Wireless Motion Sensor Door Chime: Business Entry Doorbell Indoor Motion Detector Buzzer (500Ft Range, 32 Tunes, 5 Level Volume) Store Entrance Alert Bell Bed Alarm for Elderly Dementia Patients

This item works perfectly since the location of our home doorbell is far away from where we hang out, and sometimes can’t hear it rings. Having the motion detector outdoors pointing down the walkway leading to the door, and the receiver located in the area where we hang out, we always know when someone is approaching the front door. Giving us a head start getting to the front door. We love it and so does the dog.

I used this at my small business building and I loved that every time the door opened it chimed. Great buy.

Perfect to hear when people come in and out! Adjustable volume with lots of tones to choose from! Simple set up!

I would like a lower minimum volume level. Otherwise the item is as described

I finally installed this so I am alerted when someone comes through my front gate. It's very simple to install. It too me a while to position it properly so it didn't alert me when someone entered/exited my garage (it's next to front gate).I like the variety of alerts you can choose from.

This has come in handy a number of times, so we've ordered another! It has a nice selection of little tunes to choose from for notification. It's been super reliable and easy to use.

Buen proveedor, de confianza, envía muy rápido

This product has a few features I don’t like, ones that I was unaware of when I bought it.1. The sensor itself lights up when it detects motion. But I do not want the sensor to announce itself.2. The receiver settings reset whenever it is unplugged. This is unforgivable. Every such electronic unit should be designed with a CMOS battery, to retain settings when unplugged. This is a big inconvenience.3. The sensor can be powered with a USB cable, but the port used is USB-Micro. Again, unforgivable. No electronics unit should be designed with any kind of USB port other than USB-C. All pre-existing units that were designed with outdated ports other than USB-C should be redesigned. In fact, I know they already have been redesigned, because it’s illegal to sell units with outdated USB ports in the EU. But since I’m in the USA, they sold me the outdated, inferior version.4. The receiver needs one more button, which is a dedicated on/off button. The lack of this button, combined with the lack of a CMOS battery (to retain settings when the receiver is unplugged), leads to even greater inconvenience.I need this unit pretty badly right at the moment, so I will go ahead and use it, but I will be replacing it as soon as possible.Is there a positive? Yes. It does detect motion and cause the receiver to deliver an alert.
