us a second alert for visitors. (this is used to eliminate false alarms set off by local wildlife and birds, if we hear one alarm closely followed by the second alarm SOMEONE is definitely approaching) The other nice feature we like is that you can set each sensor to make a different kind of alarm. The first one says something like "Driveway Alarm" and the second one is a loud car honking sound. So if we hear both of these go off one after the other we know a visitor is coming well ahead of them actually reaching our house. Great for deliveries that need signatures, notification of planned visitors and alarms for possible intruders. Would absolutely buy again!

For the first time in a long time, I'm impressed by a product I purchased from Amazon. When I read the units were rated for 1/2 mile, I laughed a little and said, "yeah right." I have a 450 yard long driveway, which is roughly 1350 feet. I am in a rural area and have already placed a solar operated gate half way up my drive, but still get people coming to my gate quite often. I placed the first camera 750 feet away from the two receivers I have in my home (one top floor and one ground level). The 2nd camera is roughly 500 feet from my home, then the 3rd is approx 400 feet from my home. All three sensors work as expected. The receiver is very loud on level 4, so there is no problem hearing either receiver. Connecting the sensor to the receiver was a breeze, plus adding the 2nd receiver was also super easy. I picked three different tones for each so I'd know which sensor was being tripped. At approx 400 feet my Arlo cameras kick in, so I don't need any of these right on my house, but if you have a long driveway and want notification of wanted and unwanted visitors, this unit doesn't disappoint. The biggest test is going to be false alarms. We'll see how that plays out in the long run and I'll update this post as-needed.

Strongly recommend for the easy setup and reliability. I have this thing about 450’ away and the receiver is inside a metal building. Works reliably. The volume is just right. Super easy to setup. The pieces come connected to each other and you only have to mount the owl outside. I attached it to a tree near the front of my driveway thinking I could move it if needed. Only complaint is the transmitter mount has a tendency to slip and point too low to the ground. I used a screw to hold it in place and no problems since then. Otherwise this thing is great and works consistently.

It works great. Real easy to install. Also will pick up deer.

The product is probably fine but I was under the impression it would have a camera. I was regretful that I had overlooked that or didn’t catch it in the advertisement when I realize it I didn’t open the boxes. I just sent them back. Didn’t feed the needs that I needed.

This motion alert sensor is not only cute, it works GREAT! I bought it to alert us when a delivery comes to our front door, as many delivery companies don’t ring the bell. It’s perfect! No more needing to check email to see if something was delivered. And it has a variety of tones that I have yet to play with! Love this!

UPDATE/EDIT: I'm giving this three stars now due to The fact that routinely going back to manufacturer default "Silent" setting rather a default setting that is At least making a sound, its actually silent on its default setting and that's probably why people think it stops working. I am constantly having to turn its ringer back on because it's resetting itself. Now I do have to admit that my landlord and his electricians have done, shall we say questionable things to my electricity And I could losing power or have fluctuating power to my apartment but i'm not sure thats the case as my other electronics don't always show the evidence that the power is fluctuating. Even if I lose power the fact that its default setting is silent and if it resets due to a power and I plug it back in or it regains the fact that it resets to silent is a major failure in its manufacturing and makes me regret buying this model even though it was very cute. 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.

Best one yet, never misses anyone yet no false alarms. I highly recommend!

Makkelijk te installeren, veel belgeluiden zodat je iets kan kiezen wat bij je past. Werkt top.

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.

Es fácil de instalar y el sonido es fuerte, lo recordable es que si se quiere tener mayor amplitud de sonido se compre 1 extra o más para mayor recepción

Fungerar och var lätt att installera.
