Wireless Motion Sensor Door Chime: Business Entry Doorbell Indoor Alarm | Motion Sensor Doorbell Alarm Buzzer Store Entrance Alert Bell (500Ft Range, 32 Tunes, 5 Level Volume) 1 sensors 1 Receiver

We bought this motion sensor chime to alert us when our dog is waiting by the door inside our garage to come back in the house (she doesn't bark to come in). We love it! The extensive choice of sounds and 5 volume levels are great and so much better than the shrill 'driveway alert' type alarms we've used in the past. The sensor is on a pivot and can be easily adjusted to detect desired motion and minimize false alarms (we've had 100% accuracy). The sensor does not appear to be weather proof and is for interior use only. Our only criticism is that the instructions that come with the sensor are poorly written and incomplete - e.g. there's no mention of installing the batteries, which you have to do BEFORE you assemble the sensor on it's pivot arm. But we figured it out fairly easily and the alarm is otherwise perfect for our needs. Recommend.

This thing works like a charm. I purchased this for my cats to alert me when they want to come in from outside. After leaving my back door opened and finding raccoons in my house was enough for me to be on the hunt for the perfect product. This fits the bill. It has many different tones to choose from. It also has a volume button to control noise but can be really loud if needed. It is very easy to install just basically hang it and plug it in. I now have piece of mind as to what is coming into my home. This was a great find.

works does the job and many sound choices .

PROBLEM: One recent cold Winter day our Alpha Cat Georgie snuck between our legs and went outside without being seen and we didn’t notice until 2300 hours Snack Muster (we have four foster fail cats), which meant Georgie was outside for about six hours. After looking through the entire house, we found him on the back deck urgently requesting entrance. Georgie is a long-haired part Maine Coon Cat, so he probably holed up in one of his favorite hiding spots, but even so the temps were below freezing and he was very grateful to be back in the warmth. He laid in his bed in front of the fireplace the whole night. RESEARCH: Georgie is certainly smart enough to learn how to push a doorbell button, but that would take time to teach him. We wanted to find something that would help right out of the box. We searched for something like a garage door safety mechanism so Georgie could break a laser beam and ring a bell. Unfortunately, the units we saw were either too expensive or too specific to garage doors. It might be possible to retrofit such a unit, but it seemed like there should be an inexpensive Plug and Play solution. SOLUTION: This unit fit the bill more or less perfectly. Mounted low on the door pointed at the spot on the doorstep where Georgie puts his nose when he wants to come in, the unit paired easily with the ringer and neatly announced when Georgie was ready to grace us with his presence in our living space. PROS: Easy set up; lots of tunes to choose from; five volume settings CONS: (1) outdoor unit is TOO sensitive. After initial setup, it detected every tiny movement in the entire yard. Squirrels, birds at the feeders, wind rustling leaves, and more. Luckily the unit has a mute setting that also blinks a warning light when movement is detected. In the attached pics, you’ll see my simple low tech solution of putting electrical tape over 2/3 of the detector and pointing further toward the ground. This worked well and now only triggers movement next to the bottom of the door. (2) there is no compatibility with Google or Alexa or any way to capture a log of detections. This may only be a problem for people like us who like to track trends (we also own two wi-fi connected automatic cat litter boxes that collect lots of data about our Cat Army’s latrine practices. OVERALL IMPRESSION: this unit was overkill for our purposes and needed a little tweaking to dial back the sensitivity. That said, at less than $25, this unit easily solved our problem. We recommend this for any pet owner who needs a similar solution.

not a bad product, works as advertised. Setup was easy. Pro: great price point, good value Con: 1)The unit is very loud, even at the lowest setting. If you are close to it, it's uncomfortable loud. At lowest setting you have only choice of "still too loud" or completely off. 2) The instructions... I have not read so bad "Chinglish" for a while. example: "Note: fixed tone is paired, need to hold the tone-button and volume-button keys for 5s. The next operation is the same as above"... crystal clear, isn't it :) 3) there is no on/off option on the sensor. If you don't need it (let's say, for a week or longer) you need to open the cover and remove one battery. Odd...

Bought this to alert us when the cat wanted in the back door. Wasn't optimistic about it but thought I'd give it a try. It works great. Very sensitive to the arrival of the animal and relieves us from having to check the door all the time. Can adjust the tune for the chime and the volume. It does occasionally get triggered by things other than the cat. but I'll take those "false positives". Very happy with it and recommend it. Only concern is how long the batteries will last on the outdoor unit.

Works great! Using it at my elderly mother’s bedroom door for alerts during the night. Love the sound options and volume control. Worth it!

High quality,works great.

Buena distacioa y gran variedad de tonos lo único es el volumen que pude ser un poco bajo en ciertas circunstancias y la bocina puede distorsiónar un poco los tonos

Me encantó tiene muchos tonos y el volumen es muy bueno muy fuerte es ideal para negocios

Muy bien producto si lo volvería a comprar

Muy útil para saber cuando entran a la tienda, sonidos musicales bien, ya que trae suaves (recomendado)
