The sensors work great and have a wide vew and are sensitive. The receiver has multiple sounds and tones. You can make it silent also with just the light flashing. It works great and is easy to setup.

Works great in my father's room. You can set different sounds on it for the alarm.

quite sensitive, placement important. Inane alarm. Cannot just pick the least annoying ring sound. It cycles through a bunch so you dont know which sensor is activated.

I use 4 of these around the exterior of my home, including in my Arizona room and pointing directly at my front porch. To cover all entry areas.I set each one with a different tone. So I know how close they're getting and where they are,when they 're outside of my home. It's just one layer of a multi layer security system. And to be honest, I love them. I can set them at different tones, different volumes and if I don't want to listen to them, I can set them so they only flash, and I have them set up in a way that I can see em when i'm watching t v. In this arizona heat, I usually get 223 years out of the motion sensors, and the batteries tend to last for a few months at a time. I just used rechargeable batteries. No problem love emmy'

I installed them inside my Shop to detect if anyone comes threw Garage door or man door. Ringer is loud that I can hear it threw out the house. Now for the motion sensors, the range on mine are anything within 8 feet when they work. Placed 1 next to front entrance (regular door) and it activates around 6 feet away. the light comes on but sometimes the ringer doesn't activate. I have walked in and past it within 1 foot of it and nothing. Found the best way to get this 1 to work is to make tons of movement directly in front of it. Had a few times it went off after door was closed and was walking back to house. This room has my large CNC and supplies (metals and wood) the sensor is not facing anything and is in clear sight of the door. Only thing close to it is my dual dust collection system. Originally placed the second 1 exactly 17 feet away from Garage door. I do have tons of larger wood working tools but sensor was above everything and in clear sight of door. I had to actually place a 2x4 from the ceiling down to get it closer to door just to get it working. This one seems to work fine but nothing over 8 feet away. I can come in from door side and it doesn't go off anywhere near the 23 feet in description. The angle of the sensor is not very good I would say maybe a 15 degree arch. I can walk 1 foot on the outside of door and it won't go off. I have just a single garage door in shop to take in and out materials and furniture. I guess I will just have to be happy with my cameras inside my shop. wanted something to alert my if anyone opened the garage door since it's facing a alley way that has lots of traffic and cars. Wouldn't like my thousands of dollars of tools come up missing. I went down to big box store and replaced these and they work perfect. I wouldn't recommend these to anyone unless you have them super close to what you have them facing and not needing a reliable sensor.

Great delivery and works most of the time. Bought the four plus two receivers. Need three batteries for each detectors. Many tunes but most are too long to be of help (don't want to listen to the whole thing). One put under exterior window, won't work inside glass window; rings constantly when wind blows, making it annoying.

Nice units. They work great. Lots of options on sounds and sensor placements. Good range. Thinking of putting a sensor in my mailbox. Hummmm. Good sensitivity as to movement.
