KERUI Wireless PIR Motion Sensor Doorbell - Sound the Alarm When Someone Approaches Your Door

William Manns: This is a perfect use of a motion sensor alarm. A small freezer in the garage holds food and ice cream. Unfortunately, someone would get an ice cream treat and forget to close the freezer door. After this happened 3 times, I bought this motion sensor alarm. It has more than 30 music choices. Each plays about 10-12 seconds. It is a perfect reminder for those in the household to close the door. Everyone likes it.

Amazon Customer: I thought this would be a nice solution, but unfortunately the adhesive is so terrible the product fell down and broke after 1 day! I bought two and this happened to both!!

Michael A.: Works well but not thru glass windows. Mounting bracket doesn’t stay on very well.

Karen Anderson: This door alarm is very helpful with the volume control and the varied tones that sound that ;you can choose.

Jeff C: With two aging dogs in the house, every once in a while I find a "present" on the floor that I didn't ask for. I set up the KERUI motion sensor to monitor the area the dogs use most frequently, and voila! It works like a charm. When the alarm goes off they make a hasty exit, and I have time to take them both out before any accidents happen. This isn't the best quality motion detector, but it does the job and the price can't be beat.

William H White Jr.: The item is small and complies with the specks on the sales information...However.. it is very peculiar and lacks ability to indicate on how, and where, to point to detect possible movement.. In addition it does not have the ability or power to deduct ..any motion.. through glass pains.. It works.. but very lacking in acceptable operations ..as it is advertised to do.. WHW

Leah McNutt: I love that it rotates so I can place the sensor precisely. It also helps if I need to disable it I can just turn it. If you turn it off it may reset the tone and it is hard to set the tones. I find as you go up and down the button it will miss tones even if you are going slow. This one does not come with an adapter cable like other sensors so I can't add/change/delete tones.

Nick: Has work well since purchased in Sept 2021 , its now Jan 2022. It has many chimes, I used the simple "ding dong" . Have used the ones from Radio Shack/The Source for years previously they worked ok but found they would ring sometimes repeatedly, annoying. This has been Very good on batteries as well. I will check up in a year.
Well, it's Oct 2022 it's still working perfectly!

JudzM: I love this little sensor in how well it works, very sensitive, small size, fast ship from seller. My problem is that it is incredibly cheaply made. I won't even use the buttons on it to change the doorbell chime/hello greeting as I'm afraid they will simply break off. I wish the manufacturer would make a quality version of this item as I would happily pay more for it.
