Great product! Easy and affordable security solution. Put it in our front doorway and now it detects anyone on our front steps that doesn't belong there. Alerts us to package deliveries. Liked it so much that I bought a second one a few days later for the back of the house. Highly recommend!

The media could not be loaded. This is loud!! I keep it where I can hear anyone going into my empty guest room which is in the front of my house. Also I have a teenager who was using the window to sneak out! The base stays in my room and so far it’s been great! The quality of sound and functionality of the sensor is amazing! No battery issues to date. Great product, definitely recommend.

Works well. The sensitivity is perfect

Got the single sensor with 2 receivers. The first receiver is about 40 feet from the sensor (which is outside but sheltered from the rain and sun), but inside the building. It works perfectly. The second receiver is about 150-200 feet from the sensor. It is also outside but under cover. I had it slightly around a corner of the building and it didn't work. I had to move it from behind the building so it had a direct unimpeded path between the receiver and sensor and it works fine. It just isn't exactly where I need it.I decided I didn't want to have to keep changing batteries and worrying about the batteries dying, so I plugged them in using the USB ports. By the time I bought 3 USB cables and 3 adapters, it added another $60 to the price, so figure on that or having to buy batteries for the life of the door alarm system (takes AA and AAA batteries, not included).

Our patio leads out to a busy walkway and there is no gate to block people out. We got this as an alarm system to deter potential intruders and to alert us. The sensor was easy to mount to a sliding door frame (comes with double sided tape). Its been up for 5 months and hasn't fallen off (covered patio, not exposed to weather). Any heat signature will set it off so it detects cats, squirrels and people. I wish it had a screw feature for adjusting the angle more accurately to my space instead of the preset notches. The receiver has tons of tunes to choose from and can be heard from the outside when it is set off. The lowest volume setting has woken us up from another room. I love that it also has a light that blinks with adjustable settings. If you power it using batteries, its super easy to move between rooms (bedroom at night, common areas during the day). It comes a stand or it can be wall mounted. Sometimes our friends enter using our patio instead of the front door and its nice to adjust the tune to the "hello welcome" option. This thing is an incredible value compared to what we almost spent by if we had gotten a motion sensor and camera system that charge subscription fees.

Works as stated.

I needed for just the doorway but the range detects too much area. The chime keeps going off when someone stands close to the doorway. Need a way to narrow the detection area.

I do not use this as a driveway or door bell alarm but as an Alarm for my Truck yes Truck,I mounted the transmitter inside the truck on the Driver door,the Receiver is mounted inside my bedroom,when armed open the truck door and the alarm goes off in my bedroom,but you can hear it all through the house,there is also a receiver mounted in the gurage where the would be thief will also hear it,I also have a transmitter mounted inside my RV,this transmitter is paired to the same receivers,open the door of my RV and the alarms go off,The receivers have different color lights,so if the alarm goes off and the receiver flashes Red then I know it is the Truck,if it flashes Green it's the RV.This alarm system has many applications you can use it for,just use your imagination,they work great.
