This 125dB motion sensor alarm works perfectly! The sound is extremely loud — enough to deter any unwanted presence instantly. It activates and deactivates smoothly with the remote control, which is very convenient. The setup was quick and straightforward, and the sensor is responsive and accurate. Whether you're using it for home, garage, or small business security, this alarm gives you peace of mind. For the price and features, it’s a fantastic choice. Highly recommended!

Works like a charm every time! Picks up on even the slightest movement. I have it at my bedroom's door, and I never miss a night's sleep! Highly recommend.

A fantastic motion detection alarm, easy to install, with a very loud alarm sound.I installed it in my garage, mounted on the wall inside the entrance door. It comes with screws and 3M adhesive. To ensure stability, I chose to secure the alarm to a 6-foot-high wall using screws. To avoid frequent battery replacements, I decided to power the motion detection alarm with a USB cable while keeping the batteries as backups (batteries are included with the product) to prevent it from failing to alarm during power outages. After making all the preparations, I walked around to test the installation angle. There were a few small areas where it didn't detect my movement, but adjusting its position slightly towards the ground resolved that issue. I wanted to ensure the security of my garage.It's worth noting that the motion detection alarm has two sound settings. When placed by the entrance, it emits a "beep" sound, functioning as a doorbell. For security purposes, it has a very loud "siren" alarm sound to deter intruders.Additionally, there's a mini remote control primarily used for arming and disarming the alarm. I tested its functionality, and it works great. I arm the alarm when I park my car and leave, and disarm it when I return. This feature is quite convenient.When purchasing, I extensively researched the detailed information of motion detection alarms, and they have a wide range of applications. They are also reasonably priced. If you need an infrared motion detection alarm with a very loud alarm sound, then this product is definitely worth considering.

I'm using this as a catalytic converter alarm for my Honda Element when parked in my driveway at home. I attached it using zip ties to a magnetic camera mount. I put black electricians tape over the sensor on each side to narrow the motion sensing area. I reach under and attach it to the inside edge of the wheel well of the front passenger tire when I park at home. I aim it towards the catalytic converter. Then I put a small cardboard box with a brick in it so it doesn't blow away (gets windy here) under the Element right in front of the alarm device. The box is about 12" x 14" x 5", and I slide the box in on its side, so it's standing up tall enough to block the sensor. It goes right under the catalytic converter, and in front of the alarm. That stops animals from setting it off when they pass under my car at night. (I especially don't want it going off when a skunk passes under my car.) Without the box there, my feet passing on the driver side of the Element will set it off. If someone were to pull the box out, the alarm would go off immediately. It will wake me and the neighbors. It is very loud. When I tested it, neighbors two doors down came out of their house and a person who lives on the block behind me told me he could hear it from inside his house. I'm hoping that the thieves would take off rather than proceeding to crawl under my car with the alarm going. Even if they see the alarm device mounted on the wheel well, it will already be going off and alerting the neighborhood.My catalytic converter has been stolen twice and has been targeted two other times, when the pipe was cut but they didn't get it. It's even been cut through completely with a cat strap on it. I also have a blink camera on a magnetic mount under the car when I park at home, and the second time my catalytic converter was stolen, the thieves got it off in less than 1 minute with two thieves with saws cutting from each end of the cat converter. (They didn't notice the camera.) By the time I got the alert and got to my door, it was too late. I have another camera in front of my house, and from the time they rolled up to the time they took off with my catalytic converter was one minute and 6 seconds. Hoping that an alarm sounding immediately when they move the box out of the way will prevent another theft.I've been using this for about a month and a half. It has the same batteries in it. I arm and unarm it whenever I'm coming and going. It is a little bit of a hassle but it's better than having to replace the catalytic converter again.There are catalytic converter alarms that hook up to the car battery and get mounted under the car. The catalytic converter alarms are quite expensive and have about the same decibels as this. The catalytic converter alarms supposedly take several minutes of movement before triggering the alarm, to avoid it being triggered by animals. I've read it's easy for thieves to just cut the wiring on them.I'm planning on selling the Element. Once I do, I will keep this alarm to use as a back door alarm. It has different options for a loud alarm or a quieter tone. The remote that comes with it also works well.
